You may need to create a custom function when writing a script that requires multiple repetitive tasks that are different from built-in JavaScript functions.
Instructions
Step 1
Enter the value function to initiate the creation of your own custom function and specify the desired name: function function_name.
Step 2
Use the following syntax for the created function: - parentheses () to define variable parameters that are not required for the created user-defined function; - Curly braces {} to display javascript code.
Step 3
Use the following symbols to maintain syntax: - commas - to separate variable parameters; - semicolon - to define the end of the function value. Thus, a user-defined function without parameters looks like this: function function_name () {}; function_name.
Step 4
Use the newly created UDF to change the page display settings or perform calculations and return the result. For this, the return command is used. Example: function sum (a, u) {var c = (a + u); return c;};
Step 5
Take advantage of the ability to create an unnamed user-defined function that can be called by writing to a variable or directly. These functions are commonly referred to as function literals or lambda functions.
Step 6
Expand the "Tools" menu in the upper toolbar of the Open Office application window to perform the operation of creating a custom function with the possibility of subsequent calling in the formulas of a sheet of the document and go to the "Macros" item.
Step 7
Select the Macro Management section and select OpenOffice.org Basic. An alternative way to call the Macro Editor tool is to simultaneously press the Alt + F11 keys.
Step 8
Specify the current document in the Macro group and click the New button.
Step 9
Confirm the execution of the selected operation by pressing the OK button and enter the code of the user-defined function to be created: function function_name () function_name = 1end function.
Step 10
Enter the value "= function_name" (without brackets) in the desired cell in the document sheet.
