动态将值绑定到组件的道具

[英]Bind dynamically value to component's props

I have defined custom component with props. 我用道具定义了自定义组件。 when I using this component I need dynamically bind value to on of these props 当我使用此组件时,我需要将值动态绑定到这些道具的一个上

In custom component's template I have defined element like this: 在自定义组件的模板中,我定义了如下元素:

<template>
...
    <div class="input-group-addon" v-show="currency">{{ currency }}</div>
...
</template>

and its prop: 及其道具:

export default {
   ...
    props: {
      currency: {
        type: String
      }
    }
   ...
}

And component's usage in another component: 组件在另一个组件中的用法:

component's template 组件的模板

<custom-component currency="calculateCurrency" ></custom-component>

component's code 组件的代码

export default {
   components: {custom-component},
   data: () => ({
      myProject: null // this is used as v-model in combo box
   }),
   computed: {
      calculateCurrency: function() {
          return myProject.currency; // currency is getter in object myProject
      }
   }
}

so in result I have something like this: 所以结果我有这样的事情: 在此处输入图片说明

I also tried use 我也尝试使用

suffix=calculateCurrency

without quotes but didn't help. 没有引号,但没有帮助。 can you help me fix it please? 你能帮我解决吗? Thanks 谢谢

I believe you are missing a colon on the binding property: 我相信您在绑定属性上缺少冒号:

<custom-component :currency="calculateCurrency" ></custom-component>

Adding that before "currency" will allow for data-binding 在“ currency”之前添加它可以进行数据绑定
