Proceed </button>
<input type="checkbox" name="checkbox3" value="yes">
By checking the box, I certify that have read the above disclaimers and agree to the rules. </input>
I have a checkbox and a button which will take me to next page. But, before I press the button the check box has to be ticked. If not, a label has to be displayed below the check box saying "accept to rules first". Help? Also, it would be great if i can highlight the checkbox to red if i click proceed without checking the checkbox. Can use javascript/jquery.
Try this it works
<form action="page.html">
<input type="checkbox" name="checkbox3" value="yes" required>
By checking the box, I certify that have read the above disclaimers and agree to the rules. </input>
<input type="submit" name ="submit"/>
</form>
To get you started:
<input id="checkboxAgree" type="checkbox" name="checkbox3" value="yes">
function checkAgree()
{
if (document.getElementbyId("checkboxAgree").getAttribute("checked") )//checkbox is checked
{
location.href = "page.html"; //load the next page.
}
else
{
Alert("You need to check the box before you can continue");
}
}
document.getElementById("proceed-button").addEventListener("click", checkAgree ,false);
addEventListener add an onclick event to the button. When clicked this executes the function checkAgree. When the checkbox has the attribute checked it is checked and the ifwill render true. location.href will load page.html.
Please delete the a that surrounds your button.

I already looked to similar questions but I still can't figure out how to fix it. On my webpage, I have some radio checkboxes which I would like to be required before going to the next question.
I have the following partial code:
<p>
Select the option that fits most to you<br><br>
<label>
<input type="radio" name="typesport" value="teamsport" >
I prefer a teamsport</label><br>
<label>
<input type="radio" name="typesport" value="individual">
I prefer an individual sport</label><br>
</p>

Can someone help me with getting a javascript code, that actually works for all radio-boxes, where you could only go to the next question when 1 radio-box is selected?
Cheers,
Max
Edit: What I've tried so far is the following:
I added "required" to the label, so it looked like this:
<label><input type="radio" name="typesport" value="teamsport" required> I prefer a teamsport</label><br>
I also added the ID to the button:

Furthermore, I used this JS script:
$(document).ready(function () {
$('#checkBtn').click(function() {
checked = $("input[type=radio]:checked").length;
if(!checked) {
alert("You must check at least one radio.");
return false;
}
});
});
However, this works fine for only one question. When I add this to all the other questions, I still can go to the following question when I click on the button Next question, and that is not what I want.
Radio boxes are fairly simple in nature in that you should always have at least one option in a radio-group checked by default. Preferably a N/A or 'Please Select' option.
In which case you would want to validate against the 'Please Select' option instead:
//when user clicks <a> element
$(".next-button").click(function() {
//group on radio button name and test if checked
if ($("input[name='typesport']:checked").val() == 'select') {
alert('Nothing is checked!');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>
Select the option that fits most to you<br><br>
<label><input type="radio" name="typesport" value="select" checked="true" > Please Select </label><br>
<label><input type="radio" name="typesport" value="teamsport" > I prefer a teamsport</label><br>
<label><input type="radio" name="typesport" value="individual"> I prefer an individual sport</label><br>
</p>

However
If you really want to validate that an option has been checked:
This should work:
//when user clicks <a> element
$(".next-button").click(function()
{
//group on radio button name and test if checked
if (!$("input[name='typesport']:checked").val()) {
alert('Nothing is checked!');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>
Select the option that fits most to you<br><br>
<label><input type="radio" name="typesport" value="teamsport" > I prefer a teamsport</label><br>
<label><input type="radio" name="typesport" value="individual"> I prefer an individual sport</label><br>

HTML5 supports the required attribute for radio buttons. I did some searching and HTML5: How to use the "required" attribute with a "radio" input field has more detailed information about this attribute.
You can set a radio button checked by default by using the checked attribute.
To check if it's checked or not, use this code :
if ($('input[name=typesport]').attr('value') != undefined) {
//execute code when it is checked
} else {
//execute code when it's not checked
}
For the input type text, if i add required attribute, my form won't submit and browser will focus on required field and alert will say please fill this field.
For the input type radio, if i add required attibute, my form won't submit but also it does not provide me any alert or focus on the radio which is unchecked.
If this is not an in-built functionality for HTML5, can i in some way create it and make it look like the same as it looks for text inputs so that style integrity is also preserved?
This code works well, if you not select radio, form will not submit. If you select one and enter text in textbox, form will submit.
<form>
<input type="radio" name="one" value="1" required>
<input type="radio" name="one" value="2" required>
<input type="radio" name="one" value="3" required>
<input type="text" name="two" required>
<button>Submit</button>

Checked on latest version of Google Chrome. May be you found a bug in your browser, try to update it.
Beside required radio button alerts work "perfectly fine" in Chrome...

