SyntaxError: missing ; before statement

Here's my script
function getJSONData() {
var value = [];
var couchDB ="http://X.X.X.X:5984/databasename/_design/name/_view/All%20Content?jsoncallback=?";
$.getJSON( couchDB , function( data ) {
format: "jsonp"
console.log(data);
$.each(data.rows, function(index, row){
value.push(row.value);
});
});
}
How can I get well formed json back from this get request ?
This is happening because your server is returning json data and client is trying to read JSONP fromatted data. you should enable jsonp on couchdb by changing variable allow_jsonp to true under configuration tab.

I am working in NodeJS with CouchDB 2.1.1.
I'm using the http.request() method to set various config settings using the CouchDB API.
Here's their API reference, yes, I've read it:
Configuration API
Here's an example of a working request to set the logging level:
const http = require('http');
var configOptions = {
host: 'localhost',
path: '/_node/couchdb#localhost/_config/',
port:5984,
header: {
'Content-Type': 'application/json'
}
};
function setLogLevel(){
configOptions.path = configOptions.path+'log/level';
configOptions.method = 'PUT';
var responseString = '';
var req = http.request(configOptions, function(res){
res.on("data", function (data) {
responseString += data;
});
res.on("end", function () {
console.log("oldLogLevel: " + responseString);
});
});
var data = '\"critical\"';
req.write(data);
req.end();
}
setLogLevel();
I had to escape all the quotes and such, which was expected.
Now I'm trying to get CouchDb to accept a setting for compaction.
The problem is that I'm attempting to replicate this same request to a different setting but that setting doesn't have a simple structure, though it appears to be "just a String" as well.
The CouchDB API is yelling at me about invalid JSON formats and I've tried a boatload of escape sequences and attempts to parse the JSON in various ways to get it to behave the way I think it should.
I can use Chrome's Advanced Rest Client to send this payload, and it is successful:
Request Method: PUT
Request URL: http://localhost:5984/_node/couchdb#localhost/_config/compactions/_default
Request Body: "[{db_fragmentation, \"70%\"}, {view_fragmentation, \"60%\"}, {from, \"23:00\"}, {to, \"04:00\"}]"
This returns a "200 OK"
When I execute the following function in my node app, I get a response of:
{"error":"bad_request","reason":"invalid UTF-8 JSON"}
function setCompaction(){
configOptions.path = configOptions.path+'compactions/_default';
configOptions.method = 'PUT';
var responseString = '';
var req = http.request(configOptions, function(res){
res.on("data", function (data) {
responseString += data;
});
res.on("end", function () {
console.log("oldCompaction: " + responseString);
});
});
var data = "\"[{db_fragmentation, \"70%\"}, {view_fragmentation, \"60%\"}, {from, \"23:00\"}, {to, \"04:00\"}]\"";
req.write(data);
req.end();
}
Can someone point at what I'm missing here?
Thanks in advance.
You need to use node's JSON module to prepare the data for transport:
var data = '[{db_fragmentation, "70%"}, {view_fragmentation, "60%"}, {from, "23:00"}, {to, "04:00"}]';
// Show the formatted data for the requests' payload.
JSON.stringify(data);
> '"[{db_fragmentation, \\"70%\\"}, {view_fragmentation, \\"60%\\"}, {from, \\"23:
00\\"}, {to, \\"04:00\\"}]"'
// Format data for the payload.
req.write(JSON.stringify(data));
I want to call JSON data as much as the amount of data in the store. Here is the code:
storeASF.each(function(stores) {
var trano = stores.data['arf_no'];
Ext.Ajax.request({
results: 0,
url: '/default/home/getdataforeditasf/data2/'+trano+'/id/'+id,
method:'POST',
success: function(result, request){
var returnData = Ext.util.JSON.decode(result.responseText);
arraydata.push(returnData);
Ext.getCmp('save-list').enable();
Ext.getCmp('cancel-list').enable();
},
failure:function( action){
if(action.failureType == 'server'){
obj = Ext.util.JSON.decode(action.response.responseText);
Ext.Msg.alert('Error!', obj.errors.reason);
}else{
Ext.Msg.alert('Warning!', 'Server is unreachable : ' + action.response.responseText);
}
}
});
id++;
});
storeARF.loadData(arraydata);
StoreASF contains data[arf_no] which will be used as a parameter in Ajax request url. StoreASF could contain more than one set of the object store, so looping is possible. For every called JSON data from request would be put to array data, and after the looping is complete, I save it to storeARF with the loadData method.
The problem is, my data format is wrong since loadData can only read JSON type data. I already try JSON stringify and parse, but couldn't replicate the data format. Any suggestion how to do this? Thank you.
