HTML Buttons and JavaScript

sutharshan — Tue, 19 Oct 2010 05:55:17 +0000

Multiple html buttons within single HTML label

When placing multiple html buttons within single html label, the following issue was found. Especially when using with the JavaScript functions for both buttons. The following code demonstrates the problem clearly. This example uses JQuery library

HTML code

< !DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd">
 xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">

  http-equiv="Content-type" content="text/html; charset=utf-8" />
 </span></a></span>Div Drag/Resize Demo<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">
   src="js/jquery.min.js">
 type="text/javascript">
 
$().ready(init);
function init(){
$('#txtinsert').click(function(){alert("button1")});
$('#display').click(function (){alert("button2")});
$('#display1').click(function (){alert("button3")});
}




 name="txtinsert" type="button" id="txtinsert" value="Insert Test"  />
 name="display" type="button" id="display" value="display" />
 name="display1" type="button" id="display1" value="display1" />

In the above program the expected results are follows.

When the user clicks the button1 the message box displays with the message button1
When the user clicks the button2 the message box displays with the message button2
When the user clicks the button3 the message box displays with the message button3

But the real results that will be obtain from the above program are follows

When the user clicks the button1 the message box displays with the message button1
When the user clicks the button2 the message box displays with the message button2 and followed by another message box with the message button1
When the user clicks the button3 the message box displays with the message button3 and followed by another message box with the message button1

This problem occurs because all the buttons were placed within a single label tag and because of that if the buttons except the first is pressed, it triggers the event of the clicked button and also triggers the click event for the first button.

If you come across this kind of issue, remove the label tags and once its removed these behaviors will not be observed.

Wondershare time freeze

sutharshan — Wed, 25 Aug 2010 09:10:28 +0000

Wondershare offers lots of desktop and mobile products to the industry and for home use. When I visited their website I found about their vision and about the company. Their vision is "The software wisdom shared worldwide." and their mission is to be a global leading consumer software developer and publisher.

They offer varieties of products in the following categories. By following those links you can simply view the products from their website and download the trial version to test those applications.

One of the product that make me interested in wondershare is time freeze. Well actually its a PC Utility software that they provide to protect the PC from malware and virus attacks and to prevent the lose of data. I have downloaded that product and tested with my computer and found its very handy and I didn't experience any processing delays in using this product. Even though there was a slight delay during the start up and afterwards it works fine for me. Of course I'm using Core 2 Duo 2GHz processor with 4gb ram.

Wondershare Time Freeze is a virtual system software, and easier to use. In their website they have given as it utilizing advanced virtualization technology and it can provide higher-level security to computer, enhance MBR protection, and greatly improve the efficiency of virtual system. As a End user I while using this software I have installed several games and some other small freeware and shareware softwares to test on the system. Those worked fine and once the system rebooted, there were no signs of installations of those software. Well its actually a virtual system and those softwares were installed in the virtual system itself. Therefore once its rebooted there were no applications.

It also provides folder protection which can be used to protect specific folders as i guess. I haven't tried those features yet much. but I hope that's how it actually works and these are the key features of the wondershare time freeze software which they have mentioned in their website.

Create a better system condition

Combination of virtual system program and antivirus software works perfectly to guarantee your system safety;
Eliminate costs of frequent disk defragmentation.

Make your system safe from viruses

Test suspicious software and game installations safely on the virtual system;
Watch online movies and surf internet freely without fear of virus attack.

Enhance your system protection

Offer more flexibility to roll system back to the state before protection, or save virtual system data to the real system;
Support protecting MBR and ensure computer to boot up normally.

As you can see it provides lots of benefits where as I have tested few of them with the trial version of this software. I have reinstalled my operating system and other softwares several times mainly due to testing the new softwares and games. Its a headache and when it comes to company environment its important to keep the computer safe from the threat attacks. Therefore my opinion is to have a software like this to protect the real system from the attacks and its actually serves its purpose well.

My one and only worry is that, there were several softwares which needs the reboot to work properly. when I test those softwares with this time freeze, they wont work at all. Because i need to restart the system in order to make those softwares work. But when I reboot, everything those stored in the virtual system has been gone. Except this everything else was perfectly fine with this software. I like to test the Time shuttle, but the main issue is that to test such application I have to use that for several months.

Here is the link to download the product: http://www.disk-utilities.com/time-freeze/

I recommend all to have a look at that application and see how it works to you and give me your feedbacks.

Confirmation using JavaScript

sutharshan — Fri, 30 Jul 2010 17:58:03 +0000

While I'm looking through the websites I have seen several websites are using server side scripting such as php,asp.net, jsp etc to get the confirmation from the users previous action.

I'll make it clear with a small example...

When a user wants to delete a post, the user clicks on the delete button or link that performs the delete operation. Once he clicked usually the most best appropriate manner is to get confirm from the user whether he really wants to delete the post or he clicked that mistakenly. Because if he have clicked it mistakenly then the post will be deleted and its more inconvenience for the user. Therefore for such critical operations confirmation must be taken from the user before performing the action.

Now we'll move to the topic. I have seen several websites using server side scripting to get the confirmation from the users. its actually takes more time, since the server scripts alone will reload the page from the server to produce the confirmation dialog. Which is actually a time consuming work for users and also in the developers point of view, the coding and designing is also time consuming. Therefore what i feel is the best way is to use JavaScript...

The following code demonstrates how to create the confirmation using JavaScript

For links

Delete

For Buttons

What really happens in the above JavaScript codes?

In the both examples we have used "onclick" event handler, which actually triggers when we click the link or button which even contains that handler.

The most important think is that, HTML hyper-links starts to work (navigate) when the mouse released and not in the mouse click. You can simply observe this behavior by click on the hyperlink and drag the mouse pointer out of the hyperlink without releasing and release it outside the hyperlink. if you do like this, the hyperlink wont work. simply because it works only on release. The same concept is applicable for the form elements also.

Now we'll go back to the example. the event handler "onclick" triggers when the mouse button is pressed and then it calls the JavaScript confirmation dialog box.

In That the user can use either OK or Cancel. If the user clicks OK button, it returns true and if the user clicks cancel it returns false. When it returns true the click event will be active and because of that, the mouse release event will be performed and the required action will happen. But if it returns false, the button or the link click event will not be recognized and therefore no actions will be performed. In other words, if it returns false, then for the browser, the user doesn't have click the link/button.

Therefore by adding a small piece of JavaScript code, we can get the confirmation from the users, rather than using server side languages which takes time to load.

Another version of JavaScript code added for advance users

add this code inside tag
