I have a questionnaire with radio buttons and checkboxes which I want to grade. Almost all of them have this format:
<input type="radio" name="1" value="Да"
onclick="document.getElementById('pls').setAttribute('required', true)" required>Да
<input type="radio" name="1" value="Не"
onclick="document.getElementById('pls').removeAttribute('required')">Не </br>
I need both the name and value attributes to carry their current purpose, so I cannot use them.
Is there a way to still assign some point values to the different answers and get they summed client side. Then ill add them as a different column in a database. The problem is just having an attribute carry the value of the answer.
EDIT:
This is the full format of 2 questions:
<b>1.QUESTION?</b></br>
<input type="radio" name="1" value="Да" data-points="1" onclick="document.getElementById('pls').setAttribute('required', true)" required>Да
<input type="radio" name="1" value="Не" data-points="0" onclick="document.getElementById('pls').removeAttribute('required')">Не </br>
<input type="radio" name="1" value="Пропуснах да се огледам" onclick="document.getElementById('pls').removeAttribute('required')">Пропуснах да се огледам </br>
<i>COMENT?</i> </br>
<textarea name="edno" id="pls"></textarea></br>
</br>
<b>2.QUESTION?</b></br>
<input type="radio" name="2" value="Да" data-points="1" onclick="document.getElementById('2a').removeAttribute('required')" required>Да
<input type="radio" name="2" value="Не" data-points="0" onclick="document.getElementById('2a').setAttribute('required', true)">Не </br>
<i>COMMENT</i> </br>
<textarea id="2a" name="dve"></textarea></br></br>
Now I need when I have option one ДА checked to add 1 point and when НЕ is checked to add 0 points to the score. I hope this clears it.
Use data-attributes:
<input type="radio" name="1" value="Да" data-points="10" onclick="changePoints(this); document.getElementById('pls').setAttribute('required', true)" required>Да
<input type="radio" name="1" value="Не" data-points="5" onclick="changePoints(this); document.getElementById('pls').removeAttribute('required')">Не
So you can get them with javascript:
function changePoints(el)
{
var points = el.dataset.points;
alert(points);
}
Demo
Remember: For any kind of data you need to set in an element, use data- attributes. Is not nice to use any other default attribute for that.

A form with radio buttons. If "Existing" is checked, the "existingnumber" input will be enabled. It works fine during the selection process but does not work onload. On load the input "existingnumber" remains disabled even though it's "checked". This is problematic when the form is submitted, and fails error validation. I've tried appending .change() at the end, and creating a function which I called on document ready but that didn't work. I think I'm missing something. Perhaps I need to get the value first? I'm a bit of a jquery noob.
<input type="radio" name="officephone" value="New" id="officephonenew" >
<label for="officephonenew">New</label><br>
<input type="radio" name="officephone" value="Existing" id="officephoneexisting" checked>
<label for="officephoneexisting">Existing</label><br>
<input type="text" name="existingnumber" placeholder="555-555-1234" /><br>
<input type="radio" name="officephone" value="No" id="officephoneno">
<label for="officephoneno">Not required</label>
$('input:radio[name="officephone"]').change(function(){
$('input[name="existingnumber"]').prop("disabled",true);
if($(this).attr('value') == 'Existing') {
$('input[name="existingnumber"]').prop("disabled", false);
}
});

To make this work on load simply use filter() to retrieve the checked radio button and trigger() the change event on it.
Also note that you can simplify the logic by providing the boolean output of the condition to the disabled property and by using val().
$('input:radio[name="officephone"]').change(function() {
$('input[name="existingnumber"]').prop("disabled", $(this).val() != 'Existing');
}).filter(':checked').trigger('change');

<input type="radio" name="officephone" value="New" id="officephonenew" />
<label for="officephonenew">New</label><br />
<input type="radio" name="officephone" value="Existing" id="officephoneexisting" checked />
<label for="officephoneexisting">Existing</label><br />
<input type="text" name="existingnumber" placeholder="555-555-1234" disabled /><br />
<input type="radio" name="officephone" value="No" id="officephoneno" />
<label for="officephoneno">Not required</label>
I have two radio buttons. When I click on one, the other should become unchecked, and vice versa.
The code I've produced so far is not working:
<input type="radio" id="rbdemail" onclick="chekrbdclick()" checked="checked" />
<input type="radio" id="rbdsitelnk" onclick="chekrbdclick()" />
function chekrbdclick()
{
// How to manage here?
