Answer 7

Use includes method

if (textarea.value.includes(word))
{
alert("found");
} else {
alert("not found");
}

Answer 8

First target your id

var str = document.getElementbyId('idname').value

Now you can use the search function / method

var sch = str.search(any_word)

If (sch != -1 ) alert( "word found" )
else alert("Not found")

Hope this helps !!

Answer 12

To find a word you can use the syntax "indexOf"
it is -1 when the word is not there in the text

Try to type "namit jain"

Answer 14

Why don't you use regex match and can do this in a very less line of code.

if you want, I can share the code

Add items and start searching below..

Not that you'll do first search and get a message saying "match found" then maybe add more items and when you search / repeat the first search ... Wrong message will be displayed "scope confusion"

But code is correct as found item / items will remain displayed while not found will disappear..

👌..

You use search method but in that example indexOf() had be used..

Answer 17

indexOf is the easiest way, but might not be the fastest way.

Why isn't indexOf working for you? You will get the index of the match, and you know the length of the match, so just highlight the text that matched.

Answer 18

u can use
var textarea = document.queryselector("textarea").textContent;
if textarea.includes(userinput)
alert(msg);
else somthing

explanation:-

1 --> in first line we have created a variable and stored the text from the textarea inside that variable.

2 --> next we have used a JS inbuilt string method ( string.includes(parameter) ) that will find the word we r providing it as a parameter.

3 --> if the value present in the text it will be true else false.
