jquery get sender's form field value onClick

I have a page with lots of forms on it and every form has a dropdown and two buttons - ok and decline. I have an onclick that will trigger a function:
<input type="button" value="decline"
class="submit_button_wow"
onclick="submit_decision({{ x.id }},false,this)">
how do I figure the selected dropdown value from this form inside submit_decision?
{{x.id}}
is the id of decision that I fill out via template engine.

You're passing a reference to button to the submit_decision (the this). From it you can get parent form and, subsequently, the dropdown and its value.
Try something like this:
$(sender).parent("form").find("select").first().val()

Refrence the form from the button's form property. Then get the drop down list by its name.
function submit_decision(decision, myBool, button) {
var dropdown = button.form.myDropdown;
var selectedValue = $(dropdown).val();
}

JQuery, Show / hide a div based on dynamic radio buttons aka radio34 etc?

I'm producing a page dynamically and I have several sets of radio buttons. I need to use the record id in the id tag of the radio buttons. e.g.
<input type="radio" name="review_flag1797" id="review_flag1797"
value="n" checked="checked" />
How can I produce a single JQuery function to handle showing / hiding of my div. My radio buttons will have three values y, n and r. When the value is n I need to hide my div and show it for y and r.
To further complicate this, the radio of the radio button can set to a different value when its written.
EDIT
<div id="my_content1797">
content
</div>

I suggest you use a data-* attribute to store the ID of the set, just to make life a bit easier, maybe also give those radio buttons a common class:
<input ... class="someClass" ... data-id="1797" ... />
Then all you have to do is:
$('.someClass').change(function() {
if(this.checked) {
$('#my_content' + $(this).data('id')).toggle(this.value !== 'n');
}
});

I believe you want the jQuery toggle() method.
http://api.jquery.com/toggle/
onclick="$('#my_content<%=record_id%>').toggle(this.checked);"

You can hide the parent div using this statement
$("input[value='n']").parent().hide();
To show, give
$("input[value!='n']").parent().show();
You have to give this after the statements that add radio buttons dynamically, and also in the change handler of radio inputs. You can put these statements in a function and invoke it.
Also try http://api.jquery.com/closest/ if the div is not parent. This also selects parent.
$("input[value='n']").closest(...).hide();

Assign value to textbox

Hi i have a radio button(StarRating radiobutton using jquery) and a textbox. When i click on the star, i would like the radiobutton value to display to the textbox.
<input id="InsRating1" class="star" type="radio" name="InsRating" value="1" title="Worst"/>
<input id="InsRating2" class="star" type="radio" name="InsRating" value="2" title="Good"/>
I tried put the Onclick() in the but onClick() has never get fired.
Please advice how to get the value from my radiobutton to textbox. Thanks
I tried this below, but the value is "Undefined"
$(document).ready(function() {
$('#InsRating1').click(function() {
alert(this.value)
});
});
-------------Edit----------
I am using g_thom's answer below but come to this problem :
I have 3 set of stars with 3 textboxes. Each rating should show to only 1 textbox.
However whenever any star is clicked, it shows the value to all 3 textboxes instead of just specified one. Please advice. Thanks
<script type="text/javascript">
$(function() {
$('.star-rating').click(function() {
// assign the value of "total stars" to a textbox with an id of ratingText
$('#EvaluationInstructorRatingTextBox').val($('.star-rating-on').length);
});
$('.rating-cancel').click(function() {
// the value is '0' when the cancel button is clicked
$('#EvaluationInstructorRatingTextBox').val('0');
});
$('.star-rating').click(function() {
// assign the value of "total stars" to a textbox with an id of ratingText
$('#EvaluationMaterialRatingTextBox').val($('.star-rating-on').length);
});
$('.rating-cancel').click(function() {
// the value is '0' when the cancel button is clicked
$('#EvaluationMaterialRatingTextBox').val('0');
});
$('.star-rating').click(function() {
// assign the value of "total stars" to a textbox with an id of ratingText
$('#EvaluationValueRatingTextBox').val($('.star-rating-on').length);
});
$('.rating-cancel').click(function() {
// the value is '0' when the cancel button is clicked
$('#EvaluationValueRatingTextBox').val('0');
});
});

Since the inputs are converted to divs (with the 'rated stars' being assigned a different class), I think you'll want to count the number of divs with the .star-rating-on class and assign that value to the input, like this:
$('.star-rating').click(function() {
// assign the value of "total stars" to a textbox with an id of ratingText
$('#ratingText').val($('.star-rating-on').length);
});
Boring looking example - without the actual graphics/animations (just the HTML from the transformed inputs on plugin page - the value will always be 4): http://jsfiddle.net/bhf2d/
EDIT
The code above should work. I think you may be thinking that you need to apply your jQuery to the radio button, but that's not the case, since it is swapped out on page load with a div. Just in case you're not clear, I've added a live example using the code you provided in your question: Click here to see it.
EDIT 2
See an updated version here, matching the additional requirement to set multiple checkboxes. The textboxes have been renamed slightly (InsRatingText0 etc) to facilitate easily adding more items. The name convention InsRatingText[n] is set that way to match the div classes the plugin adds dynamically ('rater-0', 'rater-1', etc)

These <input> elements are not clicked, since they are hidden and replaced by <div> elements. You should use onChange() events instead.
Also, radio button do not use the property value, but checked.

