ajax 图片和form上传,用ajaxform上传图片，是上传成功了，但是每次上传重新上传服务器多会比上一次多一张图片！...

代码如下.....迷惘

$(document).ready(function(){

var options = {

success:  showResponse,

dataType: 'json'

};

$("#upload-avatar").on("click",function(){

$('#image').click();

$('#image').on('change', function(){

$('#upload').ajaxForm(options).submit();

});

});

$("#uploadavatar").on("click",function(){

$("#upload-avatar").click();

});

});

function showResponse(response)  {

var filename = response.success;

if(filename == "")

{

$("p_goods_img").html("图片上传失败");

swal("图片上传失败", "", "error");

} else {

$("#p_goods_img").html(filename);

$("#goods_img").val("");

$("#goods_img").val(filename);

swal("图片上传成功", "", "success");

}

}
