问题 How does the html5 spellcheck attribute work? I am seeing this page with Chrome 17, which is supposed to support spellcheck on <textarea> , (but not on <input type='text'> ), but when I type in some non-words in the textarea given in that page, I see no change. 回答1: The spellcheck attribute is still poorly (if at all) implemented in browsers. For example, when I visit the page you mention in Chrome 18 and type misspelled words into the box “This text area should be checked for mispelled words

问题 For example: A user submits a form with a <textarea name="mytext" cols="35" rows="2"></textarea> and presses ENTER within it. How would I replace the CR-LF with a <br /> ? 回答1: CF has a function for this called ParagraphFormat(): <cfset form.userText = paragraphFormat(form.usertext)/> From the help docs - Replaces characters in a string: Single newline characters (CR/LF sequences) with spaces Double newline characters with HTML paragraph tags ( <p> ) It may do more than you want in that it

问题 I am using JSF2.0 and I have an inputTextArea component and want to prevent the enduser from resizing it.How can I do it.I tried resize="false" but it is not accepting. 回答1: This is to be achieved using the CSS resize property which needs to be set to none . E.g. <h:inputTextarea ... style="resize: none" /> or, better, <h:inputTextarea ... styleClass="unresizable" /> with this in a fullworthy CSS file .unresizable { resize: none; } The same story applies to the PrimeFaces equivalent <p

问题 I am using a few page validation tools one problem i have is they tell me textarea must have rows and cols attribute. If i am setting this in CSS or using display:none (and using it to hold raw text data) can i do something to skip? it seems like the only answer is rows="0" cols="0" each time i use it. But i have a feeling that is not a good solution. 回答1: Stop using a textarea . If you want something to hold raw data, then use a <script> element (if you plan to access it with JS) or an input

问题 I imagined this to be straightforward, but I am unable to find anything that indicates I can use CSS to target non-empty textareas on a page. I'm okay with JS if CSS absolutely does not support this, but even with jQuery I can't find a way to use a selector, but have to explicitly check for a .val(). Some context: I have an optional textarea that expands on focus, but if the user does decide to type something, I don't want it to shrink again when focus leaves. 回答1: Markup-wise, the :empty

问题 Is it possible to detect what text has been selected in a text area using Javascript? I'm looking to show the user controls only when they have selected text 回答1: I've written a cross-browser function for getting the text selected in a textarea or text input and after some toing and froing the final version is I think the best one I've seen. I've posted it on Stack Overflow a few times before. Here's one example: Is there an Internet Explorer approved substitute for selectionStart and

问题 I'm trying to move the caret in a Flex TextArea to the end after appending some text from my code. I've looked through the reference documentation for TextArea and its underlying TextField but it appears there is no method provided to handle this. One approach I've tried is to set focus to the text area and dispatch a KeyUp KeyboardEvent with the event's key code set to the "End" key, but this doesn't work. Any ideas on how to do this? Thanks. 回答1: Try this textArea.selectionBeginIndex =

问题 Chrome makes textareas resizable by default. How can I attach events to the resizing events for the textareas ? Doing the naive $('textarea').resize(function(){...}) does nothing. 回答1: It doesn't look like you can specifically attach events to resizing a textarea.
