我正在开发一个类似提交表单的项目,所以我决定将一些字段移到指令中。
表单示例:
<div loading class="col-sm-12" ng-controller="Controller">
<form name="myForm" role="form" novalidate>
<fieldset class="lines-header-border">
<div class="col-sm-6">
<div class="form-group">
<label class="col-sm-4 control-label">Date</label>
<div class="col-sm-7">
<date-field
model="myModel"
date-picker-options="datePickerOptions"
for-name="date"
for-ng-class="myForm.date.$invalid"
is-required="true"/>
</div>
<div class="col-sm-4">
<input class="form-control"
name="amount"
ng-model="amount"
ng-class="{ 'has-error' : myForm.amount.$invalid }"
required/>
</div>
</div>
</fieldset>
</form>
</div>
日期字段指示:
.directive('dateField', function() {
return {
restrict: 'E',
replace: true,
scope: {
model: '=',
datePickerOptions: '=',
isRequired: '@',
forName:'@',
forNgClass: '&'
},
template: '<input ui-date="datePickerOptions" type="date" name="{{forName}}" class="form-control" ng-model="model" ng-class="{ \'has-error\' : forNgClass()}" ng-required="isRequired"/>'
};
});
提交时的验证问题:
其他字段在表单提交按钮单击时得到验证,但此日期字段不是。我认为问题出在for-ng-class="myForm.date.$invalid"
。
有什么建议吗?
答案 0 :(得分:1)
在您的情况下,您想要访问控制器范围变量&#34; myForm.date。$ invalid&#34;通过指令属性&#34; for-ng-class&#34;。分配&#34; @&#34;到指令范围变量&#34; forNgClass&#34;用于双向数据绑定。输入字段更改后,类将相应更新。
scope:{
.....
forNgClass: "@"
.....
}
我实现了一个简单的例子:
UPDATE:由于angular不能动态生成输入元素的名称属性。我们需要将dateField的input元素包装在一个内部形式中(通过使用ngForm指令)。您可以参考Angular Doc了解有关角度世界中嵌套表单的更多详细信息。
