Returns a Boolean value indicating the state of the global flag (g) used with a regular expression. Default is false. Read-only.
Remarks
Example
The following example illustrates the use of the global property. If you pass "g" in to the function shown below, all instances of the word "the" are replaced with the word "a". Note that "The" at the beginning of the string is not replaced. This is because the initial letter is uppercase and, therefore, does not match the lowercase "t" in "the".
This function returns a string with a table that shows the condition of the properties associated with the allowable regular expression flags, g, i, and m. The function also returns the string with all replacements made.
