整理几个js上传多张图片的效果

一、普通的上传图片，张数不限制
<!DOCTYPE HTML>
<html>
<head>
    <meta charset="UTF-8">
    <title>上传多张图片</title>
    <style type="text/css">
        .img-div{
            border: 1px solid #ddd;
            border-radius: 100%;
            float: left;
            line-height: 1;
            margin-left: 5px;
            overflow: hidden;
        }

    </style>
</head>
<body>

<script type="text/javascript">
    //选择图片，马上预览
    function xmTanUploadImg(obj) {

        var fl=obj.files.length;
        for(var i=0;i<fl;i++){
            var file=obj.files[i];
            var reader = new FileReader();

            //读取文件过程方法
            reader.onloadstart = function (e) {
                console.log("开始读取....");
            }
            reader.onprogress = function (e) {
                console.log("正在读取中....");
            }
            reader.onabort = function (e) {
                console.log("中断读取....");
            }
            reader.onerror = function (e) {
                console.log("读取异常....");
            }
            reader.onload = function (e) {
                console.log("成功读取....");

                var imgstr='<img style="100px;height:100px;" src="'+e.target.result+'"/>';
                var oimgbox=document.getElementById("imgboxid");
                var ndiv=document.createElement("div");

                ndiv.innerHTML=imgstr;
                ndiv.className="img-div";
                oimgbox.appendChild(ndiv);
               
            }
            reader.readAsDataURL(file);
        }
    }
</script>
<form id="form">
    <input type="file" id="xdaTanFileImg"  multiple="multiple"  name="fileAttach" onchange="xmTanUploadImg(this)"/>
    <div class="img-box" id="imgboxid"></div>
    <div id="xmTanDiv"></div><br/>
    <div id="errordiv" style="margin-top:15px;100%;text-align:center;">
</div>
</form>
</body>
