如何使用JavaScript从字符串中删除\\（反斜杠）符号？

Question

how to remove \\ (backslash ) symbol from string using javascript

var str ='Visit\ Microsoft \'; 

var res = str.replace(/\//g, "-");
alert(res);

Answer 1

Use:

str.replace(/\\/g, "-");

So you need to use backslash ( \\ ) instead of forward slash ( / ).

Answer 2

it should be

var str = 'Visit\\ Microsoft \\';

var res = str.replace(/\\/g, "-");
alert(res);

you need to escape the \\ with another \\ as back slash is a escape character, also the regex should be /\\\\/g

Demo: Fiddle

Answer 3

另一种方法。

str = str.split('\\').join('').trim()

Answer 4

var str ='Visit\\ Microsoft \\'; will not work, coz its invalid..

var str ='Visit\\\\ Microsoft \\\\'; -- is the correct js string

Answer 5

Have you noticed the color change in your HTML Code?

var str ='Visit\ Microsoft \'; 

var res = str.replace(/\//g, "-");
alert(res);

Everything after Microsoft is red, that indicates everything after Microsoft is also a string.

\\ Backslash works as a except character , So it except closing " ' " mark.

Please check your code, you may need to add backslash before Space, like below

var str ='Visit\ Microsoft\ '; 

var res = str.replace(/\//g, "-");
alert(res);

This Code will work as you wanted.
