我是angular JS的新手,我创建了一个

的表单

HTML

<div data-ng-controller="ReservationController"
    <form class="form-horizontal" role="form">
            <div class="form-group">
              <div class="col-sm-10">
                <label>Guest Name</label>
                <input type="text" class="form-control" placeholder="" ng-model="res_guest_name" required>
              </div>
            </div>

            <div class="form-group">
              <div class="col-sm-10">
                <label>Phone</label>
                <input type="phone" class="form-control"  ng-model="res_member_phone">
              </div>
            </div>
            <div class="form-group">
              <div class="col-sm-10">
                <label>FAX</label>
                <input type="phone" class="form-control"  ng-model="res_member_fax">
              </div>
            </div>
            <div class="form-group">
              <div class="col-sm-10">
                <label>Email</label>
                <input type="email" class="form-control"  ng-model="res_member_email" required>
              </div>
            </div>
          <div class="form-group">
              <div class="col-sm-offset-8 col-sm-10">
                <button type="submit" class="btn btn-success" ng-click="res_save()">Save Changes</button>
              </div>
            </div> 
          </form>
          </div>

CONTROLLER

  function ReservationController($scope, $http,       $cookieStore,$location,$filter) {
     $scope.res_save = function()
      {
       var save_res ="https://pbg.com/save_form.html?contactid="+conId+"&token="+token+"&id="+$scope.resId+"&page=edit&guest_name="+$scope.res_guest_name+"&phone="+$scope.res_member_phone+"&fax="+$scope.res_member_fax+"&email="+$scope.res_member_email;
$http.get(save_res).success(function(response) {
    alert('success');
      });       
      }
      }

即使必填字段留空,我的表单仍会提交。它显示错误,然后提交。

显然它会提交您未处理提交表格的表格。您只是管理错误: - )

使用ng-disabled="myForm.$invalid" 其中myForm是表单上的name字段 <form class="form-horizontal" name="myForm" role="form">

  <button type="submit" class="btn btn-success" ng-disable="myForm.$invalid" ng-click="res_save()">Save Changes</button>

如果您不希望此按钮被禁用,则可以使用

<button type="submit" class="btn btn-success" ng-click="res_save(myForm.$valid)">Save Changes</button>

在控制器中

   $scope.res_save = function(valid)
         {
           if(valid){
           var save_res ="https://pbg.com/save_form.html?contactid="+conId+"&token="+token+"&id="+$scope.resId+"&page=edit&guest_name="+$scope.res_guest_name+"&phone="+$scope.res_member_phone+"&fax="+$scope.res_member_fax+"&email="+$scope.res_member_email;
    $http.get(save_res).success(function(response) {
        alert('success');
          }); 
        }      
          }

在保存之前,您没有检查表单有效状态,当表单无效时,不要指望angular会神奇地停止保存。

您应该查看ng-submit的文档。如果将res_save函数移动到表单上的ng-submit中(并删除了对提交输入的ng-click),它将针对必填字段进行验证,防止执行函数直到它们有效。
