我只在IE上遇到这个问题（我正在使用的是IE 9）。它与firefox，chrome，safari一起工作正常。
我需要点击按钮捕获谷歌地图图片。
$(document).ready(function () {
var saveMapToDataUrl = function(){
var transform=$('.gm-style>div:first>div').css('transform');
var comp=transform.split(','); //split up the transform matrix
var mapleft=parseFloat(comp[4]); //get left value
var maptop=parseFloat(comp[5]); //get top value
$('.gm-style>div:first>div').css({ //get the map container. not sure if stable
'transform':'none',
'left':mapleft,
'top':maptop,
})
html2canvas($('#map_canvas'), {
useCORS: true,
logging: true,
allowTaint:false,
onrendered: function(canvas)
{
$('body').append(canvas);
$('#image').html("");
$('#image').html(canvas);
$("#image canvas").attr("id","mcanvas");
var dataUrl= canvas.toDataURL("image/jpeg");
$("#img_val").val(dataUrl);
$("#myForm").submit();
$('.gm-style>div:first>div').css({
left:0,
top:0,
'transform':transform
})
}
});
}
$("#capture").click(function(){saveMapToDataUrl()});
});
在浏览器日志中，我看到以下内容 -

我对这个领域很陌生，如果有人可以提供帮助，那将会非常棒！ 如果需要任何其他代码，请告诉我。 提前谢谢！
