Set background based on SPAN contents

I need to set a different background image dependant on the contents of a SPAN:

<div class="replies">
<span>2</span>
</div>

If SPAN = 1 background-image: url('reply.png') no-repeat;

If SPAN = 'anything other than 1'开发者_StackOverflow background-image: url('replies.png') no-repeat;

Can this be done in jQuery?


should be easy going

$(document).ready(function(){
    var span = $('.replies').find('span').text();
    if(span === '1')
       $(this).css('background-image', 'url(\'reply.png\') no-repeat');
    else
       $(this).css('background-image', 'url(\'replies.png\') no-repeat');
});


Yes, you can loop through the elements, get the span inside and check the contents:

$(function(){
  $('.replies').each(function(){
    var img = 'replies.png';
    if ($(this).find('span').text() == '1') {
      img = 'reply.png';
    }
    $(this).css('background-image', 'url(' + img + ') no-repeat');
  });
});


Take

$("div.replies > span").text() and check that aginst "1"

var spanText = $("div.replies > span").text();

if ( spanText === "1" )
{
    // change bg image
}
else
{
    // another bg image
}
