jquery ajax没有在android上返回数据

Question

我有一个jQuery Ajax函数，可以从json数据创建多个链接列表。它适用于所有Web浏览器IE，FF，Safari，Chrome，Opera，适用于iPhone，iTouch和iPad。出于某种原因，它无法在Android上运行：

function FetchListsMobTest(thislist) {
    var thislist;
    if (thislist == "comp") {
        $('<div id="wrapper"></div>').html('<div id="comp1"><div id="companies"></div></div>').appendTo("#firstlist");
    } if (thislist == "prod") {
        $('<div id="wrapper"></div>').html('<div id="prod1"><div id="products"></div></div>').appendTo("#secondlist");
    } if (thislist == "stan") {
        $('<div id="wrapper"></div>').html('<div id="stan1"><div id="standards"></div></div>').appendTo("#thirdlist");
    } if (thislist == "cert") {
        $('<div id="wrapper"></div>').html('<div id="cert1"><div id="certified"></div></div>').appendTo("#fourthlist");
    }
    var Params = {};
    Params.type = "get",
    Params.url = "javascript/directories.js",
    Params.data = "data",
    Params.dataType = "json",
    Params.cache = false,
    Params.contentType = "application/json",
    Params.processData = true,
    Params.callbackParameter = "callback",
    Params.error = function (xhr, textStatus, errorThrown) { alert(xhr.errorThrown); },
    Params.success = function (data) {
        $.each(data.directory, function (i, data) {
            var Company2 = '' + data.Company + '';
            var Product2 = '' + data.Product + '';
            var Standard2 = '' + data.Standard + '';
            var Certify2 = '' + data.Certified + '';
            if (thislist == "comp") {
                $('<div class="company" style="text-align:left;border-bottom: 1px solid #ccc;margin: 0px;padding-top: 0.5em;padding-left: 0.4em;padding-right: 0px;padding-bottom: 0.5em;font-size: 0.9em;line-height: 100%;"></div>').html('<a href="listingsMob.html?Company=' + Company2 + '" target="_top" style="text-decoration: none;padding-left: 10px;background-image: url(images/open_arrow.gif);background-position: bottom left;background-repeat: no-repeat;">' + Company2 + '</a>').appendTo("#companies");
            } if (thislist == "prod") {
                $('<div class="product" style="text-align:left;border-bottom: 1px solid #ccc;margin: 0px;padding-top: 0.5em;padding-left: 0.4em;padding-right: 0px;padding-bottom: 0.5em;font-size: 0.9em;line-height: 90%;"></div>').html('<a href="listingsMob.html?Product=' + Product2 + '" target="_top" style="text-decoration: none;padding-left: 10px;background-image: url(images/open_arrow.gif);background-position: bottom left;background-repeat: no-repeat;">' + Product2 + '</a>').appendTo("#products");
            } if (thislist == "stan") {
                $('<div class="standard" style="text-align:left;border-bottom: 1px solid #ccc;margin: 0px;padding-top: 0.5em;padding-left: 0.4em;padding-right: 0px;padding-bottom: 0.5em;font-size: 0.9em;line-height: 90%;"></div>').html('<a href="listingsMob.html?Standard=' + Standard2 + '" target="_top" style="text-decoration: none;padding-left: 10px;background-image: url(images/open_arrow.gif);background-position: bottom left;background-repeat: no-repeat;">' + Standard2 + '</a>').appendTo("#standards");
            } if (thislist == "cert") {
                $('<div class="certify" style="text-align:left;border-bottom: 1px solid #ccc;margin: 0px;padding-top: 0.5em;padding-left: 0.4em;padding-right: 0px;padding-bottom: 0.5em;font-size: 0.9em;line-height: 90%;"></div>').html('<a href="listingsMob.html?Certified=' + Certify2 + '" target="_top" style="text-decoration: none;padding-left: 10px;background-image: url(images/open_arrow.gif);background-position: bottom left;background-repeat: no-repeat;">' + Certify2 + '</a>').appendTo("#certified");
            }
        });
        // because this is in a for each loop, it may list the returned variables multiple times so
        // remove duplicate returned variable appearances
        var mapAddedComany = {};
        //alert('comes here');
        $(".company").each(function () {
            var value = $(this).text();
            if (mapAddedComany[value] == null) {
                mapAddedComany[value] = true;
            } else {
                $(this).remove();
            }
        });
        var mapAddedProduct = {};
        $(".product").each(function () {
            var value = $(this).text();
            if (mapAddedProduct[value] == null) {
                mapAddedProduct[value] = true;
            } else {
                $(this).remove();
            }
        });
        var mapAddedStandard = {};
        $(".standard").each(function () {
            var value = $(this).text();
            if (mapAddedStandard[value] == null) {
                mapAddedStandard[value] = true;
            } else {
                $(this).remove();
            }
        });
        var mapAddedCertify = {};
        $(".certify").each(function () {
            var value = $(this).text();
            if (mapAddedCertify[value] == null) {
                mapAddedCertify[value] = true;
            } else {
                $(this).remove();
            }
        });
        return false;
    },
    $.ajax(Params);
}

我一直在搜索论坛两天，无法弄清楚我做错了什么。任何帮助将不胜感激。
