//html2canvas.js需要修改1215行代码如下更改
function ImageContainer(src, cors) {
this.src = src;
this.image = new Image();
var self = this;
this.tainted = null;
this.promise = new Promise(function(resolve, reject) {
self.image.onload = resolve;
self.image.onerror = reject;
if (cors) {
//self.image.crossOrigin = "anonymous";//1.去掉此处的anonymous代码改为空
self.image.crossOrigin = "";
}
//self.image.src = src;//2.在源src后面添加一个随机数如时间戳+"?"+new Date().getTime();
self.image.src = src+"?"+new Date().getTime();
if (self.image.complete === true) {
resolve(self.image);
}
});
}
//javascript调用html2canvas时续添加useCORS:true 案例如下：
html2canvas(document.querySelector("#jiequ"), {
canvas: canvas,
onrendered: function(canvas) {
//$("#droppable").hide()
var imgPath = canvas.toDataURL("image/png");
$("#ceshi>img").attr("src",imgPath);
/*$.ajax({
type:"post",
url:configUrl+"/electronicContract/signContract.do",
async:true,
data:{
data:imgPath
},
success:function(data){
alert(data)
}
});*/
//var pHtml = "<img src="+image+"/>";
//$("canvas").html(pHtml);
//document.body.appendChild(canvas)
},useCORS:true
})
