删除div节点的子节点 [英] Deleting child nodes of a div node

问题描述

我有以下代码来删除div节点的子节点.这两个代码都正确吗?

I have following codes to remove child nodes of a div node. Are both of these codes correct?

while(innerWindowContentBox.hasChildNodes())     
innerWindowContentBox.removeChild(innerWindowContentBox.childNodes[0]);

其他是

innerWindowContentBox.innerHTML = '';

请注意，该代码用于Greasemonkey脚本，因此不需要IE支持.

Note that the code is for a Greasemonkey script so IE support is not required.

推荐答案

向

Added another test case to the jsPerf benchmark posted by @Brock Adams. It is slightly faster to test using element.firstChild (at least in Chrome):

while (containerNode.firstChild ) {
    containerNode.removeChild (containerNode.childNodes[0] );
}
