Question

我正在尝试将数据插入到websql中。我在Chrome上测试它无法正常工作。我得到了error processing: SQL undefined。

以下是代码：

$(document).ready(function() {

var db = window.openDatabase("Database", "1.0", "News", 200000);
db.transaction(populateDB, errorCB, successCB);

//create table and insert some record
function populateDB(tx)
{
    tx.executeSql('CREATE TABLE IF NOT EXISTS news (id INTEGER PRIMARY KEY AUTOINCREMENT, title TEXT NOT NULL, description TEXT NOT NULL,link TEXT NOT NULL,category INT)');

    tx.executeSql('INSERT INTO news (title,descriptionlink,category) VALUES (?,?,?,?)',["test1","descrip","link2",2]);
}


// Transaction error callback
//
function errorCB(tx, err) {
    alert("Error processing SQL: "+err);
}

// Transaction success callback
//
function successCB() {
    alert("success!");
}});

使用PhoneGap和Cordova，您应该使用deviceready事件来完成您的工作。而不是“准备好文件”事件。

确保在这些代码之前包含了cordova.js文件。

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
   var db = window.openDatabase("Database", "1.0", "News", 200000);
   db.transaction(populateDB, errorCB, successCB);
}

//create table and insert some record
function populateDB(tx)
{
    tx.executeSql('CREATE TABLE IF NOT EXISTS news (id INTEGER PRIMARY KEY AUTOINCREMENT, title TEXT NOT NULL, description TEXT NOT NULL,link TEXT NOT NULL,categorie INT)');

    tx.executeSql('INSERT INTO news (title,descriptionlink,categorie) VALUES (?,?,?,?)',["test1","descrip","link2",2]);
}


// Transaction error callback
function errorCB(tx, err) {
    alert("Error processing SQL: "+err);
}

// Transaction success callback
//
function successCB() {
    alert("success!");
}});
