leftOf

production

Filters for an element left of another element.

Takes an optional parameter index to select the nth element (defaults to 0).

Takes an optional parameter intersection_area to specify which elements left of the other element are filtered for based on their vertical position (y-coordinates of bounding box):

• "element_center_line" - considered left of the other element if element's bounding box intersects with a horizontal line passing through the center of the other element
• "element_edge_area" - considered left of the other element if element's bounding box intersects with an area between the top and the bottom edge of the other element
• "display_edge_area" - considered left of the other element no matter where it is placed vertically on the screen (y-axis)

Examples:

---------                   --------- ----------
| text3 |                   | text0 | | button |
---------         --------- --------- ----------
        --------- | text1 |
        | text2 | ---------
        ---------

// General explanation for element_center_line
// This will find text0 and text3
...text().leftOf(..., 'element_center_line').button()

// General explanation for element_edge_area
// This will find text0, text1 and text3
...text().leftOf(..., 'element_edge_area').button()

// General explanation and display_edge_area
// This will find text0, text1, text2 and text3
...text().leftOf(..., 'display_edge_area').button()

// More examples:
// Returns text0 because it is the first element leftOf button
...text().leftOf().button()
...text().leftOf(0).button()
...text().leftOf(0, 'element_edge_area').button()

// Returns text3 because it is the second text touched by the
// horizontal line from the center of button
// Notice: text1 is not touched!
...text().leftOf(1, 'element_center_line').button()

// Returns text3 because it is the third text touched by the
// vertical area leftOf the y-axis of button
// Notice: text2 is not touched!
...text().leftOf(2, 'element_edge_area').button()

// Returns text2 because it is the third element leftOf button
...text().leftOf(2, 'display_edge_area').button()

// Returns no element because button is rightOf the texts
...button().leftOf().text()

• @param {number} [index=0] - Index of element to filter for going into the direction specified. Defaults to 0 which is the first element (zero-indexed) found in that direction.
• @param {INTERSECTION_AREA} [intersection_area="element_edge_area"] - Intersecting with either "element_center_line", "element_edge_area" or "display_edge_area". Defaults to "element_edge_area".
