为什么我可以使用以下html调用myFunction()onkeyup:
<div contenteditable="true" onkeyup="myFunction()" >A function is triggered when the user is pressing a key in the input field.</div>
但是我不能用这个来做:
<div contenteditable="true">A function is <span onkeyup="myFunction()" >triggered</span> when the user is pressing a key in the input field.</div>
在第二个中,我试图仅通过特定词
triggered
来调用它,但不确定是否有什么区别。谢谢。查看FIDDLE
最佳答案
尝试这个:
HTML(请注意,您必须在跨度上设置contenteditable,而不是父段落,并且不能两者都设置):
<p>A function is <span class="bold" contenteditable="true" onkeyup="myFunction()" >triggered</span> when the user is pressing a key in the input field.</p>
<p contenteditable="true" onkeyup="myFunction()" >A function is triggered when the user is pressing a key in the input field.</p>
<div id='foo'>Not Yet</div>
CSS:
.bold { font-weight: bold; }
