我将数据插入HTML中,如下所示:
<p each="{this.holidayListFirstPart}" if="{hdate}">
<span id="{description}" onclick={showInputBox}>{hdate}:{description}</span>
</p>
我尝试在鼠标点击时将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");
}
问题是当用户在编辑文本后离开textarea时,其抛出错误focusGone
函数未定义:
Uncaught ReferenceError: focusGone is not defined
如何在riotjs中完成这项工作?

您想在运行时更新标记定义,这是不受支持的 https://github.com/riot/riot/issues/1752
但是你可以用另一种方式获得相同的结果
<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>
<强>更新强> 我根据您的评论更新了代码。我们的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 检查这个小提琴https://jsfiddle.net/vitomd/1b2m7xec/6/
