输入JavaScript意外结束
[英]Unexpected end of input JavaScript
问题描述
有人可以告诉我这段代码中的JavaScript有什么问题吗？ 它说“输入意外结束”，但是我看不到任何错误。 我所有的语句似乎都在某个时刻结束了，每个语法检查器都说没有检测到错误。

您在多个onclick属性中出现了标点错误，例如：
$("#sls").append('<button onclick = "loadSlide\'1\')" id = "slide_1">Slide 1</button>');
它缺少开头括号。 语法检查不能立即发现问题的原因是因为您将代码放在字符串中。 您不应该这样做。
由于您使用的是jQuery，如何使用.click(function() { ... })而不是内联属性？ 请小心，以确保正确捕获的变量。

第63行的问题
$("#sl").append('button onclick = "newSlide()">New Slide</button>');
应该：
$("#sl").append('<button onclick = "newSlide()">New Slide</button>');
