use*_*591 5 ajax action param typo3 extbase
现在我设法从数据库中获取值,我想指定更多我想要传递的内容.
从对下面的事件函数作出反应的选择框中,我想读出一个值(记录的uid)并将其传递给我的ajaxAction:
var uid;
$('#mySelectBox').change(function() {
arguments = $(this).attr('value');
var uri = '<f:uri.action arguments="{uid: '+uid+'}" action="ajax" controller="Mycontroller1" pageType="89657201" />';
jQuery.getJSON(uri, function(result) {
// do something
});
});
我用参数试了一下,不知道这是不是正确的方法.另外,正如Marcus Biesioroff建议的那样,我应该将我的JS保存到一个单独的文件中,但是我必须自己编写uri而不是Fluid方式,对吧?
我的ajaxAction看起来像这样:
public function ajaxAction($uid) {
$dataFromRepo = $this->myRepository->findByUid($uid);
$resultArray = array(
"field1" => $dataFromRepo->getField1(),
"field2" => $dataFromRepo->getField2(),
"field3" => $dataFromRepo->getField3(),
"field4" => $dataFromRepo->getField4(),
);
return json_encode($resultArray);
}
我确信uid没有正确传递,其他一切都有效.
有一些错误:
<f:uri.action />在视图中:
<script type="text/javascript">
var actionsPathFromViewHelperSetInTheView
= '<f:uri.action action="ajax" controller="Mycontroller1" pageType="89657201" />';
</script>
<script type="text/javascript" src="path/to/ext/Public/yourExternal.js"></script>
<!-- of course this field may/should be created with Fluid's viewhelper -->
<select id="mySelectBox" onchange="performAjaxCall(this)">
<option value="1">Item 1</option>
<option value="2">Item 2</option>
<option value="3">Item 3</option>
</select>

在yourExternal.js(当然你需要改变tx_yourextkey_yourplugin你自己的前缀)
function performAjaxCall(selectFieldObj) {
$.ajax({
url: actionsPathFromViewHelperSetInTheView,
data:{
"tx_yourextkey_yourplugin[uid]":selectFieldObj.value
},
success:function (data) {
// do something with your json
alert('Load was performed.');
}
});

在你的控制器中:
public function ajaxAction() {
// try to always validate the incoming arguments
if (!$this->request->hasArgument('uid') || intval($this->request->getArgument('uid')) == 0) {
header('HTTP/1.1 400 Bad Request');
return json_encode(array('error'=> 'Bad request'));
}
$uid = intval($this->request->getArgument('uid'));
$dataFromRepo = $this->myRepository->findByUid($uid);
if ($dataFromRepo == null) {
header('HTTP/1.1 404 Not found');
return json_encode(
array('error'=> 'Not found or you have no access or something else... happens...')
);
}
$resultArray = array(
"field1" => $dataFromRepo->getField1(),
// etc...
);
return json_encode($resultArray);
}
