Lets say i have two Questions, each with their respective checkboxes and a "Next->" button. I want to enable the "Next" button, once each Question has at least one checked checkbox. I have everything wrapped around a Form. Something like this
<form name="form_" novalidate>
<div="cont_1" >
<label>
<input type="checkbox" ng-model="data1.enabled" ng-required="!data1.enabled">
</label>
.
.
</div>
<div="cont_2" >
<label>
<input type="checkbox" ng-model="data5.enabled" ng-required="!data5.enabled">
</label>
.
.
</div>
<button ng-disabled="form_.$invalid">
</form>
The problem is that I have to select ALL checkboxes for the button to enable, i dont want that, what i want is for at least one from each question to be checked for the button to enable, it can be 1 & 1, 2 & 3 etc.. but not forcefully ALL of them. Ive used the ng-required with radiobutton before and it does work. Not the same with check boxes though. It seems the $invalid is checking for all of them to comply but that is not what i want.
Thanks in advance!!!
You should not be using ng-required for checkboxes, because required for checkbox means that it has to be selected to be valid. So if you have some checkbox in the form that is required then is has to be checked to have the form being valid.
It works differently for radio buttons. required on radio buttons enforces selection of atleast one value.
Check this
http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_checkbox_required
You should maintain for each question something like a flag which could be set on selecting an answer for that question, and enable the button if these flags for all the questions are set.
ng-required is not the way to go about it.
I agree with Nils - you are hoping to get something out of ng-required that it was not meant to do.
You need to either:
implement logic in some QuestionService that determines how many
checked answers constitutes an answered question, and drive your
view off of that logic, or
create a directive that monitors the checkboxes among its children.
For approach (1) I created a plunker: http://plnkr.co/edit/pON3PmS77oqqe0aj4Fsb

So, I want to display a set of radio buttons several places on a page. I want the state of the radio buttons to be linked, select option A on one form should select option A in all forms.
Sorry for not including examples.
Here is the idea:
<form id="serverForm">
<input type="radio" name="#(site.SiteID)" class="serverRadio" value="All"> All
<input type="radio" name="#(site.SiteID)" class="serverRadio" value="DS1"> DS1
<input type="radio" name="#(site.SiteID)" class="serverRadio" value="DS2"> DS2
<input type="radio" name="#(site.SiteID)" class="serverRadio" value="IS1"> IS1
</form>
This form is going to be created multiple times dynamically depending on the size of the loops its contained in. I want each of these forms to essentially act as duplicated. Clicking an option on one will update all.
Give a class attribute to all Radiobuttons.
Add an "on Click" event on that class.
Check the clicked radio button's value in the event
Compare the value with other radio buttons (in a loop for all radio buttons), if it's the same put the attribute "checked" on true
P.S.: Share your code next time so an easy code example can be provided or even the full solution.
1.)Make all the position 1 buttons of forms to same div and position 2 buttons to other same div and so on.
2.)Use any technique(like directing to any function or adding an onClick event in jquery) to check the changed class like:-
$(".class_to_be_checked").attr("checked","checked");
FIDDLE HERE: http://jsfiddle.net/TegFf/48/
I have a form with radio buttons (please Fiddle below) that should validate if:
you choose a radio button that has a dollar amount associated
you choose custom AND enter a value
My problem, I think, is that the Ng-Required I have put on an input field is not properly registering whether it is or is not required.
<input name="donation" type="radio" value="yes" ng-model="manual" required="false">
<input type="number" ng-model="donation" ng-required="manual === 'yes'">
http://jsfiddle.net/TegFf/49/
Couple of things:
First radio input has a different name.
Wrapping the manual amount inside a label together with the radio button prevents you from focusing the field.
An AngularJS form is not valid until all fields are valid, so it's easier if you add more debug code to see which field is actually invalid.
Your first radio button needs to have 'name="donation"' added to it. Another issue is that once variable manual is set to 'yes', it will always stay yes. You should either reduce the number of your variables, or set up a custom validation in a directive.
I need to use javascript to check all radio boxes with a certain ID on a page. The radio buttons all have different names, and are grouped by 3, one for approve, one for deny, one for review...
