Hi,

I need a urlencode function in javascript. I couldnt find one. Is it really true that there is none???

I tried following, but doesnt work. Might be because I dont know how to program RegEx).

    function urlencode(text) {

      text.replace(///,"%2F");
      text.replace(/?/,"%3F");
      text.replace(/=/,"%3D");
      text.replace(/&/,"%26");
      return text;
    }

(I only need those 4 characters encoded)
whats wrong with it?

1. your function (this is a joke so...)

function urlencode(string)
{
return escape(string)
}

2. the answer, of course is, yes, there is a function, it is called escape and unescape.

if you want to see what was wrong with your  regexp


function urlencode(text) {

     text= text.replace(/\//g,"%2F");
    text= text.replace(/\?/g,"%3F");
   text=  text.replace(/=/g,"%3D");
  text=   text.replace(/&/g,"%26");
     return text;
   }


the above will work.

problems w/ yours:

1. wern't assigning result back to text
2. weren't escaping special characters
3. you need to use the g modifier incase you have a string with 2 of any of the above.

Good luck
