aurelia-framework 1.1.4

假设：

   <li repeat.for="row of router.navigation" class="files" 
       onclick="alert('${row.title}');" style="cursor:pointer;">
       <a href="${row.href}">${row.title}</a>
    </li>

我希望警报显示当前的row.title，但警报甚至不会触发。

1 个答案:

答案 0 :(得分：2)

使用click.delegate将点击事件处理程序添加到aurelia中的元素。

<template>
 <li click.delegate="onNavClick(row)"  repeat.for="row of router.navigation">
     <a href="${row.href}">${row.title}</a>
  </li>
</template>

在app.ts class

中 
onNavClick(row){
   alert(row.title);
}

这是gist
