JavaScript - Why to use "var that = this;"

Now a days most of JavaScript files are following Object Oriented Approach.

In simple words, it means it is possible to call super methods using child classes.

So not to lose a reference of function which is calling other one, that is smartly getting used.

Below are good examples explaining about that to refer this:

Using style.display instead of style.visibility

Hello,

HTML-CSS-JavaScript combination is little bit tricky to non-web developers.

There are few UIs which seems to be inconsistent as we are using JavaScript to enable/disable the HTML Components.

And it takes time to find out and align all the forms.

If you are using any JavaScript and CSS combination to hide/show any components, below information may save your time. 

To maintain proper alignment of whole HTML and its elements, please use following:

Element Property	Value
style.display	'none' (To hide element)
style.display	'' (Empty string to show element)

Please try to avoid using style.display='block' and style.visibility='hidden'/'visible'/'inline' as it is affecting the CSS applied.

Cheers and Enjoy Scripting!
