Dynamic value in pattern

[sandy1028]

How to make "hints" as dynamic varaible:

 

 

var myRegExp = /hints\s=\s'(.+?)';/;

 

I am trying to use as 

var myRegExp = "/"+hints+/\s=\s'(.+?)';/; 

which doesnt work.

You can't use variables in a regex literal. You need to create a new RexExp object to do it.

 

Example:

var hints = 'foobar';
var myRegExp = new RegExp(hints+"\\s=\\s'(.+?)';");

console.log(myRegExp); 
// output: /foobar\s=\s'(.+?)';/

Also note the necessity to double escape backslashes.
