jQuery 没有获取属性值

Question

jQuery:

$(".close_invoice").confirm({
    title: 'Are you sure to delete it?',
    content: 'Click to Delete if you are sure else click on Close.',
    type: 'red',
    typeAnimated: true,
    buttons: {
        delete: {
            text: 'Delete',
            btnClass: 'btn-red',
            action: function() {
                alert($(this).attr("id"));
            }
        },
        close: {
            text: 'Close',
            btnClass: 'btn-blue',
            action: function() {}
        }
    }
});

HTML:

<button class="btn btn-sm green btn-outline filter-submit margin-bottom close_invoice" id="14" jc-attached="true"><i class="fa fa-times"></i> Close Invoice</button>

Anyone can please tell me Why it not taking the value of attribute ID. How can I get the value of attribute ID? It alerting undefined.

你不能在function object parameters使用this选择器..你可以把这个value保存到一个变量中，然后把它作为function paramater object's value
