这是我现在能做的最多的了，剩下的就看你了。哪个函数没有定义？请在调用函数和包含此JS片段的地方发布HTML为什么在警报（“你的浏览器坏了！”）后返回false
；
？您不在函数中，或者是吗？这可能是由于函数中的语法错误造成的。如果可以，请使用Firebug或类似的方法来查看发生了什么。Darin有一个很好的观点。如果浏览器在无效的“return false”上失败，则不会定义wishAdd函数外部。在firefox中运行代码，并查看错误控制台中的“Return在函数外部”看起来不错，但是我如何设置它来处理不同onclick事件的多个函数？@caio我已经准备好将一个项目添加到我的愿望列表中，但是删除它会导致愿望列表完全消失，并且愿望条目不会从数据库中删除。但是Firebug中没有错误。原始帖子会用新代码更新…如果你让我来解决你的问题你的代码将被完全更改，也许你不会理解，好吗？@caio好的。你能举一个例子说明如何处理多个onclick事件吗？@caio如果所有onclick事件都在按钮上，但有些是链接和其他按钮，它们都做不同的事情，那么你的编辑就可以了。继续e所有按钮或所有链接的操作都不起作用。
