HTML
The value attribute of the <button> element is used to set the initial value of a button. You can set this in a <form>. Here, we will be showing an example without using a form.
Following is the syntax −
<button value="value">
Above, value is the initial value.
Let us now see an example to implement value attribute in <button> −
Example
<!DOCTYPE html> <html> <body> <p>Click below to get details about the learning content...</p></br></br> <button id = "button1" value = "Learning" onclick = "demo1()">Get Tutorials</button> <button id = "button2" value = "InterviewAnswers" onclick = "demo2()">Get InterviewQA</button> <p id = "myid"></p> <script> function demo1() { var val1 = document.getElementById("button1").value; document.getElementById("myid").innerHTML = val1; } function demo2() { var val1 = document.getElementById("button2").value; document.getElementById("myid").innerHTML = val1; } </script> </body> </html>
This will produce the following output initially −
The output is as follows when “Get Tutorials” button is clicked −
The output is as follows when “Get InterviewQA” button is clicked −
In the above example, we have created JavaScript functions to get the value in a variable. One of them is demo1()
function demo1() { var val1 = document.getElementById("button1").value; document.getElementById("myid").innerHTML = val1; }
The result of the above gets displayed on the click of a button. The onclick property is set to call the above function demo1() −
<button id = "button1" value = "Learning" onclick = "demo1()"> Get Tutorials </button>
