' while(tbody.firstChild) { tbody.removeChild(tbody.firstChild) } tbody.appendChild(div.firstChild.firstChild)} 用一个div来包含一个table,然后删除tbody里的所有元素,最后给tbody添加div的第一个元素的第一个元素,即div>table>tr。 当然还有一个更精简的版本,它直接采用replaceChild方法替换 复制代码 代码如下:function setTBodyInnerHTML(tbody, html) { var div = document.createElement('div') div.innerHTML = '
' + html + '
' tbody.parentNode.replaceChild(div.firstChild.firstChild, tbody)} 从MSDN上记录上看 col、colGroup、frameset、html、head、style、table、tfoot、tHead、title和tr的innerHTML都是只读的(IE6-IE9)。 The innerHTML property is read-only on the col, colGroup, frameSet, html, head, style, table, tBody, tFoot, tHead, title, and tr objects. You can change the value of the title element using the document.title property. To change the contents of the table, tFoot, tHead, and tr elements, use the table object model described in Building Tables Dynamically. However, to change the content of a particular cell, you can use innerHTML.
