我在我的MVC应用程序中使用jQuery Unobtrusive Validation。回发时,验证按照规定进行。但是,我有充分的理由阻止回发客户端。
我遵循多个网站上看到的规定方法......我尝试了许多不同的组合。但是,我仍然遇到以下错误:
"Cannot read property 'type' of undefined"
我的JAVASCRIPT看起来像:
当我调用'showErrors'时会发生错误......
function onValidateCity(e){
// Checks the value of my Kendo Combobox
var value = this.value();
if (value && this.selectedIndex === -1) {
// Yes, it reaches this part
var validator = $('#CityId').validate();
validator.showErrors({"CityId": "My custom error message!"});
}
}
我的MVC助手会创建以下HTML:
<span class="k-widget k-combobox k-header form-control">
<span tabindex="-1" unselectable="on" class="k-dropdown-wrap k-state-default">
<input name="CityId_input" class="k-input form-control" type="text" autocomplete="off" title="" maxlength="524288" role="combobox" aria-expanded="false" placeholder="-- Select City --" tabindex="0" aria-disabled="false" aria-readonly="false" aria-autocomplete="list" aria-owns="CityId_listbox" aria-busy="false" style="width: 100%;" />
<span tabindex="-1" unselectable="on" class="k-select">
<span unselectable="on" class="k-icon k-i-arrow-s" role="button" tabindex="-1" aria-controls="CityId_listbox">select</span>
</span>
</span>
<input autocomplete="off" class="form-control" data-val="true" data-val-required="The City field is required." id="CityId" name="CityId" type="text" value= "28dbddea-660d-4bbb-b063-f926b1153866" data-role="combobox" aria-disabled="false"
aria-readonly="false" novalidate="novalidate" style="display: none;" />
</span>
<span class="field-validation-valid text-danger" data-valmsg-for="CityId" data-valmsg-replace="true"></span>
MVC(确认)助手看起来像:
@ Html.ValidationMessageFor(model =&gt; model.CityId,“”,new {@class =“text-danger”})
答案 0 :(得分:0)
初始化validator
时,请对包含嵌套在其中的CityId
输入的元素执行此操作,而不是输入元素本身。它可以是form
或div
或span
。
这是在小提琴中工作的简化代码,我是针对span
做的:
的 http://jsfiddle.net/o0qhcbbL/1/ 强>
$('#button').click(function (e) {
onValidateCity(e)
})
function onValidateCity(e) {
var validator = $('#xx').validate();
validator.showErrors({
"CityId": "My custom error message!"
});
}
HTML:
<span id="xx">
<input id="CityId" name="CityId" type="text" />
</span>
<span id="button">select</span>
