i have 2 <g:select> elements in my gsp and both allow multiple selection (listboxes). I wrote some javascript that adds the option clicked by the user to the other select.
I build an array of items in select2.
I also have a form, that consist of checkboxes and such and submit button.
My problem is that I need to send that javascript array along other form data ( when i press submit ), to the controller. I just can't figure out a way, to send it.
Select box will get serialized and send with other form components, if you set every option to "selected = true".

I have two dropdowns and a submit button on a rails form HAML page. I would like dropdown 2's content be populated dynamically based on dropdown 1 selection, and submit the form based on both of two dropdown's selected values.
I know how to do the submit part, but I'm a bit lost on the dynamic rendering for dropdowns. I can let dropdown 1 to call a controller method to update db (used by dropdown 2) and redirect to the form. This doesn't seem to perform well. Any suggestions on how to write the two dropdowns?
I'm using ExpressionEngine and SafeCracker along with Ajax (plugin: jquery.form.js - http://jquery.malsup.com/form/).
Best I can tell, SafeCracker will only allow for updating a single entry at a time. However, the UI / UX necessitates that a list be displayed. I've proof of concept'ed an entry by entry on-demand form. That is, click a particular edit link next to each entry and a snippet of jquery creates a form along with displaying a submit button. Click submit and that single entry updates. The inputs don't exist until the Update link is clicked
What I would prefer to do, if possible, is to create the non-form and form versions of each entry as the page is renbered and use some sort of toggle to display one or the other. Again, doable. Then, when I click the Edit link I'd add the necessary attributes to the input so that entry's form elements will be read but the other (display: none) elements for the other entries will be ignored. I'm thinking (out loud) that if I add the attr("name", some-value) that would work. That is, an input with no name will be ignored.
Yes, I can test this and I will. However, even if it works I'm not sure if it's a best practice and/or there's a more ideal way of accomplishing my ends. I'm here looking for validation and/or additional expertise and input.
Thanks in advance.
Just set disabled property to inputs and they will excluded from Form submission, whatever input fields are hidden or visible. Different jQuery methods, like submit() and serialize() follow specification of HTML 4 and exclude all disabled controls of a forms. So one way is to set
$('your_input').prop('disabled', true);
or ,
$('your_input').attr('disabled', 'disabled');
Check following link:
http://www.w3.org/TR/html401/interact/forms.html#successful-controls
Also, you may use a general button instead of a submit, as result you can handle click event on it and within that event you can make exclusion, validation, manipulation on values and what ever you like.
You can put a disabled attribute on them server side or set the property via jQuery:
$(".hidden input").prop("disabled", true);
Questions on Rails 3.0.7, and JQuery 1.5.1
Overview
I'm trying to do the following thing. I have a web page with a form on one side that lets me create a category, and a list of items on the other side, with a checkbox for each item. I would like to be able to check the check box, for each item, so that when I submit the form to create the category, the newly created category also creates a has_many through association with each item.
So the association part works almost, I can submit a list of checked checkboxes, and Rails creates the association on the backend if I send the list of checked items.
Problem:
Here's what doesn't work:
I am trying to submit the form via Ajax, so I wanted to bind an event handle to the rails.js 'ajax:beforeSend' event, so that it would scan through my list of checked checkboxes and at the checked ids to a hidden form field.
The problem is: I try to get a list of all the checked boxes, and add them to the hidden field when the user clicks the Submit button. Therefore, I figured I'd place the code to do so in the ajax:beforeSend event handler. What I "THINK" I'm noticing however, is that rails.js has somehow already processed the form fields, and constructed the HTTP query before this handler fires. I notice this through the following behavior:
Observed Behavior
1) I can reload a fresh page, click the button to submit the form, the alert boxes from my handler pop up saying that no boxes are checked, and the created category in my db has no associated items (CORRECT BEHAVIOR)
2) I then click 1 checkbox, the alert boxes pop up showing which boxes are checked (CORRECT). But then when I submit thee form, the category in the DB still has no associate items. And I can see through firebug and the server logs that and HTTP query was sent containing the old parameter list, not the newer one. (WRONG)
3) I then submit the same form again, changing nothing, and it shows me the correct number of items.
So I get the impression that the parameter construction is lagging. I hope this wasn't too long, an someone can help me figure out what is going on.
My Question:
What event do I need to bind to, so that the form gets submitted with the correct parameters? Or is there another way to go about it completely?
Thanks
Here's my code below.
Thanks,
$('#my_form')
/* Now we need to configure the checkboxes to create an association between
* the items, and the interaction that is being created. First we will bind a
* function to the click event, and if the box is then checked, we will add
* the item id to the list of interaction items. If it is unchecked, we will
* remove the item from the list of interaction items.
*/
.live('ajax:beforeSend', function(event){
// First get a list of all the checked Items
var checked_items = new Array();
$('#items input[type="checkbox"]:checked').each(function(){
checked_items.push(this.getAttribute('data-item-id'));
});
// Then add this list of items to the new_interaction form to be submitted
$('#interaction_new_items').val(checked_items);
alert(checked_items);
alert($('#interaction_new_items').val());
})
Bind to the click event on the submit button itself. The click event will be processed before your ajax beforeSend event.
$('#my_form .submit').click(function() {
// rest of your code here
});
A more flexible solution (say, in case you wanted to submit the form with something other than a click) would be to bind to the form's submit event.
$('#my_form').submit(function() {
// Tweak your form data here
})
I've got a list of products in an admin section of my website. I have the product title and then an icon for delete and an icon for set visible/set invisible. I have both icons wrapped in their own form elements so they fire seperate Actions. I now one to add some checkboxes to each line so I can do a bulk delete. Following this:
How to handle checkboxes in ASP.NET MVC forms?
I'd need to wrap the whole list in a form tag to return the checkbox values, but then I have the icons on each row wrapped in form tags. I'm not sure what to do or how to handle this so it all works. How can I maintain the line form tags but still get bulk update functionality?
It's probably going to require some JavaScript. I would create a form outside of the table with a hidden element. When a box is checked, update the hidden element to contain a comma-separated list of all the IDs for rows that have the checkboxes checked (this would be pretty straightforward with jQuery). When that form is submitted, parse the values of the hidden element and delete accordingly.
Another option is to wrap the whole thing in one form and make the names of the delete buttons unique, then check for that when the form is submitted. When doing a bulk delete, you'll have all the checkbox values submitted like normal and you'll know it's a bulk delete based on which button they pressed to submit the form.
I have 1 jsp form whcih take user detail and after clicking on submit button its store the data into DB and success message is displaying on the top of the GUI
but the problem is all the data iin the input boxes are not clear, data remain same in the input boxes
i m using struts2
can any body tell me how to clear all input boxes
Thanks

One option is to use a javascript to reset the form when the user clicks on submit. To do this, add the following javascript to your submit button (change 'form' to be the name of your form):
<s:submit value="Save" onclick="this.form.reset();" />
You could also use the Struts 2 JQuery Plugin which has a special tag for this purpose.
Better You set the the null value in model object in Action class of after store the data in DB and before return success
example if you have User object , you set user.setUserName(""); user.setPassword("")
