我正在使用這一位代碼插入並從數據庫中選擇文本。我怎樣才能實現這個圖像,而不是文字。我已經完成了我的谷歌分享(ing)我找不到任何幫助。數據庫插入圖像,而不是文本
var index_count = 0
var up_check = 0
function get_db(a, up_check) {
var db = LocalStorage.openDatabaseSync("DB5", "1.0", "The Example QML SQL!", 1000000);
db.transaction(
function(tx) {
tx.executeSql('CREATE TABLE IF NOT EXISTS Greeting(salutation TEXT, salutee TEXT)');
for (var z=0; z<1000; z++){
tx.executeSql('INSERT INTO Greeting VALUES(?, ?)', [ 'Movie', z ]);
}
var rs = tx.executeSql('SELECT * FROM Greeting');
var r = ""
for(var i = 0; i < a; i++) {
if (i>index_count-1 && up_check ===0)
r += rs.rows.item(i).salutation + ": " + rs.rows.item(i).salutee + "\t\t"
if (up_check === 1){
var size_check =0
if (i >index_count-11 && size_check !==9) {
r += rs.rows.item(i).salutation + ": " + rs.rows.item(i).salutee + "\t\t"
size_check++
}
}
}
console.log(r);
index_count=a;
return r;
})}
這是什麼都與MySQL呢? –
