不将参数传递给需要参数的方法

Question

我正在尝试不将参数传递给需要参数的方法。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

尝试搜索（）而不是搜索

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

即使您尚未关闭if括号
