我要AJAX调用结束后显示出一些闪光的消息。我做这样的..

I want to show some flash message after completion of AJAX call. I am doing like this ..

控制器动作 -

def subscribe()
{
    def subscribe = new Subscriber()
    subscribe.email = params.subscribe
    if (subscribe.save())
    {
        flash.message = "Thanks for your subscribtion"
    }

}

查看部分 -

Subscribe :
    <g:formRemote onSuccess="document.getElementById('subscribeField').value='';" url="[controller: 'TekEvent', action: 'subscribe']" update="confirm" name="updateForm">
       <g:textField name="subscribe" placeholder="Enter your Email" id="subscribeField" />
       <g:submitButton name="Submit" />
    </g:formRemote >
    <div id="confirm">
       <g:if test="${flash.message}">
           <div class="message" style="display: block">${flash.message}</div>
       </g:if>
    </div>

我的AJAX的工作正常，但它没有显示我flash.message。后刷新页面就显示信息。怎么解决呢？

My AJAX working fine but it is not showing me flash.message. After refresh page it displaying message. How to solve it ?

推荐答案

当你使用AJAX页面内容不重新解析，让您的code：

When you use ajax your page content isn't re-parsed, so your code:

<g:if test="${flash.message}">
  <div class="message" style="display: block">${flash.message}</div>
</g:if>

将不会再次运行。

will not run again.

所以，我同意@詹姆斯的评论，闪光灯是不是更好的选择给你。

So I agree with @James comment, flash is not the better option to you.

如果你需要更新你的观点，去用JSON。 Grails的已经有一个变换器的，可用于本

If you need to update your view, go with JSON. Grails already have a converter that can be used to this:

if (subscribe.save()) {
  render ([message: "Thanks for your subscribtion"] as JSON)
}

和您的看法：

<g:formRemote onSuccess="update(data)" url="[controller: 'TekEvent', action: 'subscribe']"  name="updateForm">
  <g:textField name="subscribe" placeholder="Enter your Email" id="subscribeField" />
  <g:submitButton name="Submit" />
</g:formRemote >

<script type='text/javascript'>
  function update(data) {
    $('#subscribeField').val('');
    $('#confirm').html(data.message);
  }
</script>
