I'm creating a site where I don't want anything to be done via custom javascript/jquery code at all, and I'm not sure it's going to be possible so need some advice.
The things that I want to be able to do are:
Load a JQuery (or Jquery style) dialog box containing a partial view.
Have a button that will select the "SelectedValue" from a dropdown list and render a partial view. (e.g. select a user from a dropdown and then click a button to add them to a list)
Append a partial view to an existing div.
I'm sure that all the above can be done using custom javascript, but what I want to is to use the standard Ajax and Html helpers that come with MVC3.
Main reason is that I've been struggling to get to grips with jQuery, but I also thought it would be nice to see if it can all be done without having to add a new script to the site.
As always, any help is greatly appreciated (even if it's just pointing me to articles).
The standard Ajax and Html helpers that come with MVC3 are for handling server-side stuff. Even the #Html.ValidationMessageFor helper usually uses their unobtrusive validation lib for jQuery validate.
Keep trying at jQuery, you'll get it. There is a reason it is so popular!
Update
I believe you can do #3 using #Ajax.ActionLink, but don't think you can do 1 or 2 out of the box with the Ajax html helper.
It seems that you can use the Ajax.BeginForm method to do this.
There are issues with the fact that it has been in a separate form as I can't nest the forms though.

What is the best way to place 2 identical forms on the same page, but use the same form action and fields for each form? How can I keep response messages in the respective form area from which the data was submitted?
I'd have one form in the footer of my site, and one form in a popup on the home page of my site. I'm using a hidden div and Magnific to open the popup containing the same code from the form that is located at the footer. Essentially, both form do the same thing, and utilize the same form action.
I do not have access to the form action, or the code in the form action page.
Currently, the forms existing on the same "page" are no problem, but when I submit an email on one form, the errors and success messages show up on both the popup form as well as in the footer form.
I've read that this may be possible to do with ajax, but for completeness sake, I want to make sure that I'm building that I'm doing what I can with the form html, before moving on to studying ajax for this.
Sadly there is no nice html/liquid solution for this.
The only way is to use cookies in order to save information which form was submitted and show the error message only for that form instead of the two ones.
AJAX is not a good solution because of the Google Recaptch-a when you submit the form more than once, which is a real pain in the a** since there is no way to disable it and the form will fail if you try to submit it with ajax.
The easiest solution is to use cookies, other option is to rely on an APP for this, but it may be an overkill for this.
Forms in Shopify are... how to put it nicely... dumb... basic... not developer friendly or just not made to be tweaked in any sort of way ( excluding the front-end ).
I am fairly new to .NET and MVC3 - and even Ajax and Json, and am working on an MVC3 (razor) application, using jqGrid, and so far it is immense(jqgrid that is!) and has dealt with everything I have thrown at it.
However, I have One Outstanding peice of functionality that I do not know How to accomplish.
Within the Edit form of a Row, I have Placed a Custom button called 'Reset Password'. I need the Onclick Event to call a piece of functionality in my Controller to go through some logic, generate a Password, and Return the new Password to the Screen.
Can anyone tell me How can I achieve this?
May thanks in Advance.
You can return a partial view result or json data from the action.
See the partial view approach here
Does anyone know of any bugs or other insight to explain why when using MVC4 with jquery mobile, any form that is created using Ajax.BeginForm results in the form being submitted twice to the controller.
I had originally thought that since I am using the js bundling that the same js file might have been being included twice and might be triggering on form submit, however thats not the case, my list of js files are:
jquery-1.6.4.js
jquery-ui.1.8.11.js
jquery.mobile-1.1.0.js
jquery.unobtrusive-ajax.js
jquery.validate.js
knockout-2.0.0.js
MicrosoftAjax.js
MicrosoftMvcAjax.js
MicrosoftMvcValidation.js
Modernizr.js
Within the project Ajax is fully enabled for everything i.e. i'm not disabling anything through mobileinit.
I have not posted any form code because it literally happens with every form - a form with one field and a submit button will cause the submission twice - but only where Ajax.BeginForm is being used.
Html.BeginForm doesn't exhibit any of these problems.
I've been stuck on this for a few days now so any help would be greatly appreciated
jQuery Mobile by default hi-jacks any form submission and performs its own AJAX request. To stop this behavior you can place the data-ajax="false" attribute on any <form> tag. Also make sure to stop the regular behavior of the form so it doesn't submit normally, something like:
$('#my-form').on('submit', false);
Docs: http://jquerymobile.com/demos/1.1.0/docs/forms/forms-sample.html
You could also just use the built-in jQuery Mobile AJAX rather than including extra JS for it. Which would only require you to make the action attributes of the forms to the server-side file to which they posts.
I'm using microsoft ajax and ajax.beginform.
It's working great for model binding my partial view, but I need to conditionally disable some of the buttons in my form itself depending on what comes back from the server.
How can I go about this without using JQuery?
Have you thought instead about using two separate views instead, and have your conditional logic in your controller determine which view to display.
For 90% of my site the standard MVC annotation with client script method is working a treat. But I have a form on the site that is quite complicated with multiple instances of dynamic form content dependant on answers to questions etc.
If I have the unobtrusive script included on the page, it's capturing the form submit and not allowing my custom jquery validate to validate the form.
I don't really want to refactor the site to have a seperate layout to remove the script when it's not needed. I wondered if there was an easy way to give control back to my custom validate script.
Any help would be great.
In your view you can disable client side validation like this
Html.ViewContext.ClientValidationEnabled = false
