StrLastIndex ( STRING, SUBSTRING )
Gets the character index of the last occurrence of a string in another string.
Parameters
| Parameter | Type | Description |
|---|---|---|
| STRING | VALUE(STRING) | The string to search in. |
| SUBSTRING | VALUE(STRING) | The substring to search for. |
Returns
| VALUE(INTEGER) | The index of the last occurrence of the string (0 or greater), or -1 if not found. |
What It Does
This function returns the index of the last occurrence of the second string in the first string (search starts from end of string). If the second string cannot be found in the first, -1 is returned. Both provided values are interpreted as strings before the search. The search is case-sensitive.
a = strLastIndex("applesauce", "sauce"); // a = 5
a = strLastIndex("banana", "na"); // a = 4
a = strLastIndex("tomato", "to"); // a = 4
a = strLastIndex("oranges", "stuff"); // a = -1
a = strLastIndex(12345, 23); // a = 1
a = strLastIndex(225.75, "5"); // a = 5
a = strLastIndex("ABCDEFG", "a"); // a = -1

// Index Search
textln(strIndex("Apples and Oranges", "Apples")); // 0
textln(strIndex("Apples and Oranges", "Pears")); // -1
textln("");
// Index vs. LastIndex
textln(strIndex("Apples and Oranges", "an")); // 7
textln(strLastIndex("Apples and Oranges", "an")); // 13
textln(strIndex("Apples and Oranges", "es")); // 4
textln(strLastIndex("Apples and Oranges", "es")); // 16
textln("");
// Contains
textln(strContains("Apples and Oranges", "Apples")); // true
textln(strContains("Apples and Oranges", "apples")); // false
textln(strContains("Apples and Oranges", "Pears")); // false
textln(strContains(1234, 23)); // true (numbers are converted to strings)
textln(strContains(0.56, ".")); // true (numbers are converted to strings)
textln("");
// Starts With
textln(strStartsWith("Apples and Oranges", "Apples")); // true
textln(strStartsWith("Apples and Oranges", "apples")); // false (case sensitive)
