Thanks for your help!

$(function() {
  $('.star-one').live("click",function() {
    $("#rate_result").html('1');
    $("#star1").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
  });

  $('.star-two').live("click",function() {
    $("#rate_result").html('2');
    $("#star1").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
    $("#star2").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
  });

  $('.star-three').live("click",function() {
    $("#rate_result").html('3');
    $("#star1").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
    $("#star2").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
    $("#star3").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
  });

  $('.star-four').live("click",function() {
    $("#rate_result").html('4');
    $("#star1").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
    $("#star2").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
    $("#sta开发者_高级运维r3").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
    $("#star4").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
  });

  $('.star-five').live("click",function() {
    $("#rate_result").html('5');
    $("#star1").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
    $("#star2").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
    $("#star3").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
    $("#star4").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
    $("#star5").html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
  });
});

Here is the html:

<div id="rate_result"></div>
<div id="stars-container">
  <ul class='star-rate'>
    <li id="star1">
      <a href='#' title='' class="star-one" id="1">mmmm</a>
    </li>
    <li id="star2">
      <a href='#' title='' class="star-two" id="2">try again</a>
    </li>
    <li id="star3">
      <a href='#' title='' class="star-three" id="3">mmm not bad</a>
    </li>
    <li id="star4">
      <a href='#' title='' class="star-four" id="4">this is cool ya!</a>
    </li>
    <li id="star5">
      <a href='#' title='' class="star-five" id="5">very good</a>
    </li>
  </ul>
</div>


Here's a bit of compression:

$(function() {
    var star_tag = '<img src="http://larsonreviews.com/rating/star_ena.gif" border="0" alt="*">';
    $('.star-one').live("click",function() {
        $("#rate_result").html('1');
        $("#star1").html(star_tag);
    });
    $('.star-two').live("click",function() {
        $("#rate_result").html('2');
        $("#star1, #star2").html(star_tag);
    });
    $('.star-three').live("click",function() {
        $("#rate_result").html('3');
        $("#star1, #star2, #star3").html(star_tag);
    });
    $('.star-four').live("click",function() {
        $("#rate_result").html('4');
        $("#star1, #star2, #star3, #star4").html(star_tag);
    });
    $('.star-five').live("click",function() {
        $("#rate_result").html('5');
        $("#star1, #star2, #star3, #star4, #star5").html(star_tag);
    });
});


add a class called star to each star

$('.star').live("click",function() {
$("#rate_result").html($(this).prevAll('.star').length+1);
$(this).prevAll('.star').addClass('enabled') // where enabled would add a background image(like star_ena.gif)
});


Perhaps this will give you an idea how you can compress your code a bit:

Turn a number into star rating display using jQuery and CSS

That code currently turns numbers to stars but can easily be adapted to handle click events for changing the value.

There's no need to do separate img elements for each star, only thing you need is two spans which have the stars as an background image and then just apply a proper width to those spans.


Create a loop for 1 until #rate_result and ouput $("#star" + count).html('<img />');


Step 1:

Create 1 variable to hold the url string:

var img = '<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">';

then replace all those strings with your variable.

$("#star1").html(img);


Untested, but I'd guess this would work.

$(function() {
var textrep=new Array("zero","one","two", "three", "four", "five");
for (i=1; i<=5; i++)
{
$('.star-'+textrep[i]).live("click",function() {
$("#rate_result").html(i);
for (j=1; j<=i; j++)
{
    $("#star"+j).html('<img src="http://larsonreviews.com/rating/star_ena.gif" border="0">');
}
});
    }
});
