按下按钮更改元素？ [英] Change elements upon button press?

问题描述

我正在开始使用HTML和PHP。做得很好，我理解语法和一切。但是......我知道的仅仅是如何构建可能与我网站中的其他.php文件交互的页面元素。但是如果我想与同一页面中的其他元素进行交互呢？

这就是我想要实现的：
我得到了一些文本和一个按钮。我想按下按钮，这会使我的文本成为一个我可以编辑的文本框，然后再次按下按钮将文本框转换回纯文本。

<这是我不太明白的：与其他元素交互以改变它们的属性/值，似乎只是一些文档，或者我正在寻找错误的地方。如果是这样的话，有人可以指点我正确的学习来源吗？

谢谢。

解决方案

您需要javascript才能达到这个效果....网上和其他地方都有大量的例子： b
$ b

I am getting started with HTML and PHP. Doing alright, I understand the syntax and everything. But... what I know is simply how to build page elements that may interact with other .php files in my site. But what if I want to interact with other elements in the same page?

This is what I'm trying to achieve: I got some text and a button. I want to press the button, and that will cause my text to become a textbox which I can edit, and afterwards press the button again to convert the textbox back to plain text.

That is what I don't quite get: interacting with other elements to change their attributes/values, seems to be little documentation about that, or I am looking in the wrong place. If that is the case, can someone point me to the correct learning source?

Thanks.
