    How to take screenshot of a Google map using JavaScript or jQuery? - Stack Overflow

    programmeradmin11浏览0评论

    I want to take a 'screenshot' of a google map in my html file using JavaScript.

    The map is currently loading in div tags, so I am not able to get image using this <div> tag.

    But if I can load it in canvas <canvas> then I can take a screenshot of it very easily, can anybody tell me solution for this problem - that is, how can I load a google map in canvas.

    Or is there any alternative solution for this?

    Reset to default 4

    Why not just use google maps image api?

    You can try using one of those scripts:

    • html2canvas http://html2canvas.hertzen./
    • jsFeedback http://experiments.hertzen./jsfeedback/
