Check whether Enter key is pressed or not and display the result in console with JavaScript?
For this, use onkeypress. Let’s first create input text −
<input id="textBox" type="text" onkeypress="return demoForEnterKey(event)"/>
Now, let’s see the demoForEnterKey() function and check whether enter key is pressed or not −
function demoForEnterKey(eventName) { if (eventName.keyCode == 13) { var t = document.getElementById("textBox"); console.log(t.value); console.log("Enter key is pressed.....") return true; } else { console.log("Enter key is not pressed.....") return false; } }
