Is there a way to convert or store this result in a JavaScript array?
var dis = ["The Walt Disney Company","Entertainment",.1]
I need to be able to manipulate the data at one point and add the new data to the visualization.
Data from one of multiple queries --> Convert to array --> Manipulate data ex: multiplying an input --> data.addRows(manipulated input);
Your query does return a string containing JSON wrapped in a function call:
var responseText = 'google.visualization.Query.setResponse({…});';
This is because you specified out: as an argument for tqx (see Google Developers guides).
If you want it all raw, you can extract and parse the JSON of multiple queries and push the data to an array, so you end up with an array of arrays of row data. For your single query, you could start from something like this:
responseJSON = JSON.parse(
responseText.replace(/(^google\.visualization\.Query\.setResponse\(|\);$)/g,'')
);
var rowsArray = [];
responseJSON.table.rows.forEach(function(row){
var rowArray = [];
row.c.forEach(function(prop){ rowArray.push(prop.v); });
rowsArray.push(rowArray);
});
console.log(rowsArray); // === [["The Walt Disney Company", "Entertainment", 0.1]]
There is a more straightforward solution to this. What you get in the response is a JSONP string whose data is hold within a callback function, just as #dakab has mentioned.
Besides this, recently Google has included some extra text in the response to help with some anti-content-sniffing protections to their API. You can read more about this in this Github thread. The response you get now is an unparseable string in this form:
/*O_o*/
google.visualization.Query.setResponse({…});
One way to deal with both issues (the "comment" string and the data hidden inside the callback function) is to evaluate the function. Whether this is risky or not is something intrinsic to the JSONP format, so you must be aware of where your response comes from and decide if it's worth the risk. But, considering it comes from a request to a Google server, and in terms of parsing, it works.
So in your case, what you could do is just declare the callback function (note that you can pass your own function name in the query string, as also mentioned in the Google Developers guides) and then evaluate it. I take inspiration on this thread:
//Declare your call back function
function callback(data){
return data;
}
//Evaluate and store the data in your callback function
var result = eval(UrlFetchApp.fetch(url + uri, options).getContentText());
In "result" you'll have an already parsed JSON that you can convert to whatever you wish.
According to Google's documentation on their Visualization API for response formats, you can add a header in your request that will return JSON without the function or comment.
If you add a header named X-DataSource-Auth in your request, the Visualization API will respond in JSON format rather than JSONP format, which is the default format of the response and includes the JSON wrapped in a function handler.
However, even with this header present, the API prepends a strange string to the response: )]}' which I think has to do with the anti-content-sniffing mentioned by #Diego. Okay, Google — even with an OAuth token do you really need to do that?
So, to get at the actual JSON in that response, you can use the following Javascript to get around it. Assume responseBody is what the API actually returns to you, and that data is storing the JSON you want.
var data = JSON.parse(responseBody.replace(/^\)]\}'\n/, ''));
Assuming str is the returned JSONP formatted response:
var str = `/*O_o*/
google.visualization.Query.setResponse({"version":"0.6","reqId":"0","status":"ok","sig":"403123069","table":{"cols":[{"id":"A","label":"Timestamp","type":"datetime","pattern":"dd/MM/yyyy HH:mm:ss"},{"id":"B","label":"AskGod Search Query","type":"string"}],"rows":[{"c":[{"v":"Date(2020,9,25,12,30,5)","f":"25/10/2020 12:30:05"},{"v":"لا أعرف لماذا"}]}],"parsedNumHeaders":1}});`
console.log(JSON.parse(str.match(/(?<=.*\().*(?=\);)/s)[0]))
I have a javascript function that calls an external program and I need to put the result into an object, which will contain multiple rows with multiple values for each, example below:
$.get(programcall , function(data) {
var dealers = {};
data = {0:{'name':'name1','address':'address1','phone':'phone1','miles':1.2},1:{'name':'name2','address':'address2','phone':'phone2','miles':2.2}};
dealers = data;
});
This test works because "data" is not enclosed in quotes, however when the content of "data" is returned from the called program, it just becomes text content in "dealers".
How can I get the value stored as an object?
The called program is MINE, so I can change the format if necessary to make it work.
The data will be a list of customers with name, address etc, which I want to process using javascript and to populate a DIV.
