The main purpose is to monitor which key is pressed by the keyboard and turn into ASCII code;
Copy Code code as follows:
<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 strict//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd" >
<meta http-equiv= "Content-type" content= "text/html; charset=gb2312 "/>
<title>window.event.keyCode</title>
<body onkeydown= "alert (window.event.keyCode)" >
<input id= "Txtcode" type= "text"/>
</body>
So how to replace the keypad carriage return? First of all, we need to know that the ASCII code of Carriage return is a, the TAB key of the ASCII code is 9 so good to do it;
Copy Code code as follows:
<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 strict//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd" >
<meta http-equiv= "Content-type" content= "text/html; charset=gb2312 "/>
<title> use carriage return instead of the TAB key </title>
<body onkeydown= "if (window.event.keycode==13) {window.event.keycode=9}" >
<input id= "Txtcode" type= "text"/>
<input id= "TxtCode2" type= "text"/>
</body>
In the code above we used the keycode to implement a carriage return instead of the TAB key, simply made a judgment, if the press is a carriage return (13), we will be the tab (9) of the value assigned to it (cheat cheat computer), these small details accumulated, but also a number of not small wealth!
