js 取得网址问号后面的参数(get 参数)

function getData() {

//处理get参数----------------------------

var strUrl = window.location.toString();

var getPara, ParaVal;

var aryPara = [];

if (strUrl.indexOf("?") != -1) {

var getSearch = strUrl.split("?");

getPara = getSearch[getSearch.length - 1].split("&");

for (var i = 0; i < getPara.length; i++) {

ParaVal = getPara[i].split("=");

aryPara[ParaVal[0]] = ParaVal[1];

}

}

//处理get参数 end------------------------

return aryPara;

}

getData会回传阵列方式的参数回来

var GET = getData();

console.log(GET['a']); //log会印出123
