I need to make a webpage run by ajax to display log lines. It would look like a table with rows of log lines. The ajax request could run once every second and ask the server for new log lines since last request. Log lines would first fill a fifo buffer and then one by one line is taken from the buffer and put on the first row, pushing the rest of the rows down. At position 30 (depends on the number of lines possible to display on the screen) the line will fall out of the table, and be deleted.
Is there a smart way to do this in html5, using some animation or somethng? My idea so far would be to use an html table with a special row at the top. The special row is special because i can set the height of this row 10 times per second in order to move the table down. Increasing the height pixel by pixel, and then when the top row is as high as the other rows, i set the height of the top row to 0, and push all data in the table down by one line, and insert a new line into the row below the top row. The top row is always empty. It will look like all rows moves seemless downwards.
Is there a better way to do this in html5 canvas?
