javascript - 用JS实现删除DOM 中的TABLE 的问题

问题描述

下面是页面的HTML。我想实现用JS操作DOM，把第一个table从页面上删除掉。我用的代码是：

document.getElementsByTagName('table')[0].innerHTML=''; //没效果OR document.getElementsByTagName('table')[0].parentNode.removeChild('table')错误信息：Uncaught TypeError: Failed to execute ’removeChild’ on ’Node’: parameter 1 is not of type ’Node’.at TypeError (native)at <anonymous>:2:54at Object.InjectedScript._evaluateOn (<anonymous>:878:140)at Object.InjectedScript._evaluateAndWrap (<anonymous>:811:34)at Object.InjectedScript.evaluate (<anonymous>:667:21)HTML：

问题解答

innerHTML改变的是表格内的内容，不是删除表格，当然从页面看起来innerHTML=''和删除的效果几乎一样，至于你的innerHTML=''为什么没效果，不好意思，HTML代码太长了，就没仔细看了removeChild中传的参数是节点，不是字符串

removeChild 接受一个 HTMLElement 元素，所以得 removeChild(document.getElementsByTagName('table')[0])
