» Title: Creative DW Image Show PRO
» Description: Creative DW Image Show PRO is a Dreamweaver extension which enables the user to create multimedia presentations. It combines the features of the popular Creative DW Image Show with the ability to add professional text effects to slides (similar to After Effects). The product is very customizable: the user can choose the duration of the transition effects, the slide motion start and end position, zoom and panning type for both images and texts.
function hexadecimalToDecimal (string) {
array11.splice(0);
array10.splice(0);
string.split ();
for (i = 0; i
Notice that all functions take an integer argument except the function hexadecimalToDecimal which takes a string since a hexadecimal number contains characters. Notice some similarities between the script of this function and the scripts of the functions binaryToDecimal and octalToDecimal. String.substr divides our string into a substring whose first element is of index i and the number of elements in it is 1 (as if we're taking a single character of a specific index in the string). Let's have a trace:
Suppose the user enters: AAB2
for (i = 0; i <4; i ++)
Output:
For i = 0, array10 [0] = 'A'. Since we need a decimal number, we have to convert A to 10, array10 [0] = 10.
For i = 1, array10 [1] = 'A'. Since we need a decimal number, we have to convert A to 10, array10 [1] = 10.
For i = 2, array10 [2] = 'B'. Since we need a decimal number, we have to convert A to 11, array10 [2] = 11.
For i = 3, array10 [3] = 2.
Now, the second for structure calculates the required decimal number since all elements of array10 are numbers.
Notice that I used different arrays in this program. This is important to store values indispensable for function calculation validity and to refrain from errors.
The 'convert' button does the conversion by calling the necessary functions. Notice that I didn't insert a function that, for example, converts from hexadecimal to binary or hexadecimal to octal. This is useless because when I convert from hexadecimal to decimal, I use the function decimalToBinary to further convert the decimal number to binary. That's a very good translation!
