In this plunk我有一个Angular UI日期选择器和一条消息,只有在日期有效时才会显示。问题是即使form.$valid
为真,也始终显示消息。请注意,如果您输入有效或无效的日期,然后单击Validate
,警报将正确显示日期有效或无效。
为什么验证消息始终显示,即使form.$valid
为真?
的Javascript
var app = angular.module('ui.bootstrap.demo', ['ui.bootstrap']);
app.controller('ctl', function ($scope) {
$scope.dtFrom = new Date ();
$scope.config1 = {};
$scope.config1.opened = false;
$scope.open1 = function(event){
event.preventDefault();
event.stopPropagation();
$scope.config1.opened = true;
};
$scope.validate = function(form){
if (!form.$valid) {
alert("Date invalid");
}
else {
alert("Date valid");
}
}
});
HTML
<div ng-controller="ctl">
<form name="form1" ng-submit="validate(form1)" novalidate>
<p class="input-group" name="dtFrom" style="width:160px;margin-bottom:0px;">
<input type="text" class="form-control" ng-model="dtFrom"
is-open="config1.opened" uib-datepicker-popup="MM-dd-yyyy"
close-text="Close" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open1($event)">
<i class="glyphicon glyphicon-calendar"></i>
</button>
</span>
</p>
<span ng-show="!form1.dtFrom.$valid">Invalid Date</span>
<br/>
<button type="submit">Validate</button>
</form>
</div>
答案 0 :(得分:3)
您应该为输入
创建名称 <input type="text" class="form-control" ng-model="dtFrom"
is-open="config1.opened" uib-datepicker-popup="MM-dd-yyyy"
close-text="Close" name="date" />
<span ng-show="!form1.date.$valid">Invalid Date</span>
