Saya telah memperluas ide bagus dalam jawaban user79865 , untuk membuatnya berfungsi untuk lebih banyak kasus dan dengan beberapa argumen diteruskan ke fungsi kustom.
Untuk menggunakannya, salin kode di bawah ini, dan kemudian dalam panggilan fungsi khusus Anda GetParamRanges()seperti ini, berikan nama fungsi Anda:
function CustomFunc(ref1, ref2) {
var ranges = GetParamRanges("CustomFunc"); // substitute your function name here
// ranges[0] contains the range object for ref1 (or null)
// ranges[1] contains the range object for ref2 (or null)
... do what you want
return what_you_want;
}
Berikut ini contoh untuk mengembalikan warna sel:
/**
* Returns the background color of a cell
*
* @param {cell_ref} The address of the cell
* @return The color of the cell
* @customfunction
*/
function GetColor(ref) {
return GetParamRanges("GetColor")[0].getBackground();
}
Berikut kodenya dan beberapa penjelasan lainnya:
/**
* Returns an array of the range object(s) referenced by the parameters in a call to a custom function from a cell
* The array will have an entry for each parameter. If the parameter was a reference to a cell or range then
* its array element will contain the corresponding range object, otherwise it will be null.
*
* Limitations:
* - A range is returned only if a parameter expression is a single reference.
* For example,=CustomFunc(A1+A2) would not return a range.
* - The parameter expressions in the cell formula may not contain commas or brackets.
* For example, =CustomFunc(A1:A3,ATAN2(4,3),B:E) would not parse correctly.
* - The custom function may not appear more than once in the cell formula.
* - Sheet names may not contain commas, quotes or closing brackets.
* - The cell formula may contain white space around the commas separating the custom function parameters, or after
* the custom function name, but not elsewhere within the custom function invocation.
* - There may be other limitations.
*
* Examples:
* Cell formula: =CUSTOMFUNC($A$1)
* Usage: var ranges = GetParamRanges("CustomFunc");
* Result: ranges[0]: range object for cell A1 in the sheet containing the formula
*
* Cell formula: =CUSTOMFUNC(3, 'Expenses'!B7)
* Usage: var ranges = GetParamRanges("CustomFunc");
* Result: ranges[0]: null
* ranges[1]: range object for cell B7 in sheet Expenses
*
* Cell formula: =sqrt(4+myfunction(A1:C3))
* Usage: var ranges = GetParamRanges("MyFunction");
* Result: ranges[0]: range object for cells A1 through C3 in the sheet containing the formula
*
* Cell formula: =CustomFunc(A1+A2, A1, A2)
* Usage: var ranges = GetParamRanges("CustomFunc");
* Result: ranges[0]: null
* ranges[1]: range object for cell A1 in the sheet containing the formula
* ranges[2]: range object for cell A2 in the sheet containing the formula
*
* @param {funcName} The name of the custom function (string, case-insensitive)
* @return The range(s) referenced by the parameters to the call
