Here is an example of how you can retrieve the selected checkboxes using a JavaScript function:
<html>
<head>
<script>
function getSelectedValues(elem) {
var elemNumber = document.myForm.test.length;
var selectedElems = [];
for(j = 0; j < elemNumber; j++) {
if(elem[j].checked) {
selectedElems.push(elem[j].value);
}
}
return selectedElems;
}
</script>
</head>
<body>
<form id="myForm" name="myForm">
<input type="checkbox" id="test" name="myCheckBox" value="test1">
Test 1
<input type="checkbox" id="test" name="myCheckBox" value="test2">
Test 2
<input type="button" value="Click Here"
onclick="alert(getSelectedValues(document.myForm.myCheckBox));">
</form>
</body>
</html>In the previous example when the user clicks on the button the selected checkboxes are displayed through an alert.
