如果问题仍然存在，则与调用函数有关

var yourName;   //global variable accessible to all functions
function showAnotherMessage() {
    alert("Hi " + yourName + ".\nThis is an alert message is no longer defined\nin the HTML but in a JavaScript file");
}

function init() {
    yourName = prompt("Hi. Enter your name.\nWhen the browser window is first loaded\nthe function containing this prompt window is called.", "Your name");
    clickme = document.getElementById("clickme");
    clickme.onclick = showAnotherMessage;
