<p> Below is an example of a client-controlled file upload image size that users can circumvent because of the client-side restrictions. </p>
<script language= "JavaScript" >
<!--
var filemaxsize = 50;//Limit uploaded file size, unit (k)
function Chkform () {
if (document. hwform.photo.value== "") {alert ("Please select Photo");d ocument. HwForm.Photo.focus (); return false;}
if (document. hwform.photofilesize.value<=0) {alert ("Please select a photo");d ocument. HwForm.Photo.focus (); return false;}
if (document. hwform.photofilesize.value>filemaxsize*1024) {alert ("The selected photos exceed" +filemaxsize+ "K, please select Again");d ocument. HwForm.Photo.focus (); return false;}
Alert ("Can be committed, currently testing ..."), return false;
}
