Javascript：如何将所有“ \\”字符替换为“”

Question

I try to replace "\\" character to empty "" but I can't do it. How to solve it?

Here is my code

abc = abc.replace('\','');

Answer 1

要替换字符串中的所有匹配项，您需要使用带有g标志的正则表达式，

abc = abc.replace(/\\/g, '');

Answer 2

I think you need to escape the backslash:

abc = abc.replace('\\', '');

If you want to replace all occurrences, you can try:

var pattern = '\\\\';
var re = new RegExp(pattern, 'g');
abc = abc.replace(re, '');
