jQuery load something based on whose class is “active”

问题:

I'm trying to use this with tabs that load content with ajax into a div. I can't get it to refresh on the interval. The top part does work, however.

<script type="text/javascript">  $(function rlAl() {     if ($("#xicon1").hasClass("active")) {     $("#actionlist").load("alcurrent.php");     }     else if ($("#xicon2").hasClass("active")) {     alert("icon2");     }     else if ($("#xicon3").hasClass("active")) {     alert("icon3");     }  });  $(function() {  setInterval(rlAl, 5000); }); </script>

回答1:

rlAl is undefined because it wasn't attached to the global scope, take it out of the $() you have it in in order to register it in the window namespace

function rlAl() {   if ($("#xicon1").hasClass("active")) {     $("#actionlist").load("alcurrent.php");   }   else if ($("#xicon2").hasClass("active")) {     alert("icon2");   }   else if ($("#xicon3").hasClass("active")) {     alert("icon3");   } } $(function() {   rlAl(); // so it executes straight away on DOM ready   setInterval(rlAl, 5000); });
