ternary: var message =(confirm("submit?"))? "You selected OK": "You selected cancel"; alert(message); But the best I like in your videos, whenever I have a question, your answer is in the next video. :)

[@naveenjami8221]

HI Venkat, your videos are very nice to learn and understand. your explanantion with examples is simply super. Thanks you so much. please update 2 or 3 videos per day if possible. It will be helpful to us.

[@flifluflofli]

sorry I dont undertsand when you do the confirmation function where the confirm is from IF ( confirm ("are you confirming ? ") {}) thanks to clarify

[@shrutilengure4188]

tnq sr.your videos are good one to easily explain the example,learn and understanding.,.

Hello Venkat, But at the beginning of the page loading, if we press the Tab key, these events will not happen as expected?

[@sabarishchandramouli6418]

Thanks for your videos Venkat. At 11:43, you are passing a controlID parameter and then using it in the document.getelement(ControlID). Can you please let me know which element in the DOM has the ID - ControlID.

[@lifet4800]

COntrolID is a parameter passed from input text box , that is txtLastname

[@taruchitgoyal3735]

Hi If I have a form in html, and I want to perform validation in text field, without repeatedly calling the function written in script for each text field. Rather the validation function should get executed on its own whenever the user tries to type on any of the text field. Can this be achieved?

[@birkhansonkan4236]

Why make a variable "control" if you can use directly the id of an element in your script? So: var control= document.getElementById("btn"); control.style.background="red"; instead of this you can use: btn.style.background="red"; The last option also works but why dont they use the second option? Is there something wrong with this method ?

[@alanwong202]

Birkhan Sonkan you misunderstand. document.getElementById("btn") means: from this document get me a element with an id of 'btn' and assign it to the variable which I'd like to name as 'control'. In your case btn.style.background cannot be used as 'btn' is a variable which has not been declared yet. However the user could have done var btn= document.getElementById("btn"); //notice variable name is called 'btn' btn.style.background="red"; However naming your javascript variables the same as HTML/CSS id's or classes is not good as it can become confusing

[@aj90271]

+Birkhan Sonkan Hey it doesn't look like the other people directly answered your question. It IS possible to do it like you've shown, but from what I've read online, it is considered bad practice. Take a look at this page from stack overflow: stackoverflow.com/questions/7826737/directly-reference-html-elements

[@birkhansonkan4236]

+Alex Jordan Thanks man after a lot of Tutorials online i now understand the difference between DOM and Javascript so the answer is the difference between these two. The one is a JavaScript selection the other is a DOM selection method so im getting better and better by day. :) Thanks for the reference.

[@jiturcm1]

nice

[@drcvagos-iu]

well done, sir :)

[@bitsnnbytes]

excellent

[@drcvagos-iu]

congratulations

[@mahipalkamanchi]

thank u sir...!

[@reassume4826]

i didn't get why we needed a argument over there?? why didn't we use id name in get by id??

[@birabir8595]

in this example theres two so in order to receive id of both, argument is used

[@vladvira5271]

At least i know how much means JQuery now!

[@filiplahoda248]

looks more like an event in HTML

[@sidhantsingh1648]

Control ID is just a variable used inside the function.....whichever ID he is validating he will pass that ID while calling the function and that value will be copied in ControlID...
