jQuery在foreach循环内 [英] Jquery inside foreach loop

问题描述

我在foreach循环中有此jquery代码.基本上，变量$ perf在每个循环中都会获得一个新值.如何使用jquery在每个循环中显示不同的$ perf值?有可能吗?

I have this jquery code in a foreach loop. Basicaly the variable $perf gets a new value with every loop. How can I use jquery to display the different $perf value with each loop? Is it possible?

    foreach ($perfs as $perf):

    <script type="text/javascript">

    $(document).ready(function(){

    var performerName = $(".transparency").data('title'); 

    var divcontent = $(".transparency").html();

    if ( divcontent == '&nbsp;' ){

    $(".transparency").html(''+performerName+''); 

    }

    });

    </script>

   <div class="transparency" data-title="<? echo $perf; ?>">&nbsp;</div>

   endforeach;

推荐答案

您应该这样做:

<?
foreach ($perfs as $perf):
?>
    <script type="text/javascript">
    $(document).ready(function(){
       var $perf = "<? echo $perf; ?>"; //Get from php
       alert($perf); //Show it
       //Here goes the rest of your script
       var performerName = $(".transparency").data('title'); 
       var divcontent = $(".transparency").html();
       if ( divcontent == '&nbsp;' ){
         $(".transparency").html(performerName); 
       }
    });
    </script>

   <div class="transparency" data-title="<? echo $perf; ?>">&nbsp;</div>
<?
   endforeach;
?>

就是这样.可以.

(我试图至少尽可能地修改您的代码，因为我不知道是否可以删除部件)

(I tried to modify your code at least as possible, cause I don't know if I can remove parts)

PS:会有更多优雅"的解决方案，您想要一个吗?还是足够?
