绑定JQuery中动态元素的click事件

问题描述：

我有一个div，它通过.html属性

I have a div which is filled dynamically after calling an AJAX call by .html attribute

$("#gallery").html(imagesHtml);

独立imagesHtml我现在有2个分别称为"prebtn"和"nxtbtn"的按钮，我正在尝试使用JQuery中的以下语法绑定这些按钮:

insdie imagesHtml i ahve 2 buttons called "prebtn" and "nxtbtn" now I'm trying to bind these buttons with the following syntax in JQuery:

$("#gallery").bind('click', '#nxtbtn', function() {
    alert('next');
});

和

$("#gallery").bind('click', '#prebtn', function() {
    alert('previous');
});

但是当我单击其中一个按钮时，两个事件都被触发，并且显示下一个"和上一个"的提示；但是，我只单击了其中一个按钮！

but whener I click on one of the buttons both events get triggered and it shows allert for "next" and "previous"; howevr I have click just one of the buttons!

如果需要更多说明，请告诉我.

Please let me know if you need more clarification.

谢谢

答

您正在混淆 bind 和 on 方法.它们看起来很相似，但是bind的功能较少:它不支持事件委托.第二个参数不是委托事件的选择器，而是data参数.

You're confusing the bind and on methods. They look similar, but bind has less functionality: it does not support event delegation. The second argument is not the selector for the delegated events, but a data argument.

这将起作用:

$("#gallery").on('click', '#nxtbtn', function() {
