Radio Button Sleuth Page
This is an example of how to use javascript to find the value of the checked radio button in a form.
< html >
< head >
< script >
function checkValue() {
var groupLevelArrayLength = document.forms[0].routeToLevel.length;
for(var i = 0; i < groupLevelArrayLength; i++ ){
if(eval("document.forms[0].routeToLevel["+i+"].checked") == true){
var routeToLevel = document.forms[0].routeToLevel[i].value;
}
}
alert("routeToLevel selected is = " + routeToLevel);
return false;
}
</ script >
</ head >
< body >
< form onsubmit = " return checkValue();" >
< input type = " radio" name = " routeToLevel" value = " 100" >
< input type = " radio" name = " routeToLevel" value = " 150" >
< input type = " radio" name = " routeToLevel" value = " 200" >
< input type = " radio" name = " routeToLevel" value = " 300" >
< input type = " radio" name = " routeToLevel" value = " 400" >
< input type = " submit" value = " Check Value" onclick = " return checkValue();" >
</ form >
</ body >
</ html>
