JQuery $ .post在VS 2010实例中工作，但在IIS 7.5中部署时则不行

Question

I have checked the url in $.Post, it's fine. I have also checked the connectionstring. Everything works great in the entire website including $.ajax commands except one $.post command. I keep getting "error while saving record" message.

Code I have is that on a jquery dialog box's Save button:

var post = $.post(url,
                        $("#myview").serialize(),
                        function () {
                            thisDialog.dialog("close");
                        });
                        post.error(function (xhr, ajaxOptions, thrownError) {
            alert("Error while saving the record");

This works in local VS instance when I run in debug mode but it doesn't run when I deploy the website to IIS 7.5. Can someone please guide what the issue can be? All dlls are present, url is fine too

url is: Home/Start

[HttpPost]
    public ActionResult Start(StartModel model, FormCollection collection)
            {
                try
                {
                    Service.Create(model);
                    return RedirectToAction("List");
                }

this works in VS but not in IIS 7.5

I get error code 500

Stack trace shows error message: SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM

i am setting the date value using jquery date control. any guidance is appreciate.

Answer 1

Have you try to capture the http request via your navigator's developer tool ? do you see the request and what is the response from the server ?

Answer 2

Set customErrors mode to "off" (in your web.config) and then investigate response in firebug, you should see nice stack trace returned from the server. Just make sure that your catch block (which you didn't post) looks like:

try
{
// your code here
}
catch(Exception ex)
{
 throw;
}

(Make sure that you are not doing throw ex; because that way you will lose stack trace).

You can continue from there.

As a blind guess it might happen that: 1. Service.Create(model); fails (perhaps you don't have perimissions from that machine to access "Service", or 2. It might happen that you are posting too much data, so try increasing maxRequest length in

<configuration>
    <system.web>
        <httpRuntime maxRequestLength="102400" executionTimeout="1200" />
    </system.web>
</configuration>

It would be useful to know your stack trace, though.

Answer 3

Without changing anything in your current setup, it may just be an error in the date format. Instead of setting the date as 1/2/2011 through the calendar control, try setting it as 1/2/2011 12:00:00 PM

Or reset datepicker dateFormat (other formats here ):

.datepicker({
    dateFormat: 'mm/dd/yy'
});

Answer 4

Without more info I am just taking a shot in the dark here, but it may be that you're using a relative URL, for example /bob/fred , and the server has a different file structure to your local application.

Lets suppose that your app is in the following structure:

/bob/fred <- the directory you're accessing in the $.post call
/jim/index.aspx <- the page you're calling $.post in

And when you put it on the server the file structure, from the application root, is like this:

/site/bob/fred
/site/jim/index.aspx

When running the app through VS 2010 this would be correct. However on the server it would require a different URL.

The next step should be checking the $.post call using Firebug - see if you're getting a 404. If so, the above info should help. If not, please post some more code.
