javascript - 隐藏/显示内容时 jQuery 意外延迟

Question

当您访问特定 URL 时，会加载初始内容，然后解释 URL 参数，然后内容会发生变化。

在我的本地计算机上，这种情况发生“快速 split ”，也就是快到你看不到任何延迟。但是，如果您在大约 5 秒后访问该 URL，内容最终会隐藏并显示正确的内容。下面是 js，这是一个非常接近的小 html 片段。

示例网址:www.example.com/page1.aspx?nav=2012?id=113&pid=2

HTML:

  <div id="default">content</div>   
  <div id="mobile2012" style="display:none;">content</div>

Javascript:

var querystring = location.search.replace('?', '').split('?');
var queryObj = {};
for (var i = 0; i < querystring.length; i++) {
    var name = querystring[i].split('=')[0];
    var value = querystring[i].split('=')[1];

    queryObj[name] = value;
}
////////
var subNavDestination = queryObj["nav"];
////////
urlParams(subNavDestination);
function urlParams(subNavDestination) {
    var displayInformation;

    switch (subNavDestination) {
        case 'about': displayInformation = "AboutEarthquakeIns";
            break;
        case 'homeowner': displayInformation = "Homeowner2012Content";
            break;
        case 'renter': displayInformation = "Renter2012Content";
            break;
        case 'mobilehome': displayInformation = "Mobilehome2012Content";
            break;
        case 'condo': displayInformation = "Condominium2012Content";
            break;
        case '2011': displayInformation = "pdf2011";
            break;
        case '2012': displayInformation = "pdf2012";
            break;
        default: displayInformation = "GeneralContent";
    }

    if (displayInformation != "AboutEarthquakeIns") {
        //$('#PolicyTypes2012 .sideNavPolicyType').slideToggle();
        $('#PolicyTypes2011 .sideNavCoverage').slideUp();
    }

    if (displayInformation == "pdf2011") {
        controlContentVisibility("pdf2011");
        $('#PolicyTypes2011 .sideNavPolicyType').slideToggle();
        $('#PolicyTypes2011 .sideNavCoverage').slideUp();
        setActiveLink();
        setSelectedPolicyType();
        hideYearSubMenus(2012);
    }
    else if (displayInformation == "pdf2012") {
        controlContentVisibility("pdf2012");
        $('#PolicyTypes2012 .sideNavPolicyType').slideToggle();
        $('#PolicyTypes2012 .sideNavCoverage').slideUp();
        setActiveLink();
        setSelectedPolicyType();
        hideYearSubMenus(2011);
    }

    controlContentVisibility(displayInformation);
}

当您点击 URL(我假设在远程站点)时，需要额外的时间来加载您将选择显示的 div 内容，然后才能解析/渲染它们。
