I have a JS String, like so:
user_fav = "21,16";
This has to go thru a function where it becomes a JSON array with an id key, like so:
{"id":21},{"id":16}
And this goes into an $http request:
return $http({
method: 'GET',
url: getUrl('products'),
params: {
pageSize: 2000,
pageNumber: 1,
"filter": { "q": { "$or": [{"id":21},{"id":16}] } }, // <-- HERE
sort: []
}
});
Now if I run the above $http request everything works fine, but if I convert the String (user_fav) into that JSON and send this to the $http request it fires an error. This is my converter:
user_fav = "21,16";
var user_fav_to_array = "";
var splitFav = user_fav.split(",");
for (var i = 0; i < splitFav.length; i++) {
user_fav_to_array += JSON.stringify({ id: parseInt(splitFav[i]) }) + ',';
}
var JSONFavs = user_fav_to_array.substring(0, user_fav_to_array.length - 1);
//Result: JSONFavs => {"id":21},{"id":16}
So this gives an error:
return $http({
method: 'GET',
url: getUrl('products'),
params: {
pageSize: 2000,
pageNumber: 1,
"filter": { "q": { "$or": [JSONFavs] } }, // <-- HERE
sort: []
}
});
Madame and messier the error is 417 (Critical Exception), this is coming from the Backand.com syste
Have a look at the code below. What your code actually doing is assigning a Json STRING to $or property. But really needed is to assign array of items (as expected). Let me know if you have any questions
user_fav = "21,16";
//Dont need this
//var user_fav_to_array = "";
// New Variable to save array items
var arrayData =[];
var splitFav = user_fav.split(",");
for (var i = 0; i < splitFav.length; i++) {
// don't need this
//user_fav_to_array += JSON.stringify({ id: parseInt(splitFav[i]) }) + ',';
// Just create a simple javascript object with id and put it into array at i index
arrayData[i]={ id: parseInt(splitFav[i]) };
}
//var JSONFavs = user_fav_to_array.substring(0, user_fav_to_array.length - 1);
// Then in Http Request filter, it should be just like this "$or": arrayData
"filter": { "q": { "$or": arrayData } }
This might have to deal with your variable - var user_fav_to_array = "";
You may want to change it to the following var user_fav_to_array = [];
Since it has the quotations it may be causing your variable to behave in a way that you don't want it to. Unless strings are treated as arrays in javascript.

I'm trying to get JSON data by field name like this data.name and it return the desired data, but I have 25 fields in the array and I want to make this dynamically, using data + "." + variable, when I alert it returns [Object object].name, so how I can make it executable?
I tried many ways but all failed, please help me doing this.

This should work. I changed the dot notation while accessing the object property.

jid = (result[i].id.substring(3));
var resulting = responseData[jid];
alert(resulting);

Try giving data[0][jid], we can give a variable in brackets also inorder to get the data
Hope it works
If do foo.bar you are getting a property with the name 'bar' on object foo. If you have some variable const bar = "qux" and you want to access property on some object with the same name as bar value /"qux"/ you just need to use square brackets - foo [bar], which will be the same as calling foo.qux; So, in your case you just need to use data[0][jid] instead of data [0].jid, supposing jid contains a string that is also a key in data[0].
You can just do data[0][variableName] and this will return the data you want. for example. If data had a json string [{ "Name" : "Jane Doe"}] You could execute it like this.
var variableName = "Name";
console.log(data[0][variableName])
This would return "Jane Doe".
if you have your field names in an array you can loop through them using $.each or a for loop.
For example say your json string is [{"First_Name" : "Jane", "Last_Name" : "Doe", "Age" : 32}] you could get all the values from the json string doing this.
var FieldNames = ["First_Name" , "Last_Name", "Age"]
$.each(FieldNames, function(i,item) {
console.log(data[0][item])
}
OR
var FieldNames = ["First_Name" , "Last_Name", "Age"]
for(var i = 0; i < FieldNames.length; i++) {
console.log(data[0][FieldNames[i]])
}
My coldfusion component is returning a JSON format data. I am trying to access the values of that data in my front-end using Javascript. Can someone help me understand how to access the data values such as the "id", "firs_name" and "last_name"?
