JavaScript.click 在 IE 11 中不起作用

Question

我一直在尝试让此代码适用于动态 crm 的多个 select 选项集。我的问题是这段代码在 Chrome 中毫不费力地工作，完全符合我的要求，但在 IE 中，.click 事件 returns false 无论如何，如果复选框被选中或未选中。

所有这些代码所做的就是获取一个选项集并将其转换为多 select 列表并将值设置到两个字段中 "l1s_trainingmodulesvalues" 保存选项的值 selected "l1s_trainingmodules" 保存选项的标签 selected.

有人可以看看我做错了什么吗？

Answer 1

您的 checkbox 变量没有引用复选框元素。这是一个标签 (var checkbox = "<label><input type=\"checkbox\" name =\"r\">" + rText + "<br></label>")，没有选中状态。

在您的 click 处理程序中，更改

if ($(this).is(':checked'))

到

if ($(this).find('input').is(':checked'))
