Auto - Check a radio button when a link is Clicked

hmmmmmm help???
How could i Auto - Check a radio button when a link is Clicked?

if the update link (<a href="update.php">update</a>) is clicked,
its corresponding radio button must be clicked/checked also, how can i do that ?

can someone help me??

if not, what is the best way to get and update values from database??

 

You need to check into Javascript / AJAX (To access the database). jQuery is a library that will get you started and is easy to comprehend.

 

// set the radio button with the given value as being checked
// do nothing if there are no radio buttons
// if the given value does not exist, all the radio buttons
// are reset to unchecked
function setCheckedValue(radioObj, newValue) {
	if(!radioObj)
		return;
	var radioLength = radioObj.length;
	if(radioLength == undefined) {
		radioObj.checked = (radioObj.value == newValue.toString());
		return;
	}
	for(var i = 0; i < radioLength; i++) {
		radioObj[i].checked = false;
		if(radioObj[i].value == newValue.toString()) {
			radioObj[i].checked = true;
		}
	}
}
