问题 I have a Chat application. I'd like the cursor in the chatTextArea to get back to the position 0 of the TextArea chatTextArea . This, however, won't work: chatTextArea.setOnKeyPressed(new EventHandler<KeyEvent>() { @Override public void handle(KeyEvent ke) { if (ke.getCode().equals(KeyCode.ENTER)) { ChatClient.main(new String[]{"localhost", String.valueOf(4444), chatTextArea.getText()}); chatTextArea.setText(""); chatTextArea.positionCaret(0); } } }); How can I get it to work? Thank you. 回答1:

问题 I'm trying to make a disabled/uneditable text inside a textarea. I've found a trick to have the first part uneditable here How to lock the first word of a textarea? but my problem is making it at the end of the text. But it may even not be a textarea "html-tag" but it must look like that and editable. I've researched and read a lot, others saying just write it outside and tell them this text will get appended. But yeah. That was my first idea as well. Is there a jQuery plugin or something

问题 This is maybe a stupid problem to solve but i've looked around and i can't manage to find a viable solution.

问题 I have a textarea in a HTML5 website with a proper placeholder="Sample text" attribute. It is displaying nicely until I add RichText support through CKEditor.

问题 I want to place a textarea inside table td . Unfortunately, it stays single-line. <td align="right" valign="top">Текст акции</td> <td> <input type="textarea" rows="10" cols="45" name="push_title" /> </td> If I set its width and height statically, it resizes, but still stays single-line in the middle of it. How can I solve this issue? 回答1: Use the <textarea> element instead. As such: <td align="right" valign="top">Текст акции</td> <td> <textarea name="" id="" cols="45" rows="10"></textarea> <

问题 How can I get a word in textarrea by its current caret position? I tried something like this, however this returns just the words first letter upto the character at caret position. For example: if the cursor is between fo and o it returns fo and not foo as excpected. Fo | o bar is not equal to bar foo. => Fo expects Foo Foo bar is not equ | al to bar foo. => equ expects equal . Here's what I've done so far: function getCaretPosition(ctrl) { var start, end; if (ctrl.setSelectionRange) { start

问题 I have the following code (pulled from this question) for setting a character limit on textareas. function maxLength(el) { if (!("maxLength" in el)) { var max = el.attributes.maxLength.value; el.onkeypress = function () { if (this.value.length >= max) return false; }; } } var maxtext = document.getElementsByClassName("maxtext"); for (var i = 0; i < maxtext.length; i++) { maxLength(maxtext[i]); } And an example of my html for textareas: <textarea maxlength="150" class="maxtext"></textarea>

问题 I would like to have (preferrably in jQuery) regular text input box which can be clicked and dragged by its right-bottom corner (e.g. like textareas have in Chrome) and resized by user ? Can't find any jQuery plugin already implementing this. Can anybody give me hint if something like this exists or how could it be easily implemented ? Thank you in advance. EDIT: I want to be resizable similarly like textarea is in Chrome... 回答1: You don't need jQuery to handle this. What you need is css.
