我尝试用 phonegap 创建一个本地数据库。但是当我尝试执行我的程序时,我得到了这个错误: sqlite 返回:错误代码 = 1,msg = 3 列的 4 个值,db=/data/data/com.wilder.phonegap/databases/webview.db 错误处理 SQL : 5 at file:///android_asset/www/js/script.js:61 这是我创建数据库的脚本代码,后跟 index.html 文件我想创建一个由用户填写的表单,然后在列表视图中列出它提前感谢您帮助我。
function onLoad(){
// Wait for PhoneGap to load
document.addEventListener("deviceready", onDeviceReady, false);
}
// PhoneGap is ready
function onDeviceReady() {
var db = window.openDatabase("Database", "1.0", "Database", 200000);
var submitBtn = $("#submit");
submitBtn.click(function(){
db.transaction(populateDB, errorCB, successCB);
});
}
// Populate the database
function populateDB(u) {
var setNom = $("#nom");
var setRace = $("#race");
var setCouleur = $("#couleur");
u.executeSql('DROP TABLE IF EXISTS ADOPTER');
u.executeSql('CREATE TABLE IF NOT EXISTS ADOPTER (nom, race, couleur)');
u.executeSql('INSERT INTO ADOPTER (nom, race, couleur) VALUES ("' + setNom.val() + '", "' + setRace.val() + '", "' + setCouleur.val() + '", "' + '")');
}
// Query the database
function queryDB(u) {
u.executeSql('SELECT * FROM ADOPTER', [], querySuccess, errorCB);
}
// Query the success callback
function querySuccess(u, results) {
var len = results.rows.length;
console.log("ADOPTER table: " + len + " rows found.");
for (var i=0; i<len; i++){
var getNom = results.rows.item(i).nom;
var getRace = results.rows.item(i).race;
var getCouleur = results.rows.item(i).couleur;
var nom = $(".nom");
var race = $(".race");
var couleur = $(".couleur");
nom.replaceWith("<p>" + getNom + "</p>");
race.replaceWith("<p>" + getRace + "</p>");
couleur.replaceWith("<p>" + getCouleur + "</p>");
console.log("Row = " + i + " NOM = " + results.rows.item(i).nom + " RACE = " + results.rows.item(i).race + " COULEUR = " + results.rows.item(i).couleur);
}
}
// Transaction error callback
function errorCB(err) {
console.log("Error processing SQL: "+err.code);
}
// Transaction success callback
function successCB() {
var db = window.openDatabase("Database", "1.0", "Database", 200000);
db.transaction(queryDB, errorCB);
}
