Question

我想提醒“运行功能大炮”然后当我按下确定时我只想说“大炮航行到14度”但它会在我的输出中保持打印警报。

JS

function alertMessage (message) {
alert (message);
}
alertMessage("the Battle has begun");



function alertShip (ship, number) {
alert (ship);
document.write (ship + "the ship sails off to " + number + "degrees");

}
alertShip("running function cannons", 14);

HTML

<!DOCTYPE html>
<html>
<html lang="en">
<head>
<meta charset="utf-8">
  <title>Functions</title>

    <!-- This links to the js code specific for this page -->
    <script src="functions.js"></script>
</head>
<body>



  <div id="output"> </div>  
 <div id="output2"> </div>  

</body>
</html>

Answer 1

尝试从document.write中删除ship参数，并将该语句替换为：

document.write（“cannon ship sails off”+ number +“degrees”）;

然后，您应该能够获得所需的输出。

* p.s。：如果您在文本编辑器上执行此操作并尝试在浏览器上运行此操作，则可以考虑将标记更改为：。

我希望这有帮助！

Answer 2

不要给他们相同的变量输出.. alert（ship）然后document.write（ship + .....）。试试这个

function alertShip (ship, number) {
alert (ship);
document.write ("Cannon ship sails off to " + number + "degrees");

为什么我的输出重复？
