我有以下代码:
$(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 " + $('#ListaDetaliiElemTranModelAdaugare_' + index + '__ValoareRamasa').val()
}
}
);
}
);
代码失败，然后通过
Uncaught TypeError: Cannot read property 'nodeName' of null到达$(this).rules()。$('#gvListDetaliiElemTranAdaugare input[name$=Valoare]')返回的html是:[
<input data-type="decimal" id="ListaDetaliiElemTranModelAdaugare_0__Valoare" name="ListaDetaliiElemTranModelAdaugare[0].Valoare" onchange="OnValoareChange($(this).val(), 18590 , 0)" type="text" value="0.00000000000">

最佳答案
我发现了问题。
问题是我要验证的HTML不在<form>...</form>标记内。
这样做后，我的 context 不为空。
