Joomla: image src path?

Question

这个java脚本代码在Joomla中不起作用吗？如何更改图像标签中的源路径？

function changetxt(name){ 
  var arr = new Array("btn1","btn2","btn3","btn4");
  var pic = new Array("ban_txt.png","ban_txt1.png","ban_txt.png","ban_txt1.png");
  var s="";
   for(var i=0;i<arr.length;i++){
     if(arr[i]==name){
        document.getElementById(name).src="../../images/orange.png";
        document.getElementById(name).src="../../images/"+pic[i];       
     }
     else{
        document.getElementById(arr[i]).src="../images/grey.png";}
   }

定义站点url和管理url，并将其与图像src一起使用。这肯定对你有用。

function changetxt(name){
  
  var adminurl = "<?php echo JURI::base(); ?>";
  var siteurl = "<?php echo JURI::root(); ?>";
  
  var arr = new Array("btn1","btn2","btn3","btn4");
  var pic = new Array("ban_txt.png","ban_txt1.png","ban_txt.png","ban_txt1.png");
  var s="";
   for(var i=0;i`<`arr.length;i++){
     if(arr[i]==name){
        document.getElementById(name).src=adminurl+"images/orange.png";
        document.getElementById(name).src=adminurl+"images/"+pic[i];       
     }
     else{
        document.getElementById(arr[i]).src=siteurl+"images/grey.png";}
   }
