Abstract

A system and method for magnifying a webpage displayed on a touch screen of an electronic device includes defining a magnification instruction for magnifying content of the webpage on the touch screen, a trigger instruction for each of an automatic mode and a manual mode. The method detects an input instruction according to user input if the electronic device browses webpage. A selected magnification mode is confirmed according to the trigger instruction detected by the electronic device if the electronic device has detected the magnification instruction. The method further confirms a target area to be magnified in the webpage on the touch screen according to the selected magnification mode, and magnifies content of the target area by displaying content of the target area on a full screen of the touch screen.

confirming the selected section to be the target area.

6. The method as claimed in claim 4, wherein if the selected magnification mode is the manual mode, the target area is confirmed by:

recording successive coordinate values comprising X coordinate values and Y coordinate values of the touch screen according to a closed path drawn on the touch screen;

displaying pixels on the touch screen that correspond to the successive coordinate values with the predetermined color;

confirming a rectangular area according to a minimum value of X coordinate values, a maximum value of X coordinate values, a minimum value of Y coordinate values, and a maximum value of Y coordinate values from the recorded successive coordinate values;

confirming the rectangular area to be the target area.

7. A non-transitory storage medium storing a set of instructions, the set of instructions capable of being executed by a processor of an electronic device, cause the electronic device to perform a method of magnifying a webpage displayed on a touch screen of the electronic device, the method comprising:

defining a magnification instruction that allows for magnification of content of the webpage on the touch screen, and trigger instructions for magnification modes of the webpage, the magnification mode comprising an automatic mode and a manual mode;

detecting an input instruction according to user input;

confirming a selected magnification mode according to detection of the trigger instruction by the electronic device, in response to that the electronic device has detected the magnification instruction;

confirming a target area on the webpage to be magnified on the touch screen according to the selected magnification mode and touch operations on the touch screen from the user;

magnifying content of the target area by displaying content of the target area on a full screen of the touch screen.

8. The storage medium as claimed in claim 7, further comprising:

defining a return instruction for returning to display the webpage before the target area is magnified on the touch screen; and

setting the webpage to be divided into “

N*M”

sections for the automatic mode, “

N”

representing a number of horizontal sections of the webpage, and “

M”

representing a number of vertical sections of the webpage.

9. The storage medium as claimed in claim 8, further comprising:

returning to display the webpage before the target area is magnified on the touch screen, in response to that the electronic device has detected the return instruction.

10. The storage medium as claimed in claim 8, wherein the selected magnification mode is confirmed by:

confirming that the selected magnification mode is the automatic mode, upon the condition that the electronic device has detected the trigger instruction for the automatic mode;

confirming that the selected magnification mode is the manual mode, upon the condition that the electronic device has detected the trigger instruction for the manual mode.

11. The storage medium as claimed in claim 10, wherein if the selected magnification mode is the automatic mode, the target area is confirmed by:
