Description

Text input method, equipment, device and storage medium for supporting backspace input method
Technical Field
The invention relates to the technical field of text input, in particular to a text input method, text input equipment, a text input device and a text input storage medium which support a backspace input method.
Background
In some software text entry boxes, it is sometimes set to allow only certain types of character entry, such as only numbers for some fields in the scale management software. For example: the product number, shelf life, etc., which are common practice in the industry. To prevent fool-proofing, scale management software typically makes input restrictions on such text entry boxes to prevent users from entering characters other than digits.
In the prior art, the text input box only allowing to input numbers is processed in the following way: when the keyboard is used for typing a value, the function of only allowing the input of a number is realized by judging whether the current typing value is a number or backspace and if not, setting the typing value to be #0 (namely: a null character). However, the prior art risks losing valid information in the face of input methods that produce a back-delete key.
Taking the vietnamese character as an example, the vietnamese alphabet refers to 5 tones in addition to the commonly known a to Z. For example, the alpha letter has various tones:
Figure BDA0003755941430000011
and the like. A commonly used input method tool in vietnam is unikey, which is done by combining key patterns in inputting letters with special tones. Such as input
Figure BDA0003755941430000012
Is achieved by pressing a two times. Also for example, inputting letters
Figure BDA0003755941430000013
Is achieved by pressing the letters a and w.
Although seemingly, unikey looks like pinyin, the letters are combined and the corresponding value is printed. But in practice unikey is used when inputting letters, e.g.
Figure BDA0003755941430000014
The principle is that when a is pressed for the first time, the input method outputs the key value of a character (namely, a is input in a text box); when pressing a for the second time, the input method firstly outputs the key value of backspace character (backspace) (namely deleting a in the text box), and then outputs
Figure BDA0003755941430000015
Key value of character (i.e. enter in text box)
Figure BDA0003755941430000016
)。
Existing scale management tools are using Unikey inputIn the method input, when only the input number is allowed to input the letter with tone by mistake, an error value is generated, so that the normally input number is deleted. For example: input pressed a two times after 123 (i.e.: error input)
Figure BDA0003755941430000021
) In this process, the Unikey input method will input three ASCII codes into the text input box: #97 (i.e., a), #8 (i.e., backspace), and #226 (i.e.:
Figure BDA0003755941430000022
). Wherein, #97 and #226 would be set to null values without generating an enter action because they do not belong to digits and backspace, and #8 would generate a backspace action to delete 3 of 123 normally entered previously.
In view of the above, the applicant has specifically proposed the present application after studying the existing technologies.

The invention is described in further detail below with reference to the following detailed description and accompanying drawings:
the first embodiment is as follows:
referring to fig. 1 to 4, a text input method supporting a backspace input method according to a first embodiment of the present invention is executed by a text input device (hereinafter, referred to as an input device) supporting a backspace input method. In particular, execution by one or more processors in the input device to implement steps S1, S2, S3, and S6.
S1, obtaining a current input character of a text input box. Wherein the text input box is a pure number input box.
Specifically, the embodiment of the invention starts to execute when the text input box selected by the user is the input box in the pure digital format, and judges and processes the key value output by the input method after the user presses the keyboard, so that the operation executed on the text input box is determined, and the operation of mistakenly deleting the characters in the text input box can be effectively avoided.
It will be appreciated that the input device may be an electronic device with computing capabilities such as a laptop computer, desktop computer, server, smart phone or tablet computer.
And S2, judging the type of the current input character. Wherein the types include numeric, backspace, and other character types.
Specifically, the key value of the current input character is an ASCII code. In this case, the encoding of the backspace is #8, and the encoding of the number is #48 to #57, and in the present embodiment, the ASCII code other than the above-described encoding is set to other character types. In other embodiments, the decimal point, slash, bar, and other symbols may also be included in the numeric type, and the present invention does not limit the specific codes included in the numeric type as long as the present invention can divide the ASCII code into three types, i.e., backspace, text input box supported type, and text input box unsupported type, which belong to the protection scope of the present invention.
In this embodiment, the type of the currently input character is directly determined, so as to determine the type of the currently input character. In other embodiments, this step may be split into two steps, namely: judging whether the currently input character is one of the three types, and judging whether the currently input character is another of the three types after judging that the currently input character is not one of the three types.
Specifically, step S2 is: it is determined whether the currently input character is of the first character type. And when the currently input character is judged not to be the first character type, judging whether the currently input character is the second character type. Wherein the first character type is one of numeric type, backspace type and other character types. The second character type is another one of numeric type, backspace type and other character types.
