导航current背景

========================================简单一点的

var locationUrl = location.href.toLowerCase();

//导航current
$("#nav li").each(function () {
var $this = $(this);
var navUrl = $this.find("a").attr("href").toLowerCase();

if (locationUrl.indexOf(navUrl) > -1 && navUrl != "/") {
$("#nav li").removeClass("current");
$this.addClass("current");
}
});

---------------------------找工作频道

$("#nav li").each(function () {
var $this = $(this);
var navUrl = $this.find("a").attr("href").toLowerCase();

if (locationUrl.indexOf(navUrl) > -1 && navUrl != "/") {
$("#nav li").removeClass("current");
$this.addClass("current");
}
if (locationUrl.indexOf("/jianzhishixi") > -1 && navUrl.indexOf("/jianzhishixi") > -1) {
$("#nav li").removeClass("current");
$this.addClass("current");
}
if (locationUrl.indexOf("/ll") > -1 && navUrl.indexOf("/ll") > -1) {
$("#nav li").removeClass("current");
$this.addClass("current");
}
});

========================================以下复杂一点

$(document).ready(function () {
var mainNavPage = ["Index.aspx", "Map.aspx", "Recruitment.aspx", "Traffic.aspx", "Enterprise.aspx", "JobSeekers.aspx", "ContactUs.aspx"];
function getMainNavPageIndex() {
var currPageUrl = location.href.toLowerCase();
for (var i = 0; i < mainNavPage.length; i++) {
if (i == 2) {
var scene = mainNavPage[i].split('|');
for (var j = 0; j < scene.length; j++) {
if (currPageUrl.indexOf(scene[j].toLowerCase()) != -1) {
return i;
}
}
}
else if (currPageUrl.indexOf(mainNavPage[i].toLowerCase()) != -1) {
if ((i == 0 && currPageUrl.match(/\//g).length == 3) || i > 0) {
return i;
} else {
continue;
}
}
}
return -1;
}
var currMainNavPageIndex = getMainNavPageIndex();
if (currMainNavPageIndex != -1) {
$("#nav li").removeClass("current");
$("#nav li").eq(currMainNavPageIndex).addClass("current");
}
});
