You can do it like this

$(document).on("keyup", ".caseName_h", function (e) {
    //IE does not pass event
    e = e|| window.event;
    //32 is space key code
    var keyCOde = e.keyCode ? e.keyCode : e.charCode
    if (keyCode == 32) { 
       //DO stuff here
    }
});

You can check your string on spaces by using the indexof command

var str = $(this).val(); if(str.indexof(" ") >=0){alert('spaces');}

This code checks if space is pressed

$(document).ready(function(){
$('#txtChar').keydown(function(e){
if (e.keyCode == 32) { 
alert('space')
}
});
});

There are always ways. Try this

$('.caseName_h').keyup(function(e){
    $(this).val($(this).val.replace(/\s/g,''));
    if(e.keyCode == 32){
        PG_alert('Special characters not allowed!');
    }
});
