[@anurag9953]

in some case u r using var = in funtions, and some cases u r direct getting to getelementbyid, no var is attached how to understand where to go ahead with var copy by vaLUE nd copy by referece part its confusing

[@priyadarshani4498]

Thank you soo much very helpful video

[@kripukhadka3387]

Great Video man

[@muskananand6494]

Sir how you can add "return" in form tag because "return" statement can only be used within a function body

[@prakashb1278]

I figured out an alternative which doesn't use return in Js function. Code below:
function validate() {
var uname = document.getElementsByTagName("input")[0].value.trim();
var pass = document.getElementsByTagName("input")[1].value.trim();
if(uname.length == 0 || pass.length == 0) {
alert("either of the input value is blank!");
}
else {
document.getElementsByTagName("form")[0].action = "welcome.html";
}
}

[@marky1756]

This is what I've looking for✅

[@javascriptdevelopers6458]

Good video, nicely explained.

[@eb4416]

Maybe the question will be answered in the following videos, but to be sure that I don't forget my question:
What if I just got the link to message.html, so the login-form is no obstacle for me as a user. If the user knows the link to the desired page, how do you prevent the access to that page and allow just someone to view it when he has the specific login data?

[@SimpleSnippets]

Pretty good question.Well this kinda falls into a little advance part of validation where this is kinda like a security feature. A simple way to handle this is to store username or a particular token id in the cookies and set it to null at the start and if you go onto this message.html link directly without going through the form, you check this cookie value onto the message.html page at the beginning. if it is null, it will mean you tried to access the message.html page directly without going through the form. if you go through the form page properly you set the username in the cookies to a proper value other than null so then you can load message.html properly. Hope you get the gist of this methodology ?

[@AnilYadav-qn3ch]

man you are osmm

[@swethav395]

Hi. I tried to use return statement in "form" tag.but it is showing error that it can be used only in fuction body.

[@bhavyasetty9005]
