AngularJS提供了表單驗證，但是驗證的過程交互體驗很不好，比如重設密碼，重復密碼的時候一鍵入就會提示密碼不正確，現整理了兩種方法，僅供借鑒。
一，點擊提交驗證
<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">密碼</label> <div class="col-sm-8"> <input type="password" name="mycompwd" class="form-control" ng-model="mycompwd" placeholder="請輸入密碼"> </div> </div> <div class="form-group"> <label class="col-sm-2 control-label">重復密碼</label> <div class="col-sm-8"> <input type="password" name="resetmycompwd" class="form-control" ng-model="resetmycompwd" placeholder="再次輸入密碼" required> </div> <span style="color:red" ng-show="mycompwd!=resetmycompwd && reset_pwd.resetmycompwd.$dirty && reset_pwd.submitted ">密碼不一致</span> </div> <div class="form-group"> <button type="submit" class="btn btn-primary" >確認</button> <button type="button" class="btn btn-default" ng-click="resetpwd_cancle()">取消</button> </div></form>
當用戶試圖提交表單時，你可以在作用域中捕獲到一個submitted值，然后對表單內容進行驗證并顯示錯誤信息。
JS代碼
$scope.submitted = false;$scope.resetPwd = function(){ console.log(666); if($scope.reset_pwd.$valid && $scope.mycompwd == $scope.resetmycompwd){ console.log('重置成功,進行其他操作'); }else{ $scope.reset_pwd.submitted = true; }}親測可用。
第二種失去焦點驗證
<form action="" class="form-horizontal col-md-9" name="reset_pwd" ng-submit="resetPwd()"> <div class="form-group"> <label class="col-sm-2 control-label">密 碼</label> <div class="col-sm-8"> <input type="password" name="mycompwd" class="form-control" ng-model="mycompwd" placeholder="請輸入密碼"> </div> </div> <div class="form-group"> <label class="col-sm-2 control-label">重復密碼</label> <div class="col-sm-8"> <input ng-focus type="password" name="resetmycompwd" class="form-control" ng-model="resetmycompwd" placeholder="再次輸入密碼" required> </div> <span style="color:red" ng-show="mycompwd!=resetmycompwd && reset_pwd.resetmycompwd.$dirty && !reset_pwd.resetmycompwd.$focused ">密碼不一致</span> </div> <div class="form-group"> <button type="submit" class="btn btn-primary" >確認</button> <button type="button" class="btn btn-default" ng-click="resetpwd_cancle()">取消</button> </div></form>
JS代碼
app.directive('ngFocus',[function(){ var focusClass = 'ng-focused'; return{ restrict:'AE', require:'ngModel', link:function(scope,element,attrs,ctrl){ ctrl.$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標紅的地方。正是區分兩種方法的關鍵。