I am storing the the follow data in the variable called tempData. Below is the JSON structure I am getting:
{ "COLUMNS" : [ "id",
"FIRST_NAME",
"LAST_NAME"
],
"DATA" : [ [ "xxxx",
"Jes",
"Abr"
],
[ "xxx2",
"JESSIE",
"YU"
]
]
}
Below is my ajax call:
$.ajax({
type: "get",
url: "GROUPSLIST.cfc",
data: {
method: "getNames",
queryString: selectQuery
},
success: function(a) {
alert(a);
},
error: function(a) {
alert(a.responseText);
}
});
I am assuming your response is not parsed already. You can use something like following.
var tempData = '{"COLUMNS":["id","FIRST_NAME","LAST_NAME"],"DATA":[["xxxx","Jes","Abr"],["xxx2","JESSIE","YU"]]}';
//parse response if not already parsed
var respObj = JSON.parse(tempData);
var columns = respObj['COLUMNS'];
//create a column map to index like following
var colMap = {};
for(i = 0; i < columns.length; i++){
colMap[columns[i]] = i;
}
console.log(colMap)
var data = respObj['DATA'];
var text = ''
//use data[i][colMap['id']] to access data inside loop.
for(i = 0; i < data.length; i++){
text += data[i][colMap['id']] + ':' +data[i][colMap['FIRST_NAME']] + ' ' + data[i][colMap['LAST_NAME']] + '<br>';
}
document.getElementById('text').innerHTML = text;
<div id="text"></div>
This might be also help full while using DB query and access by column(ex:employee_id,employee_name)
Step-1
// return in serializeJSON format with true
<cffunction name="employeelistJson" returntype="any" returnformat="JSON">
<cfquery name="employeelist" datasource="yourdatasource">
select * from employee
</cfquery>
<cfset setJson = #serializeJSON(employeelist,true)#>
<cfreturn setJson />
</cffunction>
Step-2 access json data by name
success: function(response) {
//must be in caps
alert(response.DATA['EMPLOYEEID']);
alert(response.DATA['EMPLOYEENAME']);
},
Controller sends a JSON for one Frame. I need to keep incrementing the array where Multiple Frame's score gets added. For example
FrameScore = f1 + f2 +.. lastF
Issue The values do not get added and shows data for each Frame only. Where am I doing it wrong?
var bowlingData = {
"frames": []
};
var frames = [];
$('#submitButton').click(function(e) {
frames.push([$("#FirstRoll").val(), $("#SecondRoll").val()]);
for (var ln = 0; ln < frames.length; ln++) {
var temp = {
"firstroll": $("#FirstRoll").val(),
"secondroll": $("#SecondRoll").val()
};
bowlingData.frames.push(temp);
}
console.log("temp data: " + temp);
bowlingData.frames.push(temp);
var element = this;
$.ajax({
url: "/Home/Submit",
type: "POST",
data: JSON.stringify(bowlingData),
dataType: "json",
traditional: true,
contentType: "application/json; charset=utf-8",
success: function(data) {
var parseData = JSON.parse(data);
console.log("MyDate: " + data.score);
console.log("Parse" + parseData);
$("#lblTotalScore").text(parseData.score);
$("#FirstRoll").val("");
$("#SecondRoll").val("");
},
error: function() {
alert("An error has occured!!!");
}
});
});
Apparently the solution is
var frameArray= [];
frameArray.push("#FirstRoll");
frameArray.push("#SecondRoll");
But that is to add single elements to the array. If the input is [[2, 3],[4, 5],...] then the JSON object representation would be
{ "frames": [{"first": 2, "second": 3}, {"first": 4, "second": 5}, ... ] }
However, there was another issue of not getting the correct response from the controller.
The issue here is that an empty array is created (i.e. frames) and on the 3rd line the value was pused to the empty Array. Although the the for loop was adding each element to the Array(i.e. frames) but when the response was created the recent input was replacing the previous input, because the JSON object bowlingData was holding temp data only. So no need to create any Array to increment multiple input result. Initial value would be hold by the browser and second input would be added in next submit.
Was
var frames = [];
$('#submitButton').click(function(e) {
frames.push([$("#FirstRoll").val(), $("#SecondRoll").val()]);
for (var ln = 0; ln < frames.length; ln++) {
var temp = {
"firstroll": $("#FirstRoll").val(),
"secondroll": $("#SecondRoll").val()
};
bowlingData.frames.push(temp);
}
Should be
$('#submitButton').click(function (e) {
bowlingData.frames.push({
"firstroll": $("#FirstRoll").val(),
"secondroll": $("#SecondRoll").val()
});
I have a json file that contains 16,490 lines of data. Here's a snippet:
[
...
["alrightty",2 ],
["alrighttyy",1 ],
["alrighty",100 ],
["alrightyy",1 ],
["alrigt",1 ],
...
