HTML5 is a language description for constructing Web content, and HTML5 is designed to support multimedia on mobile devices, and its newly introduced syntactic features can support multimedia on mobile devices, such as video, audio and canvas tags, to better accommodate mobile end devices. The new analysis rule enhances flexibility, new attributes, eliminates outdated or redundant attributes, and truly changes the interaction mode of a user and a document. HTML5 gives better meaning and structure to the webpage, and richer tags construct data-driven Web which is more valuable to programs and users with the support of RDFa, micro data, micro formats and the like. The webpage APP developed based on the HTML5 has the advantages of shorter starting time and higher networking speed, and the webpage APP can benefit from the HTML5 APP Cache and has a local storage function. IndexDB (one of the most important technologies is stored locally by html 5) and API description documents. Since the API document of the geocoding function is disclosed, the HTML5 provides more functional optimization choices for web application developers, and brings the advantage of more experience functions. HTML5 provides an unprecedented open interface for data and application access. The external application can be directly connected with the data in the browser, for example, video and audio can be directly connected with microphones and cameras. More effective connection work efficiency, real-time chat based on pages, faster web game experience and more optimized online communication are realized. HTML5 has more effective Server push technology, and Server-set events and WebSockets are two characteristics of the HTML5, which can help us realize the function of "pushing" data to a client by a Server.
The advantage of using HTML5 is primarily that this technology can be used across platforms. For example, you developed a game of HTML5, you can easily migrate to UC open platform, Opera game center, Facebook application platform, and even can launch to App Store or Google Play through the package technology, so that it is very powerful across platforms, which is the main reason why most people are interested in HTML 5. It has long been assumed that the layout (layout) can not be automatically adjusted according to the width of the screen by 'one-time design and universal application' to automatically adapt the same webpage to the screens with different sizes. In 2010, Ethan Marcotte proposed the term "adaptive web page design", which refers to a web page design that can automatically recognize the screen width and make corresponding adjustments. The traditional situation that the website provides different webpages for different devices is solved, such as a mobile version or an iPhone/iPad version. This is done to ensure the effect, but it is cumbersome, several versions need to be maintained, and if a website has multiple portals, the complexity of the architectural design is greatly increased. The game client needs to be updated every time, which is troublesome. However, updating the HTML5 game is just like updating a page, and is a horse, instant update.
The invention provides a file information management method, a file information management system, electronic equipment and a storage medium, which can simultaneously realize the extraction, the marking and the real-time display of the complete style of a stored document and file information, so that the client can obtain the file information at the point of view, and the enterprise information management is more automatic and simpler.
The present invention will be described with reference to specific examples.
Example one
The present embodiment provides a file information management method. Referring to fig. 1 to 3, fig. 1 is a flowchart illustrating a file information management method according to an embodiment of the present application; FIG. 2 is a block diagram of a presentation layer and a wipe layer according to an embodiment of the present application; fig. 3 is a diagram of a presentation effect of a markup layer according to an embodiment of the present application, and as shown in the drawing, the file information management method includes the following steps:
setting step S1: setting a preview layer and a marking layer in a client operation area, and setting a display layer and a marking and selecting layer in the preview layer;
file information extraction step S2: after a PDF file is rendered into a canvas in the presentation layer, extracting file information in the canvas, and arranging the extracted file information in the rendering layer;
file information presentation step S3: the marking layer is attached to the marking layer and displays the file information marked in the marking layer by the client.
In an embodiment, the setting step S1 includes that the display layer is located below the marking layer.
In specific implementation, the display layer is positioned below the marking and selecting layer, the display layer is a canvas drawing snapshot of a source document, is similar to a background picture, and stores all style formats of a file to the maximum extent; the scoring layer is similar to a "word grip".
In an embodiment, the file information extracting step S2 includes:
PDF file processing step S21: js tool is used for rendering the PDF file into the canvas in the display layer, and after the canvas is displayed on the display layer, the file information in the canvas is extracted through the span label;
file information arranging step S22: and arranging the size and the position of the characters in the extracted file information in the arranging and selecting layer.
Js tool, which is open source, Mozilla, is used to directly render PDF files into canvas. Js frame can realize file conversion by pure HTML5 technology, does not need any local support, can be used by any browser support H5, and has good compatibility. If the extraction operation of the browser is required, text paragraphs are required, and when a PDF (portable document format) tool is used and a PDF file is directly rendered into canvas, an API (application programming interface) selected by the text of the browser cannot be called to extract file information. Therefore, the invention extracts the file information in the canvas through the span label to extract the characters in the file information, corresponds each character to the position of the character in the display layer through an absolute positioning mode, and ensures that the size of the characters in the selection layer is the same as that of the characters in the display layer through the scaling function to compare the specific size of the original characters.
In an embodiment, the file information displaying step S3 includes that the labeling layer generates a semi-transparent div box on the marking layer, and displays the file information in the canvas manually marked in the marking layer by the client in the div box.
In specific implementation, as shown in fig. 3, the labeling layer of the present invention records and highlights the content labeled by the user, generates a semi-transparent div box attached to the selection layer, and realizes the effect of keeping the highlight after selection and labeling.
Example two

As shown in fig. 4, the file information management system according to the present invention is applied to the above file information management method, and includes:
the setting unit 51: setting a preview layer and a marking layer in a client operation area, and setting a display layer and a marking and selecting layer in the preview layer;
the file information extraction unit 52: after a PDF file is rendered into a canvas in the presentation layer, extracting file information in the canvas, and arranging the extracted file information in the rendering layer;
the file information presentation unit 53: the marking layer is attached to the marking layer and displays the file information marked in the marking layer by the client.
In the present embodiment, the display layer is established below the sorting layer by the setting unit 51.
In this embodiment, the file information extraction unit 52 includes:
PDF file processing module 521: js tool is used for rendering the PDF file into the canvas in the display layer, and after the canvas is displayed on the display layer, the file information in the canvas is extracted through the span label;
the file information arranging module 522: and arranging the size and the position of the characters in the extracted file information in the arranging and selecting layer.
In this embodiment, the annotation layer generates a semi-transparent div box on the marking layer, and the file information in the canvas manually marked in the marking layer by the client is displayed in the div box by the file information displaying unit 53.
