将输入文本更改为textarea就像在Facebook中 [英] changing input text to textarea just like in facebook

问题描述

我想复制您看到一个常规的输入文本，当您单击它更改为textarea。
这是一个隐藏层，还是实际上改变了textarea的输入？如何做呢？

解决方案

我相信它总是一个textarea和焦点，只是改变textarea的高度。 / p>

编辑：是的。他们使用脚本来处理一个textarea，没有输入字段。

 < textarea onfocus ='CSS.addClass c4b900e3aebfdd6a671453，UIComposer_STATE_INPUT_FOCUSED）; CSS.removeClass（c4b900e3aebfdd6a671453_buttons，hidden_​​elem）; window.UIComposer& amp; amp; UIComposer.focusInstance（c4b900e3aebfdd6a671453）;'id =c4b900e3aebfdd6a671453_inputclass =UIComposer_TextArea DOMControl_placeholdername =statustitle =你在想什么？ placeholder =你在想什么？> 
你在想什么？ 
< / textarea> 
  

i would like to replicate that you see a regular input text and when you click it changes into textarea. is this a hidden layer or is it actually changing the input to textarea? how to do it?

解决方案

I do believe it's always a textarea and on focus they just change the height of the textarea.

Edit: yes, it is. They use scripting to do everything with a textarea, there is no input field.

<textarea onfocus='CSS.addClass("c4b900e3aebfdd6a671453", "UIComposer_STATE_INPUT_FOCUSED");CSS.removeClass("c4b900e3aebfdd6a671453_buttons", "hidden_elem");window.UIComposer &amp;&amp; UIComposer.focusInstance("c4b900e3aebfdd6a671453");' id="c4b900e3aebfdd6a671453_input" class="UIComposer_TextArea DOMControl_placeholder" name="status" title="What's on your mind?" placeholder="What's on your mind?">
What's on your mind?
</textarea>
