Change Text Dynamically

  To change the text dynamically using JavaScript, you can use the innerHTML property of a DOM element. Here's an example: HTML: php Copy code < p id = "myText" > This is some text. </ p > < button onclick = "changeText()" > Click me </ button > JavaScript: javascript Copy code function changeText ( ) { document . getElementById ( "myText" ). innerHTML = "This text has been changed." ; } In this example, we have a paragraph element with the ID myText and a button that calls the changeText function when clicked. The changeText function uses the document.getElementById method to get a reference to the myText element and then sets its innerHTML property to the new text we want to display.
