在Receive()中执行PostUrl()函数，在执行PostUrl函数时，将contents(urls)函数作为PostUrl函的参数传入，作为回调函数使用，但contents()函数是带参数的，如何将参数一并传入呢？主要代码如下：
<script>
function Receive() {
var action = "Receive";
var URL = "/ControlUnit/Menu/sms_submit.ashx";
var finterid = 9702;
var ftrantype = 301;
var fuserid = 3;
var urls = "/ControlUnit/Menu/MessageShow.aspx";
PostUrl(URL, action, finterid, ftrantype, fuserid, fn(urls));
//说明，这里fn(urls)作为参数传入是有问题的，因为它已经被执行了，而不是作为参数传入。
}
var fn = function contents(urls) {
if (urls != "") {
var userAgent = navigator.userAgent.toLowerCase();
var is_moz = (navigator.product == 'Gecko') && userAgent.substr(userAgent.indexOf('firefox') + 8, 3);
if (is_moz) {
//window.opener.parent.frames['iframeright'].document.location.href = urls;
}
else {
var pWindow = window.dialogArguments;
//window.dialogArguments.top.iframeright.location.href = urls;
}
window.close();
}
};
function PostUrl(URL, action, finterid, ftantypeid, fuserid, fn) {
var datastr = "{'action':'" + action
+ "','FUserID':'" + fuserid
+ "','FInterID':'" + finterid
+ "','FTranType':'" + ftantypeid
+ "'}";
var datajson = eval("(" + datastr + ")");
//var datajson = datastr;
$.ajax({
type: "Post",
url: URL,
data: datajson,
//contentType: "application/json",
dataType: "Json",
success: function (data) {
fn(urls);
error: function (err) {
alert(err);
}
});
}

PostUrl(URL, action, finterid, ftrantype, fuserid, fn，urls);
function PostUrl(URL, action, finterid, ftantypeid, fuserid, fn，urls) {
fn(urls)；
}
追问
urls也是作为单独的参数调用啊，那fn万一有很多个参数，不是得长长的一串了吗？有没有更好的办法啊
追答
PostUrl(URL, action, finterid, ftrantype, fuserid, fn，urls);
function PostUrl(URL, action, finterid, ftantypeid, fuserid, fn，urls) {
fn(urls)；
}
function fn(urls) {
alert(urls[0]);
alert(urls[1]);
...
alert(urls[n]);
}
function fn2(obj) {
alert(obj.prop1);
alert(obj.prop2);
...
alert(obj.propN);
}
