如何使用javascript處理NodeJS查詢響應

Question

router.post('/queryrule', function(req, res){
var requestID = req.body;

var frm_requestID = requestID['sbruleid'];
req.checkParams('frm_requestID', 'Not valid Rule ID!').isInt();

var errors = req.validationErrors();
if(errors){
        res.render('queryrule',{
                errors:errors
        });
} else {
  var query = { sbruleid: frm_requestID };
    Ids.searchids(query, function (err, id) {
            if (err) throw err;
            console.log("out: "+ id); //-> the id json query is correct
            res.send(ids); //-> this suppose to send data on my javascript
    });
}}); 

嗨，謝謝您的閱讀和回答。 我的節點js重新發送數據到我的javascript后，我沒有收到任何數據。我有這個nodejs查詢代碼，並且可以正常工作，直到console.log（“ out：” + ids），下面是發布數據的javascript和假設收到了答復，但無法正常工作。

$(document).ready( function() {
$('#btn_frm_search').click( function() {

    query = { 'success' : false, 'data' : "" };

    query = validateFilter();
    if ( !query.success ) {
        return false;
    }

    quertdata = query.data;
//alert("filter:  "+ quertdata['sbruleid']);
    $.post( '/users/queryidsrule' , quertdata , function(data) {
        console.log(data); // -> this suppose to receive data from nodejs but no data receive.
        createResultTable(data);
    });
});

}）;

在這里使用Ajax呼叫

           $.ajax({
                dataType: "json",
                type: 'POST',
                contentType:'application/json',
                url: '/users/queryidsrule',
                data: JSON.stringify(query),
                success: function(response) 
                   console.log(response);
                },
                error: function(xhr, ajaxOptions, thrownError){
                console.log(thrownError);
                }
            });
