我已经使用 tabBar 创建了一个应用程序。我创建了一个单独的搜索窗口，其中包含一个 searchBar 和一个 TableView 来显示最近的搜索项。每当触发返回事件时，就会打开一个名为 searchresult.js 的新窗口，显示搜索到的数据。当我单击后退按钮时，它来自 searchresult.js-->searchpage.js，但问题是最近数据的表在数据库中得到了更新，但它没有显示在表上，我必须去主页并再次打开 searchpage.js 以查看正确的数据...请帮助...提前谢谢
我使用了以下代码：searchpage.js
//*** Search Field ***
var search = Titanium.UI.createSearchBar({
barColor:'#000',
showCancel:true,
height:43,
hintText:'Name of the part you want to search',
autocorrect:true,
top:0,
});
content.add(search);
//*** Table For Recent Search ***
var db = Titanium.Database.install('car.db','dbversion1');
var sql = db.execute ('SELECT * FROM search_history ORDER BY id DESC LIMIT 0, 10');
var data = [];
while (sql.isValidRow()){
var searchQuery = sql.fieldByName('search_query');
var selectedCategory = sql.fieldByName('selected_category');
var searchID = sql.fieldByName ('id');
data.push({title: searchQuery});
sql.next();
}
var searchTable = Titanium.UI.createTableView({
headerTitle:'RECENT SEARCH',
data: data,
});
Ti.API.info(searchTable.title);
content.add(searchTable);
//Search Action
search.addEventListener('blur', function(e) {
Titanium.API.info('search bar:blur received');
});
search.addEventListener('cancel', function(e) {
Titanium.API.info('search bar:cancel received');
search.blur();
});
search.addEventListener('return', function(e){
var insertSql = db.execute('INSERT INTO search_history (search_query, selected_category) VALUES ("' + search.value + '", 1)');
var win = Titanium.UI.createWindow({
backgroundColor:'#ffffff',
url:'searchresult.js',
title: 'Search Result',
searchValue: search.value
});
Ti.API.info(search.value);
search.blur();
Titanium.UI.currentTab.open(win, {animation:true});
});
// Back Button Action
bckButton.addEventListener('click', function(e){
if (Ti.Android){
win.close();
}else{
win.close({animated:true});
}
});
和 searchresult.js
// *** Content ***
var content = Titanium.UI.createView({
backgroundColor:'#fff',
height:'100%',
width:'100%',
layout:'vertical'
});
wrapper.add(content);
var searchQuery = win.searchValue;
var db = Titanium.Database.install('car.db', 'dbversion1');
var sql = db.execute ("SELECT * FROM part_category WHERE part_name LIKE \'%"+ searchQuery +"%\'");
var data = [];
while(sql.isValidRow()){
var partName = sql.fieldByName ('part_name');
var partID = sql.fieldByName ('id');
data.push({title: partName, hasChild:true, id:partID, url:'partsubcategory.js'});
sql.next()
};
var resultTable = Titanium.UI.createTableView({
data : data,
});
content.add(resultTable);
// Back Button Action
bckButton.addEventListener('click', function(e){
if (Ti.Android){
win.close();
}else{
win.close({animated:true});
}
});
