getScriptArgs: function() { //获取多个参数 var
scripts = document.getElementsByTagName("script"), script = scripts[scripts.length - 1], //因为当前dom加载时后面的script标签还未加载，所以最后一个就是当前的script src = script.src, reg = /(?:\?|&)(.*?)=(.*?)(?=&|$)/g, temp, res = {}; res["src"] = src; while
((temp = reg.exec(src)) != null) res[temp[1]] = decodeURIComponent(temp[2]); return
res; } |
二、根据名字获取Hash值

function
getQueryString(name) { var
reg = new
RegExp("(^|&)"
+ name + "=([^&]*)(&|$)", "i"); var
r = window.location.hash.substr(1).match(reg); if
(r != null) return
r[2]; return
null;} |
