直接上代码:
前端【表单与ajax】:
代码语言:javascript复制 <div>
<input type="file" class="form-control" id="filePic" onchange="uploadImg()"/>
</div>
<div>
<img src="" alt="" id="picShow" width="100" height="100" />
</div>
<script>
//图片上传
function uploadImg() {
var formData = new FormData();
formData.append("filePic", $("#filePic").get(0).files[0]);
$.ajax({
url: "/Home/UploadPic",
type: 'POST',
data: formData,
// 告诉jQuery不要去处理发送的数据
processData: false,
// 告诉equerry不要去设置Content-Type请求头
contentType: false,
beforeSend: function () {//发送之前
console.log("正在进行,请稍候");
},
success: function (data) {
if (data != "") {
$("#picShow").attr("src", data);//图片路径
} else {
console.log("上传失败");
}
},
error: function (responseStr) {
console.log("error");
}
});
}
</script>
后台代码(这里是.NET语言测试的):
代码语言:javascript复制 public ActionResult UploadPic(HttpPostedFileBase filePic)
{
if (filePic != null)
{
var path = "/uploads/" filePic.FileName;
filePic.SaveAs(Server.MapPath(path));
return Content(path);
}
else
{
return Content("");
}
}
