Enable input field on radio button checked - javascript

I have 2 radio buttons and 2 input fields. I want to associate a radio button with an input field, so only the selected radio button's input field is enabled and others are disabled.
My html markup is:
<div>
<input type="radio" checked="checked" name="co" data-for="s" />
<input type="text" id="s" />
<br /><br />
<input type="radio" name="co" data-for="u"/>
<input type="text" id="u" disabled="disabled" />
</div>
So currently the first radio button is checked, and its input field is enabled. How can I do this with a bit of jquery code?
EDIT
I tried this:
$("input[type=radio][name=co]").bind({
change: function () {
if ($(this).attr("checked") == "checked")
$("#" + $(this).attr("data-for")).removeAttr("disabled");
else
$("#" + $(this).attr("data-for")).attr("disabled", "disabled");
}
});

Try this - http://jsfiddle.net/DMasH/
$("input:radio").on("click", function() {
$("input:text").attr("disabled", true);
$(this).next("input").attr("disabled", false)
});

$("input[type='radio']").click(function() {
$("input[type='text']").attr("disabled", "disabled");
if ($(this).next().attr("disabled") == "disabled") $(this).next().removeAttr("disabled");
else $(this).next().attr("disabled", "disabled");
});
Disable all boxes, then enable only the next one.

Solution - http://jsfiddle.net/4uQqE/2/
$('input[data-for]').change(function() {
target = $('#'+$(this).data('for'));
$('input[type="text"]').attr('disabled','disabled');
if($(this).is(":checked")) {
target.removeAttr('disabled');
}});​

Add required to input of hidden div when radio is checked

What I'm trying to do is to set hidden div with inputs depended on checked radio input.
This is the logic:
If the first radio is checked the first div is shown, there I want to add hidden inputs with some values...
If the second radio is checked I want the input to be added with required..
And, it shouldn't be required if the 2nd radio isn't checked...
I've tried a few things over some time and got some effects but can't get it work as I want, Here is the code that i'm currently trying to work with, sorry but it's messed up and fails...
So Any help will be much appreciated...
/*
// this code is working but I messed the HTML while trying to get it work with the other code below...
$(document).ready(function() {
$("div.hiddendiv").hide();
check();
$("input[name$='name02']").change(check);
function check() {
var test = $("input[name$='name02']:checked").val();
$("div.hiddendiv").hide();
$("#" + test).show();
}
}
*/
// The code i'm trying to work with...
$(function() {
var radio = $("#closed");
var hidden = $("#hide");
hidden.hide();
checkbox.change(function() {
if (checkbox.is(':checked')) {
hidden.show();
//add required
$('#name02').prop('required', true);
} else {
hidden.hide();
//clear when hidden checked
$("#name02").val("");
//remove required
$('#name02').prop('required', false);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" id="closed" value="01"> Closed
<input type="radio" id="open" value="02"> Open
<div name="01" class="hiddendiv">
<input name="name01" type="hidden" value="code">
</div>
<div name="02" id="hide" class="hiddendiv">
<input name="name02" type="text" value="">
</div>
Here is the JSFiddle,
try this code
give same name of radio button so it will work as a group and
also set id of input tag as name02 so its use as a #name02 in jquery
so it will work
$(function() {
var radio = $("#closed");
var hidden = $("#hide");
hidden.hide();
$(this).click(function() {
if ($('#closed').is(':checked')) {
hidden.show();
$('#name02').prop('required', true);
} else {
hidden.hide();
//clear when hidden checked
$("#name02").val("");
//remove required
$('#name02').prop('required', false);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" name='btn' id="closed" value="01"> Closed
<input type="radio" name='btn' id="open" value="02"> Open
<div name="01" class="hiddendiv">
<input name="name01" type="hidden" value="code">
</div>
<div name="02" id="hide" class="hiddendiv">
<input name="name02" id="name02" type="text" value="">
</div>
Part of your problem is that you need to set the name attribute of your radio buttons to be the same value, otherwise the HTML won't know that they belong to the same group.
I've updated the JSfiddle here
https://jsfiddle.net/hba4d83k/2/
What i have done is add a change event handler to your the radio group and then did some conditional logic to show/hide the relevant inputs.

