How to greayout back button and view source of browser - javascript

How do u greayout backbutton or view source of browser so users can't click backbutton and view source code because javascript contains lot of business logic code. I need to greayout those options so users can't be able to click them. i recently joined banking project and i am beginner in java and development.

Try adding this in the Head section of your html file:
<script type="text/javascript">
window.history.forward();
function noGoingBack() {
window.history.forward();
}
</script>
And add this in your Body section:
<body onload="noGoingBack();" onpageshow="if (event.persisted) noBack();" onunload="">
This prevents the page from going back.

Using Cordova webview

I wish to find out, for mobile developing using Cordova, is there a way to open a remote web app, and when a button is click in the remote web app, it execute a java script in Cordova environment?
For example, my mobile app opened up a web page hosted in the app server through web view, to ask the user to acknowledge he read and accept the license. The user need to click "Accept" or "Not Accept" on the web page.
If the user click "Accept", I hope to run a javascript that can bring up another page in the mobile app for the user to proceed to use the mobile app.
Is this possible?
Thanks!
Firstly, it's not a good idea to have a mobile app that is totally reliant on a remote server in order to function properly: what if the user's internet connection cuts out or is intermittent? (that happens plenty where I live).
However, one solution would be use an iframe to load the remote webapp content and cross-frame messaging to communicate the outcome of the UI interactions with the remote webapp back to your Cordova app. You will have to appropriately whitelist your remote webapp URL.
Something like this:
Cordova app index.html
<html>
<head>
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript">
function onDeviceReady(){
window.addEventListener("message", onFrameMessage, false);
}
function onFrameMessage(event){
var eventName = event.data[0];
if(eventName === "terms_result"){
var accepted = event.data[1] == 1; // == will match 1 or "1"
if(accepted){
// Do something - e.g. change to homepage
}else{
// Do something else - e.g. display an error message
}
}
}
document.addEventListener("deviceready", onDeviceReady);
</script>
</head>
<body>
<div data-role="page" id="terms">
<iframe src="http://example.com/my/remote/webapp" style="border: 0; width: 100%; height: 100%"></iframe>
</div>
<div data-role="page" id="home">
<!-- Your home page content -->
</div>
</body>
</html>
Remote webapp html
<html>
<head>
<script type="text/javascript">
function accept(result){
window.parent.postMessage(["terms_result", result], "*");
}
</script>
</head>
<body>
<button onclick="accept(1)">Accept</button>
<button onclick="accept(0)">Not Accept</button>
</body>
</html>

Insert javascript widget on one page of Drupal site

I have a javascript widget that can be inserted on an a plain-old html page like this:
<html>
<head>
<script type='text/javascript' src="http://example.com/widget.js"></script>
</head>
<body>
<script type='text/javascript'>
//<![CDATA[
try{ widget_constructor('key',500,400); }
catch(e){ alert(e.message); }
//]]>
</script>
</body>
</html>
I would like to insert this javascript on one page of a Drupal 6 site (not every page).
This is what I have tried so far to get the script tag in the HEAD:
I set the Full HTML input format to allow php.
For the Drupal page, I set the input format to Full HTML
I then added this to the top of the body of my Drupal page:
<?php
drupal_set_html_head('<script type="text/javascript" src="http://example.com/widget.js"> </script>');
?>
But Drupal doesn't parse the php and instead prints this at the top of the page:
<?php drupal_set_html_head(''); ?>
Any suggestions as to how I can do this?
#Jeff: You should not really reconsider that. Using the PHP Filter is generally a bad idea as it potentially opens security holes. (In case someone would gain access to your user account or you have a misconfiguration in your settings this is a direct path to compromising the whole server)
I would rather propose to add js via the template.php of your theme. Also the right method to use is drupal_add_js with the option inline:
http://api.drupal.org/api/drupal/includes--common.inc/function/drupal_add_js/6
Here are some further reads on how to use it:
http://drupal.org/node/304178#comment-1000798 http://drupal.org/node/482542
I'm not too familiar with Drupal so this answer merely gets around your widget not loading without actually answering the question why that PHP block isn't being parsed as PHP.
You don't need to call the <script> tag inside the <head>. You can just place that line right above the <script> tag that calls the widget constructor.
<html>
<head>
</head>
<body>
<script type='text/javascript' src="http://example.com/widget.js"></script>
<script type='text/javascript'>
//<![CDATA[
try{ widget_constructor('key',500,400); }
catch(e){ alert(e.message); }
//]]>
</script>
</body>
</html>
After writing that all out, I figured out the problem...
The full html input format has an HTML corrector filter turned on by default, and that filter appears to have caused problems with the PHP code. Reordering the filters to put the PHP evaluator first fixed the problem.

