"Error in v-on handler: "TypeError: Cannot read properties of null (reading '0')" 这个错误是因为在v-on的处理函数中,尝试读取一个null对象的属性 '0',而null对象没有 '0' 这个属性。根据引用中的信息,在清除按钮点击时,value2被设置为null,然后在@change绑定的方法中,尝试将null赋值给表单对象中的某个属性,这就导致了上述错误的出现。要解决这个问题,我们可以在方法中添加一个判断,当value2为null时,将其赋值为空字符串,并将时间的查询条件也赋为空。这样就可以避免在赋值操作时出现错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
