Answer 1

Hi Harsh Kishore
Here is your fixed code
https://code.sololearn.com/Wf1dFmjL1WXg/?ref=app
2 things:
1 .value is used to get value from input tags
2. .textContent = is used to set value of text in p tags

Also did you want to add one to the value of #abc? Because i added that to

Answer 2

p elements have no 'value' properties (only input/form fields have one)... for most of elements you should assign the 'textContent' property ;) (or innerHTML if you want to replace html code)

Answer 3

as you get value as string you should convert it to number to avoid string concanetation:

Number(string_value)+1

Answer 4

as you use value or textContent: by assigning an html string wich will be parsed on the fly to update the page/element content ;)

Answer 5

say you want assign to paragraph a string with a line break:

document.getElementById("def").innerHTML = "Hello<br>World";

Answer 6

search in Q&A: this question has been posted a lot of time ^^

Answer 7

what case?

Answer 8

Hi Harsh Kishore
Just added a parseInt to convert the value of x to an integer. It should work now

Answer 9

parseInt() converts the value in the parentheses to an integer if possible. So if you had the string “43” and passed it into the parseInt() function it would convert it from a string to an integer and allow you to use mathematical operations such as + or - on it

Also #abc refers to the input tag as it’s id is abc and the # is used to reprent id in css

Answer 10

Harsh Kishore first you must distinguish between assignement operator (=) and comparison operator (==)...

then you make an if..else statement as:

if (x==1) {
htmlElementReference.textContent = "true";
}
else {
htmlElementReference.textContent = "false";
}

Answer 11

document.getElementById("abc").innerHTML = parseInt(x) + 1;

Answer 12

but in that case, you doesn't need to parse value as html: better to use textContent...

also, using Number() allow int or float... there's also a parseFloat() function ;)

Answer 13

parseFloat() allow int as well...

difference between parse{Type} and Number is that formers allow numbers with anything after (ignored), while later only accept numbers:

parseFloat("2px") => 2
Number("2px") => NaN (Not a Number special value)

Answer 14

htmlElementReference was just a meaningful name to say "a variable wich hold the reference of the targeted element ^^

the values assigned were just to show what apply in wich case...

your code must be:

if (x == 1) {
document.getElementById("def").textContent = "welcome";
} else {
document.getElementById("def").textContent = "sorry try again";
}

prefer to use textContent when you not need to put html tags ;P
