为什么IE7不认为这两个字符串是平等的？(Why doesn't IE7 think these two strings are equal?)

我有一个事件处理程序，将从相应的复选框的列表中删除一个元素未选中。在复选框的click事件处理程序中，首先复制该复选框的标签值：

var label = $(this).next().html();

然后，我迭代列表项并将它们与标签进行比较：

$("#sortable li").each(function() { if ($(this).html() === label) { $(this).remove(); } });

在Internet Explorer 8和Firefox中，它的工作原理与我所期望的完全相同。在Internet Explorer 7中，它没有。 “if”语句中的条件从来就不是真的。我在这里错过了什么？

通过请求，比较的字符串是“Charge”和“Charge”。

I have an event handler that will remove an element from a list of the corresponding checkbox is unchecked. In the handler for the click event for the checkbox, first I copy the value of the label for that checkbox:

var label = $(this).next().html();

Then, I iterate over the list items and compare each of them to that label:

$("#sortable li").each(function() { if ($(this).html() === label) { $(this).remove(); } });

In Internet Explorer 8 and in Firefox, this works exactly as I'd expect. In Internet Explorer 7, it does not. The condition in the "if" statement is never true. What am I missing here?

By request, the strings being compared are, "Charge" and "Charge" in one case.
