javascript - Uncaught ReferenceError : function is not defined error when calling riot function

Question

我将数据插入到 HTML 中，如下所示:

<p each="{this.holidayListFirstPart}" if="{hdate}">
    <span id="{description}" onclick={showInputBox}>{hdate}:{description}</span>
</p>

我试图在鼠标单击时将 span 标记转换为 textarea ，以便用户可以像这样编辑文本:

showInputBox(e) {
    self.textContent = document.getElementById(e.target.id).innerHTML;

    var mySpan = document.getElementById(e.target.id);
    var customTextArea = document.createElement("textarea");
    customTextArea.id = e.target.id;
    customTextArea.setAttribute('onmouseout','{focusGone}');
    customTextArea.innerHTML = self.textContent;
    mySpan.parentNode.replaceChild(customTextArea, mySpan); 
}

focusGone(e){
    console.log("lost focus");
}

问题是当用户编辑文本后离开文本区域时，会抛出 focusGone 函数未定义的错误:

Uncaught ReferenceError: focusGone is not defined

如何在 riotjs 中实现此功能？

Answer 1

您试图在运行时更新标签定义，但不受支持 https://github.com/riot/riot/issues/1752

但是你可以用另一种方式得到相同的结果

<my-tag>
<my-tag>
  <p each="{this.holidayListFirstPart}" if="{hdate}">
        <span show="{!parent.editing}" id="{description}" onclick={showInputBox}>{hdate}:{description}</span>
        <textarea id="editText" onmouseout="{parent.focusGone}" show="{parent.editing}"></textarea>
  </p>

  this.holidayListFirstPart = [{description:'des1', hdate:'123'}, {description:'des2'}]
  this.editing = false

  showInputBox(e) {
      this.editing = !this.editing 
      this.editText.innerText = e.currentTarget.innerText
  }

  focusGone(e){
    this.editText.innerHTML = e.currentTarget.value
    alert('result: ' + this.editText.innerHTML);
  }
</my-tag>

更新 我根据您的评论更新了代码。想法是知道如何访问您需要的数据，您可以使用 event.currentTarget 或直接使用 this.object_id 检查这个 fiddle https://jsfiddle.net/vitomd/1b2m7xec/6/
