In this tutorial we will show you the solution of JavaScript toggle button, here we are going to show you toggle button example. As we know toggle button allows the user to change a setting between two states.
We used conditional statements for toggle a button by changing value attribute with the help of button id.
For access button element by id we needs to use ‘getElementById()’ method.
Step By Step Guide On JavaScript Toggle Button :-
Here we defined input element button type with attributes ‘id, onclick event, value’.
When user clicks on IN-ACTIVE button then onclick event triggers btnToggle() method.
In btnToggle() method for access defined button we collected button id ‘tbtn’ by ‘getElementById()’ method and stored on variable ‘b’.
Using if condition we checking button value attributes value is whether ‘ACTIVE’ or ‘IN-ACTIVE’ then we changing that value to its reverse.
<!DOCTYPE html>
<html>
<head>
<title>TOGGLE BUTTON</title>
</head>
<body>
<input type="button" id="tbtn" onclick="btnToggle();" value="IN-ACTIVE">
<script>
function btnToggle(){
var b=document.getElementById("tbtn");
if(b.value=="ACTIVE"){
b.value="IN-ACTIVE";
}
else if(b.value=="IN-ACTIVE"){
b.value="ACTIVE";
}
}
</script>
</body>

- Both <head> and <title> tags having their pair end tag, so we need to close the ending tags respectively. If you’re not closed anyone of ending tag properly that is also affect the webpage result.
- <body> tag is beginning of main coding part because it contain coding of entire website blocks and elements described here.
- Here we defined input element with attributes ‘type,id,onclick,value’ with respective values ‘button, tbtn, btnToggle(),IN-ACTIVE’.
- In script we defined function btnToggle(), here we collecting button input id ‘tbtn’ by getElementById() method for access input element and stored on variable ‘b’.
- In if condition we checking whether button input element’s value is ‘ACTIVE’ or not. If returns true means then we changing value attributes value to ‘IN-ACTIVE’ using ‘value’ statement.
- In else if condition we checking whether button input element’s value is ‘IN-ACTIVE’ or not. If returns true means then we changing value attributes value to ‘ACTIVE’ using ‘value’ statement.
- Both </body>,</html> tags closed respectively. </body> tag indicates the end of body, Then </html> tag indicates the end of HTML document.
