Goe*_*eff 3 html javascript hyperlink
我对编码很新,我正在尝试完成Codecademy的Javascript课程.我已经学习了一些关于HTML/CSS的知识,我几乎完成了JavaScript.我研究过有类似问题的人,但这些解决方案通常涉及JQuery,我还没有学到.
这是我的HTML(index.html):
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="main.js"></script>
</head>
<body>
</body>
</html>
这是我的JavaScript的开头:
alert();
// Acquire character's name and check to make sure it's a string
var charName = prompt("NASA Receptionist: 'Welcome to Mission Control.
May I have your last name, please?'");
var nameCheck = function(charName) {
while (typeof charName === "number") {
charName = prompt("NASA Receptionist: 'Surely, your name is not
a number... Please, may I have your last name?'");
}
};
nameCheck(charName);
注意:index.html与main.js位于同一文件夹中
当我打开index.html时,没有任何反应,甚至没有打开alert().我错过了什么吗？
您的脚本中有错误,因为您无法在不使用转义斜杠的情况下在多行中生成javascript语句.
我收到了这个错误:
SyntaxError:未终止的字符串文字
var charName = prompt("美国宇航局接待员:'欢迎来到任务控制.
这是修改后的代码:
alert();
// Acquire character's name and check to make sure it's a string
//The \r\n\ will format the string in prompt and make it appear in new line
var charName = prompt("NASA Receptionist: 'Welcome to Mission Control. \
\r\n\May I have your last name, please?'");
var nameCheck = function(charName) {
while (typeof charName === "number") {
charName = prompt("NASA Receptionist: 'Surely, your name is not \
\r\n\a number... Please, may I have your last name?'");
}
};
nameCheck(charName);
