這裏有很多代碼,但問題與底部的for循環有關。是否不必循環執行executeSql命令的結果?
var dbo = openDatabase('xxx','1.0','myDatabase', 1048576);
var DropTableDeferred = new $.Deferred();
var CreateTableDeferred = new $.Deferred();
var InsertDeferred = new $.Deferred();
var SelectDeferred = new $.Deferred();
dbo.transaction(function(myTrans) {
myTrans.executeSql(
'drop table myTable;'
,[]
,DropTableDeferred.resolve()
);
});
DropTableDeferred.done(function() {
dbo.transaction(function(myTrans) {
myTrans.executeSql(
'CREATE TABLE IF NOT EXISTS myTable'
+ '(xxxID Integer NOT NULL PRIMARY KEY'
+ ',xxxName Varchar(128)'
+ ');'
,[]
,CreateTableDeferred.resolve()
);
});
});
CreateTableDeferred.done(function() {
dbo.transaction(function(myTrans) {
myTrans.executeSql("INSERT INTO myTable(xxxID,xxxName) VALUES(1,'A')");
myTrans.executeSql("INSERT INTO myTable(xxxID,xxxName) VALUES(2,'B')");
myTrans.executeSql(
"INSERT INTO myTable(xxxID,xxxName) VALUES(3,'C')",
[],
InsertDeferred.resolve()
);
});
});
InsertDeferred.done(function() {
dbo.transaction(function(myTrans) {
myTrans.executeSql(
'SELECT * FROM myTable',
[],
function(tx, result) {
SelectDeferred.resolve(result);
}
);
});
});
SelectDeferred.done(function(result) {
var X = $('#result-template').html();
var template = Handlebars.compile(X);
var data = [];
for(var i=0;i < result.rows.length; i++) {
data.push(result.rows.item(i));
}
$('ul').append(template(data));
});
Q:我需要爲了調用模板(數據),以建立一個數據陣列,或我可以直接傳遞結果變量?
而'結果變量',我的意思是:result.rows或result.rows.item,或其他組合。
哦,這個問題必須專門處理小鬍子和把手。我是否需要遍歷結果集才能構建鬍鬚可以使用的數組。 –
