数组用法:
<script language="JavaScript">
function DoTitle(addTitle,addcon) {
var revisedTitle;
var currentTitle = PostPdf.Group.value;
var gTitle   = PostPdf.GroupName.value;
if(currentTitle=="")
  { revisedTitle = addTitle;
    contitle=addcon;}
      else
  {   var arr1=gTitle.split(",");
          var arr = currentTitle.split(","); //拆分出数组
          for (var i=0; i < arr.length; i++)
      {
           if( arr[i].indexOf(addTitle) >=0){
              if (i!=arr.length-1){
                  revisedTitle=eval

("currentTitle.replace(/("+arr[i]+"/,)/g,'')");
             contitle=eval

("gTitle.replace(/("+arr1[i]+"/,)/g,'')");}
else if

(arr.length==1)
{contitle="";
revisedTitle="";}
else
{
                  revisedTitle=eval

("currentTitle.replace(/(/,"+arr[i]+")/g,'')");
             contitle=eval

("gTitle.replace(/(/,"+arr1[i]+")/g,'')");}



PostPdf.Group.value=revisedTitle;


PostPdf.GroupName.value=contitle;

   return;}

               }
      revisedTitle = currentTitle+","+addTitle;
  contitle=gTitle+","+addcon;
     }

PostPdf.Group.value=revisedTitle;
PostPdf.GroupName.value=contitle;
PostPdf.Group.focus();
return;
}
</script>

<form action="" method="post" name="PostPdf">
<select name="OrgName" onChange="DoTitle(this.options

[this.selectedIndex].value,this.options[this.selectedIndex].innerText)">
<option value='单价一'>货品一</option>
<option value='单价二'>货品二</option>
<option value='单价三'>货品三</option>
<option value='单价四'>货品四</option>
<option value='单价五'>货品五</option>
</select><br>
<textarea name="GroupName" cols="50" rows="5" readonly="True"></textarea>

<input type="text" name="Group"  readonly="True" style="width:280;">
