How do I replace unicode character u00A0 with a space in javascript?
提问by Wryte
I'm looking to replace a bad character that a content editable div uses when a space is added at the end of the input.
我希望替换在输入末尾添加空格时内容可编辑 div 使用的坏字符。
Here is what I've tried
这是我尝试过的
var text = $(this).text();
text.replace(/\u00A0/, " ");
But when I check the value of the last character like this
但是当我像这样检查最后一个字符的值时
text.charCodeAt(text.length-1)
The value is still 160 instead of 32
该值仍然是 160 而不是 32

In javascript strings are immutable and replace return new string, try this:
在 javascript 字符串是不可变的并替换返回新字符串，试试这个：
var text = $(this).text();
text = text.replace(/\u00A0/, " ");
or in one line:
或在一行中：
var text = $(this).text().replace(/\u00A0/, " ");
also if you want to replace all instances of the character you need to add g to the regex /\u00A0/g
此外，如果您想替换字符的所有实例，则需要将 g 添加到正则表达式 /\u00A0/g