<input type=radio name='21' value='approved' id='approved' title='Approve'>
<input type=radio name='21' value='denied' id='denied' title='Deny'>
<input type=radio name='21' value='review' id='review' checked title='Do nothing right now'>
...and so on. I've searched on this site and all over the googles, not really finding a solution that works for me. I have another set of radio buttons on top of the page, that I want to use to control the others, so if I click the "approve" radio up top, all the approve radios are selected, deny does all the denied radio boxes on the page etc.
I am using an onclick on the top radio buttonset to fire a javascript function, but I've no idea what to tell the function to do. I assume that jquery would be able to do this nicely, but cannot seem to come up with the code to do so.
Try a click function on all radio and update the selection based on its value. See below,
// v--- Refined the selector as you want this to happen only when clicking on the
// controller radio options.
$('.controller:radio').click(function () {
$(':radio[value=' + this.value + ']')).prop('checked', true);
});
DEMO: http://jsfiddle.net/KvdNq/
What I would do is actually create the groups within separate DIVS. Then you can loop through all the radios within that particular div and dont need to care about what the IDS are for the respective Radio Buttons.
<div id="group1">
<input type="checkbox" value="group1"/> Check all in this group
<input type = "radio" value="xx" />
<input type="radio" value="yy" />
</div>
Now you can simply create a function that takes the value of the checkbox, then loops through the matching div, checking all the RADIO BUTTONS within it. Make sense?
Summary of problem statement: Radio button html on the browser does not display the checked attribute, but Firebug indicates that the radio's checked attribute is set as checked.
Tested on
Broswer: FF 3.6.18 and IE8
jQuery: 1.5
MVC3 (Razor)
Details
Using MVC3 (with Razor) I'm rendering the following radio buttons from the server. The desired functionality is that on checking one radio, the other should be unchecked and vice-versa. In other words, the user is allowed to only select one option - say val1 or val2.
<div id="myRadioList">
<div>
<input type="radio" value="val1" onclick="updateFunctionCalledHere(this)" name="myRadioName" id="myRadioName_val1" checked="checked">
</div>
<div>
<input type="radio" value="val2" onclick="updateFunctionCalledHere(this)" name="myRadioName" id="myRadioName_val2">
</div>
</div>
What I'm observing is that if the user toggles the radio selected, the newly selected radio (let's say myRadioName_val2) is shown to be checked using firebug but the html still reflects the other radio button as checked. Because of this, some other validations are failing.
I've tried literally removing all checked attributes of both the radio buttons and then just check the one that's clicked.
This is what I'm doing to set the currently clicked radio, that is not working:
$("#myRadioList > div > input[value='myRadioName_val2]').attr('checked', 'checked');
I'm simplifying my code to avoid posting unnecessary details.
The checked attribute in HTML is the default value.
The checked property in JavaScript refers to the current state of the radio button.
Generally, it's best to let the browser handle the checked state of radio buttons and checkboxes rather than setting it yourself, otherwise you run into these kinds of problems. It's safe to get the current state via prop("checked") as already suggested, or through .is(":checked").
You may also want to consider using syntax like $('#myRadioList').find('input[value="myRadioName_val2"]') or better yet, $('#myRadioName_val2'), as child selectors in jQuery can be rather slow, since they are read right to left.
You should use
$("#myRadioList > div > input[value=myRadioName_val2]").prop('checked', true);
Well, you do have a syntax error withing the jQuery selector. It should be:
$('#myRadioList > div > input[value="myRadioName_val2"]')
I have been doing some research on a good way to clear a jQuery form.
I have a couple of ideas but I want to know if someone has a better way.
I know about using reset, but sometimes it is necessary to set a field back to a particular value that may not be accomplished by reset. (ie. if a form starts with some pre-filled data and you want to clear it)
I have read some discussion here: Resetting a multi-stage form with jQuery
But I have another idea that I will post as an answer. Please let me know what you think and if you have a better solution.
More Information:
For example I have an address form. It has a couple of inputs, selects, radios, etc. along with a copy into new button and a clear button. By default I want to have this particular radio selected to option 1.
<div id = "AddressList">
<div class = "Address">
<input type="radio"/> --obviously with some options here
<button>copy into new</button>
</div>
</div>
The user selected option two and clicks copy into new. So I say something like on the click of the click of the copy into new:
$("#addressList").append($(this).closest("#Address").html());
In the second address the secon radio button is selected. The user selects the third radio button. At this point clicking the reset button would reset the input back to option two not option one.
My solution would be to add the attribute called clear.
Then say $([clear]).val($(this).atrr('clear'))