Rather than using Ext.util.Json.decode(), normalize the data in success() method using your own logic. For example:
success: function (response) {
console.log(response);
var myData = [];
Ext.Array.forEach(response.data, function (item) {
myData.push({
name: item.name,
email: item.email,
phone: item.phone
});
});
store.load();
}
I am pretty new to JSON / Jquery world so please bear with my ignorance.
I am trying to read an output from a Json data returned by webservice call like below :
My webservice call is here:
http://example.com/getPortfolioListByContact.json?component=C1&contactId=510297
This return the data as :
{
"data": [
{
"PORTFOLIO_ID": 13495,
"SUBSCRIPTION_ID": 1653,
"STATUS": "ACTIVE",
}
],
"success": true
}
Now I am trying to get alert onthe Json Data returned as string and also want to get this as Parsed /
<script>
var parsed ;
$.getJSON("http://example.com/getPortfolioListByContact.json?component=C1&contactId=510297", function(data){
alert(data.SUBSCRIPTION_ID);
});
parsed = JSON.parse(data);
alert(parsed) ;
</script>
I am getting the response in Alert as "Undefined" . I may not be doing right handling the success handler . I want to get each value and specific value of the json data returned.
Please help.
Thanks
I am getting the response in Alert as "Undefined".
Reason : You are trying to parse the API response out of the scope. As data object is only accessible in the promise returned by the API call.
Try this hope it will work as per your expectation :
$.getJSON("http://example.com/getPortfolioListByContact.json?component=C1&contactId=510297", function(res) {
var data = res.data;
alert(JSON.stringify(data));
});
You are calling data out side the scope.
<script>
var parsed ;
var myData;
$.getJSON("http://example.com/getPortfolioListByContact.json?component=C1&contactId=510297", function(data){
myData = data;
alert(data.SUBSCRIPTION_ID);
});
parsed = JSON.parse(myData);
alert(parsed) ;
</script>
Well, i'm having some difficult to understand the use of angular.toJson. I completely understand that it changes to a json object...
But, how can i send this obj to the server ?
The server already gives a json obj when 'GET', but how use it to 'POST' and others?
sorry, i'm new :)
You can create factory in your app:
var app = angular.module('myApp', []);
app.factory('requestsFactory', ['$http', function ($http) {
return {
postData: function (data) {
var url = // some url to send your data
return $http.post(data, url);
};
};
}];
And now, you can post your data from controllers:
app.controller('yourController', ['$scope', 'requestsFactory', function ($scope, requestsFactory) {
...
requestFactory.postData(anyData).success(function (result) {
// if server send any response
}
...
}]);
Also you can use $http for GET, PUT, DELETE requests. Click here for more information
You don't actually need to call angular.toJson() yourself when posting data to a server or retrieving data from the server using the $http service.
This is the default behaviour that Angular does for you.
From the docs:
Angular provides the following default transformations:
Request transformations ($httpProvider.defaults.transformRequest and
$http.defaults.transformRequest):
If the data property of the request configuration object contains an
object, serialize it into JSON format.
Response transformations
($httpProvider.defaults.transformResponse and
$http.defaults.transformResponse):
If XSRF prefix is detected, strip it (see Security Considerations
section below).
If JSON response is detected, deserialize it using a
JSON parser.
I want to POST an Object via JSON to node.js server.
The Object structure is nested, and never succeeded to receive and parse correctly on node.js server site.
EDIT2
I found a solution: see the answer section...
EDIT
I found
console.log(body);
itself output
val1=hello&val2%5Bval3%5D=world
//= {"val1":"hello","val2[val3]":"world"}
weired JSON way
client.js
var data ={val1:"hello",val2:{val3:"world"}};
console.log(data); // -> *1
$.ajax({
url:"/",
type:"POST",
dataType: 'json',
data:data,
success:function (res)
{
resHandler(res);
}
});
*1 ChromeDevelopersTool
Object
val1: "hello"
val2: Object
val3: "world"
server.js
var onreq = function (req, res)
{
if(req.method == 'POST')
{
var body = '';
req.on('data', function (data)
{
body += data;
});
req.on('end', function ()
{
var json = qs.parse(body);
console.log(json.val1); //hello
console.log(json.val2); //undefined
console.log(json.val3); //undefined
console.log(JSON.stringify(json));
//{"val1":"hello","val2[val3]":"world"}
});
}
I understand
val2[val3]
is
val2.val3
However,
Problem 1
JSON.stringify prints out
{"val1":"hello","val2[val3]":"world"}
not
{val1:"hello",val2:{val3:"world"}}
It's ugly, and I don't know why it's like that.
Problem 2
I can never get {val3:"world"}
console.log(json.val3); //undefined
Anyone can explain, and how can I POST a nested JSON to node.js server?
Thanks.
Do NOT use JSON typed data on jQuery Ajax, instead use Stringified JSON
