v-for的使用，有默认传参的函数额外传自定义参数

男娘i 2022-08-28 05:39 19阅读 0赞

**1.有1个默认参数**

@click = "handle($event, index)"  //用$event 承载默认参数，被触发函数如下，正常接参：
    handle( event, index ){  }

**2.有多个默认参数：**

@click = "((param1,param2)=>{handle(param1,param2,index)})" //利用闭包，被触发函数如下，正常接参：
    handle( event1,event2, index ){   }
