My first APP, Cordova and iOS - html

I'm trying to do a simple APP with Phonegap (cordova 3.0.0) on iOS. Here is my index.html:
<!DOCTYPE html>
<head>
<title>APP</title>
<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8">
function onLoad() {
document.addEventListener("deviceready", onDeviceReady, false);
}
function onDeviceReady() {
alert("Hello!");
}
</script>
</head>
<body onload="onLoad()">
HOLA
<br />
PULSAME
<div id="idi"></div>
</body>
</html>
But nothing happens. My device never is ready, never shows the alert. I think the problem is the cordova.js, but I can't find the problem (the proyect was created fine and runs).
Any help?

Don't use your onLoad function to attach the listener. Instead just attach the listener, then use your onDeviceReady function as if it is the onLoad. It should look like this:
<!DOCTYPE html>
<head>
<title>SmartPol</title>
<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8">
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
alert("Hello!");
}
</script>
</head>
<body>
HOLA
<br />
PULSAME
<div id="idi"></div>
</body>
</html>
Also, if you want to attach any other event listeners then you can do so after onDeviceReady has fired.

Browser show blank page while using reactjs

Hi I am new in reactjs when i am running server.js file from terminal it show blank page on browser. The code of index.html file is:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<script src="https://cdnjs.cloudflare.com/ajax/babel-
core/5.8.23/browser.min.js"></script>
<script
src="https://cdnjs.cloudflare.com/ajax/libs/react/0.14.7/react.js">
</script>
<script
src="https://cdnjs.cloudflare.com/ajax/libs/react/0.14.7/react-
dom.js"></script>
</head>
<body>
<div id="app"></div>
<script type="text/babel">
ReactDOM.render(
<h1>Hello React!</h1>,
document.getElementById('app')
);
</script>
</body>
</html>
Thanks in advance.
This is a working example.
In your code, the wrong part is the CDN link to babel-core. You may always check your console when working with JS (on Google Chrome: Ctrl + shift + J on Windows, Cmd + Opt + J on IOS).
On the other hand, I thought this was a good opportunity to also introduce components (see ).
<!DOCTYPE html>
<html lang="en">

cannot add line of "row numbers" in textarea

I tried to add to textarea a line of the row numbers with this example:
http://alan.blog-city.com/jquerylinedtextarea.htm
this is my code and I allready use the css and js in my project:
<!DOCTYPE html>
<html>
<head>
<title>CODE</title>
<link href="jquery-linedtextarea.css" rel="stylesheet">
<script src="jquery-linedtextarea.js"></script>
</head>
<body>
<textarea class="lined" name="mytext"></textarea>
<script>
$(function () {
$(".lined").linedtextarea(
{ selectedLine: 1 }
);
$("mytext").linedtextarea();
});
</script>
</body>
</html>
what I wrong ?
It seems you forget to call Jquery Library...
Just add the code below on your <head>:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"> </script>
And I believe you should delete that part:
$("mytext").linedtextarea();
I've made a code. It works for me. Check it out...

<textarea class="lined" rows="10" cols="60">
JavaScript was originally developed by Brendan
Eich of Netscape under the name Mocha,
which was later renamed to LiveScript,
and finally to JavaScript.
The change of name from LiveScript to JavaScript roughly
coincided with Netscape adding support for
Java technology in its Netscape Navigator
web browser.

Polymer core-ajax why callback not work?

Here my code:
<!DOCTYPE html>
<html>
<head>
<script src="/client/polymer-0.5.2/bower_components/webcomponentsjs/webcomponents.min.js"></script>
<link href="/client/polymer-0.5.2/bower_components/polymer/polymer.html" rel="import">
<link href="/client/polymer-0.5.2/bower_components/core-ajax/core-ajax.html" rel="import">
</head>
<body>
<core-ajax id="directorInfoAjax" url="/main.ashx?action=directorInfo" handleAs="text" on-core-response="callback">
<script>
Polymer(
{
callback: function ()
{
var bp = this.response;
}
});
</script>
</core-ajax>
<script>
document.addEventListener('polymer-ready', function()
{
document.querySelector("#directorInfoAjax").go();
});
</script>
</body>
</html>
What wrong? Call back not fire.

