没有页面类型的Typo3 Extbase AJAX

有没有办法在不使用pageNum页面的情况下在Extbase扩展中创建AJAX调用？

编辑：

Helmut Hummel是TYPO3 CMS团队的成员,measured使用EID和Extbase比使用typeNum方法慢.但由于typeNum方法配置起来很麻烦,因此他开发了第三种方法.

扩展typoscript_rendering提供了一种直接调用Extbase操作的方法,无需额外配置.它包含一个生成此类链接的ViewHelper,可以在Fluid模板中使用：

{namespace h=Helhum\TyposcriptRendering\ViewHelpers}
<script>
var getParticipationsUri = '<h:uri.ajaxAction controller="Participation" action="listByCompetition" arguments="{competition:competition}" />';
</script>

这会生成一个URI,该URI调用我的“ParticipationController”的动作“listByCompetition”.您可以正常传递参数.

唯一的缺点是出于安全原因,扩展使用cHash来验证请求参数. cHash由GET提交,但您不能同时通过GET传递其他参数,因为它会使cHash无效.因此,如果要在此类请求中传递表单数据,则需要混合GET(用于有效的AJAX调用)和POST(用于提交用户数据)：

<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例子.你可以发布整个模型等)

EID方式：

是的,您可以使用EID(扩展ID)机制.官方声明没有哪种方式(pageType或eID)应该用于Extbase AJAX调用,它似乎只是一个品味问题.

有一个很好的教程,可以找到here,我在这里复制源代码：
