AngularJS提供了表单验证，但是验证的过程交互体验很不好，比如重设密码，重复密码的时候一键入就会提示密码不正确，现整理了两种方法，仅供借鉴。
一，点击提交验证
<form action="" class="form-horizontal col-md-9" name="reset_pwd" ng-submit="resetPwd()">
<div class="form-group">
<label class="col-sm-2 control-label">密码</label>
<div class="col-sm-8">
<input type="password" name="mycompwd" class="form-control" ng-model="mycompwd" placeholder="请输入密码">
</div>
</div>
<div class="form-group">
<label class="col-sm-2 control-label">重复密码</label>
<div class="col-sm-8">
<input type="password" name="resetmycompwd" class="form-control" ng-model="resetmycompwd" placeholder="再次输入密码" required>
</div>
<span style="color:red" ng-show="mycompwd!=resetmycompwd && reset_pwd.resetmycompwd.$dirty && reset_pwd.submitted
">密码不一致</span>
</div>
<div class="form-group">
<button type="submit" class="btn btn-primary" >确认</button>
<button type="button" class="btn btn-default" ng-click="resetpwd_cancle()">取消</button>
</div>
</form>
当用户试图提交表单时，你可以在作用域中捕获到一个submitted值，然后对表单内容进行验证并显示错误信息。
JS代码
$scope.submitted = false;
$scope.resetPwd = function(){
console.log(666);
if($scope.reset_pwd.$valid && $scope.mycompwd == $scope.resetmycompwd){
console.log('重置成功,进行其他操作');
}else{
$scope.reset_pwd.submitted = true;
}
}
亲测可用。
第二种失去焦点验证
<form action="" class="form-horizontal col-md-9" name="reset_pwd" ng-submit="resetPwd()">
<div class="form-group">
<label class="col-sm-2 control-label">密 码</label>
<div class="col-sm-8">
<input type="password" name="mycompwd" class="form-control" ng-model="mycompwd" placeholder="请输入密码">
</div>
</div>
<div class="form-group">
<label class="col-sm-2 control-label">重复密码</label>
<div class="col-sm-8">
<input ng-focus type="password" name="resetmycompwd" class="form-control" ng-model="resetmycompwd" placeholder="再次输入密码" required>
</div>
<span style="color:red" ng-show="mycompwd!=resetmycompwd && reset_pwd.resetmycompwd.$dirty
&& !reset_pwd.resetmycompwd.$focused
">密码不一致</span>
</div>
<div class="form-group">
<button type="submit" class="btn btn-primary" >确认</button>
<button type="button" class="btn btn-default" ng-click="resetpwd_cancle()">取消</button>
</div>
</form>
JS代码
app.directive('ngFocus',[function(){
var focusClass = 'ng-focused';
return{
restrict:'AE',
require:'ngModel',
link:function(scope,element,attrs,ctrl){
ctrl.$focused = false;
element.bind('focus',function(e){
element.addClass(focusClass);
scope.$apply(function(){
ctrl.$focused = true;
});
element.bind('blur',function(e){
element.removeClass(focusClass);
scope.$apply(function(){
ctrl.$focused = false;
});
});
})
}
};
}]);
注意HTML标红的地方。正是区分两种方法的关键。
