根据url的属性名来取属性值赋值给js

<script> ???var status= getUrlAttribute(‘status‘); ???if(null!=status) ???{ ???????alert(status); ???} ???function getUrlParam(name) { ???????var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)"); ???????var r = window.location.search.substr(1).match(reg); ???????if(r != null) { ???????????return unescape(r[2]); ???????} ???????return null; ???}</script>

function getUrlParam(parameName){ ???//location.search是从当前URL的?号开始的字符串，即查询字符串 ???var query = (location.search.length > 0 ? location.search.substring(1) : null); ???if(null!=query) ???{ ???????var args = new Object( ); ???????var pairs = query.split("&"); ????????for(var i = 0; i < pairs.length; i++) ????????{ ???????????var pos = pairs[i].indexOf("="); ????????????if (pos == -1) ????????????????continue; ????????????var argname = pairs[i].substring(0,pos); ????????????var value = pairs[i].substring(pos+1); ????????????value = decodeURIComponent(value); ????????????args[argname] = value; ????????} ???????//根据键名获取值 ???????return args[parameName]; ????} ???return null;}
