asp.net ajax调用的时候防止按钮多次被点击
最近在做"激光" -- ccc的大工程。在用户提交异步请求的时候需要禁止button被多次点击。在这里找到了解决办法，记录一下。

我小小改动了一下，以适合"激光"的用处。我的代码如下：
<script type="text/javascript">
var pbControl = null;
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_beginRequest(BeginRequestHandler);
prm.add_endRequest(EndRequestHandler);
function BeginRequestHandler(sender, args) {
pbControl = args.get_postBackElement(); //get the control causing the postback
if (pbControl != null) {
if (pbControl.type == "submit") {
pbControl.value = "Saving...";
pbControl.disabled = true;
}
else {
pbControl.value = "Updating...";
pbControl.disabled = true;
}
}
}
function EndRequestHandler(sender, args) {
if (pbControl != null && pbControl.type == "submit") {
pbControl.disabled = false;
pbControl = null;
}
else {
pbControl.value = "";
pbControl.disabled = false;
pbControl = null;
}
}
</script>
var pbControl = null;
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_beginRequest(BeginRequestHandler);
prm.add_endRequest(EndRequestHandler);
function BeginRequestHandler(sender, args) {
pbControl = args.get_postBackElement(); //get the control causing the postback
if (pbControl != null) {
if (pbControl.type == "submit") {
pbControl.value = "Saving...";
pbControl.disabled = true;
}
else {
pbControl.value = "Updating...";
pbControl.disabled = true;
}
}
}
function EndRequestHandler(sender, args) {
if (pbControl != null && pbControl.type == "submit") {
pbControl.disabled = false;
pbControl = null;
}
else {
pbControl.value = "";
pbControl.disabled = false;
pbControl = null;
}
}
</script>
