data-th JS每页只能运行一次

我正在使用此CodePen中的代码使我的表格响应:http://codepen.io/anon/pen/myayee

我网站上的所有内容都在他的示例中工作,但我想在页面中添加多个表格。当我这样做时,只有页面上的第一个表格得到" data-th ="当浏览器变小时添加到其中,其余表是空白的。我希望它被添加到页面上的所有表头,但不知道如何更改他的代码来完成它。

我改变了一些类,所以这里是我的代码(为了空间而减少了表格):

//JS FOR RESPONSIVE TABLES
var headertext = [],
headers = document.querySelectorAll(".responsive th"),
tablerows = document.querySelectorAll(".responsive th"),
tablebody = document.querySelector(".responsive tbody");

for(var i = 0; i < headers.length; i++) {
  var current = headers[i];
  headertext.push(current.textContent.replace(/\r?\n|\r/,""));
} 
for (var i = 0, row; row = tablebody.rows[i]; i++) {
  for (var j = 0, col; col = row.cells[j]; j++) {
    col.setAttribute("data-th", headertext[j]);
  } 
}

HTML

<table class="responsive mesh">
<thead>
<tr>
<th>Phifer</th>
<th>Openness</th>
<th>Sun/UV</th>
<th>Protection</th>
<th>Sample</th>
</tr>
</thead>
<tbody>
<tr>
<td>18/14 - Charcoal</td>
<td>58%</td>
<td>Up To 40%</td>
<td>Blockage</td>

</tr>

您需要迭代所有表,然后遍历每个表中的所有行和单元格。尝试这样的事情:

var tables = document.querySelectorAll(".responsive"),
    tbody, headers, headertext, i, j, k;

for (i = 0; i < tables.length; i++) {

    tbody = tables[i].tBodies[0];
    headers = tables[i].tHead.rows[0].children;
    headertext = [];

    for (j = 0; j < headers.length; j++) {
        headertext.push(headers[j].textContent.trim());
    }

    for (j = 0; j < tbody.rows.length; j++) {
        for (k = 0; k < tbody.rows[j].cells.length; k++) {
            tbody.rows[j].cells[k].setAttribute("data-th", headertext[k]);
        }
    }    
}
