JQuery change value from radio button

Question

I have a variable called category that must change its value according to the selected radio button. The problem is that I do not get that at the click of a radio button or another, the value will change instantly.

This is the code I have:

<form>
<input type="radio" name="category" value="doctor" /> Doctor
<input type="radio" name="category" value="police" checked /> Policia
</form>

var category = $('[name="category"]:checked').val();

I need you to automatically change the value of the variable category when you click the radio buttons.

Answer 1

You need to change the value of category every time a user changes the selected radio button. Therefore you will need an event to trigger when the user clicks on a radio. You can check out the FIDDLE

var category = null;
$("input[name='category']").click(function() {
    category = this.value;
});
