Javascript-缺少变量
Javascript - Variable Missing
本文关键字：变量 Javascript- 更新时间：2023-09-26
我在让这个javascript和css在大约50%的机器上正确工作时遇到了一些问题。奇怪的是，它们都是浏览器最新的工作计算机，我尝试过多种浏览器。我可以验证这个代码是否正常工作，但无法验证为什么它不能在大量机器上工作。这是我使用js:的开始代码

根据我的发现，有三件事可能会发生。
1） 现在的页面将完美地工作。2） 该页面将有一些CSS问题，但javascript仍然可以工作。3） 该页面将完全不起作用。
当页面根本无法运行时，Chrome中的控制台显示错误Error: Uncaught ReferenceError: SList is not definedListPicker._handleMouseUp @ about:blank:510
正如您所看到的，ListPicker不在我的代码中。我完全弄糊涂了。
请帮忙！！：）
在测试了您的代码后，我只能得出结论，您的问题并非源于错误的JavaScript，而是源于编写不当的标记。一些浏览器非常擅长将糟糕的HTML拼凑在一起，但其他浏览器可能不是
我建议您清理并格式化HTML。确保所有标签都正确关闭（在某些情况下，打开），并且不要嵌套太多引号。
此外，您在问题末尾提到的错误只是简单地说明SList变量在定义之前就被引用了。将JavaScript放在<body>标记的底部可能会解决此问题。
