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]);
}
}

答案 0 :(得分:3)
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]);
}
}
}
