How to add text to a textbox by clicking a button
提问by Samp
I would like to have a button to the right of a textbox which when clicked would populate the textbox with a message. I am assuming I can accomplish this with Javascript but the "onclick" method doesn't seem to work for me. I am probably doing it wrong.
我想在文本框右侧有一个按钮，单击该按钮时会在文本框内填充一条消息。我假设我可以使用 Javascript 完成此操作，但“onclick”方法似乎对我不起作用。我可能做错了。
