In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also Fig. 1, the method for the videotex file that the embodiment of the invention provides said method comprising the steps of:
S101: receive the command information of opening text;
S102: in flash, create the index record file corresponding: the byte quantity that sets in advance the content of the text that the individual event index of index record file identified with text; Begin to search from first byte of text, create corresponding individual event index, the start byte of the content that described individual event index record identifies to some extent and the position of end byte in text successively according to the byte quantity that sets in advance;
S103:, read the content of the text of described individual event index sign to the internal memory application according to the start byte and the position of end byte in text of the content that is identified of described individual event index record;
S104: the content that shows the text of described individual event index sign.
Wherein, during the byte of the byte quantity that the content that last individual event index record is identified sets in advance inadequately, then show the byte content of remaining text.
The byte quantity of the content of the text that the individual event index of the index record file that wherein, sets in advance is identified can be 1024 bytes.
Such as, if a text size is 3100 bytes, when then setting up the index record file, the content that first individual event index identified is the content of 1024 bytes of the 1st byte to the of text;
The content that second individual event index identified is the content of the 1025th byte to 2048 byte of text;
The 3rd content that the individual event index is identified is the content of the 2049th byte to 3072 byte of text;
The 4th content that the individual event index is identified is the content of the 3073rd remaining byte to 3100 byte of text.
Wherein, described S103 is according to the start byte and the position of end byte in text of the content that is identified of described individual event index record, and is further comprising the steps of after the step of content of text of described individual event index sign is read in the internal memory application:
Whether the form of judging text is displayable form, if not, convert described text to displayable form.
At present, text comprises three kinds of forms, and first kind is the UNICODE form, and header byte is 0xFF0xFE; Second kind is the UTF8 coded format, and header byte is 0xEE 0xBB 0xBF; The third is the GB2312 coded format.
First kind and second kind is can not display format, but the third is a display format, in an embodiment of the present invention, if text is first kind or second kind of form, then needs first kind or second kind of format conversion are become the third form.
Wherein, further comprising the steps of after the described step S102:
Acquiescence shows the content of the text of first individual event index sign.
Wherein, described S104 shows after the step of content of text of described individual event index sign further comprising the steps of:
Receive the command information of opening text once more;
