为什么Internet Explorer不喜欢这个jQuery? [英] Why does Internet Explorer not like this jQuery?

问题描述

在调试某些在IE中无法使用的jQuery时，我发现了此错误消息:

While debugging some jQuery that is not working in IE, I found this error message:

var item = $("#item_"+ itemArray[itemIndex]).find('a').text().trim();

Object doesn't support this property or method (script.js, line 100, character 2)

character 2对我来说没有意义.根据显示的文本，character 2将是var中的字母a，但是当然没有任何意义.

The character 2 doesn't make sense to me. Based on the text displayed character 2 would be the letter a in var but of course that doesn't make any sense.

(我不应该使用var吗?)

(Should I not use var?)

我知道jQuery在某种程度上可以正常工作，或者脚本无法在我的页面上做到这一点.

I know that jQuery is working to some extent or the script would not have been able to get this far on my page.

推荐答案

IE没有 String.trim() ，则需要 $.trim() (它会使用本机修剪(如果可用)，并在IE中进行仿真)，如下所示:

IE doesn't have String.trim(), you'll need $.trim() (which uses native trim if available, emulates it in IE), like this:

var item = $.trim($("#item_"+ itemArray[itemIndex]).find('a').text());
