Is it possible to check for a custom value (besides True / False) on a checkbox using the jQuery Validation plugin?
For example :
<input id="test" type="checkbox" name="test" value="something">
I cannot find a way to check for 'something' being the value. For specific reasons I cannot just use 'true' as the value.
Try this :
$('#test').attr('value');
You can use it inside custo validation method.
To declare custom rule :
$.validator.addMethod("myRule", function(value, element) {
var v = element.attr('value');
if(v === 'something') {
return true;
}
return true;
}, $.validator.format('my message') );
To set the custom rule on a field :
$('#form').validate({
rules : {
test : {
myRule : true
}
}
});
Use:
$("#test").val()
or if you want to get value in change event then:
demo : http://jsfiddle.net/qsDn5/16/
$("#test").change(function(){
alert(this.value);
});
You can add the rule using the addMethod which then returns a boolean based on the result of a test like so:
// Add Custom Method
$.validator.addMethod('someTest', function(value, element){
return 'something' === value;
}, $.validator.format('Custom Message'));
// Use Custom Method
$('#theForm').validate({
rules: {
checkBoxField: {
someTest: true
}
...
});
I hope this helps!
Try Jquery Validation plugin,
<form id="myform">
<input type="checkbox" name="test[]" />x
<input type="checkbox" name="test[]" />y
<input type="checkbox" name="test[]" />z
<input type="submit" />
</form>
<a id="docs" href="http://docs.jquery.com/Plugins/Validation" target="_blank">Validation Documentation</a>
Code:
$(document).ready(function () {
$('#myform').validate({ // initialize the plugin
rules: {
'test[]': {
required: true,
maxlength: 2
custommethod: true
}
},
messages: {
'test[]': {
required: "You must check at least 1 box",
maxlength: "Check no more than {0} boxes"
}
},
submitHandler: function (form) { // for demo
alert('valid form submitted'); // for demo
return false; // for demo
}
});
});
Update: http://jsfiddle.net/aJBK9/2/
Use the addMethod in jquery Validation,
$.validator.addMethod("custommethod", function(value, element) {
if (value==="something"){return true;}
return false;
}, "Value must be some thing");
