Filters the array keys and leaves elements with keys that are presented in all arrays. Changes the arrays passed as a parameters.
filter_eqkeys(p1, p2, ... pn);
|p1, p2, ... pn||Array variables that you need to filter.|
Returned value: no.
After using this function, the arrays will always have the same number of elements, regardless of what they were prior to use. Therefore if after get-function arrays have different number of elements (which means that after saving correspondance will be failed, in this case store will warn you) after use filter_eqkeys some elements will be filtered, which is not always correct. Generally, if after get-function arrays have not the same number of elements, it means that you need to change xpath from a single get-function, or use a design group.
If the built-in browser uses data filtering and number of rules in group is more than one, the script is always added filter_eqkeys with variables corresponding to the names of the rules of the group.
Example 1. Same keys of variables a2, b2, c1 will be only 1 and 3.
