javascript - 不向需要参数的方法传递参数

Question

我试图不向需要参数的方法传递任何参数。到目前为止我有这个，但我似乎无法让它工作:

// HTML 

// this one doesn't pass an argument
<el-button @click:search>Button 1</el-button>

// this one does pass an argument
<el-button @click:search('hey')>Button 2</el-button>

// JS
method: {
    search (searchBy) {
         // if there's a value
         if( searchBy ) {
              console.log(searchBy);
         // if there's no value output this intead
         else
              console.log("nothing to search by");
    }
}

Answer 1

尝试使用 search() 而不是搜索

<el-button @click:search()>Button 1</el-button>

即使你还没有关闭 if 括号
