It is a simple bug which I observed.
Issue: google chrome find functionality does not work properly.

Steps to follow:
1. Load some url for eg www.mcafee.com
2. ctrl+F (find) and search for word “mcafee” you will observe the successful find results.
3. Now press F5 and refresh the page. Once the page is loaded, you will find that find control will be still open. 
4. Now click on the find control without clearing the mcafee word and try pressing Enter.
It will not show the find result.

Expected result: It should show the find result
Actual result: does not shows the find result

Collection of Data on….

Usability Is all about:

  • Effectiveness
    (Can user achive what they need by using the product?)
  • Ease of learning
    (How fast can a user who has never seen the interfact can learn to use it?)
  • Efficency of use
    (How fast can a user compete his tasks?)
  • Error Prevention
    (The best way to deal with errors is to design Interfact in such way that user do not make errors)
  • Memorability
    (Can user remember enough to reuse the User Interface effectively?)
  • Satisfaction
    (How much does the user like to using the system?)

“Usability” refers to the extent which a user can use the interface to achieve his specified goals with effectiveness, effeicency and satisfation.

Usability can be achived by Human centered design :
The active involovment of user and a clear understanding of user and task requirement.
An appropriate allocation of function between user and technology.

onload is javascript event.

Purpose : To call any action while the page is rendered.

Still lot of people are not aware about when the onload funtion is called.

Lot of  people  thing  as onload can be specified in the <body> tag as soon as the body tag is rendered in the html , the on load will called for  its action.

But that is not the case onload will only be called at last when the whole page is rendered.

Copy past the below HTML  and test it baby. 

<html>
<head>
 <script>
  function ping() {alert(“Hellow world!!!”)}
 </script>
</head>
<body onload=”ping()”><h1>Bookstore</h1><ul>
 <script>
  alert(“alert inside the body”)
 </script>
something
</body>
</html>