how to close popup using javascript with xml formatting

I bought this program that created a pretty nice imageuploader flash script however I can't get the Javascript function close window to close the popup and redirect the original page.
here is the XML piece that defines the url's:
<urls urlToUpload="upload.php?" urlOnUploadSuccess="http://www.home.com/purchase.html"
urlOnUploadFail="http://www.home.com/tryagain.html"
urlUpdateFlashPlayer="http://www.home.com/flashalternative.html"
jsFunctionNameOnUpload=""/>
This last line calls a javascript function on upload. The problem is I don't know what to call and where to put it.
Here is the HTML file that is the popup:
<HEAD>
<title>Baublet Uploader</title>
<script type="text/javascript" src="swfobject.js"></script>
</HEAD>
<BODY>
<!-- Q-ImageUploader www.quadroland.com -->
<div id="QImageUploader">
Flash Player stuff here
</div>
<script type="text/javascript">
// <![CDATA[
var so = new SWFObject("q_image_uploader.swf", "imageuploader", "650", "430", "9", "#FFFFFF");
so.addParam("scale", "noscale");
so.addParam("salign", "TL");
so.addVariable("AdditionalStringVariable","pass additional data here");
so.write("QImageUploader");
// ]]>
</script>
I found this Closing script I thought might work:
<script language="javascript">
function close_window(page) {
window.opener.location.href=page
setTimeout(function(){window.close()},10);
}
</script>
Does this go into the Popup HTML page above or would it be a separate close.js file in the root?
Thanks,
I'm really confused.
It looks like that bit of script belongs to the popup. It changes the parent window's location and then closes itself after a ~10ms delay. The function close_window most likely is being called by the Flash applet.

Why does fb:fan control disappear after login with requireSession on external page?

Reqs:
I want to make an external page with a 'Become a Fan'-button.
I want users to login to facebook once they open the page (this is because of other features in the site)
So I call FB.Connect.requireSession once the page loads, and put a <fb:fan></fb:fan> control on the page.
Then when I open the page I see the 'Connect with Facebook to Continue' pop-up and a small 'Become a fan' button. This seems right. When I log in to Facebook using the pop-up the 'Become a fan button' disappears!!
Can anyone explain this weird behaviour or does someone know a way to reach my requirements in a different way.
Below you can see my code.
Thanks in advance!
<!-- Head -->
<script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/nl_NL" type="text/javascript"></script>
<script type="text/javascript">
var fbApiKey = "MY_KEY";
var fbXdReceiver = "xd_receiver.htm";
function fbLoad() {
FB.init(fbApiKey, fbXdReceiver);
FB.ensureInit(function() {
FB.Connect.requireSession(null, null, false);
});
}
</script>
<!-- Body onload="fbLoad();" -->
<fb:fan profile_id="24932281961" name="Nutella" id="fanButton" stream="0" connections="0" logobar="0" width="250"></fb:fan>
I solved this by making the page refresh after a successful login
So I call requireSession with a callback
FB.ensureInit(function() {
FB.Connect.requireSession(requireSessionSuccess, null, false);
});
And this is the code for the callback
function requireSessionSuccess() {
window.open('default.aspx?fbloggedin=true', '_self');
}
