jQuery Mobile - 可过滤的预呈现
描述
可过滤小部件在启动期间执行一次过滤器,以确保子列表返回搜索输入中输入的值。 为防止这种情况,请指定 data-enhanced = "true" 属性。
每当此属性设置为 true 时,都假定您已将 uiscreen 类正确应用到那些最初必须隐藏的子级。 可过滤小部件使用搜索输入来确定搜索输入是否已预呈现。
以下示例预呈现搜索输入和可过滤项。
示例
以下示例演示了在 jQuery Mobile 中使用可过滤预呈现。
<!DOCTYPE html> <html> <head> <title>Filterable Pre-rendering</title> <meta name = "viewport" content = "width = device-width, initial-scale = 1"> <link rel = "stylesheet" href = "https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css"> <script src = "https://code.jquery.com/jquery-1.11.3.min.js"></script> <script src = "https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script> </head> <body> <form> <div class = "ui-input-search ui-body-inherit ui-corner-all ui-shadow-inset ui-input-has-clear"> <input data-type = "search" data-enhanced = "true" data-inset = "false" id = "pre-rendered-example-input" placeholder = "search cars..." value = "or" /> </div> <div data-role = "controlgroup" data-enhanced = "true" data-filter = "true" data-filter-reveal = "true" data-input = "#pre-rendered-example-input" class = "ui-controlgroup ui-controlgroup-vertical ui-corner-all"> <div class = "ui-controlgroup-controls"> <a href = "#" class = "ui-btn ui-corner-all ui-shadow ui-shadow ui-screen-hidden">Audi</a> <a href = "#" class = "ui-btn ui-corner-all ui-shadow ui-first-child ui-shadow ui-last-child">Ford</a> <a href = "#" class = "ui-btn ui-corner-all ui-shadow ui-shadow ui-screen-hidden">Hyundai</a> <a href = "#" class = "ui-btn ui-corner-all ui-shadow ui-shadow ui-screen-hidden">Tata</a> </div> </div> </form> </body> </html>
输出
让我们执行以下步骤,看看上面的代码是如何工作的 −
将上述 html 代码保存为服务器根文件夹中的 filterable_prerendering.html 文件。
将此 HTML 文件打开为 http://localhost/filterable_prerendering.html,将显示以下输出。
