• How u want to open the link? On submit button click? – Developer Commented Jan 7, 2014 at 10:37
• First thing you can do is check wether the data entered is numerical or not. Check isNaN() (javascript) or .isNumeric() (jQuery) functions. – TCHdvlp Commented Jan 7, 2014 at 10:37
• 1 You should move the if statement to the click handler. – Ram Commented Jan 7, 2014 at 10:39
• @ParthoGanguly yes I want to open the link on submit button – Umar Khan Commented Jan 7, 2014 at 10:40

You're going to need something along these lines:

$(document).ready(function(){
    $('#button').click(function(){
         var number = $('#number').val();
         //check if number
         if($.isNumeric(number)){
             if(number >= 1 && number <= 10){
                 //1-10 action
             }elseif(number >= 11 && number <= 20){
                 //11-20 action
             }
         }else{
             //Not a number
         }
    });
});

EDIT: sorry mixed up the format for checking numeric, sorted now :)

use this code:

$( document ).ready(function() {
    $( "#button" ).click(function() {  
      var num = $("#number").val();
      if(!isNAN(num)){
      if (num >= 1 && num <= 10) {
         window.location.href="your url for 1 to 10";
      } else if(num >= 11 && num <= 20) {
         window.location.href="your url for 11 to 20";
      } else {
         //your other code or action
      }
      } else {
         alert("Enter the numeric value");
      }
    });  
});

 <script>
      if ( parseInt($("#number").val()) <11) {
         window.location.href = '/link1';
      } 
      else{
        window.location.href = '/link2';
      }
</script>

 $( document ).ready(function() {
          $( "#button" ).click(function() {   // Replace with Id of the button
          var num = $("#number").val();       // Replace with Id of the textbox
          if(!isNaN(num)){
          if (num >= 1 && num <= 10) {
            window.location.href="your url for 1 to 10";
          } else if(num >= 11 && num <= 20) {
            window.location.href="your url for 11 to 20";
          } else {
            //your other code or action
          }
         }
     });  
 });

Without testing:

    $(function(){
       $('#button').on('click', function(){
         if ($('#number').val() >= 0 && $('#number').val() <= 10)
           location.href = 'blabla';
         else if ($('#number').val() > 10 && $('#number').val() <= 20)
           location.href = 'blabla';
       });
    });
