我使用角度js提交表单。 我希望在提交后重置表单字段。
DEMO_ANGULAR JS
$scope.addUser = function()
{
$scope.errors = [];
$scope.msgs = [];
$scope.errors.splice(0, $scope.errors.length); // remove all error messages
$scope.msgs.splice(0, $scope.msgs.length);
$http.post("../admin/users/add_user", {'fname': $scope.fname, 'lname': $scope.lname, 'uname': $scope.uname,'gender': $scope.gender,'email': $scope.email,'mobile': $scope.mobile,'pass': $scope.pass}
).success(function(data, status, headers, config) {
if (data.msg != '')
{
$scope.msgs.push(data.msg);
$scope.get_users();
$scope.form_add.$setPristine();
$scope.currentRecord={};
}
else
{
$scope.errors.push(data.error);
}
}).error(function(data, status) { // called asynchronously if an error occurs
// or server returns response with an error status.
$scope.errors.push(status);
});
}
这是我添加用户的视图（HTML）表单：
<form name="form_add" method="post">
<ul>
<li style="color:red" ng-repeat="error in errors"> {{ error}} </li>
</ul>
<ul>
<li style="color:green" ng-repeat="msg in msgs"> {{ msg}} </li>
</ul>
<table class="table" cellspacing=10 cellpadding=10>
<tr>
<td>First Name: <input required type="text" ng-pattern="/[a-zA-Z]$/" ng-model="fname" name="fname" id="fname" value=""/><br/>
<span style="color:red" ng-show="form_add.fname.$dirty && form_add.fname.$invalid">
<span ng-show="form_add.fname.$error.required">First Name is required.</span>
<span ng-show="form_add.fname.$error.pattern">Invalid</span>
</span>
</td>
<td>Last Name: <input required type="text" ng-pattern="/[a-zA-Z]$/" ng-model="lname" name="lname" id="lname" value=""/><br/>
<span style="color:red" ng-show="form_add.lname.$dirty && form_add.lname.$invalid">
<span ng-show="form_add.lname.$error.required">Last Name is required.</span>
<span ng-show="form_add.lname.$error.pattern">Invalid</span>
</span>
</td>

<span style="color:red" ng-show="form_add.uname.$dirty && form_add.uname.$invalid">
<span ng-show="form_add.uname.$error.required">User Name is required.</span>
<span ng-show="form_add.uname.$error.pattern">Invalid: Minimum 6 characters and maximum 15 characters</span>
</span>
</td>
<td width="20%">Gender :<br/> <input type="radio" ng-model="gender" name="gender" id="r1" value="m" checked />Male
<input type="radio" ng-model="gender" name="gender" id="r2" value="f"/>Female</td>
</tr>
<tr>
<td>Email ID: <input type="text" required ng-pattern="/^[a-z]+[a-z0-9._]+@[a-z]+\.[a-z.]{2,5}$/" ng-model="email" name="email" id="email" value=""/><br/>
<span style="color:red" ng-show="form_add.email.$dirty && form_add.email.$invalid">
<span ng-show="form_add.email.$error.required">Email is required.</span>
<span ng-show="form_add.email.$error.pattern">Invalid email address.</span>
</span>
</td>
<td>Mobile : <input type="text" required ng-model="mobile" ng-pattern="/^[1-9]{1}[0-9]{9}$/" name="mobile" id="mobile" value=""/><br/>
<span style="color:red" ng-show="form_add.mobile.$dirty && form_add.mobile.$invalid">
<span ng-show="form_add.mobile.$error.required">Mobile is required.</span>
<span ng-show="form_add.mobile.$error.pattern">10 digits required</span>
</span>
</td>
<td>Password : <input required type="password" ng-model="pass" name="pass" id="pass" value=""/>
<span style="color:red" ng-show="form_add.mobile.$dirty && form_add.mobile.$invalid">
<span ng-show="form_add.mobile.$error.required">Mobile is required.</span>
<span ng-show="form_add.mobile.$error.pattern">10 digits required</span>
</span>
</td>
<td><button type="button" class="btn btn-primary" ng-click='addUser();' ng-disabled="form_add.$invalid">Save</button></td>
</tr>
</table>
<br/>
</form>
如何在提交后重置表单，以上代码中的任何更改？ 我的问题尚未解决！

您可以为您的模型尝试基础对象。参见示例
<form action="">
<label for="">Name</label>
<input type="text" ng-model="user.model">
<label for="">Email</label>
<input type="text" ng-model="user.email">
<label for="">Password</label>
<input type="password" ng-model="user.password">
<button type="submit">Submit</button>
</form>
for Angular
$scope.addUser = function()
{
$scope.errors = [];
$scope.msgs = [];
$http.post("your/desire/url", yourData)
.success(function(data, status, headers, config) {
if (data.msg != '')
{
//do something
//reseting form
$scope.user='';
}
else
{
$scope.errors.push(data.error);
}
}).error(function(data, status) {
$scope.errors.push(status);
});
}
完成提交表单后，您必须重置模型基础对象
$ scope.user = '';
我认为它会正常工作：）

你可以这样休息：
就像你有一个表格：
<form novalidate class="css-form">
Name: <input type="text" ng-model="user.name" required /><br />
E-mail: <input type="email" ng-model="user.email" required /><br />
Gender: <input type="radio" ng-model="user.gender" value="male" />male
<input type="radio" ng-model="user.gender" value="female" />female<br />
<input type="button" ng-click="reset()" value="Reset" />
<input type="submit" ng-click="update(user)" value="Save" />
</form>
因此，重置按钮的代码将起作用：
$scope.master = {};
if (form) {
form.$setPristine();
form.$setUntouched();
}
$scope.user = angular.copy($scope.master);
这肯定是短暂的工作

以这种方式解决： 我已使用此代码重置：
$scope.fname='';
$scope.lname='';
$scope.uname='';
$scope.email='';
$scope.mobile='';
$scope.pass='';
$scope.form_add.$setPristine();
