我想动态创建div,然后设置div的样式

[u010492376]

function creareXy() {
xml = createXml();
xml.open("get", "jsWifi.ashx?action=clickWifi", true);
xml.setRequestHeader("If-Modified-Since", "0");
xml.onreadystatechange = function () {
if (xml.readyState == 4) {
if (xml.status == 200) {
var msg = xml.responseText;
var json = eval("(" + msg + ")");
for (var i = 0; i < json.length; i++) {
var locaX = json[i].LocationX;
var locaY = json[i].LocationY;
alert(locaX);
//要查的是Select_Data
var dataTime = json[i].DataTime;
var phyValue = json[i].PhysicsValues;
var EqpName = json[i].EquipmentName;
//alert(EqpName);
var bobyDiv = document.createElement("div");//我这样创建层哪里错了，
bobyDiv.style.position = "absolute";
bobyDiv.style.width = "20px";
bobyDiv.style.height = "20px";
bobyDiv.style.zindex = 1;
bobyDiv.style.top = locaY
bobyDiv.style.left = locaX;

}
}
}
}
xml.send(null);
}

[娃都会打酱油了]

为什么要自己写这个呢？？ jq多好 $.ajax({success:function(data){ $(body).append('<div></div>'); }})

我是要从数据库中读取xy 轴的值，绘制一个层，
