function showAnotherMessage() {
    alert("Hi " + yourName + ".\nThis is an alert message is no longer defined\nin the HTML but in a JavaScript file");
}

你错过了一个＆＃34; +＆＃34;在你的警报中。

Answer 2

转到该功能的window.onload而不是结果，但是该功能的引用并在提醒消息中添加错过的+

alert("Hi " + yourName + ".\nThis is an alert message is no longer defined\nin the HTML but in a JavaScript file");

参考

window.onload = init;

Answer 3

您在警报连接中缺少+。 alert("Hi " + yourName + ".\nThis is an alert message is no longer defined\nin the HTML but in a JavaScript file");

Answer 4

您缺少连接。提示应为小写。

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;

    }

window.onload = init();

Answer 5

如果问题仍然存在，那么它与调用函数

有关

 clickme.onclick = showAnotherMessage;
// instead use below
 clickme.onclick = showAnotherMessage();
