Typo3 Extbase AJAX没有页面类型 [英] Typo3 Extbase AJAX without page typenum
问题描述
是否有任何方法可以在Extbase扩展中创建AJAX调用而无需使用页面typeNum?
Is there any way to create AJAX calls in Extbase extension without using of page typeNum?
推荐答案
TYPO3 CMS小组成员Helmut Hummel，测量，将EID与Extbase一起使用比使用typeNum方法要慢.但是由于typeNum方法难以配置，因此他开发了第三种方法.
Helmut Hummel, a member of the TYPO3 CMS team, measured that using EID with Extbase is slower than using the typeNum approach. But since the typeNum approach is cumbersome to configure, there is a third way developed by him.
扩展名 typoscript_rendering 提供了一种无需额外配置即可直接调用Extbase操作的方法.它包含一个ViewHelper，它会生成这样的链接，并且可以在Fluid模板中像这样使用:
The extension typoscript_rendering provides a way to call Extbase actions directly without additional configuration. It contains a ViewHelper that generates such links and can be used like this in a Fluid template:
{namespace h=Helhum\TyposcriptRendering\ViewHelpers}
<script>
var getParticipationsUri = '<h:uri.ajaxAction controller="Participation" action="listByCompetition" arguments="{competition:competition}" />';
</script>
这将生成一个URI，该URI调用我的"ParticipationController"的动作"listByCompetition".您可以正常传递参数.
This generates an URI that calls the action "listByCompetition" of my "ParticipationController". You can pass arguments normally.
唯一的缺点是出于安全原因，该扩展使用cHash来验证请求参数. cHash由GET提交，但是您不能同时通过GET传递其他参数，因为它将使cHash无效.因此，如果要在这样的请求中传递表单数据，则需要混合使用GET(用于有效的AJAX调用)和POST(用于提交用户数据):
The only downside is that for security reasons, the extension uses the cHash to validate the request arguments. The cHash is submitted by GET but you cannot pass additional arguments by GET at the same time because it would invalidate the cHash. So if you want to pass form data in such a request, you need to mix GET (for a valid AJAX call) and POST (for submitting user data):
<script>
var createAddressUri = '<h:uri.ajaxAction controller="Address" action="create" />';
$body.on('submit', '#myForm', function(e) {
e.preventDefault();
emailAddress = $('#myForm').find('#email');
if (typeof(emailAddress) === 'string') {
$.ajax({
url: createAddressUri,
type: 'POST',
data: { 'tx_myext_pluginname[address][email]' : emailAddress},
success: function() {
// things to do on success
}
})
}
});
</script>
(当然，这只是一个非常基本的示例.您可以发布整个模型，等等.)
(Of course this is only a very basic example. You might post whole models etc.)
EID方式:
是的，您可以为此使用EID(扩展ID)机制.没有官方声明应使用哪种方式(pageType或eID)进行Extbase AJAX调用，这似乎只是一个问题.
Yes, you can use the EID (Extension ID) mechanism for that. There is no official statement which way (pageType or eID) should be used for Extbase AJAX calls and it seems to be just a matter of taste.
在此处可以找到一个不错的教程我将源代码复制到这里:
There is a nice tutorial that can be found here and I copy the source code in here:

请参阅此脚本的用法"部分，该部分说明了如何注册eID.该脚本适用于TYPO3 6.1和更高版本.
Have a look at the "usage of this script" section that explains how to register the eID. The script works with TYPO3 6.1 and higher.
