omiting number sign using regex in java script not working

Question

I have written a simple code in a .js file (in Zend framework, but I dont think it matters)

var location = "localhost:8080/mymodule/id/1#";
location.replace(/\#/g, "");
alert(location.valueOf());
return;

but I dont know why I can not see the result I want. I get my page url and want to omit all number signs appears in it. but the code above does nothing. please help

location is a bad name to use for a variable since it collides with the window.location variable used for the actual browser page location.

If you change location to loc in your above code, and then also add loc = in front of the loc.replace() call (since replace() doesn't modify the input, but instead returns the new version), your code works.

replace will not change the value of the original string, you need to assign the result to a new variable -

var newString = location.replace(/#/g, "");
alert(newString);

Why are you escaping the `#`? – tchrist Aug 27 '11 at 11:53
I'd just copied from the original question, removed now. Thanks for pointing it out. – ipr101 Aug 27 '11 at 11:59

It can be done in one line. This is the result you look for?

alert("localhost:8080/mymodule/id/1#".replace(/#/g,'')); 
  //=> alerts 'localhost:8080/mymodule/id/1'
