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 a selected section according to receiving an X coordinate value and a Y coordinate value of a touch point long pressed on the touch screen and the trigger range for each of the sections, confirming the selected section to be the target area, if the selected magnification mode is the automatic mode;

or confirming the target area 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 a 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, and confirming the rectangular area to be the target area, if the selected magnification mode is the manual mode;

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

2. The method as claimed in claim 1, further comprising:

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

3. The method as claimed in claim 2, 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.

4. The method as claimed in claim 2, 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.

5. 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;

dividing the webpage into “

N*M”

sections in the automatic mode, “

N”

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

M”

representing a number of vertical sections of the webpage;

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 by dividing the webpage into the “

N*M”

sections according to a resolution “

A*B”

of the touch screen, “

A”

representing horizontal pixels of the resolution, “

B”

representing vertical pixels of the resolution;

recording a trigger range for each of the sections according to ranges of the horizontal pixels and the vertical pixels on the touch screen of each section;

confirming a selected section according to receiving an X coordinate value and a Y coordinate value of a touch point long pressed on the touch screen and the trigger range for each of the sections;

confirming the selected section to be the target area, if the selected magnification mode is the automatic mode;

or

confirming the target area 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 a 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, and confirming the rectangular area to be the target area, if the selected magnification mode is the manual mode;

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

6. The storage medium as claimed in claim 5, further comprising:

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