Windows phone 8 Phonegap和Windows Phone 7:IndexOutOfBoundsException

我在将phonegap应用程序从Android和iOS移动到WP8时遇到问题。当我尝试加载一些language.JSON文件时，它似乎崩溃了。我使用的版本是PhoneGap2.9.0和jQuery 2.0.3。在Android和iOS上，一切都按预期运行

控制台输出：

这是语言文件的ajax加载：

 var _loadDataSet = function(callback) {
        $.ajax({url: "localization/" + _language + ".json", async: false, dataType: 'json', success: function(data) {
            _dataSet = data;
            if(callback) {
                callback();
            }
        }}).error(function(e) {
            console.error("Error in language files.");
            console.error(e);
        });
    };

我不知道从哪里开始，任何帮助都将不胜感激

请显示您对文件代码的读取

我使用Mustach模板引擎制作应用程序，并执行了以下操作：

$.Mustache.load("./templates/about/about-app.tpl")

此未加载，因为WP8要求完整路径：

$.Mustache.load("www/templates/about/about-app.tpl")

顺便说一下，WP7-不使用完整路径加载，只使用relative=））

还有一件事：

$.ajax({url: "www/localization/" + _language + ".json", async: false, dataType: 'json', success: function(data) {

WP项目不喜欢json等扩展（有时它确实有效，有时不知道为什么），所以我建议您：

1） 将文件类型更改为*.txt

2） 请求：

更新：

$.ajax({url: "www/localization/" + _language + ".json", async: false, dataType: 'json', success: function(data) {

差点忘了，要使用AJAX，您必须执行以下操作：

document.addEventListener('deviceready', function() {
    jQuery.support.cors = true;
    $.mobile.allowCrossDomainPages = true;
}, false);

解决方案是使用XMLHttpRequest。在Android、iPhone和Windows Phone 8上测试并运行。虽然加载本地语言文件的解决方案是将数据添加到JavaScript类，但WP8上PhoneGap的跨域请求仍然存在问题

为了在WP8上实现跨域请求，我使用了XMLHttpRequests（也可以使用JSONP，但它还支持其他格式）。这是我最终使用的包装器类：

(function() {
    name.of.package.HTTPRequest = function(destination, success, error, contentType) {
        var STATUS_IDLE = 0;
        var STATUS_OPEN = 1;
        var STATUS_LOADED = 2;
        var STATUS_WORKING = 3;
        var STATUS_DONE = 4;

        var req = new XMLHttpRequest();
        req.open('GET', destination, true);

        if(contentType) {
            req.setRequestHeader("Content-Type", contentType);
        }
        else {
            req.setRequestHeader('X-Requested-With', 'XMLHttpRequest');
        }

        req.onreadystatechange = function(aEvt) {
            if(req.readyState == STATUS_DONE) {
                if(req.status == 200) {
                    if(success) {
                        success(req.responseText);
                    }
                }
                else {
                    if(error) {
                        error("Response returned with error code: " + req.status);
                    }
                }
            }
        };

        req.send(null);
    };
}) ();

尝试将文件重命名为.txt，不幸的是没有更改。还使用早期版本的jquery进行了检查，但未成功。请再次更新我的答案
