将jquery .text()匹配到& nbsp; [英] Matching jquery .text() to  

问题描述

由于SharePoint无法控制的情况，我有以下代码.

Due to circumstances out of my control, SharePoint, I have the following piece of code.

var item = $('<span><font size=1>&nbsp;</font></span>').text()

我正在尝试将.text()值与 进行比较，但不知道该怎么办.单步执行代码item似乎等于"，这很有意义.但是执行item == " "会返回false.应该如何进行比较?

I am trying to compare the .text() value to   and don't know what to do. Stepping through the code item seems to equal " " which makes sense. But doing item == " " returns false. How should this comparison be done?

尝试检查'\xa0'(这是 创建的字符):

Try checking for '\xa0' (which is the character created by  ):

var item = $("<span><font size=1>&nbsp;</font></span>").text();
alert("'" + item + "' " + (item == '\xa0'));
