Hello,

How to build a simple js function that, if a text field's max char is 10. Then, after the char on text field is reach 10, automatically pop out alert. Help me please.

boleh try kaji onkeyup event kat form tersebut

Code:

<!-- script -->
<script type="text/javascript">
function NoMore()
{
var x=document.getElementById("myBox");
var textLength = x.value.length;
if(textLength > 10)
{
    alert("Opss, alredy more den 10. wanna troll me? ;D ");
}
}
</script>

<!--form-->
Must !>= 10: <input type="text" id="myBox" onKeyUp="NoMore()" />

camni ka?

aku rasa barcode reader tu pun guna onkeyup.. cuma dia tulis laju, dah tak silap aku dia akan enter sendri kan?

atau ko boleh guna onchange selain onkeyup tu.. so bila content textbox tu berubah je dia akan execute NoMore(), tapi kelemahan dia aku rasa dia akan check kalau x fokus pada textbox tu..

contoh --> http://www.w3schools.com/jsref/tryit.asp...f_onchange
lepas ko tulis, dan ko klik mana2 kat luar kotak tu baru dia execute uppercase() tu..
