Count textarea characters

由 坚强是说给别人听的谎言 提交于 2019-11-27 01:00:35
I am developing a character count for my textarea on this website . Right now, it says NaN because it seems to not find the length of how many characters are in the field, which at the beginning is 0, so the number should be 500. In the console in chrome developer tools, no error occur. All of my code is on the site, I even tried to use jQuery an regular JavaScript for the character count for the textarea field, but nothing seems to work. Please tell me what I am doing wrong in both the jQuery and the JavaScript code I have in my contact.js file. $(document).ready(function() { var tel1 =

This question already has an answer here: How can I block further input in textarea using maxlength 5 answers How can I set the maxlength in a textarea ? And why maxlength is not working properly in textarea ? Before HTML5, we have an easy but workable way: Firstly set an maxlength attribute in the textarea element: <textarea maxlength='250' name=''></textarea> Then use JavaScript to limit user input: $(function() { $("textarea[maxlength]").bind('input propertychange', function() { var maxLength = $(this).attr('maxlength'); if ($(this).val().length > maxLength) { $(this).val($(this).val()

Implementing a resizable textarea?

由 江枫思渺然 提交于 2019-11-27 00:02:27
问题 How does Stackoverflow implement the resizable textarea? Is that something they rolled themselves or is it a publicly available component that I can easily attach to textareas on my sites? I found this question and it doesn't quite do what I want. autosizing-textarea That talks more about automatically resizing textareas whereas I want the little grab-area that you can drag up and down. 回答1: StackOverflow uses a jQuery plugin to accomplish this: TextAreaResizer. It's easy enough to verify

Firefox cache textarea value?

问题 I found a strange issue. Open a simple page in Firefox, the code is simple as below: <html> <body> <textarea></textarea> </body> </html> In Firefox, I type some characters in the textarea. Then I click refresh button of the browser. Surprisingly, after the page refreshed, what I typed is still there in textarea. However, if I just focus on URL bar and press ENTER key, the textarea is clear after refreshing. I reproduced this in Firefox 3.6.12 in Linux and 3.6.3 in MacOS. And, I have only

Inserting text at cursor in a textarea, with Javascript

由 萝らか妹 提交于 2019-11-26 22:59:08
I've had a look round the web for solutions, and there are some, but they all seem to split code into supporting IE and Firefox. I was wondering if there's a more elegant way which would work on every browser, to insert some text at the cursor in a textarea. Thanks very much, Rich No, there isn't. IE has its TextRange objects to do the job. IE >= 9 and everything else for the last long time has selectionStart and selectionEnd properties on textareas and text inputs. This particular task isn't too bad: the following will delete the current selection (if one exists), insert text at the caret and

Is there a way to make a text area partially editable? (make only portions of the text editable)

由 余生颓废 提交于 2019-11-26 22:39:27
I just came across a situation in which it would be an elegant solution to have only portions of a text area (previously loaded with text) be editable while other portions are not ("greyed out", so to speak). Is this possible at all by using javascript in general? I would be using jQuery. You could do this (just an outlined idea, no code): Devise a regex that matches your entire text. Use fixed strings for the unmodifiable parts, and use [\s\S]*? for the modifiable parts. Use ^ and $ to anchor your regex. /^This is fixed text\. Now something editable:[\s\S]*?Now fixed again\.$/ Now react to
