我正在尝试从 PHPMyAdmin 检索数据并尝试将数据显示到选择器更改中......这是我的代码 var currentWin = Ti.UI.currentWindow;
var sendit = Ti.Network.createHTTPClient();
sendit.open('GET', 'http://localhost/mobileapp/productread.php');
sendit.send();
sendit.onload = function(){
var json = JSON.parse(this.responseText);
var json = json.mobile_product;
var picker = Ti.UI.createPicker();
// turn on the selection indicator (off by default)
picker.selectionIndicator = true;
var data = [];
var pos;
data.push (Ti.UI.createPickerRow({title:''+ json[pos].product_name + '',custom_item:'b'}));
}
picker.add(data);
currentWin.add(picker);
//var rw = db.execute("SELECT product_name, SUM(product_quantity)FROM mobile_product GROUP BY product_name");
picker.addEventListener('change', function(e){
var sendit = Ti.Network.createHTTPClient();
sendit.open('GET', 'http://localhost/mobileapp/orderread.php');
sendit.send();
sendit.onload = function(){
var json = JSON.parse(this.responseText);
var json = json.mobile_product;
var pos;
var product_name = json[e.rowIndex];
for (pos=0; pos < json.length; pos++) {
alert(''+json[pos].orders + '');
}
}
})
}
在这里,当我更改选择器时,警报会显示列(订单)的所有值以进行一次更改...如果我将选择器更改为下一个,则警报会再次出现在列中的所有数据中。例如,如果我在列(顺序)中有 10 个值,并且如果我更改选择器值,则警报出现 10 次,有 10 个值。我想根据选择器中的更改显示列中的值... . 我已经从 PHPMyAdmin 中为选择器检索了数据(产品名称)...当我更改选择器时,我希望显示该特定名称的值....我正在使用查询 SELECT SUM(product_quantity) As orders FROM PHP文件中的mobile_product GROUP BY product_name ..我的PHP文件是
<?php
//cust-mysql-123-04
$link = mysql_connect('localhost', 'root', '');
if (!$link) {
die('Not connected : ' . mysql_error());
}
// make foo the current db
$db_selected = mysql_select_db('mobileapp', $link);
if (!$db_selected) {
die ('Can\'t use : ' . mysql_error());
}
// Set the default namespace to utf8
mysql_query("SET NAMES 'utf8'");
if($result = mysql_query("SELECT SUM(product_quantity) As orders FROM mobile_product GROUP BY product_name")) {
//echo mysql_num_rows($result);
while ($row=mysql_fetch_array($result)) {
// $json.= "<li>".$row['first_name']."</li>";
$json[]=array(
'orders'=>$row['orders']
);
}
}
echo json_encode(array( 'mobile_product' => $json ));
mysql_close();
?>
