【问题描述】：

我有一个包含我的数据库的一些记录的表。我正在尝试使用 JQuery 获取这些寄存器的 id，但我不知道该怎么做。

我该怎么做？

<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>

【解决方案1】：

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。

解决方案

<script type="text/javascript">

$(document).on('click', '.btnAbrirEmpresa', function(e){
    e.preventDefault(); 
    var pai = $(this).closest('tr'); 
    var id = this.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>
