The local data refers to page data displayed in the browser, and the global variable refers to a variable that can be referenced by all objects or functions in the browser.
Further, according to the webpage opened in the browser, the embodiment of the invention utilizes the crawler script to acquire the local data of the corresponding webpage, and utilizes the object function to define the global variable in the browser. Wherein the object function includes global.
Further, the local database refers to a browser database, which is used for storing browser data, and preferably, in the embodiment of the present invention, the local browser is an IndexedDB, and the IndexedDB is created through a web script, such as a JavaScript script.
