是否可以将 keyup 功能替换为按钮点击功能？

Question

我只是js的初学者。我正在尝试将 keyup 功能更改为按钮功能。谁能帮忙？这是代码，

<textarea id="demo"></textarea>

<script src='https://code.jquery.com/jquery-3.5.1.min.js'>

<script>$("#demo").bind("keyup", function() {

var text = $(this).val();

text = text.replace("good", "sweet")

text = text.replace("night", "dreams")

$(this).val(text); });</script>

您可以简单地添加一个带有 id 或类的按钮并将其绑定到事件，例如：$("#button").bind("click", function() {&nbsp; var text = $("#demo").val();&nbsp; text = text.replace("good", "sweet")&nbsp; text = text.replace("night", "dreams")&nbsp; $("#demo").val(text);});$("#button").bind("click", function() {&nbsp; var text = $("#demo").val();&nbsp; text = text.replace("good", "sweet")&nbsp; text = text.replace("night", "dreams")&nbsp; $("#demo").val(text);});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><textarea id="demo"></textarea><button id="button">click me</button>
