Question

I need to parse url in JavaScript.

Here is my code:

var myRe = /\?*([^=]*)=([^&]*)/;
var myArray = myRe.exec("?page=3&Name=Alex");


for(var i=1;i<myArray.length;i++)
{
    alert(myArray[i]);   
}

Unfortunately it only works for first name=value pair.

How I can correct my code?

Answer 1

exec returns a match, or null if no match found. So you need to keep execing until it returns null.

var myRe = /\?*([^=]*)=([^&]*)/;
var myArray;
while((myArray = myRe.exec("?page=3&Name=Alex")) !== null)
{
  for(var i=1;i<myArray.length;i++)
  {
      alert(myArray[i]);   
  }
}

Also, you’re regex is wrong, it definately needs th g switch, but I got it working using this regex:

var regex = /([^=&?]+)=([^&]+)/g;
