變量javascript

所以我有一個彈出窗口或提示，當你輸入你的名字或任何它說「你好'名字'！你今天好嗎？」我想將它與我要去的泡泡字母結合起來。所以輸入會改變泡泡字母。 http://codepen.io/anon/pen/PZjoaR 變量javascript

爲什麼不提示'myName'？ 'var myName = prompt（「請輸入你的名字」，「哈利波特」）;' – AshBringer

你只需要調用一個名字提示函數內部drawName功能。

function myFunction() { 
    var person = prompt("Please enter your name", "Harry Potter"); 
    if (person != null) { 
    document.getElementById("demo").innerHTML = 
    "Hello " + person + "! How are you today?"; 


    drawName(person, letterColors); 


    } 
}