]
This data will be used for my sentiment analysis thesis project. I used the following code to extract the data from the json file:
var positive_words_list = {}
function readJSONFile(filename,type) {
$.ajax({
type: 'GET',
url: filename,
dataType: 'json',
success: function(data) {
switch (type) {
case "pos" : positive_words = data; break;
case "neg" : negative_words = data; break;
case "afinn" : afinn_words = data; break;
}
},
async: false
});
}
readJSONFile('js/json/positivekeywords.json','pos');
for (var i = 0; i < positive_words.length; i++) {
row = positive_words[i];
positive_words_list[row[0]] = row[1];
};
What this code does is extract the data from the json file and then put it in a 1-dimensional array with each word as an array index and the number as the value.
Now I have this code run when the site loads inside $(function() { ... }); so positive_words_list should contain the data on load time. The thing is after the site loads and I do positive_words_list.length in the console, it outputs 63. As I said, there should be 16,490 entries.
Did I miss something? What am I doing wrong?
Thanks!
John
EDIT: I should add that when I do a positive_words.length in the console, I get the correct number of elements, 164,950
As far as I can see positive_words_list is a JavaScript object that does not have length property out of the box. So the only reason why you get the magic number 63 is because your array of arrays contain entity with word length as a first item; something like:
[
...
['length', 63],
...
]
In order to get number of keys in JavaScript Object you can either do Object.keys(positive_words_list).length or iterate over all properties and increment the counter:
function size(obj) {
var key,
counter = 0;
for(key in obj) {
if(obj.hasOwnProperty(key)) {
counter++;
}
}
return counter;
}
size(positive_words_list); // <- will return number of properties in object
Your snippet may be modified in the following manner:
HTML
<h1 id="data">Number of positive words is ...</h1>
JavaScript
$(function(){
var positive_words,
positive_words_list = {};
function readJSONFile(filename,type) {
$.ajax({
type: 'GET',
url: filename,
dataType: 'json',
success: function(data) {
switch (type) {
case "pos" : positive_words = data; break;
case "neg" : negative_words = data; break;
case "afinn" : afinn_words = data; break;
}
},
async: false
});
}
readJSONFile('data.json','pos');
for (var i = 0; i < positive_words.length; i++) {
row = positive_words[i];
positive_words_list[row[0]] = row[1];
};
$('#data').html('Number of positive words is ' + Object.keys(positive_words_list).length);
});
Plunker: http://plnkr.co/edit/uhHZ1zEuUHXHIQrd1BVa?p=preview
positive_words_list is an object, not an array, so you should result in:
positive_words_list["alrightty"] === 2
positive_words_list["alrighttyy"] === 1
and so forth. You can get an array of the keys of the object using:
Object.keys(positive_words_list)
Object.keys(positive_words_list).length
Which will return an array of the keys of your object. Note that Object.keys is an ES5 feature available in most current browsers.
am trying to update database.
For that iam doing like this
From js code
var data = {
"jobid": $('#jobid').val(),
"names": $('#names').val(),
"scripttype": $('#testscripts').val()
};
var msg="";
for(i = 1; i <=4; i++) {
data["Param" + i + "Key"] = $('#key' + i).val();
data["Param" + i + "Value"] = $('#value' + i).val();
}
$.ajax({
type: 'post',
url: "/save",
dataType: "json",
data: data
});
in node.js side
jobsCollection.update({
_id: id
}, {
$set: {
names: record.names,
script: record.scripttype,
// i dont know what should i place in this part???
// i have to set paramkey and paramValues
}
},
{
upsert: true
},
function (err, result) {
if (!err) return context.sendJson([], 404);
});
in record.names and record.scripttype getting proper values.
I don't know how to set values got from the for loop for updating
request going
Request: /save
{ jobid: '',
names: 'first',
scripttype: 'fow',
Param1Key: '1',
Param1Value: 'oneeeeee',
Param2Key: '2',
Param2Value: 'twoooooooo'
etc........
............
}
Since the property names are dynamic, you'll need to use the indexer-style property accessor of JavaScript as shown below.
Just reverse the process basically. I'm not sure where the data is located at the point you're calling update, so I called it sourceData in the example below;
// create an object with the well known-property names
var set = {
names : record.names,
script : record.scripttype
};
// now loop through the params and set each one individually
for(i = 1; i <=4; i++) {
var key = "Param" + i + "Key"; // build a key string
set[key] = sourceData[key]; // grab the data and set it
key = "Param" + i + "Value"; // and repeat
set[key] = sourceData[key];
}
then, pass it to your update:
jobsCollection.update({
_id: id
}, {
$set: set // pass the object created above
}, /* etc. */
If you don't know the count of Params, you could:
send it
use instead for .. in to loop through all the properties
For #2:
for(var key in sourceData) {
// you could filter the property names here if you'd like
// (like if only Params# were important)
set[key] = sourceData[key];
}
