js删除特定节点

直接上代码

function clear(){var head = document.getElementsByTagName('head')[0].children;for(var i=0;i<head.length; i++){if(head[i].innerHTML){if(head[i].innerHTML.indexOf("NREUM") > 0){document.getElementsByTagName("head")[0].removeChild(head[i]);}}}var body = document.getElementsByTagName('body')[0].children;for(var j=0;j<body.length; j++){if(body[j].innerHTML){if(body[j].innerHTML.indexOf("NREUM") > 0){document.getElementsByTagName("body")[0].removeChild(body[j]);}}}}setTimeout(clear,5000);

寻找head和body中含有NERUM在节点，并删除
