Question

我在具有离线功能的网络应用程序中有一个javascript / jquery功能，可以在Chrome 11中运行良好，但由于Chrome 12已经停止运行。不关心其他浏览器，但在更新版本的Chrome中使用它变得越来越重要。

简而言之，我调用一个PHP数据页（不是跨域）并返回一个JSON数组，该数组被迭代，将响应元素插入到本地SQLite数据库中。

控制台日志不会引发任何标记，也不会出现javascript错误。我在响应中看到了JSON，而且似乎中断的唯一部分是try块中的数据插入。

任何人都知道版本11之后的Chrome是否会发生变化，这会阻止与SQLite数据库的交互？任何帮助都将非常感激。

function importAssignmentData() 
{
var import_count = 0;
$.get("data.php", function(data) {
    if (data instanceof Array){
        // Data is properly formed as an array.
    }
    else{
        alert('Data from the server was not properly formed. You may not be logged in.');
    }
    $.each(data, function(index, value) { 
        if (this.order_id == 'authfail'){
            alert("You are not logged into the server. Authentication failure.");
            console.log("Authentication failure.");
        }
        else{
            if (typeof this.order_id != 'undefined') { // sanity check    
                import_count++;
                var EMPTY               = "";
                var order_id            = (this.order_id == '') ? EMPTY : this.order_id;

结果证明这与jQuery 1.5.2有些不兼容。不确定涉及的内部或细节，但此时我甚至不关心。

升级到jQuery 1.6.4库解决了这个问题。

我现在要梳理一下我留下的小头发 - 希望这会帮助其他人留下更多的头发。

Web应用程序SQLite插件在Chrome 11中运行良好，自版本12以来就失败了。
