Question

我想要从隐藏字段中删除“^”分割的一组特定值我在隐藏的领域中投入了价值。现在我想要删除特定值集，即

HIDDEN FIELD VALUE = 1 | 1 | 1 | 1 ^ 2 | 2 | 2 | 2 ^ 3 | 3 | 3 | 3

DROP DOWN =
INDEX | VALUE | TEXT
  0 | 1 | 1
  1 | 2 | 2
  2 | 3 | 3

想要删除= ^ 2 | 2 | 2 | 2 WITH DROPDOWN VALUE 2;

这是我的代码，显示我如何将值放在隐藏字段

中

function putinactions()
{

    var hiddenfield = document.getElementById("hdfActions");
    var ActList= document.getElementById("Actionlist");

     var attdt= document.getElementById("txtAttOn");
     var depen= document.getElementById("ddlDepend");
     var tattby= document.getElementById("txtAttendedBy");
     var dattby= document.getElementById("ddlAttendedBy");
     var dpriority= document.getElementById("ddlPriority");
     var taction= document.getElementById("txtAction");
     var dstatus= document.getElementById("ddlStatus");
     var tacdt= document.getElementById("txtACDt");
    if(depen.value==9)
    {
       tattby.value = "0";
    }

      if(depen.value!=9)
    {
       dattby.value = "0";
    }

    if(hiddenfield.value=="")
        {
            hiddenfield.value=
                        attdt.value+"|"+ 
                        depen.value+"|"+
                        tattby.value+"|"+
                        dattby.value+"|"+
                        dpriority.value+"|"+
                        taction.value+"|"+
                       dstatus.value+"|"+
                       tacdt.value;
        }

   else
           {

            hiddenfield.value=hiddenfield.value+"^"+
                        attdt.value+"|"+ 
                        depen.value+"|"+
                        tattby.value+"|"+
                        dattby.value+"|"+
                        dpriority.value+"|"+
                        taction.value+"|"+
                       dstatus.value+"|"+
                       tacdt.value;
           }

            var optn = document.createElement("OPTION"); 
            optn.text=attdt.value+"~~"+taction.value.substring(0,20)+"...";
            optn.value=taction.value;
            ActList.options.add(optn);
        attdt.value="";
        depen.value="";

          taction.value="";
          tacdt.value="";
}
