javascript 不执行而是在地址栏中显示函数名称

我在具有众多功能的各种文件中制作了很多“js 类” - 该项目太大了，无法发布代码。

不知怎的，我直接在终点线制造了一个错误。这意味着在某些浏览器(例如 ff)中，它不会执行所需的函数(它在早期阶段正确执行该函数，而无需更改执行该函数背后的代码，也无需同时更改该函数的代码)。

我使用此方案创建了 js 类和底层函数:

function ClassName(){
   this.FunctionName = function(){
   //something
   }
}

我在地址栏中得到的是: javascript:ClassName.FunctionName()应该发生的是，浏览器只是像 chrome 那样执行该函数，不会出现任何问题。

所以我猜测代码中的某个地方有一个我找不到的坏字符(不属于那里)或者其他地方缺少“”(也许也在另一个类中)-或者类似的东西- 这使得某些浏览器可以正确解释它(例如，Windows 下的 chrome 和 Mac 下的 Safari，但 Windows 下则不行)，而其他浏览器则不能。

但我希望 Stack Overflow 的一位专业人士提供一些线索，告诉我地址​​栏的行为可能是什么，或者如何找到那些丢失的字符或根本不属于的字符到代码。最佳实践是什么，可能有任何工具吗？

chrome和ie开发工具(f12)和firefox firebug没有给我任何控制台错误，所以我现在真的一无所知，也许它在html中？我可以发布 html，因为它不大，因为大部分内容都是由 js 创建的。

                    1. You are using a browser which is not supported or
                    <br>
                    2. You are using Safari on windows (or linux? - not tested till now)

                    <br>
                    In the first case get a supported browser
                    <br>
                    In the second case download Apple Quicktime, close Safari, install Quicktime, run Quicktime till advertisement appears, close Quicktime, run Safari again, browse to this site.

忘了说:页面显示[object Object]

将其更改为onclick，现在我得到:ReferenceError:GameEngine未定义 - 似乎缺少右括号 - 我现在正在搜索，它不在gameEngine中，这意味着它是上面的类之一

最后一个错误是我不小心没有通过“//”注释掉的评论 - onclick 解决了问题

非常感谢您的大力支持!现在，在解决我刚刚发现的性能问题后，我可以准备好要上传的所有内容。再次非常感谢你真的帮了我很多!!

最佳答案

您应该在点击上创建链接，而不是使用 href:

<a onclick="GLOBAL_gameEngine.restartLevel1()">Try Again</a>

此外，如果您想使用 href，您仍然需要将 href 括在引号中

<a href="javascript:GLOBAL_gameEngine.restartLevel1()">Try Again</a>
