How To Change The Text Of A Radio Button

I have a radio button that needs to be dynamically updated from user input but the normal .val(), .text(), and .html() won't work. How can I change the text of a radio button using

Solution 1:

A radio input does not have text

All it is is this:

<inputtype="radio" />

Solution 2:

If your <label> has been properly associated with a particular radio button using the for attribute (as it should be)...

<form><inputtype="radio"id="example" /><labelfor="example">Clickyclick</label></form>

...you can just search the DOM for it using by the for attribute. Using jQuery:

<script>var yourElement = $("#example");
    var itsLabel = $("[for=" + yourElement.attr("id") + "]"); // <---
    itsLabel.css("color", "red");
</script>

Try it in this fiddle.

Solution 3:

A radio button doesn't have text associated with it.

But if you have a label tag / span tag next to the radio option. then you can use .next to access that element and change its text/html

DEMO

HTML:

<inputtype="radio" /><label>Option 1</label>

or

<inputtype="radio" /><span>Option 1</span>

JS:

var $label = $('input[type=radio]').next();
$label.text('Options'); 

Or you can use the below hack to change the text next to radio option. Note that the below code assumes that text is next to radio option.

DEMO

var isRadioLabel = 0;
$('div').contents().each(function() {
    if (this.nodeName == '#text' && isRadioLabel == 1) {
        isRadioLabel = 2;
    }
    if (isRadioLabel == 2) {
        this.nodeValue = 'Options';
        isRadioLabel = 0;
    }
    if (this.type == 'radio') {
        isRadioLabel = 1;
    } else {
        isRadioLabel = 0;
    }
});