}
Simple, just use a 'name' property with the same value for both elements:
<html>
<body>
<form>
<input type="radio" name="size" value="small" checked> Small
<br>
<input type="radio" name="size" value="large"> Large
</form>
</body>
</html>
hope it helps
<form>
<label>
<input type="radio" name="size" value="small" checked> Small
</label>
<br>
<label>
<input type="radio" name="size" value="large"> Large
</label>
</form>
Give them a name attribute with common value like size, and it will work. For best practice, you can place your input tag inside a label tag, so that, even if your user clicks on the text beside the button (ie on "Small" or "Large"), the respective radio button gets selected.
The perfect answer is above answered ,but I wanna share you how it can work by javascript ,this is javascript work (not standard answer) ....
<input type="radio" id="rbdemail" onclick="chekrbdclick(0)" checked="checked" value="Small" />Small<br>
<input type="radio" id="rbdsitelnk" onclick="chekrbdclick(1)" value="Large" />Large
<script>
function chekrbdclick(n)
{
var small = document.getElementById('rbdemail');
var large = document.getElementById('rbdsitelnk');
if(n === 0){
small.checked = true;
large.checked = false;
}
else {
small.checked = false;
large.checked = true;
}
}
</script>
Below is my list of check boxes that is part of my php form. I need to write a script where only the last three check boxes must be checked for the form to be successfully submitted. I have looked at other similar questions but can't seem to find what I am truly looking for and I am having trouble to write the script.
<input type="checkbox" name="checkbox" value="Send email request">Would you like to receive weekly new via email?<br>
<input type="checkbox" name="checkbox" value="Agree to T&C">I agree to the Terms and Conditions<br>
<input type="checkbox" name="checkbox" value="No Criminal Records">I have no criminal associations<br>
<input type="checkbox" name="checkbox" value="No Business with any other company">I have no personal or business relationship with any other company<br>
You do not need to use any JavaScript.
Simply add a required attribute to the input elements.
<input type="checkbox" required="required" name="checkbox" value="Send email request">Would you like to receive weekly new via email?<br>
Take a look here for more info: http://www.the-art-of-web.com/html/html5-checkbox-required/
If you want a custom message or response, then you will need to use JavaScript to handle this.
Alternatively, you could use jQuery to check if it is indeed that the last 3 checkboxes or are checked (required) before submission. Consider this example:
<form method="POST" action="index.php" id="form">
<input type="checkbox" name="checkbox[]" value="Send email request">Would you like to receive weekly new via email?<br>
<input type="checkbox" name="checkbox[]" value="Agree to T&C">I agree to the Terms and Conditions<br>
<input type="checkbox" name="checkbox[]" value="No Criminal Records">I have no criminal associations<br>
<input type="checkbox" name="checkbox[]" value="No Business with any other company">I have no personal or business relationship with any other company<br>
<input type="submit" name="submit" />
</form>
<script src="jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#form').submit(function(e){
var count = 0;
var required_indeces = [1,2,3];
$('input[type=checkbox]').each(function(index, element){
if($.inArray(index, required_indeces) !== -1 && $(this).is(':checked')) {
count++;
}
});
if(count < 3) {
e.preventDefault();
}
});
});
</script>
The checkboxes need to have different names. Using the same name means you are only storing the value of the last checked box. Try one of these two options (for PHP):
<input type="checkbox" name="checkbox[]" value="Send email request">Would you like to receive weekly new via email?<br>
<input type="checkbox" name="checkbox[]" value="Agree to T&C">I agree to the Terms and Conditions<br>
<input type="checkbox" name="checkbox[]" value="No Criminal Records">I have no criminal associations<br>
<input type="checkbox" name="checkbox[]" value="No Business with any other company">I have no personal or business relationship with any other company<br>
Then, to check that the last three are checked:
if (!isset($_POST['checkbox'][1], $_POST['checkbox'][2], $_POST['checkbox'][3])) {
echo 'One of the last 3 NOT checked!';
}
OR:
<input type="checkbox" name="checkbox1" value="Send email request">Would you like to receive weekly new via email?<br>
<input type="checkbox" name="checkbox2" value="Agree to T&C">I agree to the Terms and Conditions<br>
<input type="checkbox" name="checkbox3" value="No Criminal Records">I have no criminal associations<br>
<input type="checkbox" name="checkbox4" value="No Business with any other company">I have no personal or business relationship with any other company<br>
Then:
if (!isset($_POST['checkbox2'], $_POST['checkbox3'], $_POST['checkbox4'])) {
echo 'One of the last 3 NOT checked!';
}
I have 3 different Radio Buttons in a page with the following code
<input type="radio" name"1" value="1">1</input>
<input type="radio" name"2" value="2">2</input>
<input type="radio" name"3" value="3">3</input>
How can I get the value of the selected radio button with different names ?
