VueJS JSX：如何在渲染 function 上收听“点击”事件？

Question

I'm currently building a SPA app, and here is my problem:

• I want to create a search bar, and when I click on it, a popup with 3 options will be shown

• I have created it with a computed property and by returning 3 buttons, and then call it to render those items:

   methods: { createQuery() { console.log("Click"); } }, data() { return { search_Types: ["Sites", "Pages", "Advance Search"] }; }, computed: { // I will use this value in a render function search_Type_List() { return this.search_Types.map(function(type) { return ( <button class="btn" onClick={this.createQuery({type})}> {type} </button> ); }); } }

• The problem is, inside the computed search_Type_List() scope, I used onClick="createQuery(type)" , with createQuery() as a method.

• I want that every time a button is clicked, it returns the button's text, but it raises an error:

 [Vue warn]: Error in v-on handler: "TypeError: handler.apply is not a function" found in ---> <SearchBar> at src/components/SearchBar.vue <App> at src/App.vue <Root> warn @ vue.runtime.esm.js?2b0e:619 logError @ vue.runtime.esm.js?2b0e:1884 globalHandleError @ vue.runtime.esm.js?2b0e:1879 handleError @ vue.runtime.esm.js?2b0e:1839 invokeWithErrorHandling @ vue.runtime.esm.js?2b0e:1862 invoker @ vue.runtime.esm.js?2b0e:2179 original._wrapper @ vue.runtime.esm.js?2b0e:6917 vue.runtime.esm.js?2b0e:1888 TypeError: handler.apply is not a function at invokeWithErrorHandling (vue.runtime.esm.js?2b0e:1854) at HTMLButtonElement.invoker (vue.runtime.esm.js?2b0e:2179) at HTMLButtonElement.original._wrapper (vue.runtime.esm.js?2b0e:6917)

I just started my VueJS path so there will be many shortcomings, hope everyone can tell me where I went wrong. Any comments will be appreciated. Many thanks everyone !

Answer 1

you missed callback function in onClick prop

onClick={(event) => {
  // do something
}}
