最近想做一个关于看图的脚本,正需要这样的功能,在无忧里面发现了。
<script> var img=null; function s() { if(img)img.removeNode(true); img=document.createElement("img"); img.style.position="absolute"; img.style.visibility="hidden"; img.attachEvent("onreadystatechange",orsc); img.attachEvent("onerror",oe); document.body.insertAdjacentElement("beforeend",img); img.src=inp.value; } function oe() { alert("cant load img"); } function orsc() { if(img.readyState!="complete")return false; alert("图片大小:"+img.offsetWidth+"X"+img.offsetHeight); alert("图片尺寸:"+img.fileSize); } </script> <input id=inp type="file"> <br> <button onclick="s()">Test</button>
