textarea

问题 I have two files. First file is a form and the second file displays result. First file: <form action="show.php" method=post> <textarea name="test" cols=40 rows=6> </textarea> <input type=submit value="submit"> </form> Second file: <?php $text = trim($_POST['test']); $textAr = explode("\n", $text); for ($i=0; $i<sizeof($textAr); $i++) { $link = str_replace(" ", "", $textAr[$i]); echo $link."---<br>"; } ?> When I enter in the form for example one two three the result is: one --- two --- three--

问题 We display a piece of signed XML in a TEXTAREA. The signing takes into account the whitespace, so it is critical that this is maintained. The user then copies and pastes this into an application that validates the XML... we've not had a problem with this until now... IE9 is rending the text slightly differently. When I copy it into a HEX editor, I can see that IE9 is rendering newlines as 0xA... put it into compatibility mode (or use IE6,7,8, Chrome, Firefox etc.) and it gets rendered as 0xD

问题 I need to have a control which will wordwrap, add scrollbars, etc - but ignore the enter key and jump to the next control using tab/shift tab. I can't seem to get this right. This is the control I have done, and it seems to just simply stay in the text area. (This was used from an old example online and it seems to work only if the textArea is in the same node as the rest). public class TabAndEnterIgnoringTextArea extends TextArea { final TextArea myTextArea = this; public

问题 I'd like an input field that I can have javascript set certain attributes for, for different parts of the input field. A simple example to demonstrate what I'd like to do: let's say I want to underline all curse words in an input text area. So the javascript would check the input text area when a new letter is inserted, and for any words matching my array of recognized curse words, it would underline the word. Note, I do not want the user/client to be able to set any attributes of the text, I

问题 Is there any way to make textarea display lines in colors? What I am trying to achieve is every second line colored, i.e. white,grey,white,grey,white,grey... for better readability. Users are supposed to write in lots of stuff, as in "enter names, each one from new line". I do use jQuery anyway so if they made some simpler solution for this it would be perfect. 回答1: What you are looking for is called Zebra striping, maybe that will help with some google searching. However, I don't think there

问题 I expect part of my frame contains the JTextArea but it occupies entirely. I cannot trace the error here. import java.awt.*; import javax.swing.*; public class EchoServer { public static void main(String args[]) { CalcFrame c = new CalcFrame(); CalcTextArea a = new CalcTextArea(); } } class CalcTextArea { JTextArea historyDisplayer = new JTextArea("",50,20); CalcTextArea() { //historyDisplayer.setVisible(true); historyDisplayer.insert("Hello World", 0); Color bg = new Color(23,34,56);

问题 I'm trying to make a date textbox on my blog, and the date is only numbers. I don't want anybody making a mistake typing a letter. Is there any way to limit the characters to only numerals? Thanks! 回答1: If you use jQuery, you can do it like in this jsfiddle $('input').keypress(function(e) { var a = []; var k = e.which; for (i = 48; i < 58; i++) a.push(i); if (!(a.indexOf(k)>=0)) e.preventDefault(); }); 回答2: Use HTML5 input number type instead and leverage native browser validation. Thus, no
