jQuery事件侦听器在IE 7/8中不起作用 [英] jQuery event listener doesn't work in IE 7/8

问题描述

问题有点棘手.我的代码无法动态加载表中的表行，然后将事件附加到所有表"单元格，但在IE7/8中不起作用.但是有时它确实没有明显的原因.

the problem is a bit tricky. My code to dynamically load table rows inside a table and then attach events to all the Table cells doesn't work in IE7/8. But sometimes it does work for no apparent reason.

这里有一个小样本: http://jsbin.com/ivarus/6/edit

这是我在应用程序中所做的简化版本

This is a simplified version of what I'm doing in my app

以下是进行复制的确切步骤: 1)打开IE并从开发工具中将其设置为IE7/8(如果您已经在运行IE8，则无需这样做) 2)导航到 http://jsbin.com/ivarus/6/edit 预期:与TD相关的点击在输出"部分中起作用 实际上:只有在按下运行脚本"后，事件监听器才能开始工作

Here are the exact steps to repro: 1) Open IE and set to IE7/8 from dev tools (not necessary if you're already running IE8) 2) Navigate to http://jsbin.com/ivarus/6/edit Expected: clicks attached to TD work in the Output section Actually: the event listeners start working only after pressing "Run script"

在所有其他浏览器(IE9 +，Chrome，FF)中，此操作立即生效.为什么?我做错什么了吗?我应该寻找一种替代方法吗?

In all other browsers (IE9+,Chrome,FF) this works immediately. Why? Am I doing something wrong ?Should I look for an alternative approach ?

推荐答案

在脚本运行之前，您需要等待文档就绪事件.像这样封装您的代码.

You need to wait for the document ready event before your script runs. Enclose your code like this.

<script>
$(function ()
    {
        //your code here
    });
</script>
