Bitcoin Wallet address validation using Json and bitcoin blockexplorer

Question

I'm trying to validate a bitcoin wallet address. I want it to check against the blockexplorer to see if it's a "valid" address or not. I have written this code but its not working:

function checkAddress(){

  var address = $('#wallet').val();

  $.getJSON('http://blockexplorer.com/q/checkaddress/'+address+'?format=json',{"format":"json"},function(data){

    alert('xxx == '+data);

  });

}

Can someone tell me how to do it?

Answer 1

The URL isn't returning JSON. So instead of using $.getJSON, use $.get or $.ajax.

function checkAddress(){

  var address = $('#wallet').val();

  $.get('http://blockexplorer.com/q/checkaddress/'+address,function(data){

    alert('xxx == '+data);

  });

}

This should work.