Jquery .val() function to check the value of radio buttons

Below is my logic to check the value of each of the radio buttons. I am using a part of their id's to get hold of the radio buttons. However, my code is always returning a value based on the value of my first radio button. I want it to return the value of each radio button. For example if radio button clicked is yes, then value returned should be 1. Else, 0. Any body who can update my code please.
$('.YesNoRadio').each(function() {
if ($('[id*="YesNo_RadioButtonList_"] input[type="radio"]:checked').val() == 1) {
//$('[id*="AddAttachment"]').trigger('click');
$('[id="upload"]').click();
}
});
Html:
//For yes radio button
<input id="_YesNo_RadioButtonList_0" type="radio" name="YesNo_RadioButtonList" value="1">
//For no
<input id="_YesNo_RadioButtonList_0" type="radio" name="YesNo_RadioButtonList" value="0">
Your selector is incorrect, Remove space from selector. When you use " " it indicates you are targeting child elements i.e. Descendant Selector (“ancestor descendant”)
if($('[id*="YesNo_RadioButtonList_"]:radio:checked').val() == 1)
$('[id="upload"]').click();
And, You don't need .each()
//For yes radio button
<input class="YesNoRadio" id="_YesNo_RadioButtonList_0" type="radio" name="YesNo_RadioButtonList" value="1">
//For no
<input class="YesNoRadio" id="_YesNo_RadioButtonList_0" type="radio" name="YesNo_RadioButtonList" value="0">
<script type="text/javascript">
$('.YesNoRadio').each(function() {
if ($(this).is(':checked')) {
alert($(this).val());
//code for yes radio button
$('[id="upload"]').click();
}else{
alert($(this).val());
//code for no radio button
}
});
</script>
A method that worked for me was setting the name in the html input tag the same for each radio button is your list, which you did:
<input id="_YesNo_RadioButtonList_0" type="radio" name="YesNo_RadioButtonList" value="1">
<input id="_YesNo_RadioButtonList_0" type="radio" name="YesNo_RadioButtonList" value="0">
then I would do this is my JS with JQuery.
var radioButtonValue = $("input[name='YesNo_RadioButtonList']:checked").val();
This should give you the value of your radio button. The value, in your case, is preset in you input tag.
Try this code
$('.YesNoRadio').each(function() {
if ($('[id*="YesNo_RadioButtonList_"] input[type="radio"]:checked').val() == 1) {
//$('[id*="AddAttachment"]').trigger('click');
console.log($(this).val());
$('[id="upload"]').click();
}
});

How to disable a button if no checked boxes are clicked

I have checkbox column in my data table and I want to hide a button if none of checked boxes clicked.[including pagination].
below is my code I used to get the values when clicking button,pls advice,
$('#button').click(function () {
var id = "";
var oTable = $("#userTable").dataTable();
$(".groupCheckBox:checked", oTable.fnGetNodes()).each(function () {
if (id != "") {
id = id + "," + $(this).val();
} else {
id = $(this).val();
}
});
});
You can add an event listener to all of your checkboxes. Whenever something changes, you check if all of them are un-checked => disable the button, else => enable the button.
$(".groupCheckBox").on('change', function(){
if($(".groupCheckBox:checked", oTable.fnGetNodes()).length == 0){
$('#merge_button').prop('disabled', true);
}else{
$('#merge_button').prop('disabled', false);
}
});
$('#merge_button') disabled by default and a change event listener to all $('.groupCheckBox') elements.. In the event handler check if any checkbox is checked to update the button property:
$('.groupCheckBox').on('change', function() {
$('#merge_button').prop('disabled', $('input.groupCheckBox:checkbox:checked').length === 0);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" class="groupCheckBox">
<input type="checkbox" class="groupCheckBox">
<input type="checkbox" class="groupCheckBox">
<input type="checkbox" class="groupCheckBox">
<input type="checkbox" class="groupCheckBox">
<input type="checkbox" class="groupCheckBox">
<input type="checkbox" class="groupCheckBox">
<input type="checkbox" class="groupCheckBox">
<hr>
<button id="merge_button" disabled>Merge</button>

