      这是一个流程使用控制，先进行检测如果浏览器支持第一种就执行第一种，以次类推之到最后的方式(这个方式不会出现浏览器不兼容现象)

    Ajax上传方式（需要把头像发送到后端在获取）

    }

        var content =document.getElementById('ifr').contentWindow.document.body.innerText;
         tag='/'+content;
         $('#previewImg').attr('src',tag)

    }
   本地上传预览（在当前就能预览）
    function bindAvatar2() {
        $('#imgSelect').change(function () {
            var obj = $(this)[0].files[0];
                // Ajax发送后台，并获取路径
                // img.src = 获取路径
            var v=window.URL.createObjectURL(obj);
            $('#previewImg').attr('src',v);
            $('#previewImg').load(function () {
                window.URL.revokeObjectURL(v)
            })
