晚上好， 我是QooxDoo的初學者，我試圖通過將我的一些HTML，JavaScript和CGI工作轉換成qx來學習它。這些不是生產應用/頁面/表格，沒有人使用它們，它們唯一的目的是改善和娛樂我。
在將我的一箇舊的示例HTML FORM轉換爲QX解決方案時，我得到了Qooxdoo Documentation（QooxDoo附帶的pdf）不足以解釋或幫助我嘗試去做的事情。我希望社區能通過一個例子或指示解釋來幫助我理解這一點。如何將qooxdoo表單提交給cgi腳本進行處理？
下面是示例HTML表單：
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title></title>
</head>
<body>
<br />
<form action="webformprocess.cgi" method="POST">
Town/City:<input name="fTown" size="30" /> <br />
Your name:<input name="fName" size="20" value="John" />
<font size="-1"><i>Yes, this field comes with a default value.</i></font><br />
<br />
<fieldset>
<legend>Pick a colour:</legend>
<input name="fColour" type="radio" value="red" />red<br />
<input name="fColour" type="radio" value="white" />white<br />
<input name="fColour" type="radio" value="green" />green<br />
</fieldset>
<br />
<fieldset>
<legend>What transportation do you like?</legend>
<input name="fTransport" type="checkbox" value="car" />car<br />
<input name="fTransport" type="checkbox" value="tram" />tram<br />
<input name="fTransport" type="checkbox" value="bycicle" />bycicle<br />
</fieldset>
<br />
<input type="submit" label="Mehet..." />
</form>
<br />
</body>
</html>
這裏是示例Perl CGI腳本處理表單：
#!/usr/bin/perl
use strict;
use POSIX qw(strftime);
use CGI ':standard';
use CGI::Carp qw(fatalsToBrowser);
my $form_town = param('fTown');
unless (defined $form_town) { $form_town = 'WAS UNDEFINED'; }
my $form_name = param('fName');
unless (defined $form_name) { $form_name = 'WAS UNDEFINED'; }
my $form_colour = param('fColour');
unless (defined $form_colour) { $form_colour = 'WAS UNDEFINED'; }
my $form_transport = param('fTransport');
unless (defined $form_transport) { $form_transport = 'WAS UNDEFINED'; }
print "Content-type: text/html\n\n";
print "<pre>\n";
print "<p> town = $form_town .</p>\n";
print "<p> name = $form_name .</p>\n";
print "<p> colour = $form_colour .</p>\n";
print "<p> transport = $form_transport .</p>\n";
print "</pre>\n";
最後，這裏是多遠我將HTML表單轉換爲QooxDoo：
/**
* This is the main application class of your custom application "urlap_qx"
*/
qx.Class.define("urlap_qx.Application",
{
extend : qx.application.Standalone,
/*
*****************************************************************************
MEMBERS
*****************************************************************************
*/
members :
{
/**
* This method contains the initial application code and gets called
* during startup of the application
*
* @lint ignoreDeprecated(alert)
*/
main : function()
{
// Call super class
this.base(arguments);
// Enable logging in debug variant
if (qx.core.Environment.get("qx.debug"))
{
// support native logging capabilities, e.g. Firebug for Firefox
qx.log.appender.Native;
// support additional cross-browser console. Press F7 to toggle visibility
qx.log.appender.Console;
}
/*
-------------------------------------------------------------------------
Below is your actual application code...
-------------------------------------------------------------------------
*/
// Create a form named "urlap".
var urlap = new qx.ui.form.Form();
//Basic input fields without headline.
var fTown = new qx.ui.form.TextField("Bristol,UK");
urlap.add(fTown, "Town/City");
var fName = new qx.ui.form.TextField();
urlap.add(fName, "Your name");
// Radio buttons.
urlap.addGroupHeader("Pick a colour:");
var fColour1 = new qx.ui.form.RadioButton();
var fColour2 = new qx.ui.form.RadioButton();
var fColour3 = new qx.ui.form.RadioButton();
urlap.add(fColour1, "Red");
urlap.add(fColour2, "White");
urlap.add(fColour3, "Green");
new qx.ui.form.RadioGroup(fColour1, fColour2, fColour3);
// Checkboxes.
urlap.addGroupHeader("What transportation do you like?");
var fTransport1 = new qx.ui.form.CheckBox();
var fTransport2 = new qx.ui.form.CheckBox();
var fTransport3 = new qx.ui.form.CheckBox();
urlap.add(fTransport1, "car");
urlap.add(fTransport2, "tram");
urlap.add(fTransport3, "bycicle");
var sendButt = new qx.ui.form.Button("Submit");
sendButt.addListener("execute", function() {
if (urlap.validate()) {
alert("This is where it was supposed to send data to my CGI-script for processing...");
}
}, this);
urlap.addButton(sendButt);
this.getRoot().add(new qx.ui.form.renderer.Single(urlap), {left: 10, top: 10});
} // end_main()
} // end_members:
}); // end_qx_class_define
我的麻煩是，我無法弄清楚如何發送qx表單數據到我的perl cgi進行處理。即，從HTML表單複製<form action="webformprocess.cgi" method="POST">行的功能。我已經閱讀了關於表單驗證和序列化以及同步和異步方法和模型以及綁定的幾個小時，但是這些並不包括我正在尋找的內容。我還認爲，我正在尋找錯誤的東西，而不是將該表單提交給我的CGI腳本，這應該以完全不同的方式完成。
任何人都瞭解這個話題，請給我一個正確的方向！
更改/更新＃1
var sendButt = new qx.ui.form.Button("Submit");
sendButt.addListener("execute", function() {
if (urlap.validate()) {
//alert("Attempting to POST the Form ...");
var vezerlo = new qx.data.controller.Form(null, urlap);
var adatmodell = vezerlo.createModel();
var parameterek = qx.util.Serializer.toUriParameter(adatmodell);
var igeny = new qx.io.request.Xhr("http://my.websrv.tld/folder/webformprocess.cgi");
igeny.setMethod("POST");
igeny.setRequestData(parameterek);
// Listeners to give feedback...
igeny.addListener("success", function() {
alert("Request succeeded.");
}, this);
igeny.send();
alert("Send complete.");
}
}, this);
urlap.addButton(sendButt);
你或許應該寫一個東西，你實際上已經嘗試和失敗（假設你不只是閱讀它），這樣人們可以考慮這一點。 OTOH，你可以將你的示例代碼歸結爲只需一個文本字段和一個提交按鈕，就可以獲得理解問題所需的代碼。 – ThomasH
採取了點。我應該確實簡化了示例代碼。事實上，我甚至只有兩個字段的基本版本，我應該用它作爲例子。另一個教訓！ ;-) – Keve
