Example: Numbers and Words Sorter

Lets create a script now that accepts any string value and sorts it either alphabetically or numerically:

Enter into the following text box "34 22 23 435 33 2 1 43 54", for example, and press the sort numerically button. Or, try entering "this is a test", and press the sort alpha button.

<script type="text/javascript">

function sortit(a,b){
        return(a-b)
}

function sortvalues(param){
        var inputvalues = document.sorter.sorter2.value.split(" ") // store input as array of words
        if (param == 0){ //if sort alphabetically
                inputvalues.sort()
        }
        else{ //else if sort numerically
                inputvalues.sort(sortit)
        }
        document.sorter.sorter2.value=''
        for (i=0; i<inputvalues.length-1; i++){
                document.sorter.sorter2.value = document.sorter.sorter2.value + inputvalues[i]+" "
        }
        document.sorter.sorter2.value += inputvalues[inputvalues.length-1]
}
</script>

<form name="sorter">
        <textarea rows="10" name="sorter2" cols="50" wrap="virtual"></textarea><br>
        <input type="button" value="Sort alphabetically" onClick="sortvalues(0)">
        <input type="button" value="Sort numerically" onClick="sortvalues(1)">
        <input type="reset" value="Reset">
</form>
