[Vue warn]: Missing required prop: "value"

[Vue warn]: Missing required prop: "title"

在写vue项目中,在子组件中通过props传值的时候,在父组件中没有定义的话就会看到类似的报错, 这个意思是calendar这个组件中通过props传递一个title属性给父组件,并且title属性是必须的,而在父组件中没有定义这个title,所以要在父组件中定义一下这个title 首先找到calender组件,这样加上title,加完之后,还是出现报错表示,title定义的是字符串类型,而这里的title其实在父组件中还没有被定义,找到data 下的return,添加title:" &quo…

vue报错 Missing required prop: "value"-----（v-model 与 :model的区别）

找不到value值原因:这个错是因为自己绑定值得问题,将v-model 写成了:model . v-model: 是vue内置的双向数据绑定,父子组件的双向绑定,通常用于input数据的双向绑定,用于表单控件以外的标签是不起作用的(即只对表单控件标签的数据双向绑定有效). :model: (v-bind:model)v-bind动态绑定指令,默认情况下标签自带属性的值是固定的,这种只是将父组件的数据传递到了子组件,并没有实现子组件和父组件数据的双向绑定.当然引用类型除外,子组件改变引用类型的数…

vue踩坑记录:[Vue warn]: $attrs is readonly.

今天在用element-ui的DatePicker日期选择器的时候,发现每当点击一次这个组件,控制台就会报警告`[Vue warn]: $attrs is readonly`,但是也不影响实际操作效果.网上搜了一圈后,发现是使用的vue与vue-tempalte-compiler的版本不一致造成的.当时使用的vue是最新版本2.6.10,而vue-template-compiler版本是2.5.21. **解决方法:** 降低vue的版本至2.5.21. `npm uninstall vue`…
