问题原因:直接在prop上使用v-model会违反prop的单向绑定原则,因为v-model试图在子组件中修改父组件传递过来的数据。这会导致编译错误,提示“local prop bindings are not writable”(本地prop绑定不可写)。 3. 解决不能在prop上使用v-model的方法或建议 为了解决这个问题,可以使用v-bind结合v-on来替代v-model。...
VueCompilerError: v-model cannot be used on a prop, because local prop bindings are not writable. Use a v-bind binding combined with a v-on listener that emits update:x event instead. 报错代码 | <el-dialog | v-model="show" | ^^^ 根据上面的报错信息搜了一下,得到的原因大致如下: 但...

computed: {// 该 prop 变更时计算属性也会自动更新normalizedSize() {returnthis.size.trim().toLowerCase() } } } 另一种在组件内实现v-model的方式是使用一个可写的,同时具有 getter 和 setter 的计算属性。get方法需返回modelValueprop,而set方法需触发相应的事件: <!-- CustomInput.vue --><script>...

当我们使用父组件向子组件传值,当子组件中是v-model使用该值时会报:[Vue warn]: Avoid mutating a prop directly since the value will be overwritten 原因为:在Vue 2.x中移除了组件的props的双向绑定功能,如果需要双向绑定需要自己来实现。 解决办法为:创建针对props属性的watch来同步组件外对props的修改(单向...

v-model只能有一个,(一个组件只有一个model) 个人理解,别的就是语义的区别了,prop.sync表示这个子组件会修改父组件的值,v-model表示这是个表单类型的组件。 v-model一般是表单组件,绑定的是value属性,这个值的双向绑定也不是父组件和子组件的关系,而是view和model的对应关系,因为表单组件的值的变化来自于用户输...
