Sencha Touch + Phonegap 应用程序的数据库

Question

您好，目前我在我的应用程序中的 Sencha Touch + Phonegap 中使用 LocalStorage，并从 WCF Rest 加载了超过 4000 条记录。在开发模式下我没有问题运行它在 Google Chrome 但是当我打包它并安装在 iOS8 设备时我的应用程序崩溃了。

以下是控制台中 localStorage 的总长度：

>JSON.stringify(localStorage).length
> 2917665

型号：

Ext.define("QualityAudit.model.DefectMatrix", {
    extend: "Ext.data.Model",
    config: {
        identifier: { type: 'uuid', isUnique: true },
        fields: [
                { name: "DefectMatrixID", type: "integer" },
                { name: "CustomerID", type: "integer" },
                { name: "CustomerName", type: "string" },
                { name: "DefectType", type: "integer" },
                { name: "DefectTypeName", type: "string" },
                { name: "Reference", type: "string" },
                { name: "Section", type: "string" },
                { name: "DefectDescription", type: "string" },
                { name: "SeverityID", type: "integer" },
                { name: "SeverityName", type: "string" },
                { name: "IsActive", type: "bool" },
                { name: "CreatedBy", type: "string" },
                { name: "CreatedDate", type: 'date', dateFormat: 'MS' }
        ]
    }
});

店铺：

 defectSync: function (counter, totRecords, callback) {
    var me = this;
    if (counter == undefined)
        counter = 0;


    //load defect matrix local local storage

    var defectsLocalStore = Ext.getStore('DefectMatrix');
    defectsLocalStore.load();

        var defectssurl = window.REST_DMGetListAllPaging + counter;
        QualityAudit.util.Proxy.doAjaxCall(defectssurl, '',
        function (response) {

            var data = Ext.JSON.decode(response.responseText); //encode Json List


            defectsLocalStore.load({
                callback: function (records, operation, success) {
                    Ext.Array.each(data, function (record) {
                        counter++;
                        record.dirty = true;
                        defectsLocalStore.add(record);
                        defectsLocalStore.sync();
                    });

                    console.log('DECFECT DATA AFTER SYNC: ' + defectsLocalStore.getData().length);

                    //Check if all records  loaded on local storage is equail to total defect rows then complete
                    if (defectsLocalStore.getData().length >= totRecords) {
                        console.log('defect loading successfull');
                        callback();
                    } else {
                        //Trigger again until condition is met
                        me.defectSync(counter, totRecords, callback);
                    }

                },
                scope: this
            });


        },
        function (response) {
            defectsLocalStore.load();
            callback(0);
        });

}

有人在您的项目中尝试过使用 webSQL 或 SQLlite 吗？我找不到任何好的样本。

非常感谢任何帮助和建议。

Answer 1

我几乎在每个项目中都使用 SQLite。恕我直言，最好的插件是 Cordova/PhoneGap SQLitePlugin.

你在页面上找到了一些示例，如何使用插件以及如何在 cordova 中使用 SQLite。

Answer 2

您可以将存储与代理一起使用：'sql'，它将使用 WebSQL 创建本地数据库。 sql proxy Doc
