Hi Friend,

Try the following code:

1)

<script>
function code(n, digits, padChar) {
    n = n.toString();
    while (n.length < digits) {
        n = padChar + n;
    }
    return n;
}
    var str = window.prompt("Enter String");
    var array = [];
    var totalCount;
    var count=0;

    for(var i = 0; i < str.length; i++){
        if(!array[str[i]]) {
            array[str[i]] = 1;
        } else {
            array[str[i]] += 1;
        }
    }
    sortedArray = [];
    for(var i in array){
        sortedArray.push(code(i.charCodeAt(0), 5, '0'));
    }
    sortedArray.sort();
    for(i = 0; i < sortedArray.length; i++){
        count++;
        }
        document.write("Number of unique letters are: "+count);
</script>

Thanks

Hi Friend,

Try the following code:

4)

<script>
function number(value){
         hunRem = value % 100;
         tenRem = value % 10;
        if (hunRem - tenRem == 10) {
            return "th";
        }
        switch (tenRem) {
        case 1:
            return "st";
        case 2:
            return "nd";
        case 3:
            return "rd";
        default:
            return "th";
        }
    }
    function display(){
    var day=document.form.day.value;
    var mon=document.form.month.value;
    var year=document.form.year.value;

    document.write("Today is "+day+number(day)+" of "+mon+", "+year);
    }
</script>

<form name="form">
<table>
<tr><td>Enter Date of a day:</td><td><input type="text" name="day"></td></tr>
<tr><td>Enter month:</td><td><input type="text" name="month"></td></tr>
<tr><td>Enter year:</td><td><input type="text" name="year"></td></tr>
<tr><td><input type="button" onclick="display();" value="Submit"></td></tr>
</table>
</form>
