JavaScript: BackSlash as part of a string

Question

I have a JavaScript variable that I'm using PHP that is shown in the page source:

var db_1 = 'C:\this\path'; 

When I set the value of the text field with this variable as follows:

 $('#myinput').val(db_1); 

The slashes disappeared, and only the remaining characters remained!

Why is this and how can I return slashes to

Thanks everyone

Answer 1

The backslash is an escape character in JS. They get lost when the string literal is parsed.

You cannot return them because you cannot tell where they are. You need to make sure that they remain in the string first (by representing them using an escape sequence).

 var db_1 = 'C:\\this\\path'; 

Answer 2

You can use:

 echo json_encode('C:\this\path'); 

json_encode can be used as a filter function for some JavaScript code.

Answer 3

Try the following:

 var db_1 = 'C:\\this\\path';