Preferably, step S2 is: judging whether the current input character is of a backspace type; when judging that the current input character is not of a quit lattice type, judging whether the current input character is of a numeric type or not; or judging whether the current input character is of a numeric type; and when the current input character is judged to be not the numeric type, judging whether the current input character is the backspace type.
It can be understood that the type of the currently input character is judged by steps, so that the instantaneous calculation amount required by the step can be effectively reduced, and the input equipment is prevented from being jammed.
And S3, when the type of the current input character is judged to be a backspace type, acquiring the historical input character, and judging the type of the historical input character. Wherein the historical input characters are characters input last time.
Specifically, like step 2, in this embodiment, the type of the history input character is directly determined, so as to determine the type of the history input character. In other embodiments, this step may be split into two steps, namely: judging whether the currently input character is one of the three types, and judging whether the history input character is another of the three types after judging that the type of the history input character is not one of the three types.
Specifically, step S2 is: it is determined whether the historical input character is of a first character type. When it is judged that the history input character is not the first character type, it is judged whether the history input character is the second character type. Wherein the first character type is one of numeric type, backspace type and other character types. The second character type is another one of numeric type, backspace type and other character types.
Preferably, step S3 is: judging whether the historical input characters are of a backspace type or not; when judging that the historical input character is not in a lattice withdrawing type, judging whether the historical input character is in other character types or not; or judging whether the historical input characters are of a digital type; when the historical input character is judged not to be of a numeric type, judging whether the historical input character is of a lattice withdrawing type.
It can be understood that the instantaneous calculation amount of the input device can be reduced by performing the judgment step by step, so that the text input method provided by the embodiment of the invention can be executed in a text input device with a lower configuration in a smoother manner, and better use experience can be obtained.
As shown in fig. 2, on the basis of the above embodiment, in an optional embodiment of the present invention, step S3 is followed by steps S4 and S5.
And S4, writing the current input character into the text input box when the type of the current input character is judged to be a numeric type.
And S5, setting the current input character as a null value when judging that the type of the current input character is other character types.
It is understood that, in other embodiments, when it is determined that the type of the currently input character is a numeric type or other character type, other artificially defined actions may also be performed, which is not specifically limited by the present invention.
And S6, setting the current input character as a null value when the type of the historical input character is judged to be other character types.
Specifically, in the input method of unikey et al that generates backspace, the action of generating redundant backspace is always in the middle of two letters, which belong to other character classes in the embodiments of the present invention. Therefore, when the type of the current input character is judged to be the backspace type and the type of the historical input character is judged to be other character types, the embodiment of the invention sets the current input character to be a null value, thereby eliminating redundant backspace actions caused by an input method.
By the embodiment of the invention, when the backspace input method is used for inputting the text input box in the pure digital format, the condition that backspace generated by the backspace input method due to specific conditions deletes characters in the text input box can be effectively avoided, and the problem of effective information loss is avoided.
As shown in fig. 2, on the basis of the above embodiment, in an optional embodiment of the present invention, step S7 is further included after step S6.
And S7, deleting the last displayed character in the text input box when the type of the historical input character is judged to be a numeric type or a backspace type.
It is understood that, in other embodiments, when the type of the history input character is determined to be a numeric type or a backspace type, other artificially defined actions may also be performed, which is not specifically limited by the present invention. The present invention is within the protection scope of the present invention, as long as it can set the current input character to null value when the type of the current input character is backspace type and the type of the historical input character is other character type, thereby eliminating redundant backspace actions caused by the input method.
Based on the above embodiments, in an optional embodiment of the present invention, the historical input characters default to null values. Preferably, step S0 is further included before step S1.
And S0, when the text input box is selected, setting the historical input characters to be null values.
Specifically, the text input method of the embodiment of the invention is executed after the user selects the text input box only supporting the numeric type, and the historical input characters are set to be null values when the text input box is just selected, so that the misjudgment of the input of the current text input box caused by the user inputting characters in the last text input box can be avoided.
It will be appreciated that in embodiments of the invention, null values act the same as digit and escape modes. Namely: and deleting the last displayed character in the text input box when the type of the current input character is a backspace type and the type of the historical input character is a null value.
On the basis of the above embodiment, in an optional embodiment of the present invention, step S7 is followed by steps S8 and S9.
And S8, updating the historical input characters into current input characters, and judging whether to exit the current text input box.
And S9, when judging that the current text input box exits, ending the input of the current text input box. Otherwise, the current input character of the text input box is continuously received.
It can be understood that after the processing of the current input character is judged and executed, the judged and executed processed current input character is assigned to the historical input character, so that the historical input character can be quickly acquired when the next character is input, and the method has good practical significance. In other embodiments, the key values of the historical input may be recorded in other manners, and how to obtain the historical input characters is not specifically limited in the present invention.
