I am playing with Jquery Mobile along with Backbone. Have some scenario to populate the dropdown(select) when one of the radio (option) is selected.
View and markup can be viewed from here [partial code][1]. I am able to populate the dropdown on radio button selection changed event.
Now I like to know how to set these values on page load for the radio and select. Any guidance would be appreciated.

This is the form I am working with:
It shows a basic Delphi form with a DB Grid on top with a panel underneath. The panel below contains two CheckListBox's and one radiogroup. Each CheckListBox contains three check boxes and the radiogroup consists of two radio buttons. There is also a button on the right of the panel with the text "Filter" on it.
Question: How can I select the check boxes and one of the radio buttons and then click the button to make the table filter according to the selection?
I have a website where I want users to be able to select what type of user they are during the registration process.
Specifically, the implementation I want is to have two buttons on the signup page, one called "Seller" and one called "Buyer".
The user should be able to select only one button and once clicked, it should stay highlighted (I know this is just jquery so not the issue).
The selection should be stored in a column in my users model called :type.
It seems pretty straightforward, but the "f.select" form method seems to only implement a dropdown menu, so I am wondering how I can achieve this implementation of two buttons.
Since you're already going to use jQuery, you could add a hidden field for type, create 2 links and style them as buttons, and use jQuery to update the value of type when a user clicks one of the "buttons".
I want to create a dynamic datatable using Primefaces that reflects user's choice. The user can choose one of the two radio buttons and then the datatable will be shown to the user.
The only difference between two radio buttons is that choosing the second one the datatable will contain an additional column.
Is it possible to create such datatable, using Primefaces and JSF?
Easiest solution would be to set rendered attribute of column depending on radio button selected.
...
<h:column rendered="#{myBean.radioValue}">
...
radio button 1 -> myBean.radioValue=false
radio button 2 -> myBean.radioValue=true
How to create a Combobox having Multiselect Capability using Jquery?
Does JQuery Combobox has this functionality or Property?
if it helps, take a look http://ivaynberg.github.io/select2/ for multi select values
Edited : I found one more link it's really great http://tameraydin.github.io/jquery-easyselect/
Combobox displays the selected value when its list of options is collapsed. You may want to use multiple selection list.
to use multiple select in combobox you will have to create your own user control using checked listbox, textbox and a button.
and on click of button just make checked list box visible and let the user select items from that checkedListBox and as user select items on it you take those values and concatenate it in textbox with comma seperated. and then again on click on button hide that list box.
as it is on : http://9perhour.co.uk/
which is asking for select technology

I have 2 radio button with values New & Existing. If user chooses New, then I show a textbox on the form and if Existing a dropdown and textbox is hidden. The question is , does the hide/show of the textbox/dropdownlist have to be written in the View or the Controller class? Also when I choose the selection my whole form is posting back and hence all validation error msgs are being shown which should not be shown nless the save button is clicked, how do I a partial postback without full form submission? Any code snippets or urls would be benificial in this respect.

Just show/hide with jQuery that.

Perform 'partial postbacks' through javascript.
Post form to save action only once when it's ready (when Save button is clicked).

If I understand you correctly, the answer is the hiding and showing of controls should be done on the view as it's display specific.
If you use javascript to show and hide the controls then because it's on the client side you would not have to postback the form, and could do server side validation when the save button is clicked.
jQuery is very good: Jquery Website
Hope that helps?
