javacript　有关问题

<script language="JavaScript" type="text/javascript">[color=#FF0000]var objDrp=document.getElementById("DropDownList1");var arr_result = new Array();for(i=0;i<objDrp.options.length;i++){    arr_result[i] = objDrp.options[i].value;      }[/color]if(document.createRange){ var range = document.createRange();}else var range = document.body.createTextRange(); if(range.findText){ while(range.findText("和尚")){  range.pasteHTML(range.text.fontcolor("#ff0000"));  range.collapse(true); }}else{  var s,n; s = window.getSelection(); while(window.find("和尚")){    var n = document.createElement("SPAN");  n.style.color="#ff0000"   s.getRangeAt(0).surroundContents(n); }}</script>

range.findText(objDrp.innerHTML)//ORrange.findText(objDrp.innerText)//ORrange.findText(objDrp.value)
