Vue报错:Uncaught TypeError: Cannot assign to read only property’exports‘ of object’#Object‘的解决方法
这个错误提示是说在读取一个未定义的属性时出错,具体是在读取一个长度属性时出现的错误。根据引用和引用的内容,可能是因为在某些页面中,客户端验证工作正常,而在另一些页面中出现了这个错误。这可能是由于在页面渲染之前执行了代码,导致无法获取到页面元素,从而引发了错误。解决这个问题的方法是将相关JS代码放到页面代码下面,即放到body内部或者页面的下部,以确保在执行代码时页面元素已经被加载。这样可以避免在读取未定义的属性时出现错误。<span class="em">1</span><span class="em">2</span>
