I use a for loop to show all elements via jQuery in this one

  • 0

I use a for loop to show all elements via jQuery in this one function: 

<script> 
$(function() {
    var number_menus = 9;
    for (i = 1; i <= number_menus; i++) {
        var p1 = +i;
        $(".wm_" + i).show()
            .css("background-image", "url(imagenes/footer/m/" + i + ".png)");

        $(".wm_" + i).mouseover(function() {
            $(this).css(
                "background-image", 
                "url(imagenes/footer/m/" + i + "_down.png)"
            );
            alert("this_down.png");
        });

        $(".wm_" + i).mouseout(function() {
            $(this).css(
                "background-image", 
                "url(imagenes/footer/m/" + i + ".png)"
            );
        });
    }
});​
</script>

  <div id="web_footer_marks" class="wm_1"></div> 
  <div id="web_footer_marks" class="wm_2"></div> 
  <div id="web_footer_marks" class="wm_3"></div> 
  <div id="web_footer_marks" class="wm_4"></div>
  <div id="web_footer_marks" class="wm_5"></div> 
  <div id="web_footer_marks" class="wm_6"></div> 
  <div id="web_footer_marks" class="wm_7"></div> 
  <div id="web_footer_marks" class="wm_8"></div>
  <div id="web_footer_marks" class="wm_9"></div>
</div>

    I think this is caused because of context. Create a closure inside the loop so the code executes straight away. There should be other ways to solve this too. 

     <script> 
    $(function() {
        var number_menus = 9;
        for (i = 1; i <= number_menus; i++) {

    (function(i){

            var p1 = +i;
            $(".wm_" + i).show().css("background-image", "url(imagenes/footer/m/" + i + ".png)").mouseover(function() {
                $(this).css("background-image", "url(imagenes/footer/m/" + i + "_down.png)");
                alert("this_down.png");
            }).mouseout(function() {
                $(this).css("background-image", "url(imagenes/footer/m/" + i + ".png)");
            });

    })(i);

        }
    });​
</script>
