我知道这将是一个重复。但我已经尽力解决它,一切都是徒劳的。我什至无法填充一个简单的网格面板!!!显然我是 extjs 的新手。
我的js代码如下:
Ext.onReady(function(){
var store = new Ext.data.JsonStore({
url: 'compare.php',
fields: ['name', 'area']
});
store.load();
var grid = new Ext.grid.GridPanel({
store: store,
columns: [
{header: 'Name', width: 100, sortable: true, dataIndex: 'name'},
{header: 'Position', width: 100, sortable: true, dataIndex: 'area'}
],
stripeRows: true,
height:250,
width:500,
title:'DB Grid'
});
grid.render('db-grid');
});
我的php如下:
<html>
<head>
</head>
<body bgcolor="white">
<?php
$link = pg_Connect('host=my_host port=5432 dbname=da_name user=postgres password=my_password');
$sql = "SELECT name, area FROM \"TABLE\" LIMIT 10";
if (!$link) {
echo "error";
} else {
$result = pg_query($link, $sql);
$rows = array();
$totaldata = pg_num_rows($result);
while($r = pg_fetch_assoc($result)) {
$rows[] = $r;
}
//echo json_encode($rows);
//echo json_encode(array('country' => $rows));
echo '({"total":"'.$totaldata.'","country":'.json_encode($rows).'})';
}
?>
</body>
</html>
我的json如下:
[
{
"total": "10",
"country": [
{
"name": "CULTIV",
"area": "1.10584619505971e-006"
},
{
"name": "CULTIV",
"area": "2.87818068045453e-006"
},
{
"name": "CULTIV",
"area": "6.96120082466223e-007"
},
{
"name": "CULTIV",
"area": "1.17171452984621e-007"
},
{
"name": "CULTIV",
"area": "1.25584028864978e-006"
},
{
"name": "CULTIV",
"area": "5.86309965910914e-007"
},
{
"name": "CULTIV",
"area": "4.12220742873615e-007"
},
{
"name": "CULTIV",
"area": "7.59690840368421e-006"
},
{
"name": "CULTIV",
"area": "2.47360731009394e-007"
},
{
"name": "CULTIV",
"area": "4.04940848284241e-005"
}
]
我需要为此设置任何代理吗?实际上,我的应用程序运行在与我的数据库不同的服务器上。
