I have the following code:
$(document).ready
(
function ()
{
$.validator.addMethod(
"lessThan",
function (value, element, param)
{
// bind to the blur event of the target in order to revalidate whenever the target field is updated
var target = $(param)
.unbind(".validate-lessThan")
.bind
(
"blur.validate-lessThan",
function ()
{
$(element).valid();
}
);
return parseFloat(value) <= parseFloat(target.val());
},
"Valoarea trebuie sa fie mai mica sau egala decat valoarea initiala"
);
}
);
$('#gvListDetaliiElemTranAdaugare input[name$=Valoare]').each
(
function (index, domEle)
{
$(this).rules
(
"add"
, {
required: true,
minlength: 1,
range: [0.1, Number.MAX_VALUE],
lessThan: '#ListaDetaliiElemTranModelAdaugare_' + index + '__ValoareRamasa',
messages:
{
required: "Valoarea este necesara!",
minlength: "Valoarea este necesara!",
range: "Valoarea este necesara!",
lessThan: "Valoarea trebuie sa fie mai mica sau egala cu " + $('#ListaDetaliiElemTranModelAdaugare_' + index + '__ValoareRamasa').val()
}
}
);
}
);
The code fails then it reeaches $(this).rules() with: Uncaught TypeError: Cannot read property 'nodeName' of null.
the html returned by $('#gvListDetaliiElemTranAdaugare input[name$=Valoare]') is:
[

I have found the problem.
The problem was that the HTML I was trying to validate was not contained within a
<form>...</form>tag.As soon as I did that, I had a
contextthat was not null.
