function get_a(){

} else {

}
}
}
XMLHttpReq.send(null);
}

function get_b(){
$("b").innerHTML = '<p class="tC"><br/><br/><br/><br/><br/>&nbsp;&nbsp;&nbsp;<img src="loading.gif" /></p>';

} else {
  document.getElementById("b").innerHTML = "加载失败！";
}
}
}
XMLHttpReq.send(null);
}

function get_c(){
$("c").innerHTML = '<p class="tC">&nbsp;<img src="loading.gif" /></p>';
createXMLHttpRequest();
XMLHttpReq.open("GET", "ceshi.asp?action=get_c",true);
XMLHttpReq.onreadystatechange= function(){
if(XMLHttpReq.readyState == 4){
if(XMLHttpReq.status == 200){
  document.getElementById("c").innerHTML = unescape(XMLHttpReq.responseText);
  document.getElementById("list_do").innerHTML = '<a href="#none" onclick="javascript:get_c();">刷新列表</a>';
} else {
  document.getElementById("c").innerHTML = "加载失败！";
}
}
}
XMLHttpReq.send(null);
}

function get_d(){
$("d").innerHTML = '<p class="tC">&nbsp;<img src="loading.gif" /></p>';
createXMLHttpRequest();
XMLHttpReq.open("GET", "ceshi.asp?action=get_d",true);
XMLHttpReq.onreadystatechange= function(){
if(XMLHttpReq.readyState == 4){
if(XMLHttpReq.status == 200){
  document.getElementById("d").innerHTML = unescape(XMLHttpReq.responseText);
  document.getElementById("list_do").innerHTML = '<a href="#none" onclick="javascript:get_d();">刷新列表</a>';
} else {
  document.getElementById("d").innerHTML = "加载失败！";
}
}
}
XMLHttpReq.send(null);
}


请问上面的a、b、c、d可以做个判断吗？如何做 请指教。

就只调用一个function get_a(这里是参数值) 主要是想减少代码！

------解决方案--------------------

JScript code

var cur;
function getIt(n){
cur = n;
$(n).innerHTML = '<p class="tC">&nbsp;<img src="loading.gif" /></p>';
createXMLHttpRequest();
XMLHttpReq.open("GET", "ceshi.asp?action=get_"+n,true);
XMLHttpReq.onreadystatechange= function(){
if(XMLHttpReq.readyState == 4){
if(XMLHttpReq.status == 200){
  document.getElementById(cur).innerHTML = unescape(XMLHttpReq.responseText);
  document.getElementById("list_do").innerHTML = '<a href="#none" onclick="javascript:getIt("' + cur + '");">刷新列表</a>';
} else {
  document.getElementById(cur).innerHTML = "加载失败！";
}
}
}
XMLHttpReq.send(null);
}
