C#代码如下:
<TITLE> WebForm2 </TITLE>
<SCRIPT language=@#javascript@#>
function load(){
var drp2 = document.getElementById( "DropDownList2 ");
drp2.innerText= " ";
for(var i = 0;i <=drp2.options.length -1;i++){
drp2.remove(i);
}
var drp3 = document.getElementById( "DropDownList3 ");
for(var i = 0;i <=drp3.options.length -1;i++){
drp3.remove(i);
}
var xmlhttp = new ActiveXObject( "MSXML2.XMLHTTP ");
var oDoc = new ActiveXObject( "MSXML2.DOMDocument ");
var state=document.getElementById( "DropDownList1 ").value;
xmlhttp.open( "POST ", "webform1.aspx?id= "+state,false);
xmlhttp.send( " ");
var res=oDoc.loadXML(xmlhttp.responseText);
var naItems = oDoc.selectNodes( "//Market/Table/maName ");
var idItems = oDoc.selectNodes( "//Market/Table/maId ");
var item;
var id;
for (item = naItems.nextNode(),id=idItems.nextNode(); item&&id; item = naItems.nextNode(),id=idItems.nextNode()){
var nastr = item.nodeTypedValue;
var idstr = id.nodeTypedValue;
var newOption = document.createElement( "OPTION ");
newOption.text =nastr;
newOption.value = idstr;
drp2.options.add(newOption);
}
load2();
}
function load2(){
var drp2 = document.getElementById( "DropDownList3 ");
drp2.innerText= " ";
