<form name='qform'> <textarea name='q' rows='3' cols='60' wrap='hard' id='q' onkeydown="if (event.keyCode == 13) document.getElementById('clickit').click()"></textarea> <input type='button' value='search' id='clickit' onclick="get();"> </form> I have this form... it doesn't have a submit button because I am using jquery and under this form is a div area where the results will be shown. It is a search engine that does not have an input box but instead has a textarea. This is because it will be a multiple word searcher. The problem is that if I press enter, the query is submitted and everything

TEXTAREAs scroll by themselves (on IE8) every time you type one character

由 安稳与你 提交于 2019-12-02 22:58:35
IE8 has a known bug (per connect.microsoft.com ) where typing or pasting text into a TEXTAREA element will cause the textarea to scroll by itself. This is hugely annoying and shows up in many community sites, including Wikipedia. The repro is this: open the HTML below with IE8 (or use any long page on wikipedia which will exhibit the same problem until they fix it) size the browser full-screen paste a few pages of text into the TEXTAREA move the scrollbar to the middle position now type one character into the textarea Expected: nothing happens Actual: scrolling happens on its own, and the

解决textarea标签上传java后台保存原本样式问题

由 匿名 (未验证) 提交于 2019-12-02 21:53:52
form表单里的textarea标签内容上传到java后台,并把空格换行上传到数据库mysql。 1.前端先不用设置，java后台接收处理。 String pt_work_experience=request.getParameter( "pt_work_experience" ); //25. System. out .print( "25. 01==" +pt_work_experience+ " \n " ); pt_work_experience=pt_work_experience.replace( "/ \n | \r\n /g" , "<br>" ); System. out .print( "25. 02==" +pt_work_experience+ " \n " ); 把这个 pt_work_experience 保存在mysql数据库即可。 2.前端接收java后台传过来的teatarea值（包含换行和空格）： datas [ i ].jingli是java传过来的teatarea值 。 //textarea var work_jingli = datas [ i ].jingli; var reg = new RegExp ( "<br>" , "g" ); work_jingli = work_jingli . replace ( reg , " \r\n

Detecting specific words in a textarea submission

由 半城伤御伤魂 提交于 2019-12-02 20:33:23
问题 I have a new feature on my site, where users can submit any text (I stopped all HTML entries) via a textarea. The main problem I still have though is that they could type "http://somewhere.com" which is something I want to stop. I also want to blacklist specific words. This is what I had before: if (strpos($entry, "http://" or ".com" or ".net" or "www." or ".org" or ".co.uk" or "https://") !== true) { die ('Entries cannot contain links!'); However that didn't work, as it stopped users from

Using nl2br to preserve textarea new lines to mysql… how to return data to textbox nicely?

由 你离开我真会死。 提交于 2019-12-02 20:04:50
问题 I have a form with a textarea whose results are inserted into a mysql database. I'm using nl2br to preserve the line breaks. However, because this inserts br's in the text, when a user goes to edit what they've entered in the textarea, it shows all the br's in the textarea which were saved in mysql (looks ugly for people who don't know html). So, if I don't use nl2br, the line breaks look nice when echoed back in the textarea but not saved in the database correctly. If I use nl2br, the line