Javascript to enable/disable radio buttons when text field is cleared or chars are present

I'm working on a little script that will disable a form field if certain radio button are ticked or if the input filed has characters to disable the radio buttons
So what I'm wanting my code to do is when the User enters the text field and adds at least one character of any type to disable the radio buttons and if that field is cleared to re-enable the radio buttons
For some reason when I'm doing either or, my "Enabled" alert keeps showing and the radio buttons aren't being disabled
to get the alert to pop, need to click outside of the input field, I would like this to be a mouseout if possible but I can work on that later
If the value is entered within the form directly, the radio buttons are disabled but I can't get them enabled once the filed is cleared
Steps:
Enter text in text field, if value isn't set in the form. Radio buttons stay disabled
Enter Value within the form, the text buttons stay disabled when the text field is cleared
Working Parts:
If radio btn "Yes" is ticked display "test" string and disable text field
If Radio btn "No" is ticked then enable text field
jQuery version in use: 1.9
Below is my JavaScript and below that is the HTML
Script:
$(function() {
var tlHeader = 'Test';
var f2 = $('#field_2').val();
// This function controls inpput box toggling on/off radio buttons
$( '#field_2' ).change(function() {
if(f2.length != 0) {
alert( "Disabled" )
$("input[name=toggle]").prop('disabled', true)
} else if(f2.length == 0) {
alert( "Enabled" )
$("input[name=toggle]").removeProp('disabled')
};
});
window.invalidate_input = function() {
// This function controls radio btn actions
if ($('input[name=toggle]:checked').val() == "Yes") {
$('#field_2').attr('disabled', 'disabled'),
$('#thgtLdr').html( tlHeader );
$('#thgtLdr').not("No").show();
} else if ($('input[name=toggle]:checked').val() == "No") {
$('#field_2').removeAttr('disabled'),
$('#thgtLdr').not("Yes").hide();
}
};
$("input[name=toggle]").change(invalidate_input);
invalidate_input();
});
</script>
HTML:
<body>
<div id=rdTest>
<div class="inputField">
<label>Focal Image:</label>
<input name="FocalImage" type="text" id="field_2" class='textbox' value="" />
</div> <!-- End input field -->
<div class="radioGroup">
<label>Test Page:</label>
<input type='radio' name='toggle' value='Yes' id="tglyes"/>Yes
<input type='radio' name='toggle' value='No' id="tglno"/>No
</div>
<div id="thgtLdr">
</div>
</div>
</body>
Your use case isnt entirely clear but I'll show you how to achieve the basic goal.
First, I would avoid the mouse events and use keyup with a timer so that my function is only called when the user stops typing and not after each typed letter. Then it's just a mater of checking the text and acting to enable or disable the elements. Here is an example:
var keyupDelay = (function(){
var timer = 0;
return function(callback, ms){
clearTimeout (timer);
timer = setTimeout(callback, ms);
};
})();
$('#field_2').keyup(function() {
var $this=$(this);
keyupDelay(function(){
var val=$this.val();
console.log(val);
if(val=='') $('#tglyes, #tglno').prop('disabled',true);
else $('#tglyes, #tglno').prop('disabled',false);
}, 400 ); // triggered after user stops typing for .4 seconds, adjust value as needed
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id=rdTest>
<div class="inputField">
<label>Focal Image:</label>
<input name="FocalImage" type="text" id="field_2" class='textbox' value="" />
</div>
<!-- End input field -->
<div class="radioGroup">
<label>Test Page:</label>
<input type='radio' name='toggle' value='Yes' id="tglyes" disabled="true"/>Yes
<input type='radio' name='toggle' value='No' id="tglno" disabled="true"/>No
</div>
<div id="thgtLdr">
</div>
</div>
Try this
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
<script>
$(document).ready(function(){
$(document).on('click','.choice',function(){
if($(this).val() == 'yes')
{
$('.textfield').prop('disabled',true);
$('#string').html('Test Welcome');
}
else
{
$('.textfield').prop('disabled',false);
$('#string').html('');
}
});
$(document).on('keyup','.textfield',function(){
if($(this).val().length > 0)
{
$('.choice').each(function()
{
if($(this).is(':checked'))
{
$(this).attr('checked',false);
}
$(this).prop('disabled',true);
});
}
else
{
$('.choice').prop('disabled',false);
}
});
});
</script>
<body>
<form>
<input type="text" class="textfield" placeholder="enter text"/>
Yes<input type="radio" name="choice" class="choice" value="yes" />
No<input type="radio" name="choice" class="choice" value="no" />
<p id="string" ></p>
</form>
</body>
You can simplify your code in many ways.
The keyup event will be triggered every time the user releases a key on the text field. Inside the callback, you can get the value of the text field with this.value. From experience, it is best to use .prop() method when toggling certain input-related attributes like disabled and checked. You can enable/disable these attributes using booleans.
// cache the elements to avoid having retrieve the same elements many times
var $textbox = $('#field_2'),
$radios = $('input[name=toggle]'),
$div = $('#thgtLdr');
// everytime user presses a key...
$textbox.on('keyup', function() {
// check if a value was entered or not
// if so, disabled the radio buttons; otherwise enable the radio buttons
$radios.prop('disabled', this.value);
});
// when radio buttons change...
$radios.on('change', function () {
// check if value is Yes or No
if (this.value === 'Yes') {
$textbox.prop('disabled', true);
$div.text(this.value);
} else {
$textbox.prop('disabled', false);
$div.empty();
}
});
<div id=rdTest>
<div class="inputField">
<label>Focal Image:</label>
<input name="FocalImage" type="text" id="field_2" class="textbox" value="">
</div>
<div class="radioGroup">
<label>Test Page:</label>
<input type="radio" name="toggle" value="Yes" id="tglyes">Yes
<input type="radio" name="toggle" value='No' id="tglno">No
</div>
<div id="thgtLdr"></div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script> // place code here </script>
Also, get into the habit of caching your jQuery objects.

