我有一个问题，我有一段时间无法解决。我有 mvc 应用程序，它将在成功登录后呈现登录页面，我必须重定向到特定页面。

登录身份验证由 Api 控制器完成，它将在成功身份验证时给我一个 json 位。我有一个关于如何在成功登录时进行重定向的问题。我正在使用 ecmascript 5 规范。我的登录表单中没有继承布局，所有组件和路由都在布局页面中注册的脚本中。这个登录是一种临时页面，下面是登录的 jsx 代码。及时帮助将不胜感激

var MyInput = React.createClass({
//onchange event
handleChange: function (e) {
    this.props.onChange(e.target.value);
    $("#diverror span").removeClass('alert');
    $("#diverror span").removeClass('alert-danger');
},
componentDidMount: function () {
    if (this.props.onComponentMounted) {
        this.props.onComponentMounted(this);//register this input in the           form
    }
},    

render: function () {
    var inputField;
        inputField = <input type={this.props.type} value={this.props.value} ref={this.props.name} name={this.props.name}
        className='form-control'  onChange={this.handleChange} />            
    return (
            <div className="form-group">
                <label htmlFor={this.props.htmlFor}>{this.props.label}</label>
    {inputField}
</div>
        );
}

});

所以基本上你只需通过上下文将路由器添加到类中，例如：

...
contextTypes: {
  router: React.PropTypes.object.isRequired  
}
...

然后如果条件正确

if (successCondition) {
  this.context.router.push('stateName');
}

您使用路由器重定向到新状态。

希望这可以帮助。

更新

var React = React; // <-- add Reach to the application
var Router = ReactRouter;
var Route = ReactRouter.Route;
var Routes = ReactRouter.Routes;
var Navigation = ReactRouter.Navigation;
var History = ReactRouter.History;

var LoginForm = React.createClass({
mixins: [History],
mixins: [Navigation],

// --> Add the router into the context
contextTypes: {
  router: React.PropTypes.object.isRequired  
}

...

                if (data == 0)
                {
                    this.context.router.push('stateName'); // --> push the new state if successful
                }
                else

...

我已在您提供的示例中添加了必要的位。我注意到您没有定义 React，或者将位添加到错误的位置可能是个问题。希望这可以帮助。