Try something like this
$(function (){
$(".star").click(function(){
$("#textbox1").val($(this).val());
});
});
Basically, it is adding a handler for onclick to the eloement with class ="star" and then copying that value to the textbox.

$(".star").bind('click', function() {
$("#ratingValue").val($(this).text())
});
Seems like getting the val() on the checkbox didn't work, but using text() gives the value. Here is the example working: jsfiddle

Radio button on/off trigger works only one way

So this is the dumbest thing I've struggled with in awhile. I cannot get the state of a simple radio button set to toggle something on the page.
<label for="completeSw"><span>Completed?</span></label>
<input type="radio" id="completeSw" name="completeSw" value="1"/>Yes
<input type="radio" id="completeSw" name="completeSw" value="0" checked="checked"/>No<br/>
So you can see here an extremely simple yes/no radio button set to toggle an action. It needs to serve two purposes: to flag a yes/no value (1/0) in the POST data, and ideally trigger an action on the page using JS/jQuery. I'm having trouble with the latter.
The default state is "No"; if I click "Yes" I can retrieve an onchange or onclick event state and make something happen. However, this is a one-way switch; I cannot retrieve a state going back to the "No" selector once I've gone to "Yes". What I need to be able to do is show / hide an element on the page depending on what choice they've made in this radio set. If I click "Yes", I can trigger the action and see the page change. Once I click "No", however, it acts as if there was no state change and I cannot perform an action i.e. hide the element again.
I've tried variations on retrieving the "checked" state, the radio pair value, etc, e.g.
$("#completeSw").change(function(e){
alert( $(this).attr("checked") ); // only triggers when "Yes" is selected
});
Perhaps I should not be using a yes/no radio pair, but instead be using a single checkbox? Seems more user-friendly and elegant this way (radio buttons) to me.

IDs must be unique, so it will only ever find the first one on your page. Use a class instead.

Really, ID's must be unique, but you don't need 2 ID's. You'll only monitor changes in one radio. For example - "Yes" value
<label for="completeSw"><span>Completed?</span></label>
<input type="radio" id="completeSw" name="completeSw" value="1"/>Yes
<input type="radio" name="completeSw" value="0" checked="checked"/>No<br/>
And the you'll process the checked attribute of only this element. True - "Yes", False - "No"

Some browsers don't do anything when alert(message), message=null. And since an unchecked field has no checked-attribute, that could be the thing :).
Try:
alert('Checked: '+$(this).attr("checked"));

This is separate, but you're kinda using the label wrong also. The label is meant to extend the click area so someone could click on the word 'Yes' and the radio button will activate. Hopefully this helps you out a little.
<span>Completed?</span>
<input type="radio" id="completeSwYes" name="completeSw" value="1"/><label for="completeSwYes">Yes</label>
<input type="radio" id="completeSwNo" name="completeSw" value="0" checked="checked"/><label for="completeSwNo">No</label><br/>
<script type="text/javascript" charset="utf-8">
// If the radio button value is one then this evaluates to true.
var completeSW;
jQuery("input[type='radio'][name='completeSw']").change(function() {
completeSW = (jQuery(this).val() == 1);
alert("completeSW checked? " + completeSW);
});
</script>

"Pin" a class to the selected radio button?

I'm trying to add a class to the selected radio input
and then remove that class when another radio of the same type is selected
The radio buttons have the class 'radio_button' but i can't get
the class to change with the below code.
jQuery(".radio_button").livequery('click',function() {
$('input.radio_button :radio').focus(updateSelectedStyle);
$('input.radio_button :radio').blur(updateSelectedStyle);
$('input.radio_button :radio').change(updateSelectedStyle);
}
function updateSelectedStyle() {
$('input.radio_button :radio').removeClass('focused');
$('input.radio_button :radio:checked').addClass('focused');
}

Tre problem is caused by one extra space in your selectors.
Instead of:
$('input.radio_button :radio')
you wanted to write:
$('input.radio_button:radio')

You might also want to take advantage of jQuery's chainability to reduce the amount of work you're doing. (Rather than re-finding these buttons over and over again.) Something like this:
jQuery(".radio_button").livequery('click',function() {
$('input.radio_button:radio')
.focus(updateSelectedStyle)
.blur(updateSelectedStyle)
.change(updateSelectedStyle);
});
function updateSelectedStyle() {
$('input.radio_button:radio')
.removeClass('focused')
.filter(':checked').addClass('focused');
}

Give each radio button a unique ID
Pass the ID on the click
Remove the "focussed" class name for all the radio buttons with the same class
Add the "focussed" class to the radio button with the ID you passed

First, I agree with Rene Saarsoo's answer about the extra space.
Second, are you also trying to apply the style to the radio button label? You probably want to wrap the buttons and labels together somehow. For example:
<span class="radiowrapper"><input type="radio" name="system" value="1" class="radio_button"> 1</span>
<br>
<span class="radiowrapper"><input type="radio" name="system" value="2" class="radio_button"> 2</span>
Then get rid of the extra calls in your livequery call and move the code from updateSelectedStyle() function into your livequery call (I noticed issues with IE otherwise):
jQuery(".radio_button").livequery('click',function() {
$('input.radio_button:radio').parent(".radiowrapper").removeClass('focused');
$('input.radio_button:radio:checked').parent(".radiowrapper").addClass('focused');
});