Need Help To Uncheck Radio Button If Aleady Checked Using Jquery

i need help to uncheck or check same radio button if button already checked? I have jquery function which is used to enable or disabled other radio buttons if already checked now i want to add some function that use for check or uncheck same radio button?
(function ($) {
$(document).ready(function () {
$('input:radio').click(function(){
var $inputs = $('input:radio')
if($(this).is(':checked')){
$inputs.not(this).prop('disabled',true);
}else{
$inputs.prop('disabled',false);
}
})
});
})(jQuery);
<input type="radio" value="Test1" />Test1
<input type="radio" value="Test2" />Test2
<input type="radio" value="Test1" />Test1
<input type="radio" value="Test2" />Test2
Although it is too late to answer, it could help others
I tried this solution.
Works very well for me!
$("input[type='radio'].myClass").click(function(){
var $self = $(this);
if ($self.attr('checkstate') == 'true')
{
$self.prop('checked', false);
$self.each( function() {
$self.attr('checkstate', 'false');
})
}
else
{
$self.prop('checked', true);
$self.attr('checkstate', 'true');
$("input[type='radio'].myClass:not(:checked)").attr('checkstate', 'false');
}
})
Simply replace disabled with checked:
$input.prop("checked", false);
or for this element:
this.checked = false;
However, if you are looking for form element which can be checked and unchecked, maybe input type="checkbox" /> is what you need.
$inputs.filter(':checked').prop('checked', false);
I think you need checkbox instead of radio button to uncheck the checked :
<input class="checkDisable" type="checkbox" value="Test1" />Test1
<input class="checkDisable" type="checkbox" value="Test2" />Test2
<input class="checkDisable" type="checkbox" value="Test3" />Test3
<input class="checkDisable" type="checkbox" value="Test4" />Test4
(function ($) {
$(document).ready(function () {
$('input:checkbox.checkDisable').change(function(){
var $inputs = $('input:checkbox.checkDisable')
if($(this).is(':checked')){
$inputs.not(this).prop('disabled',true);
}else{
$inputs.prop('disabled',false);
$(this).prop('checked',false);
}
})
});
})(jQuery);
The answer of Pablo Araya is good, but ...
$self.prop('checked', true);
is superfluous here. The radio button already has a checked state for every click.
