我在下面有JQuery验证,只是确保在输入字段中写入了某些内容,我在html中也有maxlength。
但是,我希望有人可以对这种情况有所了解,并告诉我如何在下面的jquery代码中添加某种类型的minlength,这样我就不需要做任何额外的功能了?
$('#form1').submit(function (e) {
e.preventDefault();
}).validate({
rules: {
txtusername: {
required: true
},
txtfirstname: {
required: true
},
txtemail: {
required: true
},
txtpassword: {
required: true
},
passwordconfirm: {
required: true
}
},
messages: {
txtusername: {
required: "Please enter your Username."
},
txtfirstname: {
required: "Please enter your First Name."
},
txtemail: {
required: "Please enter your Email."
},
txtpassword: {
required: "Please enter your Password."
},
passwordconfirm: {
required: "Please enter your password again."
}
},
errorPlacement: function (error, element) {
error.appendTo(element.parent().prev());
},
submitHandler: function (form, user) {
CheckUser(form);
return false;
}
});
示例HTML -
<div data-role="fieldcontainer">
<label for="txtusername" data-theme="d">Username:</label>
<input type="text" id="txtusername" name="txtusername" maxlength="12" placeholder="Enter Username"/>
</div>

您可以使用以下内容:
rules:{
txtusername: {
required: true,
minlength: 3
},
}