As far as I know, you aren't using <core-ajax> as it should be used.
Here you have a working example for <core-ajax>:
<!doctype html>
<html>
<head>
<meta name="viewport" content="width=device-width, minimum-scale=1.0, initial-scale=1.0, user-scalable=yes">
<title>seed-element Demo</title>
<script src="https://www.polymer-project.org/components/webcomponentsjs/webcomponents.js"></script>
<link rel="import" href="https://www.polymer-project.org/components/polymer/polymer.html">
<link rel="import" href="https://www.polymer-project.org/components/core-elements/core-elements.html">
<link rel="import" href="https://www.polymer-project.org/components/paper-elements/paper-elements.html">
</head>
<body>
<core-ajax id="directorInfoAjax" url="http://echo.jsontest.com/key/value" handleAs="text" on-core-response="{{callback}}"></core-ajax>
<script>
document.addEventListener('polymer-ready', function() {
var ajax = document.querySelector("core-ajax");
ajax.addEventListener("core-response", function(e) {
alert("I received a response "+ this.response);
console.log(this.response);
}
);
ajax.go(); // Call its API methods.
});
</script>
</body>
</html>
In your code, the Polyymer declaration inside the component doesn't seem to work, and even if it worked, the callback function need to be wrapped in {{ }}.

I hope it helps, but if not, don't hesitate to ask for further information!
[EDIT] I wrote a simpler example
Check the below tutorial it might help you to figure out the issue:-

Incorporating External Html into a jQuery Mobile page

I am attempting to dynamically incorporate an external source of html into a jQuery mobile page. I am able to successfully incorporate the external html but it looks like regular HTML (i.e. not jQuery mobile affected Html). Can any one suggest what I might be doing wrong?
Main Html:
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.0-rc.1/jquery.mobile-1.1.0-rc.1.min.css"
/>
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://jqueryui.com/ui/jquery-1.7.1.js"></script>
<script src="http://code.jquery.com/mobile/1.1.0-rc.1/jquery.mobile-1.1.0-rc.1.min.js"></script>
<script>
$(document).ready(function () {
$("#main").load('externalHtml.html');
//$("#main").append('externalHtml.html');
//$("#main").load('externalHtml.html #contain');
//$("#main").page();
});
</script>
</head>
<body>
<div data-role="content">
<div id="main"></div>Main Page</div>
</body>
externalHtml.html:
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.0-rc.1/jquery.mobile-1.1.0-rc.1.min.css"/>
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://jqueryui.com/ui/jquery-1.7.1.js"></script>
<script src="http://code.jquery.com/mobile/1.1.0-rc.1/jquery.mobile-1.1.0-rc.1.min.js"></script>
</head>
<body>
external html
<div data-role="content" id="contain">
<input type="search" name="name" id="name" value="" />
</div>
</body>
</html>
If you .trigger('create') on the container element, jQuery Mobile will automatically initialize any widget within the container. For example:
$("#main").load('externalHtml.html').trigger('create');
They really should document this better, but if you look at the API events for each type of widget, you will see the documentation regarding the create event.
Also, read the top of this page of the documentation: http://jquerymobile.com/demos/1.1.1/docs/api/events.html
You should not be using document.ready and instead should be binding to the pageinit event for pseudo-pages. Using document.ready will most likely create headaches for you in the future.
-- UPDATE --
You will probably want to call .trigger('create') in a callback so the external HTML has loaded before you attempt to initialize it:
$("#main").load('externalHtml.html', function () {
$(this).trigger('create');
});

SAP UI5: object expected error in IE

i am using SAP UI5 and don't know why is it showing object expected in line 347 while running index.html file in ie.
<html>
<head>
<meta content="IE=edge" http-equiv="X-UA-Compatible">
<script src="resources/sap-ui-core.js"
type="text/javascript"
id="sap-ui-bootstrap"
data-sap-ui-libs="sap.ui.commons,sap.ui.ux3"
data-sap-ui-theme="sap_goldreflection" >
</script>
<script type="text/javascript" src="OPM_CM.js"></script>
<script>
sap.ui.localResources("opm");
var view = sap.ui.view({id:"OPM_CM1", viewName:"opm.OPM_CM", type:sap.ui.core.mvc.ViewType.JS});
//view.placeAt("content");
buildShell();
</script>
</head>
<body class="sapUiBody" role="application">
<div id="content"></div>
</body>
</html>
thanks in advance.
This may be happening because the sap object is not available.
<script>
function init(){
sap.ui.localResources("opm");
var view = sap.ui.view({id:"OPM_CM1", viewName:"opm.OPM_CM", type:sap.ui.core.mvc.ViewType.JS});
//view.placeAt("content");
buildShell();
}
window.addEventListener('load',init);
</script>
adding your code to a function and calling it on body onload may do the trick.
Note: please also give more details about the error you are getting.
