I am new to Javascript. I have a code snippet like this:
<ul class="dropdown-menu dropdown-menu-right" onchange="onCompChange()">
<div class="radio" id = "compSelect">
<label><input type="radio" name="optradio">op1</label>
</br>
<label><input type="radio" name="optradio">op2</label>
</br>
<label><input type="radio" name="optradio">op3</label>
</div>
</ul>
On selecting a radio button, I want to know which option is selected (op1/op2/op3).
To get the value of the selected radioName item of a form with id myForm: $('input[name=radioName]:checked', '#myForm').val()
Here's an example:
$('#myForm input').on('change', function() {
var value = $('input[name=radioName]:checked', '#myForm').val();
console.log(value);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="myForm">
<input type="radio" name="radioName" value="1" /> 1 <br />
<input type="radio" name="radioName" value="2" /> 2 <br />
<input type="radio" name="radioName" value="3" /> 3 <br />
</form>
Think this helps you.
How about this:
<input type="radio" name="opt radio" onclick="check(this.value)" value="op1" >op1</label>
<input type="radio" name="opt radio" onclick="check(this.value)" value="op2" >op2</label>
<input type="radio" name="opt radio" onclick="check(this.value)" value="op3" >op3</label>
in your .js:
function check(value) {
//... use your value
}
<ul class="dropdown-menu dropdown-menu-right" > <div class="radio" id = "compSelect"> <label><input onchange="onCompChange(this)" type="radio" name="optradio">op1</label> </br> <label><input onchange="onCompChange(this)" type="radio" name="optradio">op2</label> </br> <label><input onchange="onCompChange(this)" type="radio" name="optradio">op3</label> </div> </ul> <script type = "text/javascript" language = "javascript"> function onCompChange(radio){ var content = radio.parentElement.innerHTML; var output = content.replace(/<\\/?[^>]+(>|$)/g, ""); alert(output); } </script>
