问题描述
如果我有一个简单的过滤器,请说:
If I have a simple filter, say:
Vue.filter('foo', function (value) { return value.replace(/foo/g, 'bar'); });一个简单的组件:
Vueponent('example', { props: { msg: String, }, });在标记内:
<example inline-template :msg="My foo is full of foo drinks!"> {{ msg }} </example>我可以简单地应用过滤器:
I can simply apply the filter as such:
<example inline-template :msg="My foo is full of foo drinks!"> {{ msg | foo }} </example>我可以在模板中轻松应用过滤器,但我想将该逻辑移回组件。
I can easily apply a filter within the template, however I want to move that logic back into the component.
它不是需要成为过滤器,但基本上是一种为数据字段创建getter和setter的方法。
It doesn't need to be a filter, but basically a way to create a getter and setter for data fields.
类似于:
Vueponent('example', { props: { msg: { type: String, getValue: function(value) { return value.replace(/foo/g, 'bar'); }, } }, });推荐答案
它有点隐藏,我不确定是否它已记录在案,但有关于如何在组件中使用过滤器的 Github问题。
It is slightly hidden and I'm not sure if it is documented, but there is a Github issue on how to use filters in components.
要使用getter和setter,计算属性是完美的:
To use getters and setters, computed properties are perfect:
Vueponent('example', { props: { msg: { type: String, } }, computed: { useMsg: { get: function() { return this.$options.filters.foo(this.msg); }, set: function(val) { // Do something with the val here... this.msg = val; }, }, } });以及相应的加价:
<example inline-template :msg="My foo is full of foo drinks!"> {{ useMsg }} </example>更多推荐