If the string is valid JSON, use the native JSON.parse function to turn it into an object.
For example:
data = JSON.parse('{"mything": 3}')
One thing to look out for: JSON needs double quotes around key names, so {"mything": 3} works but {'mything': 3} will not validate.
Your external server call is returning string content as the data object. This is, hopefully, a valid JSON format but it is still just a string.
What you probably want to do is use jQuery's getJSON function instead of a simple $.get, since it will take care of converting the response to a JSON object similar to your example.
$.getJSON(programcall, function(data) {
// data is now a JSON object not a string, if it's valid json from your server response
I need to transfer a multi-dimensional JavaScript array to another page, without using any library. What I can use is JavaScript, PHP and other languages that doesn't need a library.
I have a three-dimensional array which is build like this:
storage[category][field][multiple answers] and has a lot of values.
I need to transfer it to another page so I can get all the values like:
alert(storage[5][4][8]);
=======================================================================
Well, I can pass a normal variable to another page but I cant get the values from my array when I'm testing: storage[1][1][1] for example.The big question is how I can pass a multidimensional array to another page and still be able to get the values like this: storage[1][1][1]
As I get it I'm forced to pass all the 121 arrays you can se below to be able to access all dimensions in the array.
My array is built up like this:
storage = new Array();
for (var i1=1;i1<12;i1++){
storage[i1] = new Array();
for (var i2=1;i2<12;i2++){
storage[i1][i2] = new Array();
}
}
Without using a library like jQuery, you can convert your array to JSON, pass it via a URL and decode it on the target page. Converting it to JSON would look like:
var json_string = JSON.stringify(your_array);
Then pass it in a URL:
var your_url = "http://www.your_website.com/page.html?json_string=" + json_string;
And you could decode it back to an array like so:
var your_new_array = JSON.parse(getUrlVars()["json_string"]);
For some more reading, check out this JSON page: http://www.json.org/js.html
JSON.stringify() is supported by all major browsers. Send it to the server via a POST, then have your php retrieve the variable from $_POST and send it back.
As far as I can see there are two main ways to do what you want:
Pass the array to the webserver, and have it send it back on next request.
Store the data locally in the browser.
The first way could get pretty complicated. You would have to store the data in a database, file or cookie/session.
The second way would be the easiest. Use javascript to store the array in the browser. You can either use a cookie, or use the localStorage object.
Using a cookie would require you to serialize the data manually. It would also get passed to the server, so if you want to save bandwidth, you would want to avoid this.
The localStorage method would only store the data locally, and you also don't need to serialize anything, the browser takes care of this for you.

I have a servlet application that takes the user input from HTML form , extracts the required data from backend and makes graphs/charts and shows them to user.
The problem I am seeing is that if user selects first option from dropdown, everything works fine, the data is extracted from backend - I can see it in the AJAX response in firebug and then its parsed by json and then maps are created.
The data that is received from backend is (what I see in AJAX response):
{"responseStr":"[47.636597,-122.189495,0,1,47.643647,-122.212038,0,26,47.505288,-122.339112,0,1,47.622741,-122.314592,0,60,47.541612,-122.129318,0,1,47.568435,-122.161237,0,166,47.682308,-122.196004,0,2,47.666673,-122.284099,0,1,47.612953,-122.316700,0,2,47.600605,-122.322286,0,30,47.589557,-122.315608,0,27,47.636351,-122.327213,0,1,47.630270,-122.177084,2,0,47.630432,-122.140126,17,0,47.621644,-122.132080,1,3,47.630808,-122.153539,86,75,47.622367,-122.337023,495,3466,47.630886,-122.306255,1423,45,47.720287,-122.090885,255,82,47.702376,-122.093340,47,4,47.676897,-122.318752,1,0,47.760994,-122.322550,1,2,47.588854,-122.221273,1,0,39.530179,-119.818395,1,1,47.631306,-122.342762,1,0,47.737242,-122.323710,1,0,47.747054,-122.305083,2,0,47.752018,-122.316452,1,0]"}
This is then parsed in json via
function Respond(REQ){
var res = JSON.parse(REQ.responseText);
