【问题描述】:
我正在尝试使用 Appcelerator 将 JSON 文件放入 JavaScript 中的表中,但我不太确定为什么在编译到示例页面时它会输出为空表。我对处理 JavaScript 和 JSON 格式都比较陌生,所以如果您发现任何愚蠢的逻辑或语法错误,请放轻松,并告诉我如何解决我的问题:
// Set the background color with no windows or tabs
Titanium.UI.setBackgroundColor('#000');
// Create the window
var win1 = Titanium.UI.createWindow({
title:'Challenge Window',
backgroundColor:'#fff',
});
// Store the image and its properties
var image = Titanium.UI.createImageView({
image: "https://myavantiservices.files.wordpress.com/2015/02/helloworld.gif",
height: 380,
width: 380,
center: 512,
top: -50
});
var tableData;
// Parse our JSON file using onload
var url = "https://www.sitepoint.com/twitter-json-example/";
var json;
var xhr = Ti.Network.createHTTPClient({
onload: function() {
json = JSON.parse(this.responseText);
tableData = json;
}
});
// Create the table and insert the JSON data
var table = Titanium.UI.createTableView({
data: tableData,
height: 480,
width: 480,
top: 256,
left: 232
});
// Add the image to the window and open the window
win1.add(image);
win1.add(table);
win1.open();
url返回的JSON:
{"results":[

【问题讨论】:
-
不,编译时没有控制台错误。
-
不是在编译时,我的意思是在浏览器的开发者工具中:)
-
哦,对不起。不,Chrome 中也没有错误。
