  1. In Topic: No answer displays in my disabled textbox?

    Posted 26 Jan 2013

    
<input type='text' id='gradePlaceholder' disabled='disabled' style='width:250px; height:15px;' /> <br />
<input type="button" id="calcAverage" value="Compute Average" onclick='calculateAverage()'/>

    At the risk of really sounding terribly stupid.......how? This is just chapter two so I haven't gotten that far yet.But now it makes sense and for ease of use, the user wouldn't realize they had to click in the box to see the rest of the text.

  3. In Topic: No answer displays in my disabled textbox?

    Posted 26 Jan 2013

    I thought this meant the text box could not be typed in.....

    
<input type='text' id='gradePlaceholder' disabled='disabled'/> <br />


    is that incorrect?
    I took out disabled and tried it and it still says one? How did I disable it? If you cannot tell I am new to Javascript.....extremely new. :)

    Thanks all that really helped me. I also found i misspelled fourth in my code so i corrected that and then switched it up a bit like you all reccomended.
    var d = parseInt(document.getElementById('fourthNumber').value);


    I am not sure about the typo on line #08 .............
    function calculateAverage() //this is the code for the calculation function

    so for now I have not changed that line. I thought the function name was supposed to be one line and using camelcase is ok, right? did I miss something? All feedback is very appreciated because I want to learn, and mistakes, I learn from quickly. I now get the program to return information , but if iIput all 100s in as the grades it returns "my grade is: 1". Why?

    And one last question...... What does the (1) do in this line?
    var avg = (sum / 5).toFixed(1);



    Here is my code again, and of course THANK you all!!!! Your information has helped me understand what I am doing wrong and how to correct it.

    <script type='text/javascript'>
function calculateAverage() //this is the code for the calculation function
{var a = parseInt(document.getElementById('firstNumber').value);
var b = parseInt(document.getElementById('secondNumber').value);
var c = parseInt(document.getElementById('thirdNumber').value);
var d = parseInt(document.getElementById('fourthNumber').value);
var e = parseInt(document.getElementById('fifthNumber').value); //assigns variables to the five grades

var sum = a+b+c+d+e
var avg = (sum / 5).toFixed(1);  
var msg = '';  

if(avg <= 100){ msg = "Excellent! You made an A in the class!"; }  
if (avg <= 89){ msg = "Good Job!  You made a B in the class!"; }  
if (avg <= 79){ msg = "Not Bad!  You made a C in the class!"; }  
if (avg <= 69){ msg = "Do better next time, you made a D."; }  
if (avg <= 64){ msg = "Oh no....you made an F. Sorry you didn't pass."; }  
document.getElementById('gradePlaceholder').value = '  Your average grade is: '+avg;  
alert(msg);  
}</script> 

</head>

<body>

<p>Please enter your five grades and I will display a message with your average. 
<br />
Grade one <input type='text' id='firstNumber' /> <br />
Grade two <input type='text' id='secondNumber' /> <br />
Grade three <input type='text' id='thirdNumber' /> <br />
Grade four <input type='text' id='fourthNumber' /> <br />
Grade five <input type='text' id='fifthNumber' /> <br />  

<input type='text' id='gradePlaceholder' disabled='disabled'/> <br />
<input type="button" id="calcAverage" value="Compute Average" onclick='calculateAverage()'/>

  5. In Topic: incorrectly calculation the return amounts

    Posted 13 Sep 2012

    This is my code for the addition. Is this incorrect? I am not sure why the answer comes out to be .20 instead of .60



    decSolution = (decPrimaryNumerator / decPrimaryDenominator) + (decSecondaryNumerator /  

116             decSecondaryDenominator)
