Maxvalue validation for textarea using AlloyUI - IE

You might be aware that maxlength attribute of textarea doesn't work for IE8 & IE9. If you still want to restrict the length then you can use below code using alloyUI :

A.one(document).delegate(['keypress','change'],function(e){

var maxLength = this.attr('maxlength');

  if(this.val().length > maxLength) {

   this.val(this.val().substring(0, maxLength));

   e.preventDefault();

}

}, '#<portlet:namespace/>description');

Using jQuery :

jQuery("#<portlet:namespace/>description").on('keypress',function(e){

var maxLength = this.attr('maxlength');

  if(this.val().length > maxLength) {

   this.val(this.val().substring(0, maxLength));

   e.preventDefault();

}

});
