[Solved] Check if a text box starts with 92 using javascript [closed]

by


I recommend you read a JavaScript tutorial. Try here.

To answer your question, this will probably work. If you’re wondering why you’re getting downvoted – asking people to write your code for you is generally considered bad form, so try not to do this in future. 🙂

function Validateform(e) {
  if (document.getElementsByName('receiver')[0].value.substring(0, 2) !== "92") {
    e.preventDefault();
    alert("Alert");
  }
}
