高手来看看,有什么办法能这样即时显示总价?
不用什么AJAX.
如果打勾就在总价里相加并显示??
在经典上没人回.

<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
<title> new page </title>
<script>
function a(obj){
if(obj.firstChild.checked){
document.all.heji.value=parseInt(document.all.heji.value)+parseInt(obj.lastChild.innerText);
}else{
document.all.heji.value=parseInt(document.all.heji.value)-parseInt(obj.lastChild.innerText);
}
}

<body>
<span> 订购价格 </span> <br>
<span onclick= "a(this) "> <input type=checkbox> <span> 199 </span> </span> <br>
<span onclick= "a(this) "> <input type=checkbox> <span> 299 </span> </span> <br>

onclick=\ "OnClick_Chk(obj)
然后用一个循环将选中的累加
for(var i=0;i <objs.length;i++) {
if(objs[i].checked) {
try {
money1 = objs[i].value;//前提是控件绑定的是价格
money1 = parseFloat(money1);
......... money1 = money1 + money1;
}
catch(e){} } }
lable.innerText = money1;
}我是这样做的，不是复选框绑定价格
