从javascript数组创建HTML表

I want to get all classes of the HTML element on my page, split it and store it in array. After that I want to write it into my table in the div with the id "table" which I already have.

我想在我的页面上获取HTML元素的所有类，将其拆分并将其存储在数组中。之后我想将它写入div中的表格，其中包含我已经拥有的id“table”。

So far I have this code:

到目前为止，我有这个代码：

var string = $('html').attr('class');
var array = string.split(' ');
var arrayLength = parseInt(array.length);

for (i=0; i<=arrayLength; i++) {
    // code
}

<div id="test><!-- table goes here --></div>

Can you help me with the rest?

其他人可以帮助我吗？

btw, the HTML element has the classes from a modernizr.js.

顺便说一下，HTML元素有来自modernizr.js的类。

PS: The code is combination of pure JS and jQuery. Because I dont know how to get all classes of the HTML element in pure JS. Any Idea?

PS：代码是纯JS和jQuery的组合。因为我不知道如何在纯JS中获取HTML元素的所有类。任何想法？

3 个解决方案

If you're trying to remove jQuery altogether use this:

如果您尝试删除jQuery，请使用以下命令：

// Get array of classes without jQuery
var array = document.getElementsByTagName('html')[0].className.split(/\s+/);

var arrayLength = array.length;
var theTable = document.createElement('table');

// Note, don't forget the var keyword!
for (var i = 0, tr, td; i < arrayLength; i++) {
    tr = document.createElement('tr');
    td = document.createElement('td');
    td.appendChild(document.createTextNode(array[i]));
    tr.appendChild(td);
    theTable.appendChild(tr);
}

document.getElementById('table').appendChild(theTable);

if you have a table already in the html

如果你已经在html中有一个表

<div id="test><table >
    </table>
</div>

you can simply append new rows to it,

你可以简单地向它添加新行，

var string = $('html').attr('class');
var array = string.split(' ');
var arrayLength = parseInt(array.length);

for (i=0; i<=arrayLength; i++) {
  $("#test table") .append('<tr><td>'+array[i]+'</td></tr>') 
}

#3

It is not clear if you want the class names per row or per column. These examples are one class name per row. Try this:

目前尚不清楚您是想要每行还是每列的类名。这些示例是每行一个类名。尝试这个：

var elm = $('#test'),
    table = $('<table>').appendTo(elm);

$(document.documentElement.className.split(' ').each(function() {
    table.append('<tr><td>'+this+'</td></tr>');
});

I used native code to get the classNames of the HTML element: document.documentElement.className, but you might as well use $('html').attr('class').

我使用本机代码来获取HTML元素的classNames：document.documentElement.className，但您也可以使用$（'html'）。attr（'class'）。

A native JS example using innerHTML:

使用innerHTML的原生JS示例：

var d = window.document,
    elm = d.getElementById('test'),
    html = '<table>',
    classes = d.documentElement.classNames.split(' '),
    i = 0;

for(; classes[i]; i++) {
    html += '<tr><td>' + classes[i] + '</td></tr>';
}

elm.innerHTML = html + '</table>;
