从URL中提取参数的实用函数解析

方便获取url中参数的函数

function getQueryStringArgs() {var qs &＃61; (location.search.length > 0 ? location.search.substring(1) : &＃39;&＃39;),args &＃61; [],items &＃61; qs.length ? qs.split(&＃39;&&＃39;) : [],item &＃61; null,name &＃61; null,value &＃61; null,i &＃61; 0,len &＃61; items.length;for (i&＃61;0; i i&＃43;&＃43;) {item &＃61; items[i].split(&＃39;&＃61;&＃39;);name &＃61; decodeURIComponent(item[0]);value &＃61; decodeURIComponent(item[1]);if (name.length) {args[name] &＃61; value;}}return args;
}

以数组的形式返回

获取URL指定参数

function getOption(key) {if (window.location) {var search &＃61; location.search;if (search &＃61;&＃61; "") {return "";}search &＃61; search.slice(1);var searchArr &＃61; search.split("&");var length_1 &＃61; searchArr.length;for (var i &＃61; 0; i var str &＃61; searchArr[i];var arr &＃61; str.split("&＃61;");if (arr[0] &＃61;&＃61; key) {return arr[1];}}}return "";}
