由 别来无恙 提交于 2019-11-26 11:17:28
问题 I have a textarea html element on my page that gets reloaded via ajax. The whole textarea is returned each time not just its content, and the content grows over time. Along with the textarea i return the following piece of javascript: <script type=\"text/javascript\" > var textArea = document.getElementById(\'outputTextResultsArea\'); textArea.scrollTop = textArea.scrollHeight; </script> In firefox 3.0.7 this places the scroll bar at the bottom of the textArea, allowing me to see the latest

Can I style the resize grabber of textarea?

由 我与影子孤独终老i 提交于 2019-11-26 09:41:03
问题 My designer just gave me the design with text areas with styled resize grabber. The question is: Can I style it or not ? 回答1: This element is rendered by the browser itself and is not part of the HTML spec. Unless your designer is creating their own browser, you're stuck with the one you get. 回答2: WebKit provides the pseudo-element ::-webkit-resizer for the resize control it automatically adds to the bottom right of textarea elements. It can be hidden by applying display: none or -webkit

What is the best way to emulate an HTML input “maxlength” attribute on an HTML textarea?

由 风流意气都作罢 提交于 2019-11-26 08:25:03
问题 An HTML text input has an attribute called \"maxlength\", implemented by browsers, which if set blocks user input after a certain number of characters. An HTML textarea element, on the other hand, does not have this attribute. My goal is to emulate the behavior of maxlength on an HTML textarea. Requirements: At a minimum, show (CSS change) that the user typed in too many characters. Ideally, block the user from typing more characters, as happens on an HTML input. It is understood that server

line breaks in a textarea

由 时间秒杀一切 提交于 2019-11-26 07:36:57
问题 I know when saving a textarea you can use the nl2br() or str_replace to change the /n to br tags etc. However what im not sure about how to insert line breaks into a textarea. I cant seem to find much about putting the data back into a textarea with those line breaks. For example I have a form where users can update fields. So the user may enter: foo bar baz When that is saved to the database it would be saved as: foo<br />bar<br />baz<br /> Now when that user goes back to that form after a
