selenium ide 选中iframe

• select frame locator
• Selects a frame within the current window. You can select a frame by its 0-based index number (e.g., select the first frame with "index=0", or the third frame with "index=2"). For nested frames you will need to invoke this command multiple times (once for each frame in the tree until you reach your desired frame). You can select the parent frame with "relative=parent". To return to the top of the page use "relative=top".
