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）
function bindAvatar1() {
$('#imgSelect').change(function () {
var obj = $(this)[0].files[0];
document.getElementById('ifr').onload=Idndfes;
$('#fs').submit()
})
}
function Idndfes() {
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)
})
})
}
function bindAvatar3() {
$('#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 reader = new FileReader();
reader.onload = function () {
$('#previewImg').attr('src',this.result)
};
reader.readAsDataURL(obj);

通过annotate进行组合分组
