（3）、浏览本地图片，确定上传按钮

type: ‘POST‘,

cache: false,
contentType: false,
processData: false,
dataType:‘json‘,
beforeSend: function(data){ },
success: function(data){
console.log(data);
if(data==‘fail‘){
layer.msg(‘上传图片失败！‘, 1, 3);
}else{
layer.msg(‘上传图片成功！‘, 2, 1);
showownmarkimgs();/*提取数据库数据，运用dot模板展现所有的自定义水印模板*/
}
},
error: function(data){

}
});
}
