如何将最小长度的验证添加到文本框并显示自定义错误消息?
我想验证以下内容:
以下是弹出模板的代码。模板中指定的最小长度不起作用,但maxlength工作正常。
<script id="popup_editor" type="text/x-kendo-template">
<table cellpadding="0" cellspacing="0">
<tr>
<td>
<label for="UserName"><b>UserName*</b></label>
</td>
<td>
<div class="control-row">
<input type="text"
name="UserName"
id="UserName"
class="k-input k-textbox"
required
**minLength**="6"
maxlength="8"
pattern="[a-zA-Z0-9]+"
validationMessage="Please enter username"/>
<span class="k-invalid-msg" data-for="UserName" ></span>
</div>
</td>
<td></td>
<td></td>
</tr>
<tr>
<td>
<div>
<label for="Password"><b>Password*</b></label>
</div>
</td>
<td>
<div class="k-edit-label">
<input type="password"
id="Password"
name="Password"
class="k-input k-textbox"required
validationMessage="Please enter Password"/>
<span class="k-invalid-msg" data-for="Password"></span>
</div>
</td>
<td>
<div>
<label for="ConfirmPassword" style=""><b>Confirm Password</b></label>
</div>
</td>
<td>
<div class="k-edit-label">
<input type="password"
id="ConfirmPassword"
name="ConfirmPassword"
class="k-input k-textbox"required
validationMessage="Please enter Confirm Password"/>
</div>
</td>
</tr>
<tr>
<td>
<div>
<label for="Company_Name"><b>Company Name*</b></label>
</div>
</td>
<td>
<div class="k-edit-label">
<input name="Company_Name"
id="Company_Name"
required
pattern="[a-zA-Z0-9]+"
validationMessage="Please enter Valid CompanyName"/>
</div>
</td>
<td></td>
<td></td>
</tr>
<tr>
<td>
<div>
<label for="First_Name"><b>First Name*</b></label>
</div>
</td>
<td>
<div class="k-edit-label">
<input type="text"
name="First_Name"
id="First_Name"
data-type="string"
data-bind="value:First_Name"
class="k-input k-textbox" required
pattern="[a-zA-Z]+"
validationMessage="Please enter FirstName"/>
</div>
</td>
<td>
<div>
<label for="Last_Name"><b>Last Name*</b></label>
</div>
</td>
<td>
<div class="k-edit-label">
<input type="text"
id="Last_Name"
name="Last_Name"
class="k-input k-textbox" required
pattern="[a-zA-Z]+"
validationMessage="Please enter LastName"/>
</div>
</td>
</tr>
<tr>
<td>
<div>
<label for="Address1"><b>Address1*</b></label>
</div>
</td>
<td>
<div class="k-edit-label">
<textArea style="resize: none;"
rows="5"
cols="18"
name="Address1"
maxlength="150"
id="Address1" required
pattern="[a-zA-Z0-9]+"
validationMessage="Please enter Address">
</textarea>
</div>
</td>
</tr>
</table>

您可以在网格的dataSource中为弹出式编辑添加自定义验证。
var dataSource = new kendo.data.DataSource({
transport: {
...
},
schema: {
model: {
id: "UserName",
fields: {
UserName: {}
Password: {}
ConfirmPassword: {}
Company_Name: {}
First_Name: {}
Last_Name: {}
Address1: {
validation: {
minLength: function (input) {
if (input.is("[name=UserName]")) {
return input.val().length >= 6;
}
return true;
},
match: function (input) {
if (input.is("[name=ConfirmPassword]")) {
return input.val() == $("#Password").val();
}
return true;
}
}
}
}
}
}
});
有几件事需要尊重: 验证会在弹出窗口中运行 ALL 输入元素,因此
return true
,否则您将收到未明确检查的每个输入的错误消息。如果没有传递返回值,则kendo会自动认为检查结果为错误。每个验证规则都需要自己的验证消息,否则您的验证工具提示框将仅显示没有任何文本的警告徽标。您可以在输入元素中将其添加为html属性( data- {validation rule} -msg ),如下所示:
<input type="text"
name="UserName"
id="UserName"
class="k-input k-textbox"
required
maxlength="8"
pattern="[a-zA-Z0-9]+"
validationMessage="Please enter username"
data-minLenght-msg="Username must be at least 6 characters"/>
<input type="password"
id="ConfirmPassword"
name="ConfirmPassword"
class="k-input k-textbox"
required
validationMessage="Please enter Confirm Password"
data-match-msg="Password and confirmation must be equal"/>
希望这有帮助

在规则中添加:
match: function (input) {
if ((input.is('[name=\'Password\']') || input.is('[name=\'ConfirmPassword\']'))&& $('#ConfirmPassword').length !== 0) {
if ($('#Password').val().length > 0 && $('#ConfirmPassword').val().length > 0) {
if (input.is('[name=\'Password\']')) {
return input.val() === $('#ConfirmPassword').val();
}
else if (input.is('[name=\'ConfirmPassword\']')) {
return input.val() === $('#Password').val();
}
}
}
return true;
},
minLength: function (input) {
if (input.is("[name=UserName]")) {
return input.val().length >= 6;
}
return true;
},
requiredAddress: function (input) {
if (input.is("[name=Address1]")) {
return $('#Address1').val() !== '' ? false : true;
}
return true;
}
