这是我的代码
var f = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory, 'mobile_db.js'); // Local File Read
Ti.include(f.nativePath);
var scrollView = Ti.UI.createScrollView({
contentWidth : 'auto',
contentHeight : 'auto',
showVerticalScrollIndicator : true,
showHorizontalScrollIndicator : false,
layout : 'vertical',
height : '100%',
width : '100%',
});
function sortObject(obj) {
var arr = [];
for (var prop in obj) {
if (obj.hasOwnProperty(prop)) {
arr.push({
'key' : prop,
'value' : obj[prop]
});
}
}
arr.sort(function(a, b) {
return a.value - b.value;
});
return arr;
}
var arr = sortObject(data);
var lblArr = [];
var roctje = [];
var alertDialog = Titanium.UI.createAlertDialog({
title: 'ffs error?',
message: 'Do you want to do this?',
buttonNames: ['Yes','Sparta?','No'],
cancel: 1
});
for (var i = 0; i < 20; i++) {
if (data[i].instelling_title == "ROC") {
roctje.push(data[i].instelling_title);
}
else if (data[i].instelling_title == "Scalda") {
alertDialog.show();
}
else {
alertDialog.show();
}
lblArr[i] = Ti.UI.createLabel({
text : roctje[i] + ' ' + ' - ' + ' ' + ' ' + ' ' + adresArray[i].address_street + ' ' + adresArray[i].address_housenr + ' ' + adresArray[i].address_postalcode + ' ' + adresArray[i].address_city + ' ' + adresArray[i].address_country,
color : 'black',
top : '15',
width : '85%'
});
scrollView.add(lblArr[i]);
}
var viewqq = Ti.UI.createView({
borderRadius : 10,
top : 10,
height : 2000,
width : 'auto'
});
Ti.UI.currentWindow.add(viewqq);
scrollView.add(viewqq);
Ti.UI.currentWindow.add(scrollView);
Ti.UI.currentWindow.add(viewqq);
我要推送的阵列:
var data = [
{item: 'SCALDA 1', instelling_title: 'Scalda', instelling_desc: ''},
{item: '14', instelling_title: 'Scalda', instelling_desc: ''},
{item: '15', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '16', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '17', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '18', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '19', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: 'ROC22', instelling_title: 'ROC', instelling_desc: ''},
{instelling_id: '21', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '22', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '13', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '12', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '3', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '4', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '5', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '6', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '799', instelling_title: 'ROC', instelling_desc: ''},
{instelling_id: '8', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '9', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '10', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '11', instelling_title: 'Scalda', instelling_desc: ''},
{instelling_id: '23', instelling_title: 'Scalda', instelling_desc: ''}
];
当我从数组中加载数据(roctje)时,它会在应用程序内部说是Undifined。我的猜测是阵列是空的,但不确定。任何人都可以帮助我:p? 提前致谢
答案 0 :(得分:0)
从问题中不确定,但从观察中我可以看到在for循环中你使用data
作为数组而不是arr
这是数组。
data
是您传递给arr
的对象。
