Try with below code:

JavaScript

// To allow only numbers
$('#inputTxt').keydown(function (e) {
	if (e.shiftKey || e.ctrlKey || e.altKey) {
		e.preventDefault();
	} else {
	var key = e.keyCode;
		if (!((key == 8) || (key == 46) || (key >= 35 && key <= 40) || (key >= 48 && key <= 57)      || (key >= 96 && key <= 105))) {
			e.preventDefault();
		}
	}
});

// To allow value within range between 50 to 100
$("#inputTxt").on("change", function() {
    var val = parseInt(this.value);
    if(val > 100 || val < 50)
    {
        alert('Wrong range');
        this.value ='';        
    }
})

Here inputTxt is ID of text box. You can change as per your need.

Solution 1

Try something like

$('input').keyup( function (event) {
   if (i$(this).val() < x ) || ($(input).val() > y) event.preventDefault(); 
}

you forgot the event.
$('input').keyup( function (event) {
if (i$(this).val() < x ) || ($(input).val() > y) event.preventDefault();
}
