ele is not defined

It seems like you're trying to run some code that uses a variable or function named "ele", but it hasn't been defined yet. You may need to declare or assign a value to this variable or function before using it in your code. Can you provide more context or code so we can better understand the issue?

command "ele" does not exist.
I'm sorry, but I don't understand what you mean by "ele". Could you please provide me with more context or information about what you are trying to do?
Error in v-on handler: "TypeError: _vm.ele.handelChanges is not a function"
引用\[1\]:在JavaScript中,使用let关键字声明的变量不允许在相同作用域内重复声明。因此,如果在同一个作用域内使用let关键字重复声明同一个变量,会导致报错。例如,在函数func()中,let a = 10;已经声明了变量a,再次使用let关键字声明a = 1;就会报错。\[1\]
引用\[2\]:v-model本质上是一个语法糖,它可以简化双向绑定的操作。例如,<input v-model="test">本质上等同于<input :value="test" @input="test = $event.target.value">。v-model会自动将输入框的值与Vue实例中的test属性进行双向绑定,当输入框的值发生变化时,test属性的值也会相应地更新。\[2\]
引用\[3\]:v-show是Vue.js中的一个指令,用于根据条件控制元素的显示和隐藏。例如,<h1 v-show="ok">Hello!</h1>中的ok是一个布尔类型的data属性,当ok为true时,h1元素会显示出来,当ok为false时,h1元素会隐藏起来。\[3\]
根据你提供的错误信息"Error in v-on handler: "TypeError: _vm.ele.handelChanges is not a function",这个错误是由于在v-on指令中调用了一个不存在的函数ele.handelChanges导致的。请检查你的代码,确保ele.handelChanges函数存在并正确命名。如果ele.handelChanges函数不存在或命名错误,可以修正函数名或添加相应的函数来解决这个错误。
