Error in nextTick: "TypeError: Cannot read properties of undefined (reading 'handleTiny')"

这个错误信息"Error in nextTick: "TypeError: Cannot read properties of undefined (reading 'handleTiny')"通常是由于代码中对一个未定义的属性进行操作引起的。
根据提供的引用信息，错误信息是在使用Vue框架的nextTick函数时出现的。可能是在调用nextTick函数时，Vue实例中的属性handleTiny未被正确定义或者未被正确引用。这可能导致无法读取属性值而出现错误。
解决这个问题的方法可以是：
1. 确保Vue实例中的handleTiny属性已经定义并初始化。可以在Vue实例的data选项中将handleTiny属性设置为默认值。
2. 检查代码中是否正确引用了handleTiny属性。可以使用console.log()来打印相关变量的值，确保它在nextTick函数中被正确引用。
3. 确保在使用nextTick函数之前，handleTiny属性已经被正确赋值，避免出现undefined的情况。
总之，错误信息提示了无法读取未定义属性的问题，需要检查代码中对handleTiny属性的定义和引用是否正确，并确保在使用它之前已经进行了正确的赋值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
