If ime on, keypress,keydown,keyup can not work well on Webkit based browser.

hi everyone

There will be an important defect on the keypress,keydown,keyup events , if users open their IMEs, because ime will eat  these key events. 

Try this example on Webkit based browser:

If ime off, the example work well.

If ime on, the example can not work.

<input id='castId' size="6" type="text" maxlength="6" onkeyup="checkCastId(this)" style="ime-mode: disabled;" />

<button id="openCastIdBtn" disabled="disabled">Open Cast</button>

<script>

function checkCastId(me){

console.log(me.value);

if(/[6-9]{6}/.test(me.value)){

document.getElementById("openCastIdBtn").disabled = "";

}

else{

document.getElementById("openCastIdBtn").disabled = "disabled";

}

}

</script>
