    I’m trying to get the “use strict”; directive to work, and having a bit of trouble. In the following file FireFox 9 will (correctly) detect that someVar hasn’t been declared on line 3, but fails to detect that theVar hasn’t been declared on line 19. I’m stumped as to why this would be the case.”use strict”; // this will cause the browser to check for errors more aggresivelysomeVar = 10; // this DOES get caught // LINE 3// debugger; // this will cause FireBug to open at the bottom of the page/w

    I am using jquery on my html page and want to have an onchange event on a collection_select. If I add <%= javascript_include_tag :defaults %> then my jquery code does not work.

    I have a page with an iframe. In the iframe there’s a submit button. When I click the submit button I want the parent window to be updated. This is what I have done so far, and it works (the javascript is located in the parent window):var myFrame = $(‘iframe’); myFrame.load(function() { myFrame.contents().find(‘#publish’).click(function() {myFrame.load(function() {location.reload();});}); });The code works. But I find the reload of the iframe unnecessary. Is there a better way to detect when “su

When a menu in navbar is clicked the jQuery load function is triggered and the relevant content is loaded into the main page.It’s working fine, however I added an hash to the URL for whenever a particular content is loaded , so that users can go directly into viewing relevant content when they type or paste the url with the hash. This works fine in my local host but not on remote host I wonder What’s the problem.if

    At my company we use MVC.NET and Entity Framework to perform a SQL connection. I was wondering if there is a way to create a custom attribute on a class that will create warnings if the return type of a method is not IEnumberable? The idea is to avoid the developers defaulting to a collection making the function less generic.

    I am working on MVC3. not sure whether its the right question but it keeps on bothering me always.I have a generic model used by multiple views. If i make any changes to the model variables for example name change it does not reflect in any of the views nor does it throw any compile time errors. The errors are thrown only at run time. This can cause a serious issue if model changes are not checked for in each view manually.Is there any way to overcome this manual changes in the view?

    At work we have about 30 legacy sites which run from a common set of code, currently these sites are in cold fusion. For this common code we have one project, then in IIS we set up a virtual directory to include the common code into each site. This works great, as changes to core logic can be made in one place, and its replicated through all the sites. And as all of our sites are hosted on the same servers, we can also just deploy the common code and all the live sites are updated, we don’t need

I used a few tools to do so.The project appeared to successfully convert, but now it fails to compile. Specifically, it appears that there is a problem with System.Web.HttpContextBas

    I’m using the jQuery Validate plugin and what I’m trying to do should be relatively easy, but I can’t get it to work. I’ve got an input field that is not a mandatory/required field. If nothing is entered into the field I don’t want to run any form of validation on the field. If the form field changes and contains any input I want to validate it against, for example, numbers only, but if the field is blank, remove / don’t validate.I tried doing something like this:valForm(‘excessFrm’);var vou = $
