如何将frm php转换为c＃或json（extjs） [英] how can i convert frm php to c# or json (extjs)
问题描述
我正在使用浏览器 - 布局我的应用程序示例
i am using the browser-layout example for my application
我试图添加一个两棵树给它
这里尝试做的是定义在一个单独的文件中的twotrees，我的主要文件是layout-browser.js，我需要在我拥有的选项卡中添加（和其他）。请自觉地问我其他问题，如果它不是clair，请裸露我真的新的所有这一切，不能得到它
what im trying to do here is define the twotrees in a separate file, my main file is the layout-browser.js and i need to add this (and others) in the tabs i have in it . feel free to ask me other questions if its not clair and please bare with me im really new to all this and cant get hold of it
问题是im使用.net，该例子正在使用php
所以我该如何使用.net
so how can i make this work in .net
这是我的代码：
Ext.require（['*']）;
Ext.require(['*']);
var store = Ext.create('Ext.data.TreeStore', {
proxy: {
type: 'ajax',
url: 'get-nodes.php'
},
root: {
text: 'Ext JS',
id: 'src',
expanded: true
},
folderSort: true,
sorters: [{
property: 'text',
direction: 'ASC'
}]
});
var tree = Ext.create('Ext.tree.Panel', {
id: 'tree',
store: store,
width: 250,
height: 300,
columnWidth: 0.5,
viewConfig: {
plugins: {
ptype: 'treeviewdragdrop',
appendOnly: true
}
}
// ,renderTo: document.body
});
var store2 = Ext.create('Ext.data.TreeStore', {
proxy: {
type: 'ajax',
url: 'get-nodes.php'
},
root: {
text: 'Custom Ext JS',
id: 'src',
expanded: true,
children: []
},
folderSort: true,
sorters: [{
property: 'text',
direction: 'ASC'
}]
});
var tree2 = Ext.create('Ext.tree.Panel', {
id: 'tree2',
width: 250,
height: 300,
columnWidth: 0.5,
store: store2,
viewConfig: {
plugins: {
ptype: 'treeviewdragdrop',
appendOnly: true
}
}
// ,renderTo: document.body
});
Ext.define("Ext.app.myTwoTrees",{
extend:"Ext.panel.Panel",
width : 600,
height: 350,
layout: 'column',
items: [
tree , tree2
]
});
我在我的标签中调用它这样
i call it in my tab like this
Ext.create('Ext.app.myTwotrees')
这里是get-nodes.php
here is the get-nodes.php
<?php
// from php manual page
function formatBytes($val, $digits = 3, $mode = 'SI', $bB = 'B'){ //$mode == 'SI'|'IEC', $bB == 'b'|'B'
$si = array('', 'K', 'M', 'G', 'T', 'P', 'E', 'Z', 'Y');
$iec = array('', 'Ki', 'Mi', 'Gi', 'Ti', 'Pi', 'Ei', 'Zi', 'Yi');
switch(strtoupper($mode)) {
case 'SI' : $factor = 1000; $symbols = $si; break;
case 'IEC' : $factor = 1024; $symbols = $iec; break;
default : $factor = 1000; $symbols = $si; break;
}
switch($bB) {
case 'b' : $val *= 8; break;
default : $bB = 'B'; break;
}
for($i=0;$i<count($symbols)-1 && $val>=$factor;$i++)
$val /= $factor;
$p = strpos($val, '.');
if($p !== false && $p > $digits) $val = round($val);
elseif($p !== false) $val = round($val, $digits-$p);
return round($val, $digits) . ' ' . $symbols[$i] . $bB;
}
// grab the custom params
$path = isset($_REQUEST['path'])&&$_REQUEST['path'] == 'extjs' ? '../../../' : '../../';
$node = isset($_REQUEST['node']) ? $_REQUEST['node'] : '';
$isXml = isset($_REQUEST['isXml']);
if(strpos($node, '..') !== false){
die('Nice try buddy.');
}
$nodes = array();
$directory = $path.$node;
if (is_dir($directory)){
$d = dir($directory);
while($f = $d->read()){
if($f == '.' || $f == '..' || substr($f, 0, 1) == '.') continue;
$filename = $directory . '/' . $f;
date_default_timezone_set('America/Los_Angeles');
$lastmod = date('M j, Y, g:i a', filemtime($filename));
if(is_dir($directory.'/'.$f)){
$qtip = 'Type: Folder<br />Last Modified: '.$lastmod;
$nodes[] = array(
'text' => $f,
'id' => $node.'/'.$f,
'cls' => 'folder'
);
} else {
$size = formatBytes(filesize($filename), 2);
$qtip = 'Type: JavaScript File<br />Last Modified: '.$lastmod.'<br />Size: '.$size;
$nodes[] = array(
'text' => $f,
'id' => $node.'/'.$f,
'leaf' => true,
'cls' => 'file'
);
}
}
$d->close();
}
if ($isXml) {
$xmlDoc = new DOMDocument();
$root = $xmlDoc->appendChild($xmlDoc->createElement("nodes"));
foreach ($nodes as $node) {
$xmlNode = $root->appendChild($xmlDoc->createElement("node"));
$xmlNode->appendChild($xmlDoc->createElement("text", $node['text']));
$xmlNode->appendChild($xmlDoc->createElement("id", $node['id']));
$xmlNode->appendChild($xmlDoc->createElement("cls", $node['cls']));
$xmlNode->appendChild($xmlDoc->createElement("leaf", isset($node['leaf'])));
}
header("Content-Type: text/xml");
$xmlDoc->formatOutput = true;
echo $xmlDoc->saveXml();
} else {
echo json_encode($nodes);
}
感谢很多
推荐答案
我建议您将问题分解成两部分：
I would recommend you break the problem into two pieces:
1）更改 url： get-nodes.php'到 url：'my-dotnet-url ，使.NET页面返回静态JSON或XML（硬编码值到树上）
1) change url: 'get-nodes.php' to url: 'my-dotnet-url and make the .NET page return static JSON or XML (hardcode the values to the tree)
这将确认您的所有javascript，资源等都正常工作，而您只是问.NET如何输出某些数据。
That will confirm all your javascript, resources, etc. is working properly and that you are only asking a .NET question about how to output certain data.
2）然后找到一个.NET示例，让您从无论何时获取数据创建JSON或XML（我猜测可能是一个数据库）。您只需要输出看起来像您的静态数据正常工作。如果您不太了解PHP或.NET学习.NET以使输出正确，将比尝试移植该示例更容易。如果你卡住了，我会转发一个不同的问题，并询问如何动态地输出静态文件产生的数据，并且没有涉及到extjs的复杂程序！
2) Then find a .NET example that will let you create JSON or XML from wherever you are getting data (I'm guessing probably a database). You just need the output to look like your static data that worked correctly. If you don't know much PHP or .NET learning .NET to get your output correct would be easier than trying to port over that example. If you get stuck, I'd repost a different question and ask how to output the data that results from that static file dynamically and don't have the extjs complication involved!
希望这有帮助。
