一些js函数工具类(以后或者会用到)

1.sleep()

function sleep(numberMillis) {        var now = new Date();       var exitTime = now.getTime() + numberMillis;         while (true) {            now = new Date();            if (now.getTime() > exitTime)    return;        }}

作用是跟setTimeout一样的，都是等待多少毫秒执行。numberMillis表示多少毫秒

?

2.removeHTMLTag()

 function removeHTMLTag(str) {            str = str.replace(/<\/?[^>]*>/g,''); //去除HTML tag            str = str.replace(/[ | ]*\n/g,'\n'); //去除行尾空白            str = str.replace(/\n[\s| | ]*\r/g,'\n'); //去除多余空行            str=str.replace(/ /ig,'');//去掉             return str; }

去除html标签。str为要去掉的字符串
