如何在HTML5中使用现有的sqlite数据库

Question

I have created an sqlite database file using sqlite browser.I have a file "sample.sqlite", now i wanted to know how to import this file in javascript and use the data in the sqlite file.I have been using this below mentioned script

var db;

try {
    if (window.openDatabase) {
        db = openDatabase("sample.sqlite", "1.0", "HTML5 Database API example", 200000);
        if (!db)
            alert("Error Failed to open the database, check version");
    } else
        alert("Error Not supported? Not gonna happen");
} catch(err) {}

By using this code i am not able to get the data from sqlite file.Please suggest me how to proceed.i have seen some sites where steps have been mentioned to create table,insert data by writing code in java script itself.But i don't know to do it that way i want to import the existing sqlite file.

Answer 1

Web apps are not allowed to access arbitrary files on the computer.

You could download some data from the same server where your JavaScript code comes from, but it would be easier and faster to embed the SQL commands to create your database in your code. (Use the .dump command of the sqlite3 command-line tool to get these SQL commands.)

Answer 2

for Safari browser:

create dummy database in your HTML5.

after that copy database file name from mentioned location.

\\Application Data\\Apple Computer\\Safari\\Databases{your domain name}{database File name}

replace your database file name from newer one. and paste into the above mentioned location.

open your HTML5 page i hope it's work's good.
