Question

<input type="radio" checked="checked" value="true" name="child">
<span class="label">Show</span>
<input type="radio" class="hide" value="false" name="child">
<span class="label">Hide</span>

and another radio button on the same page

<input type="radio" checked="checked" value="true" name="baby">
<span class="label">Show</span>
<input type="radio" class="hide" value="false" name="baby">
<span class="label">Hide</span>

I need to know if all the radio buttons having value="false" are checked using javascript.

Note: The radio button names are different

Answer 1

You can try this:

function testRadios() {
    var r = document.getElementsByTagName("input");

    for (var i=0; i < r.length; i++) {
        if (   (r[i].type == "radio")
            && (r[i].value == "false")
            && (r[i].checked != "checked")) {
            return false;
    }
    return true;
}

PS: Use <label> instead of <span class="label">.
