我想使用jQuery Validate插件的自定义验证方法(addMethod)验证文本框,但我的代码不起作用。任何人都可以帮我找到错误吗?我以前从未使用过自定义验证方法,所以我很难找到我在这段代码中出错的地方。
这是我的代码:
$(document).ready(function () {
jQuery.validator.setDefaults({
// where to display the error relative to the element
errorPlacement: function(error, element) {
error.appendTo(element.parent().find('div.myErrors'));
}
});
jQuery.validator.addMethod(
"selectnic"
function(value,element){
if(element.value == /^[0-9]{9}[vVxX]$/)
return false;
else return true;
},
"wrong nic number"
);
$('#basicDetails').validate({ // initialize the Plugin
rules: {
fname: {
required: true,
lettersonly: true,
},
lname: {
required: true,
lettersonly: true,
},
},
messages: {
fname: {
required:"Please enter your first name",
lettersonly: "Login format not valid",
},
lname: {
required:"Please enter your last name",
lettersonly: "Login format not valid",
},
},
submitHandler: function (form) {
alert('valid form submitted');
return false;
}
});
});
.. html代码......
<form action="#" method="post" id="basicDetails" runat="server">
<table width="68%" border="0" cellpadding="6" cellspacing="6">
<tr>
<td> </td>
<td> First name </td>
<td>:</td>
<td><input type="text" name="fname" id="fname" class="textbox" placeholder="Required field"/><div class="myErrors"></div></td>
<td align="right"> Last name :</td>
<td><input type="text" name="lname" class="textbox" id="lname" placeholder="Required field"/><div class="myErrors"></div></td>
</tr>
<tr>
<td> </td>
<td width="147" > NIC no </td>
<td> : </td>
<td width="172"><input type="text" name="nic" id="nic" class="textbox" placeholder="Required field"/><div class="myErrors"></div></td>
<td width="167" align="right">Passport no :</td>
<td width="167" id="showPP"> <input type="text" name="passport" class="textbox" id="ppnu" placeholder="Required field"/></td>
</tr>
<tr>
<td> </td>
<td> </td>
<td colspan="3"><input type="submit" name="submit" value="Submit "class="submit" id="submit" />
<input type="submit" name="reset" value="Reset "class="reset" />
</td>
</tr>
</table>
</form>
.....编辑我的代码....
$(document).ready(function () {
jQuery.validator.setDefaults({
// where to display the error relative to the element
errorPlacement: function(error, element) {
error.appendTo(element.parent().find('div.myErrors'));
}
});
jQuery.validator.addMethod("selectnic", function(value, element){
if (/^[0-9]{9}[vVxX]$/.test(value)) {
return false;
} else {
return true;
};
}, "wrong nic number");
$('#basicDetails').validate({ // initialize the Plugin
rules: {
fname: {
required: true,
lettersonly: true,
},
lname: {
required: true,
lettersonly: true,
},
nicnumber: {
// other rules,
selectnic: true // <- declare the rule someplace!
}
},
messages: {
fname: {
required:"Please enter your first name",
lettersonly: "Login format not valid",
},
lname: {
required:"Please enter your last name",
lettersonly: "Login format not valid",
},
},
submitHandler: function (form) { // for demo
alert('valid form submitted'); // for demo
return false; // for demo
}
});
});

以下进展编辑概述了三个不同的问题。
1)
您错过了selectnic
和function(
之间的逗号。
此外,在使用regex
...
jQuery.validator.addMethod("selectnic", function(value, element){
if (/^[0-9]{9}[vVxX]$/.test(value)) {
return false; // FAIL validation when REGEX matches
} else {
return true; // PASS validation otherwise
};
}, "wrong nic number");
编辑:此答案假定您的原始regex
和逻辑都正确。当false
匹配时,您的逻辑将返回regex
。 false
表示验证失败,您将看到错误消息。
2)编辑2:
创建新方法后,您还必须使用它们。我没有看到代码中任何地方使用的selectnic
规则/方法。
示例强>:
rules: {
myFieldName: {
// other rules,
selectnic: true // <- declare the rule someplace!
}
}
3)编辑3:
最后,OP的原始true/false
逻辑向后倾斜。他希望在正则表达式匹配时进行验证...因此,需要return true
。
if (/^[0-9]{9}[vVxX]$/.test(value)) {
return true; // PASS validation when REGEX matches
} else {
return false; // FAIL validation
};

这是我的解决方案,包括希腊字符。
$.validator.addMethod('alphabet', function (value, element) {
let regExName = /^[A-Za-zΑ-Ωα-ωίϊΐόάέύϋΰήώ]+$/;
return (regExName.test(value));
}, 'There are non alphabetic characters!');
$("#orderForm").validate({
rules: {
first_name: {
required: true,
alphabet: true
}
});
