将地址转成blob格式(服务器下运行)
<div id="forAppend" class="demo"></div> <script> var eleAppend = document.getElementById("forAppend"); window.URL = window.URL || window.webkitURL; if (typeof history.pushState == "function") { var xhr = new XMLHttpRequest(); xhr.open("get", "test/images/1.gif", true); xhr.responseType = "blob"; xhr.onload = function() {
if (this.status == 200) { var blob = this.response; var img = document.createElement("img"); img.onload = function(e) {
window.URL.revokeObjectURL(img.src); // 清除释放 }; img.src = window.URL.createObjectURL(blob); eleAppend.appendChild(img); } }
xhr.send();
}
else {
eleAppend.innerHTML = '<p style="color:#cd0000;">浏览器不给力,请更换浏览器后重试</p>';
}
</script>
