我得到了行动" pega"在控制器帖子中:
public function pega($id = null)
{
$posts = $this->Post->findById($id);
foreach($posts as $pok)
{
$foda = $pok['love'];
}
$this->set('foda', $foda);
$this->set('_serialize', array('foda'));
}
在我的布局中,我尝试执行请求以捕获函数中的数据" pega"并将内置标签html:
<script>
var xmlhttp = new XMLHttpRequest();
var url = "http://localhost:81/booklandia/posts/pega/<?php echo $post['Post']['id'];? >.json";
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
var out = JSON.parse(xmlhttp.responseText);
function loap (){
var arr = out[0];
document.getElementById("id01").innerHTML = arr;
}
}
}
xmlhttp.open("GET", url, true);
xmlhttp.send();
