阅读更多关于 JQuery Mobile textarea: how does it use 'rows' attribute?

问题 I would like to dynamically generate textareas, with JQuery Mobile, with varying numbers of rows. I was intending on using knockout for this, data-bind to the rows attribute. E.g. here: http://jsfiddle.net/j7b9A/2/ <label for="textarea-1">5 rows:</label> <textarea rows="5" name="textarea-1" id="textarea-1"></textarea> <label for="textarea-2">10 rows:</label> <textarea rows="10" name="textarea-2" id="textarea-2"></textarea> However, JQuery Mobile seems to ignore the rows attribute, which is

阅读更多关于 Detect the last written word when typing TAB in a textarea or contenteditable div

How to detect and select the last written word when TAB is pressed in a textarea or contenteditable div ? I started to do it with a buffer of the last characters written or key-presses, but then I noticed that there are multiple corner cases: let's say the user writes H E L L U BACKSPACE O the user moves with arrow keys the user can separate words with SPACE (that's what I was using) but also ENTER or a comma, etc. Is there a nice way to detect the last written word? Goal: to code an autocomplete feature, example: thx + <TAB> => Text is replaced by "Thank you very much." You can use current

How to stop html textarea from interpreting html entities into their characters

阅读更多关于 How to stop html textarea from interpreting html entities into their characters

I have an html textarea that is used to display a string from a database. The textarea can be edited and any changes are saved to the database. The problem is that when it recieves entities ® in a string it converts them into their characters, and then when the text is saved the characters overwrite the entities. For example: The database would return the string Microsoft® which would be displayed as Microsoft®, and then saved that way. Is there a way to force textareas to not interpret entities? Follow up: my thought right now is to, on getting the string from the database replace all '&'

问题 with CSS or any other way, is it possible to disallow newlines in a HTML textarea? So basically I want nothing to happen when the user presses "enter". 回答1: Using jQuery, you could do it like this: $(document).ready(function() { $("#t_area").keypress(function(event) { if(event.which == '13') { return false; } }); }); <textarea id="t_area"></textarea> I would also strip out any newlines using PHP or ASP or whatever server-side scripting language you have access to as well to be completely

Using textareas to display live results in iframe, using jQuery, add separate textarea input into iframes head

阅读更多关于 Using textareas to display live results in iframe, using jQuery, add separate textarea input into iframes head

I have created two text areas. one for HTML and one for CSS input. Each have their own IDs. Using a tutorial I've found online, I was able to have these textareas take a users input and display it in an iFrame in real time. Then I was able to write some jQuery, which takes the users input from the textarea with an ID of HTML , and adds it to the iFrames BODY tags, therefor emulating HTML in the iFrame as a live preview. Also, the jQuery uses boolean to detect if there is user input in a textarea without the ID of html (in this case a textarea with an ID of css), it then inserts the input into
