Answer 1

在html5中，您可以在anchor标签中使用download属性，如下所示：

 <a href="http://vignette3.wikia.nocookie.net/disney/images/d/df/Darth_Vader_Render.png/revision/latest?cb=20151222170300" download><img src="http://vignette3.wikia.nocookie.net/disney/images/d/df/Darth_Vader_Render.png/revision/latest?cb=20151222170300" ></a> 

Answer 2

1. click on an image to asing href to the anchor
2. click in the anchor to download image

 <a href="http://vignette3.wikia.nocookie.net/disney/images/d/df/Darth_Vader_Render.png/revision/latest?cb=20151222170300" download><img src="http://vignette3.wikia.nocookie.net/disney/images/d/df/Darth_Vader_Render.png/revision/latest?cb=20151222170300" ></a> 

 var currentImage = ""; $('img').click(function() { var currentImage = $(this).attr('src'); console.log(currentImage); $("#anchor").attr('href', currentImage).attr('download', currentImage); }); 

 img { max-width:50px; } .hidden { display:none; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <img src="http://vignette3.wikia.nocookie.net/disney/images/d/df/Darth_Vader_Render.png" id="vader"> <img src="http://news.toyark.com/wp-content/uploads/sites/4/2015/08/Mafex-C-3PO-and-R2-D2-002.jpg" id="c3po"> <img src="http://vignette4.wikia.nocookie.net/es.starwars/images/6/6f/Anakin_Skywalker_RotS.png" id="annakin"> <a href="" download id="anchor">download image</a>