var myArr = JSON.parse(res.responseStr);
//forward myArr for processing
}
Now when the same user selects option 2, all works fine, the data is extracted from backend and I can see the following in the response
{"responseStr":"[00:00:00-01:00:00,100,30,0,01:00:00-02:00:00,100,29,0,02:00:00-03:00:00,100,34,0,03:00:00-04:00:00,100,5,0,04:00:00-05:00:00,100,7,0,05:00:00-06:00:00,100,23,0,06:00:00-07:00:00,78,29,0,07:00:00-08:00:00,48,17,0,08:00:00-09:00:00,24,35,0,09:00:00-10:00:00,18,29,0,10:00:00-11:00:00,5,28,0,11:00:00-12:00:00,45,57,0,12:00:00-13:00:00,65,69,0,13:00:00-14:00:00,64,58,0,14:00:00-15:00:00,73,46,0,15:00:00-16:00:00,72,27,0,16:00:00-17:00:00,94,9,0,17:00:00-18:00:00,69,15,0,18:00:00-19:00:00,14,9,0,19:00:00-20:00:00,25,13,0,20:00:00-21:00:00,81,38,0,21:00:00-22:00:00,53,74,0,22:00:00-23:00:00,76,55,0,23:00:00-24:00:00,89,16,0]"}
but when it comes to parse this via
function Respond(REQ){
var res = JSON.parse(REQ.responseText);
var myArr = JSON.parse(res.responseStr);
//forward myArr for processing
}
something wrong happens at line 2 of the function and hence user does not see a chart.
If I were to put alerts in Respond function,
function Respond(REQ){
var res = JSON.parse(REQ.responseText);
alert('here');
var myArr = JSON.parse(res.responseStr);
alert('here2');
//forward myArr for processing
}
then I do see first alert, but not the second. However, for the first case, i see both the alerts. So there is definitely something wrong on line 2. Can someone identify this by looking at the AJAX reponse?
It's looking like this is a problem on the server side, not on the Javascript side. When JSON.parse() tries to crunch the value of responseStr, it looks at the first value in the array, which is 00:00:00-01:00:00. As this not in quotes, it's not a valid string, nor is it a valid number, and so JSON.parse is failing. (In the first example, every response value is a valid floating-point number, which is why it works.)
Also, you're currently parsing JSON twice, once as part of the jQuery ajax request, and again with the the string contained in that object. Though there's nothing inherently wrong with that, it is slower and can create bugs. You should be able to encode everything into a single JSON string on the server side, and then just use the object directly in your Javascript.
Allrit, so in order to make the above a valid string, each of the 00:00:00-01:00:00 (similar ) strings should be enclosed in double quotes. So at a place in my servlet that was fetching this data from database, earlier I was doing
resultSet.getString(1);
now I changed it to
"\"" + resultSet.getString(1)+ "\"";
and it works.
I currently have the following javascript array:
var stuffs = ['a', 'b'];
I pass the above to the server code using jQuery's load:
var data = {
'stuffs': stuffs
};
$(".output").load("/my-server-code/", data, function() {
});
On the server side, if I print the content of request.POST(I'm currently using Django), I get:
'stuffs[]': [u'a', u'b']
Notice the [] at the prefix of the variable name stuffs. Is there a way to remove that [] before it reaches the server code?
This is default behavior in jQuery 1.4+...if you want the post to be &stuffs=a&stuffs=b instead of &stuffs[]=a&stuffs[]=b you should set the traditional option to true, like this:
$.ajaxSetup({traditional: true});
Note this affects all requests... which is usually what you want in this case. If you want it to be per-request you should use the longer $.ajax() call and set traditional: true there. You can find more info about traditional in the $.param() documentation.
When an array is submitted using a GET request, through a form or AJAX, each element is given the name of the array, followed by a pair of optionally empty square brackets. So the jQuery is generating the url http://example.com/get.php?stuff[]=a&stuff[]=b. This is the only way of submitting an array, and the javascript is following the standard.
POST requests work in exactly the same way (unless the json is sent as one long json string).
In PHP, this is parsed back into the original array, so although the query string can be a little strange, the data is recieved as it was sent. $_GET['stuff'][0] works correctly in PHP.
I'm not sure how Django parses query strings.
The [] indicates that the variable is an array. I imagine that the appending of the [] to your variable name is Python/Django's way of telling you it is an array. You could probably implement your own print function which does not show them.
