我将数据插入HTML,如下所示:
<p each="{this.holidayListFirstPart}" if="{hdate}">
<span id="{description}" onclick={showInputBox}>{hdate}:{description}</span>
</p>
我正在尝试在mouseclick上将
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文本区域时,未定义
focusGone
函数的抛出错误:Uncaught ReferenceError: focusGone is not defined
如何在riotjs中进行这项工作?
最佳答案
您想在运行时更新标签定义,但不支持
https://github.com/riot/riot/issues/1752
但是您可以通过其他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>
更新资料
我根据您的评论更新了代码。这个想法是要知道如何访问所需的数据,您可以使用event.currentTarget或直接使用this.object_id
