js获取url中的参数且参数为中文时通过js解码

<a href="${pageContext.request.contextPath}/productdisplay/productDisplay_productDisplayUI.action?pkId=${pkId}&name=${name}" style="color:white; margin-top:10px; margin-bottom:10px;">${name}</a>

/** 初始化加载结束 */
function getUrlVars(){
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?')+1).split('&');
for(var i = 0; i < hashes.length; i++) {
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}

//获得所属分类的pkId
var params = getUrlVars();
//获得此中分类的id
var parentId = params[params[0]];
//获得分类的名称
var productName = decodeURI(params[params[1]]);
