bug:

[sanmuw]

app.component('my-component', {
props: {
modelValue: String,
modelModifiers: {
default: () => ({})
}
},
emits: ['update:modelValue'],
methods: {
emitValue(e) {
let value = e.target.value
if (this.modelModifiers.capitalize) {
value = value.charAt(0).toUpperCase() + value.slice(1)
}

  **value = 'sanmu'**
  
  this.$emit('update:modelValue', value)
}

},
template: <input type="text" :value="modelValue" @input="emitValue">
})

为何 value 写了一个定值 <input type="text" :value="modelValue" @input="emitValue"> 只会修改一次