it makes no sense at all to have an alert for a radio button, that's silly.
If you have a radio button:
there's absolutely no need to have only one radio button. → Use checkboxes.
there's absolutely no reason to have all radio buttons unchecked initially.
one must be checked by default - and it's your job to do so
logically there's no need to popup alerts like "This radio button is required" - therefore neither to set a required attribute to a radio button.
if you still don't understand why... well simple because radios are used as UI switch states. Only one can and must be checked. If you make them all initially unchecked - and a client unintentionally hits a radio - he's dead in the devil's loop, because once you enter the circle there's no way out. Therefore makes no sense to have all blanks in the first place. You cannot undo... (well, unless you have another silly checkbox or something that says "uncheck all radio buttons!" nonsense).
I have the following radio group.
<input type="radio" name="GROUP1" ng-checked="true" ng-model="group1" id="name1" value="one">
<input type="radio" name="GROUP1" ng-checked="false" ng-model="group1" id="name2" value="two">
<input type="radio" name="GROUP1" ng-checked="false" ng-model="group1" id="name3" value="three">
When a radio input is clicked, I want to be able to figure out if, before it was clicked, if it originally active or not.
For example, if I clicked on #name1, it would respond back true because it was already checked.
If I clicked on #name3, it would respond back false because #name1 was originally selected. But if I click on #name3 again, it would return back true.
Could anyone help me with this?
You can watch this code in your controller.
Now, whenever your model will be changed(in the ui or in the controller), this event will be raised.
$scope.$watch('group1', function (newValue, oldValue) {
//Place your code here ...
// You have access to the old and to the new Value
});
Just for your information, try to use at least watches as you can...
js:
if(this.checked){
alert("selected");
}else{
this.checked=true;
}
put this code in a function and call it in onClick event of radio button
I have four radio buttons. If I select the last radio button then one textbox is appearing. I handled this scenario by jquery. Now I want to validate in such a way that if user gets this textbox means if user checked the last radio button, then he should provide some text.But in my case, if I check any one of the radio button, its telling to provide some text. The code is like:
<input type="radio" name="bus_plan" id="smallBtn" value="1" />1
<input type="radio" name="bus_plan" id="smallBtn" value="2" />2
<input type="radio" name="bus_plan" id="smallBtn" value="3" />3
<input type="radio" name="bus_plan" id="smallBtn" value="Promotional" />
<span class="plantxt"><a style="cursor:pointer;" onclick="popup('popUpDiv')">Promotional Plan</a> (Please enter a promotional code)</span>
<div class="reg-line" id="pr_code_id" style="display:none">
<div class="reg-linea" align="left">Promotional Code: <sup>*</sup></div>
<input type="text" name="bus_prcode" id="bus_prcode" class="reg-line-input" value="Promotional Code" onblur="if(this.value=='') this.value='Promotional Code'" onClick="if(this.value==this.defaultValue) this.value='';" />
<br />
<div>
<div id="promotionalbox" style="display:none;font-size:13px;clear:both"></div>
</div>
</div>
<script type="text/javascript" src="js/jquery-1.7.2.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("input:radio[name=bus_plan]").click(function(){
var values = $(this).val();
if(values == 'Promotional'){
$('#pr_code_id').show();
}else{
$('#pr_code_id').hide();
}
});
});
</script>
and in js if I alert the value of document.getElementById('bus_prcode').value then always it is showing Promotional code, which is only for last radio button value.
Your code is a bit of a mess which is the root of this problem. Remember, one element per ID.
You may also find it helpful to look at jQuery .is(), for example:
$('input[value="Promotional"]').is(':checked')
n.b. I do not suggest the above, you should use identifiers in the appropriate way first.
Also worth noting that your code works fine for me using Chrome. See an example (which I have expanded for you) here: http://jsbin.com/ofujal/3/
You should not have an element with the same ID (your radio buttons). Also, you're getting the textbox by running document.getElementById('bus_prcode') and not the radio button. You should give a unique ID to your last radio button, e.g. btnPromotional, then bind click to it:
$("#btnPromotional").click(...)
Is it possible with Javascript to hide the checked-status of a radio button so that on a form submit the submit-request fails b/c of missing information?
For example: I have a group of radio buttons
<form action="?modul=daDaaaah&subModul=someCoolThingy" method="post">
<input type="radio" name="mygroup" id="nod_1" value="great" />
<input type="radio" name="mygroup" id="nod_2" value="greater" />
<input type="radio" name="mygroup" id="nod_3" value="awesome" />
<input type="radio" name="mygroup" id="nod_4" value="junk" />
<input type="radio" name="mygroup" id="nod_5" value="foo" />
<input type="submit" name="edit" value="Edit" />
</form>
Now I am checking the radio button with the id=1 and by submitting it (dunno whether I got the button correct, but I sorta guess it is correct) the server should get a request where it says mygroup=great (right?).
Now is there a way to have that radio button checked and hidden it at the same time?
I am asking b/c somehow a javascript I am using is supposedly hiding this status (everywhere but in IE) by somehow altering the DOM or what do I know and I can't seem to get the right request nor find the reason why or how it does it.
If I am being unclear, please say so.
EDIT: One javascript that has this effect can be found here http://www.frequency-decoder.com/demo/table-sort-revisited/js/paginate.js but others do so as well :(
EDIT: Changed ID-names. Still doesn't work.
One thing is you can not have ids that begin with a number. So your radio buttons should be something like rad1, rad2, etc.
If the radio has disabled="true" then the value will not be present in the request so you could check for that.
