1. When developing a mobile application, it is necessary to pre-load the page to be linked. Because when a linked page is set to a pre-load mode, the target page is automatically loaded to the current document after the current page is loaded. You can click it to open the page immediately, this greatly speeds up page access. 2. Set the link page to pre-load, add the data-prefetch attribute to the <a> label, and set the attribute value to true. To implement page pre-loading in JQuery Mobile, another method is to call the global method $. mobile. loadPage () in JavaScript code, which has the same effect as data-prefetch. 3. Sample Code: <!
