mongodb数据库评论数据结构
gid每个商品的ID
status：数据的状态，可以使删除，可以使隐藏
<script>
//查询评论
function getDiscuss(){
$.ajax({
url:'http://192.168.20.222:3000/admin/getDiscuss',
data:{gid:goodsID},
dataType:'json',
type:'post',
success:function(data){
var c=data;
var a='<div class="commentsinfo">';
var b='<p class="theauthor">';
var h='</p><span class="commentsnumber">';
var d='</span><p>';
var e='</p></div>';
var g='<div class="comments">';
var str='';
for (var i = 0; i < c.length; i++) {
var xstr='';
var x=c[i]._contents;
}
}
})
}
</script>
发表评论
<script>
function doDiscuss(){
var con=$('#sendM').val();
$.ajax({
url:'http://192.168.20.222:3000/admin/doDiscuss'
data:{content:con, gid:goodsID},
dataType:'json',
type:'post',
success:function(data){
if(data.result =='yes'){
$('#sendM').val('');
getDiscuss();
alter('发表成功')
}else if(data.result=='noLogin'){
$('#hiddenLogin').click();
}
}
})
}
</script>
//获取所有评论
javascript序列化：serialize是一个json对象
//获取评论
export.getDiscuss=function(req,res,next){
goodsModel.getDiscuss(req.body.gid,'discuss',function(result){
if(result !='error'){
res.json(result);
}else{
res.json('error');
}
})
}
