onkeypress

Some web pages such as GMail and Reddit(with the Reddit Enhancement Suite) have useful keyboard shortcuts that I'd like to use. However, whenever I start typing on one of these pages, the first onkeypress event fires, but then the "Search for text when I start typing" search bar opens and blocks further keys. I don't want to disable "Search for text when I start typing" as I use it on most other web pages. Is there any way to selectively disable it, or to make a keyboard shortcut/bookmarklet to toggle it? Gustavo Rodríguez To disable this in firefox, just go to Tools->Options->Advanced-

I'm working on key handling in Javascript. I have done some research and I'd like to know whether I have a correct understanding of key handling. KeyDown/KeyUp Event The key down and key up events are supported by IE7+ and Firefox 3.5+ I didn't check the earlier versions of the browsers, but I guess that they also support these events. Is it correct to say that each key on the keyboard will always have a keycode. CharCode CharCode value is available on the keypress.Majority of the keys will have the charcodes that represent the actual value. Some keys won't have a charcode associated with them

问题说明 在含有搜索框的网页中，经常需要及时匹配搜索项，因此需要监听input输入框的变化事件。如果使用 onkeydown、onkeypress、onkeyup 这个几个键盘事件来监测的话，除了监听不了右键的复制、剪贴和粘贴这些操作以外，在输入中文的拼音时同样触发，增加请求数不说还浪费流量。 解决方案 本文结合标准的oninput 和 IE 专属事件 onpropertychange 事件来监听输入框值变化。oninput 是 HTML5 的标准事件，对于检测 textarea, input:text, input:password 和 input:search 这几个元素通过用户界面发生的内容变化非常有用，在内容修改后立即被触发，不像 onchange 事件需要失去焦点才触发。 代码实现 $().ready(function(){ //页面加载完毕绑定输入框的oninput事件 var bind_name='input'; if(navigator.userAgent.indexOf("MSIE")!=-1) { bind_name='propertychange'; } $('input').on(bind_name, function() { do something... }); }); 参考链接： http://www.runoob.com/jsref/event

I met some trouble with a javascript. In fact I have in my database many records that are abreviations and ther equivalent, for example, replace tel => telephone etc... So I have this function $('#tags').keyup(function(e){ var code = e.which ? e.which : e.keyCode; console.log(code); if (code == 'tel'){ var input = this.value; input = input.substr(0, input.length -1); console.log(input); input += 'tel'; this.value = input; } }); Actualy this does not work the trouble is that I do not have aby mistakes in the console of javascript. Anykind of help will be much appreciated. Kind regards. SP. ​

I have a keypress handler on a web page assigned to the body element. I really do want it to be active anywhere in the web page. Or so I thought. The keypress events in textual input forms also activate the body handler, which makes sense, but which I don't want. Ideally, I'd like to keep the keypress handler assigned to the body element and somehow exclude just the input forms. Is there any way I can stop the event at the input level and prevent it from propagating to body? (Or is that even the right way to look at HTML DOM events?) It would be easier simply to check which element triggered

I am following this link Find out the 'line' (row) number of the cursor in a textarea . I want to store the line number of all the occurence of "{" in array while user write in textarea. I want to display the array content after it. Here is source code , I have tried: <textarea rows="10" cols="100" id="editor" onkeypress="hello(event);" ></textarea> <div id="lineNo"></div> <script> function hello(e) { var keyp=e.charCode; var c=0,i; var arr=new Array(); if(keyp=='123') { var arr[c++]=getLineNumber(); } for (i=0;i<arr.length;i++) { document.getElementById("lineNo").innerHTML="Array content is..

I have written a piece of javascript code to get the key pressed within a text area. I have used the onkeydown event to capture the key pressed and am calling a function when the event is triggered. Within the function i am using event.which to get the key pressed. But this is not giving the correct key pressed. For any character pressed, it gives the Ascii value of the corresponding upper case character ( 65 to 90 only ). It is not giving Ascii values for the lower case characters, ie 97 to 122, even if a lower case character has been typed. Eg - If i type 'a' it gives the Ascii value of 'A'

I believe this is a very simple question, but I can't find a simple answer to it. I have an infinite loop, e.g. while(1) , for(;;) , and I need to break from the loop on a keypress. What is the easiest way to do this? P.S.: I can't use getch , cin.ignore , or cin.get because it stops the loop. Well, what you want is asynchronous input. All of the methods provided by cin wait for enter. You will have to use system-specific functions for that, or use a library that will do it for you. What you need to do is to not only process your logic in a while loop, but also listen from message pipe from

I'm designing a web based accounting software. I would like to open the "new accounting document" whenever the user press N key for example. And open "settings" whenever he/she is pressing S key. I saw some scripts based on JavaScript and jQuery. But they did not work exactly. Can anyone help me please ? I have tried this script: var code = (e.keyCode ? e.keyCode : e.which); if(code == 13) { //Enter keycode //Do something } $(document).bind('keyup', function(e){ if(e.which==78) { // "n" } if(e.which==83) { // "s" } }); To prevent if an input is focused: $("body").on("focus",":input", function(
