在我的应用程序中,我html2canvas用于将HTML转换为画布,之后我将使用toDataURL()chrome中的所有内容将该画布转换为图像,图像在页面加载后立即下载,但在safari中将图像加载到同一页面没有下载.

$(document).ready(function(e) { 
    html2canvas(document.body, {
        onrendered: function(canvas) {
        var test = document.getElementsByClassName('test');      //finding the div.test in the page
        $(test).append(canvas);                               //appending the canvas to the div
        var canvas = document.getElementsByTagName('canvas');       
        $(canvas).attr('id','test');                              //assigning an id to the canvas
        var can2 = document.getElementById("test");
        var dataURL = can2.toDataURL("image/png");
        document.getElementById("image_test").src = dataURL;     //assigning the url to the image
        $(canvas).remove();                                   //removing the canvas from the page
        download(can2,'untitled.png');
        function download(canvas_name,filename)
        {
            var tempLink = document.createElement('a');
            e; 
            tempLink.download = filename;
            tempLink.href = dataURL;
            if …
