v-mode 提示错误 v-model directives require the attribute value which is valid as LHS.

v-mode总是提示错误 v-model  directives require the attribute value which is valid as LHS.

为什么调用过滤总是提示这个错呢？

解决方法

v-model 的值只能是一个变量，是无法应用 filter 的。如果需要应用 filter：

v-model=msgFilteredHTML

export default {
    ...
    computed: { 
        msgFilteredHTML: {
            get() {
                return this.filterHTML(this.msg)
            },
            set(val) {
                this.msg = val
            }
        }
    }
}
