我有一个包含数据库记录的表。我尝试使用JQuery获取这些寄存器的id，但我不知道如何做到这一点。
我怎么能这样做？
<script type="text/javascript">
$(document).ready(function(){
$('#btnAbrirEmpresa').click(function(){
//id register
var id = $(this).closest('tr').attr('[Empresa][id]');
alert(id);
var loading = $(".imageLoading");
$(document).ajaxStart(function () {
loading.show();
});
$(document).ajaxStop(function () {
loading.hide();
});
$.ajax({
accepts: {json: 'application/json'},
dataType:'json',
type: "POST",
url: "<?php echo $this->Html->url("/Empresas/openEmpresa.json")?>",
data: {"id":id},
success: function( data ){
console.log(data);
},
error: function (xhr, status) {
$(".message").html('Error: ' + status);
}
});
return false;
});
});
</script>
<div class="row">
<div class="col-lg-12">
<h1 class="page-header">Empresa</h1>
<!--loading-->

答案 0 :(得分：0)
解决了这个问题。我在$this->Html->link的id中添加了注册ID，并且工作正常。
