radiobuttonlist selected value javascript

Question

just want to ask, is there an equivalent selectedvalue in this code? like

<%=radiobuttonlistID.ClientID.SelectedValue="1"%> ?

I'm trying to find an equivalent code to this like

radiobuttonlistID.SelectedValue = "1"; I'm asking is there an extension in ClientID equivalent to selectedvalue?

Answer 1

<script type="text/javascript">
    function GetRadioButtonSelectedValue() {
        var AspRadio = document.getElementById('<%= Aspradiobuttonlist.ClientID %>');
        var AspRadio_ListItem = document.getElementsByTagName('input');
        for (var i = 0; i < AspRadio_ListItem.length; i++) {

            if (AspRadio_ListItem[i].checked) {
                var lblAspradiobuttonValue = document.getElementById('<%= lblAspradiobuttonValue.ClientID %>');

                lblAspradiobuttonValue.innerHTML = '<b>Selected Value:</b> ' + AspRadio_ListItem[i].value + '<br/>';
                lblAspradiobuttonValue.innerHTML += '<b>Selected Text:</b> ' + AspRadio_ListItem[i].parentNode.getElementsByTagName('label')[0].innerHTML;
            } //end if

        } // end for

    } //end function
</script>

Answer 2

I hope to understand what you need... Suppose you have this html code:

<form id="radiolist">
    <input type="radio" name="sex" id="male" value="male" >Male
    <br>
    <input type="radio" name="sex" id="female" value="female">Female
</form>

this javascript does what you want

<script>
    document.getElementById("male").checked = true;
</script>

Bye...
