$('#idOfTA').keyup( function(){ var inputString = $('#idOfTA').val(); var shortenedString = inputString.substr(0,(inputString.length -1)); $('#idOfTA').val(shortenedString); }); $('#idOfTA2').keyup( function(){ var max = 5; var len = this.value.length; //alert(len); if(len > max) { var inputString = $('#idOfTA2').val(); var shortenedString = inputString.substr(0,(inputString.length -1)); $('#idOfTA2').val(shortenedString); } });
