javascript - 使用jquery在td中查找div

Question

我正在尝试从第 15 td 列获取 div 并将 div 的宽度设置为 300px。

我有表格摘要来识别该表格。如何设置宽度？

<table  summary="Copy and Design RFP">
....
...
/* column15*/
<td class="ms-vb2">
    <div dir="">1/9/14 - 1st draft sent</div>
</td>

到目前为止我已经写了

 $(document).ready(function () {
        if (window.location.href.indexOf("dept/mkt/Lists/Request for Projects/Active Projects.aspx") > -1) {
            $('table[summary="Copy and Design RFP"] tr td:nth-child(15)').each(function() {
                var id = $(this).find('div'); // This is not working
            });
        }
    });

Answer 1

使用nth-child选择器:

$('table[summary="Copy and Design RFP"] td:nth-child(15) div').css('width', '300px');
