问题 I am using jquery.validate in MVC 2 with MicrosoftMvcJQueryValidation. I have data annotations on my model which is then being translated into jquery validators. I am using a modification to MicrosoftMvcJQueryValidation as outlined by Soe Tun to allow my error messages to appear in a validation summary instead of beside the controls. When the page loads, everything works as expected. The problem is that I am using ajax forms with replace mode to rewrite the form. When I do this, I lose all of

问题 I'm working on building a search engine in my application, and because I don't want to have a Querystring in my URL, I'm currently using Javascript to submit the searchTerms for me.

问题 I am trying to get my IIS 7.5 to impersonate the account of the user accessing a site through a browser. If I use... <identity impersonate="true" userName="mydomain\myusername" password="mypassword" /> it works just fine. However, if I use... <identity impersonate="true" /> It won't pick up the user. Am I missing some code? Or is this an IIS 7.5 configuration issue? 回答1: I posted a previous answer, but I think this one applies better Try to select if you are using a specific user or pass

问题 I am using a dropdown which displays several form fields after you choose something from the dropdown. I have bound the dropdown with jquery to detect a change, however, the box must 'lose focus' before the .change is triggered. Any way to fix this? $("#EmployeeSelected").change(function () { alert('hi'); }); 回答1: It doesn't appear to require losing focus, at least with an traditional change. If you are using another form of changing, ie keystrokes, you may want to consider binding additional

问题 I have an Azure application that works perfectly on every one of my colleagues machines. On mine, the web application works, but not the azure project, which runs on the local development fabric. I'm getting a 403 error, which causes a blank page in Chrome. The application_start method gets fired and sets up the routes, but the actual MVC controller never gets called. Again, this works perfect if I run the web application directly. If I use that same azure project and deploy it online, it

问题 I have setup some areas, but I'm not sure how to Redirect to them via the RedirectToAction method. There doesn't seem to be any Area parameter I can feed it. Thanks 回答1: You will need to use RedirectToRoute if you are trying to redirect to an ActionResult outside the current area.

问题 I use Html helpers to display model data in form fields, e.g. Html.TextBoxFor, Html.TextAreaFor. When the model values are null, I would expect the values should be empty in the form fields. They are displayed normally in Safari and Firefox, i.e. empty, but in IE, they are shown as "null" in a text field (see image below). Any clue how to fix this? Thanks. 回答1: Well, it turned out to be JavaScript's problem (with IE, that is). In the following statement, if value == null , IE would display
