函数通过循环迭代，一次又一次，但是再也不会起作用
|
我正在调用Titanium模式窗口，然后运行一个循环遍历某些数据的函数；
视窗1：
var win = Ti.UI.createWindow({
url: \'window2.js\'
modal: 1
});
win.open();
win = Ti.UI.currentWindow;
function doLoop() {
Ti.API.info(\'doLoop fn called\');
// I\'ve tracked the issue down to here
var m = 0;
for(var i in list) { m++; }
Ti.API.info(m);
Ti.API.info(\'finished\');
}
win.addEventListener(\'open\', function() {
// list is dynamically generated and passed through successfully from window1.js
doLoop();
});
function buildMediaItemsSelectionTable() {
var mediaCount = 0, i;
for(i in mediaItemsSelectionList[0]) { mediaCount++; }
for(i=0,l=mediaCount;i<l;i++) {
addMediaItemsSelectionSongsRow(i);
}
}
没有找到相关结果

函数存在的问题 您的for..in循环可能会捕获您没有的对象属性 不需要双循环 这是适当的修改function buildMediaItemsSelectionTable() { var i = 0, p; for ( p in mediaItemsSelectionList[0] ) { if ( mediaItemsSelectionList[0].hasOwnProperty( p ) ) { addMediaItemsSelectionSongsRow( i++ ); } } }var win = Ti.UI.createWindow({ url: \'window2.js\' , modal: 1 , list: [1,2,3] });var button = Ti.UI.createButton( {title: \'Modal\'} ); Ti.UI.currentWindow.add( button ); button.addEventListener( \'click\', function() { win.open(); });var win = Ti.UI.createWindow({ url: \'window2.js\' , modal: 1 , list: randomList() }); var button = Ti.UI.createButton( {title: \'Modal\'} ); Ti.UI.currentWindow.add( button ); button.addEventListener( \'click\', function() { win.open(); }); function randomList() { // Random return an array with 3, 5, or 7 items return [[1,2,3],[1,2,3,4,5],[1,2,3,4,5,6,7]][Math.floor(Math.random()*2)]; }button.addEventListener( \'click\', function() { win.list = randomList(); win.open(); });呕蹿尉
function doLoop() { Ti.API.info(\'doLoop fn called\'); // I\'ve tracked the issue down to here var m = 0; for(var i in list) { m++; Ti.API.info(m); Ti.API.info(\'finished\'); }
