getting boolean value from text input based on id

Question

I'm trying get the value from text box using ID but I'm getting boolean value

<input type="text" tabindex="4" class="form-control input-sm" required onkeypress="return onlycode(event,this);" maxlength="40" id="MaterialCode" name="MaterialCode" placeholder="Material Code" autocomplete="off">

var matcode = $("#MaterialCode").val();

How to get the actual value and what's wrong my html code?

You can use the !! shortcut to convert a value to a boolean: var matcode = !!$("#MaterialCode").val();. If that doesn't work for you then please provide more detail in the question — Rory McCrossan

You can get Boolean Value from a variable by Using !!

Example :

const falsyValue=0
console.log(!!falsyValue) //Log False
const truthyValue=1
console.log(!!truthyValue) //Log True

In your case, you need just to use !! to convert your value into boolean

var marcode = !!$("#MaterialCode").val();

Thank you and I hope this answer can help
