    Look at the letters that appear more than once. They're all very different from each other. This appears to be handwriting. I don't think there is a typeface or font involved.

  • basic javascript question

    how do i make this function display properly?
    The alert do not add the numbers, instead they treat it as strings i guess and alerts "The total value is 5711" when i want it to say "The total value is 23"

    <html>
    <body>

    <script type="text/javascript">

    /* Avoiding errors using typeof operator */

    function addThree(arg1, arg2, arg3)
    {

    if ( (typeof arg1 !="number") || (typeof arg2 !="number") || (typeof arg3 !="number") )
    alert("Please input only numbers!");
    else
    alert("The total value is "+arg1+arg2+arg3);
    }

    var x=5, y=7;
    addThree(x, y , 11);


    </script>

    </body>
    </html>

    If you use + on a number, it converts it to a string I think. + is used to concatenate strings, variables, etc.

    However, adding up nothing but integers works fine. What you are doing, is adding a string, then 3 numbers, which wont work.

    HTML Code:
    <script type="text/javascript">
    
    function addThree(arg1, arg2, arg3)
    {
    	if ( (typeof arg1 !="number") || (typeof arg2 !="number") || (typeof arg3 !="number") )
    	{
    		alert("Please input only numbers!");
    	}
    	else
    	{
    		total = arg1+arg2+arg3;
    		alert("The total value is " + total);
    	}
    }
    
    addThree(1,2,3);
    
    </script>

      I see, so you would have to set the total of the arguments in a variable first and then declare that variable with the string.

      thanx
