我的点击游戏无法运行
[英]My clicker game won't work
问题描述
I started to work on a clicker game in JavaScript, but it's not working.
我开始用 JavaScript 开发一个点击游戏，但它不起作用。 I used the console to inspect the element to find out why it won't add anything to money and I don't think it is showing the variable either because it won't even show a 0.我使用控制台检查元素以找出为什么它不会向money添加任何东西，我认为它也不会显示变量，因为它甚至不会显示 0。
<!doctype html> <html lang="en"> <head> <script> function addMoney() { var money money+1; var cash = document.getElementById("showmoney"); cash.innerHTML=money; } </script> <meta charset="utf-8"> <title>clicker game</title> </head> <p id="showmoney"></p> <body> <button id="click" onClick="addMoney">click</button> </body> </html>

The call to the function should have parenthesis () :对函数的调用应该有括号() ：
<button id="click" onClick="addMoney()">
Instead of :代替 ：
<button id="click" onClick="addMoney">
Also you have to init you variable money and to define it in the global scope so it will not return to default value zero on every click :此外，您必须初始化变量money并在全局范围内定义它，这样每次单击时它都不会返回默认值零：
var money=0;
Hope this helps.希望这可以帮助。
