通过$(this)来获取当前触发事件的元素节点。 // 事件委托绑定事件到父元素上$(document).on('click','.dynamic-element',function(){// 在事件回调函数中获取动态添加的元素节点varclickedElement=$(this);// 通过jQuery选择器获取动态添加的元素节点vartargetElement=$('.target',clickedElement);// 进行相关操...
'); }); // 绑定多个事件 $('#myInput').on({ focus: function() { $(this).addClass('focused'); }, blur: function() { $(this).removeClass('focused'); } }); // 使用事件委托 $(document).on('click', '.dynamicElement', function() { console.log('动态添加的元素被点击了!');...

If you create another element later and add it to the page, the event handler will not be attached.Use a delegated event handler instead:複製 $(function(){ $(document).on("click", "ul.cls-ul li", function(e) { alert(this); }); }); ...
$("button.alert").on("click", function () { console.log("A button with the alert class was clicked!"); }); // Now create a new button element with the alert class. This button // was created after the click listeners were applied above, so it ...
jQuery jQuery代码及功能: functionjq(){ alert($("div").index(document.getElementById('test1'))); alert($("div").index(document.getElementById('test2'))); } 运行:当点击id为test的元素时,两次弹出alert对话框分别显示0,1 size() Length 说明:当前匹配对象的数量,两者等价 ...
=typeof b.getElementById&&p){var c=b.getElementById(a);return c?[c]:[]}},d.filter.ID=function(a){var b=a.replace(ba,ca);return function(a){return a.getAttribute("id")===b}}):(delete d.find.ID,d.filter.ID=function(a){var b=a.replace(ba,ca);return function(a){var c...
When the requested page loads, jQuery Mobile parses the document for an element with the data-role="page" attribute and inserts that code into the DOM of the original page. Next, any widgets in the incoming page are enhanced to apply all the styles and behavior. The rest of the incoming...
