data th JS每页只工作一次

data-th JS only works once per page

本文关键字:一次 工作 th JS data      更新时间:2023-09-26

我正在使用此CodePen中的代码来使我的表响应:http://codepen.io/anon/pen/myayee

我的网站上的一切都像他的例子一样工作,但我想在页面上添加一个以上的表。当我这样做时,只有页面上的第一个表得到了当浏览器变小时添加到其中的"data th=",其余的表都是空白的。我希望它被添加到页面上的所有表头中,但不确定如何更改他的代码来完成它

我更改了一些类,所以下面是我的代码(为了节省空间,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]);
  } 
}

您需要迭代所有表,然后迭代每个表中的所有行和单元格。试试这样的东西:

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]);
        }
    }    
}