I tried
var option = $("input[type='radio'][name='1']:checked").val();
But giving Undefined. Any Idea's ?
You need to have them be the same name, otherwise they don't work as radios (they could all be selected), and you need your html to be valid:
<input type="radio" name="1" value="1">1
<input type="radio" name="1" value="2">2
<input type="radio" name="1" value="3">3
You're missing the = when assigning the name attribute.
<input type="radio" name="1" value="1" />
<!-- ^
Also, as others have pointed out in comments, input tags are self-closing. (although it does work even with invalid html)
Demo: http://jsfiddle.net/g7RT2/
You missed "=" sign after the "name" attribute, selector doesn't match name=1 condition: <input type="radio" name"1" value="1">1</input>
http://jsfiddle.net/gLgBj/
here is a working fiddle
http://jsfiddle.net/mW7mk/
your html is not well formated, the input is self closed and name="1" not name"1"
var options = $("input[type='radio'][name='1']:checked").val();
alert("test : " + options);
worked just fine with :
<label><input type="radio" name="1" value="1" checked="checked"/>1</label>
<label><input type="radio" name="2" value="2"/>2</label>
<label><input type="radio" name="3" value="3"/>3</label>
Is it possible to write a Javascript function to delete a drop down when it is blank?
<form name="myform" method="post" enctype="multipart/form-data" action="" id="myform">
<div>
<label id="question1">1) Draw recognizable shapes</label>
<br />
<input type="radio" value="Yes" id="question1_0" name="question1_0" />
Yes
<input type="radio" value="No" id="question1_1" name="question1_1" />
No
</div>
<div>
<label id="question2">2) Competently cut paper </label>
<br />
<input type="radio" value="Yes" id="question2_0" name="question2_0" />
Yes
<input type="radio" value="No" id="question2_1" name="question2_1" />
No
</div>
<div>
<label id="question3">3) Hold a pencil</label>
<br />
<input type="radio" value="Yes" id="question3_0" name="question3_0" />
Yes
<input type="radio" value="No" id="question3_1" name="question3_1" />
No
</div>
<input type="submit" value="Delete Drop Down" onclick="return checkanddelete"/>
</form>
If somebody does not select question 2 for example, it deletes question 2 label and the drop down.
Assuming you actually meant radio button groups (and not drop down lists) then firstly your HTML is incorrect, you need to set the name values of each group of radio buttons to be the same:
<input type="radio" value="Yes" id="question1_0" name="question1" /> Yes
<input type="radio" value="No" id="question1_1" name="question1" /> No
Then you need to loop through the list of radio buttons, if none in the group are selected then delete the parent div:
$('input[type=submit]').on('click', function() {
var radioArr = [];
$(':radio').each(function(){
var radName = this.name;
if($.inArray(radName, radioArr) < 0 && $(':radio[name='+radName+']:checked').length == 0)
{
radioArr.push(radName);
$(this).closest("div")
.remove();
}
});
return false; //to stop the form submitting for testing purposes
});
While you are there, you might want to add some <label for=""> tags around your text.
Here is a jsFiddle of the solution.
If your dropdown has an id of DropDown, and you are looking to hide the dropdon on submit click:
function checkanddelete()
{
if ( $('#question2_0.=:checked, #question2_1:checked').length )
$('#dropdown').hide() // Or $('#dropdown').remove() if you do not plan on showing it again.
return false; // if you plan on not submitting the form..
}
Optimization for use in a module for a page include adding appropriate ids and classes to the divs, which I'm assuming that in full code are there, but if you are planning on making UI adjustments I would advise against using a submit button in the mix..
I don't know, what do you mean under "dropdown menu", but here some info, that can help you.
You can set a class name for the all Objects, you want to delete. E.g.
HTML
<div>
<label class='question2' id="question2">2) Competently cut paper </label>
<br />
<input class='question2' type="radio" value="Yes" id="question2_0" name="question2_0" />
Yes
<input class='question2' type="radio" value="No" id="question2_1" name="question2_1" />
No
</div>
JS
$(".question2").remove();
As an another solution you can set an ID for the DIV Tag above all of this elements
<div id='block_to_remove'>
<label id="question2">2) Competently cut paper </label>
<br />
<input type="radio" value="Yes" id="question2_0" name="question2_0" />
Yes
<input type="radio" value="No" id="question2_1" name="question2_1" />
No
</div>
And then remove it in JS
$("#block_to_remove").remove();
