textarea賦值是否能綁定事件

元素本身并不支持綁定事件，但是可以通過JavaScript來綁定事件。可以使用addEventListener()方法來為<textarea>元素添加事件監聽器，例如： ```javascript const textarea = document.querySelector('textarea'); textarea.addEventListener('input', function() { console.log('Textarea value changed'); }); ``` 這樣當<textarea>元素的值發生改變時，就會觸發input事件，從而調用事件處理函數。這樣就實現了給<textarea>元素賦值時綁定事件的效果。 </p> </div> <p class="tj-wenzhang recommend-article"></p> <div
