I'd like to validate a form using the jquery validate plugin, but I'm unable to use the 'name' value within the html - as this is a field also used by the server app. Specifically, I need to limit the number of checkboxes checked from a group. (Maximum of 3.) All of the examples I have seen, use the name attribute of each element. What I'd like to do is use the class instead, and then declare a rule for that.
html
This works:
<input class="checkBox" type="checkbox" id="i0000zxthy" name="salutation" value="1" />
This doesn't work, but is what I'm aiming for:
<input class="checkBox" type="checkbox" id="i0000zxthy" name="i0000zxthy" value="1" />
javascript:
var validator = $(".formToValidate").validate({
rules:{
"salutation":{
required:true,
},
"checkBox":{
required:true,
minlength:3 }
}
});
Is it possible to do this - is there a way of targeting the class instead of the name within the rules options? Or do I have to add a custom method?
Cheers, Matt
You can add the rules based on that selector using .rules("add", options), just remove any rules you want class based out of your validate options, and after calling $(".formToValidate").validate({... });, do this:
$(".checkBox").rules("add", {
required:true,
minlength:3
});
