javascript - How to add onkeydown to body? -


in index.html have code. need add onkeydown event body in main.onload().

any idea how it?

<body id="body"      onload="main.onload();"      onunload="main.unload();"      onmousedown="main.mousedown();" > 
<body id="body"      onload="main.onload();"      onkeydown="tva.keydown(event);"      onunload="main.unload();"      onmousedown="main.mousedown();" >

in javascript block, try use window.onkeydown (mdn).

you can use document.onkeydown , document.body.onkeydown.

here example you:

javascript

document.body.onkeydown = function(e){     alert(string.fromcharcode(e.keycode)+" --> "+e.keycode); };

live demo

the code above can put in valid javascript block (such main.onload() function).
