I need to select a radio input with name and value in jquery
In this example how you select element with name SiblingSex and value female
<form action="">
<input type="radio" name="SiblingSex" value="male">Male<br>
<input type="radio" name="SiblingSex" value="female">Female
<input type="radio" name="ParentSex" value="male">Male<br>
<input type="radio" name="ParentSex" value="female">Female
</form>
i need some thing like
$('input[name="SiblingSex"]' /*GENDER SELECTOR */)
You can add another attribute selector with this:
$('input[name="SiblingSex"][value="female"]').val();
the above line would give you values every time whether it is checked or not.
so if you only want to have the value when it is checked too then add :checked
$('input[name="SiblingSex"][value="female"]:checked').val();
Just have a look on the Demo on my JS Fiddle Code
Shows the two scenario:
1) when you want the value without selecting radio button.
2) when you want value after selecting radio button.
or may be the thing that you want is here::

i have a group ooa radion buttons defined as so
<input type="radio" name="required[status]" id="status" value="1">Yes </label>
<input type="radio" name="required[status]" id="status_1" value="0"> No </label>
<input type="radio" name="required[status]" id="status_2" value="2">Maybe </label>
this is stores the value 0,1,2 in a field status in the db
later, i get the value from db as 1, how do i use jquery to check the appropriate radio button?
if you are trying to check the radio button element by its value you can you the jquery attribute selector.
click me
you can get the element by its value like this:
$('[value=VALUE_FROM_DB]').prop("checked", true);
Here is the html part:
<input class="demo" radio-value="yes" name="Radios" id="sample1" value="" type="radio">
<input class="demo" radio-value="yes" name="Radios" id="sample2" value="" type="radio">
<input class="demo" radio-value="yes" name="Radios" id="sample3" value="" type="radio">
<input class="demo" radio-value="yes" name="Radios" id="sample4" value="" type="radio">
How can I know which radio button the user is selected and how can I know the value of selected radio button.
I want to get the "radio-value" of the selected button. Because, I will be using value for json input..
How can I do that??
First of all, all of your radio buttons have the same id - this is illegal and can cause unexpected behavior. Provided this is fixed, you can do something like this:
var selectedValue = $("input.demo:checked").val();
and for radio-value:
var selectedRadioValue = $("input.demo:checked").attr("radio-value");
Use :selected with class selector to get the selected radio button. You should give unique ids to html elements. Also the value of all the radio button is empty string you may need to assign some values to them
$('.demo:selected').val();
$('.demo:selected').val(); // class is demo
This would do the trick!
But you need to remove the id that is similar among all the elements. You should change their value such as sample1, sample2 etc. Then you can get the value, and the id.
I'm setting up a table, where each row will contain several radio boxes. There are certain conditions for the radio boxes, for example:
If "Home" is checked, the "Text" radio box will be unchecked and "Voice" will be checked instead (ie. You can't text a home phone number). Similarly, when "Home" and "Voice" are checked, clicking "Text" will force "Home" to be unchecked and "Cell" will become checked.
I can get this working fine for one instance, with the use of .getElementById and the click function, but where I run into trouble is when things are scaled up. This table might have 20 or 30 rows, each of which containing a cell with these radio boxes.
I'm not great with jQuery, so I'm not sure how to make a more general version, so that each set of radio boxes are their own contained units, so to speak. I made a jsfiddle where you can see that only the first instance is working, likely because I am targeting the boxes using their id and you can't have two elements with the same id... help? Thanks!

Script
$( document ).ready(function() {
document.getElementById('contact-home').onclick = function () {
document.getElementById('format-voice').checked = true;
};
document.getElementById('format-text').onclick = function () {
document.getElementById('contact-cell').checked = true;
};
});
HTML
<form>
<input type="radio" name="contact" value="" id="contact-cell" />
<label for="contact-cell">Cell</label>
<input type="radio" name="contact" value="" id="contact-home" />
<label for="contact-home">Home</label>
<input type="radio" name="format" value="" id="format-voice" />
<label for="format-voice">Voice</label>
<input type="radio" name="format" value="" id="format-text" />
<label for="format-text">Text</label>
</form>
You are going to want to assign every radio box a descriptive class like 'text-radio' or 'home-radio'. Then when you need to change all of the Text radio boxes you do something like the following in jQuery:
$(".text-radio").attr('checked', 'checked');
I have an input field like below
<input class="d_o" type="radio" value="super" name="old_or_new" checked="checked"> Get this value actually</input><br/>
I have to get the value of the input field i.e., Get this value actually, so tried the below jquery code
console.log($('.d_o').text());
But i am surprised that its returning nothing, and its working when tried to get the value like $('.d_o').val()
So how to get the text value from the above input field using jquery am i missing anything ?
The entirety of your <input> element is
<input class="d_o" type="radio" value="super" name="old_or_new" checked="checked">
The text that's after it, and the invalid html </input> are completely different nodes in the DOM tree. So val returns the value "super" as expected, but there's no text for text to return.
The .text() method cannot be used on form inputs or scripts
http://api.jquery.com/text/
Although I am not sure what approach jQuery follows on this : One explanation can be the "Content Model" specification of each HTMLElement .
Content model
A normative description of what content must be included as children and descendants of the element.
For example :
For Input type : http://www.w3.org/TR/html5/forms.html#the-input-element
Content model:Empty.
However for Title Element this is defined as
Content model : Text
http://www.w3.org/TR/html5/document-metadata.html#the-title-element
Eager to see the validations on this postulate :)
<input class="d_o" type="radio" value="super" name="old_or_new" checked="checked"> Get this value actually</input><br/>
This is not the correct way to handle the <input> tag. You should use :checked and .val() instead:
$(document).ready(function(){
$('#hey').on('click', function(event){
alert($('.check:checked').val());
});
});
<h2>Select old or new</h2><br>
<b>Old</b>:<br>
<input type="radio" class="check" name="old_or_new" value="old"><br>
<br>
<b>New</b>:<br>
<input type="radio" class="check" name="old_or_new" value="new"><br>
<br>
<input type="button" id="hey">
Check the fiddle: http://jsfiddle.net/MLWCK/
<input type="radio" name="radiobutton" id="1_1 value="1. Жетоны" "/>
<select id="1_1" onchange="document.GetElementById(this.id).checked=true;">
How come when I change option of select, radio isn't checked?
Thanks for carefuly!
But there is something else wrong, because it does not work too:
<input type="radio" name="radiobutton" id="1_1" value="1. Жетоны" "/>
<select name="1_1" onchange="document.GetElementById(this.name).checked=true;">
Thanks to shashi!
There are two things wrong:
- Your input tag is invalid HTML - it's missing a closing double-quote on the id attribute's value, and you have an out-of-place double-quote at the end of the tag.
- It looks like you're trying to use the same id for both the input and select tag. You can't do that; their ids must be different.
Replace,
document.GetElementById(this.id) with document.getElementById(this.id);
https://developer.mozilla.org/en-US/docs/Web/API/document.getElementById
Element IDs must be unique in a page, however element names can be repeated. Also, form controls must have a name to be successful (i.e. be submitted to the server).
So you can fix the problem by using references to form controls (and fixing the markup):
<form>
<input type="radio" name="radiobutton" id="1_1" value="1.blah">
<select name="whatever" id="1_1" onchange="this.form.radiobutton.checked=true;">
<option>0
<option>1
</select>
<input type="reset">
</form>
Note that you need a reset button, otherwise it's impossible to uncheck the radio button without reloading the page (or the user running a script).
