how to get js var data from GDownloadUrl callback? - javascript

Now, I have tried to get some data from crawling website.
The target website provides current status of bicycle stations using google map.
GDownloadUrl("/mapAction.do?process=statusMapView", function(data, responseCode) {
var jsonData = eval("(" + data + ")");
//alert(jsonData.centerLat);
var length = jsonData.markers.length;
//if (length > 100) length = 100;
for (var i = 0; i < length; i++) {
var point = new GLatLng(parseFloat(jsonData.markers[i].lat), parseFloat(jsonData.markers[i].lng));
var name = jsonData.markers[i].name;
var cntRackTotal = jsonData.markers[i].cntRackTotal;
var cntRentable = jsonData.markers[i].cntRentable;
var cntLockOff = jsonData.markers[i].cntLockOff;
var cntPrtRack = jsonData.markers[i].cntPrtRack;
var percent = jsonData.markers[i].percent;
var imgFile = jsonData.markers[i].imgFile;
var number = jsonData.markers[i].kiosk_no;
//map.addOverlay(createMarker(number, point, name, cntRackTotal, cntRentable, cntLockOff, cntPrtRack, percent, imgFile ));
}
});
This JS source code is used on target website. In GDownloadUrl callback function, the parameter "data" contains current status of bicycle stations. And I want to get data.
Now, I tried using python selenium and execute_script().
jsSourcecode = ("var strData;"+
"strData = GDownloadUrl('/mapAction.do?process=statusMapView',"+
" function(data, responseCode) {return data;}); return strData;")
data = driver.execute_script(jsSourcecode)
this source code is that I used to get data. I expected data on callback would be stored on var strData and the return value of execute_script() would be the data. but the return value is just "True".
I have little knowledge about js.. How can I get the data? Please help

The function you are calling is asynchronous and requires a callback function as argument.
Use execute_async_script and provide the callback present in the last argument:
data, status = driver.execute_async_script("""
var callback = arguments[0];
window.GDownloadUrl('/mapAction.do?process=statusMapView', function(data, status){
callback([data, status]);
});
""")

How can I solve data range error into google sheets with appscript

I have a google app script that allows me to retrieve data via a public API and a fetch. So far so good. I initialized a table in order to push the data into it, then I call a function that will send the data to a column of my google sheets table. My first function fills the array with a "while" loop, when the length of the array reaches 12, my "pushDatasToSheet" function launches but I have an error, the console tells me that my data range is at 1 and therefore does not correspond not in range of my selected cells. What is funny is that my table does indeed indicate a length of 12 when executing my function sending data to the table and when I modify the range of my cells by putting only one , the console shows me 12 for my data range. I can't find where my mistake is coming from. thank you in advance for your help.
Here an image of the console error:
error code in app script console
And my code:
const signsList = ["aries", "taurus", "gemini", "cancer", "leo", "virgo", "libra", "scorpio", "sagittarius", "capricorn", "aquarius", "pisces"];
var SHEET_NAME = "horoscope";
const options = {
'method': 'post',
};
var rowDescription = [];
// Get horoscopes from API
function doPost(e) {
signsList.forEach(sign => {
while (rowDescription.length < 12) {
var url = 'https://aztro.sameerkumar.website/?sign=' + sign + '&day=today';
var response = UrlFetchApp.fetch(url, options);
var json = response.getContentText();
var data = JSON.parse(json);
rowDescription.push(data.description);
}
pushDatasToSheet();
})
}
function pushDatasToSheet() {
Logger.log(rowDescription.length);
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(SHEET_NAME);
var descriptionColumn = sheet.getRange('B2:B13');
descriptionColumn.setValues([rowDescription]);
};
Problem solved 😅
In case another person with the same problem happen, the array have to be a 2D array. And i have changed my while loop for a if statement.
Here the correction snippet:
const signsList = ["aries", "taurus", "gemini", "cancer", "leo", "virgo", "libra", "scorpio", "sagittarius", "capricorn", "aquarius", "pisces"];
var SHEET_NAME = "horoscope";
const options = {
'method': 'post',
};
var rowDescription = [];
// Get horoscopes from API
function doPost(e) {
if (rowDescription.length < 12) {
signsList.forEach(sign => {
var url = 'https://aztro.sameerkumar.website/?sign=' + sign + '&day=today';
var response = UrlFetchApp.fetch(url, options);
var json = response.getContentText();
var data = JSON.parse(json);
rowDescription.push([data.description]);
})
}
pushDatasToSheet();
}
function pushDatasToSheet() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(SHEET_NAME);
sheet.getRange('B2:B13').setValues(rowDescription);
};

How do I use two variables in my function?

So I have multiple script. One script retrieves data from a Googlesheet and parses it as JSON. The other one uses this to output it to HTML.
My first:
function getStatistics() {
var sheet = SpreadsheetApp.openById("ID");
var rowsData = sheet.getRange("A:A").getValues();
var result = JSON.stringify(rowsData);
var funcNumber = 1;
return result;
}
This retrieves the data from a spreadsheet in column A.
The second script, here I want to use both 'Result' and 'Funcnumber' in my function.
function onSuccess(data, funcNumber) {
var dataJson = JSON.parse(data);
var newColumn = document.createElement("div");
newColumn.className = "column";
for(var i = 0; i < dataJson.length; i++) {
if (dataJson[i] != "") {
var div = document.getElementById('cont-' + funcNumber);
var newDiv = document.createElement("div");
newDiv.innerHTML = dataJson[i];
newColumn.appendChild(newDiv);
}
}
div.appendChild(newColumn);
}
Using the Json result to PARSE the HTML works. But retrieving 'funcNumber' from the function not. Then finally I call the first function with this line:
google.script.run.withSuccessHandler(onSuccess).getStatistics();
Does anybody know how to use both result and funcNumber in my second function?
function getStatistics() {
var ss = SpreadsheetApp.openById("ID");
const sheet = ss.getSheetByName('Sheet1');
let result = {data:JSON.stringify(sheet.getRange(1,1,sheet.getLastRow(),1).getValues()),funcNumber:1}
return result;
}
function onSuccess(obj) {
var dataJson = JSON.parse(obj.data).flat();
var newColumn = document.createElement("div");
newColumn.className = "column";
for (var i = 0; i < dataJson.length; i++) {
if (dataJson[i] != "") {
var div = document.getElementById('cont-' + obj.funcNumber);
var newDiv = document.createElement("div");
newDiv.innerHTML = dataJson[i];
newColumn.appendChild(newDiv);
}
}
div.appendChild(newColumn);
}
A single column or row is still a 2d array
Following is the way to make the call in Google script to return the value for the 2nd parameter.
google.script.run
.withSuccessHandler(onSuccess)
.withUserObject(funcNumber)
.getStatistics()
WithUserObject() needs to be called after the withSuccessHandler.
See the documentation below on Google script
withUserObject(object)
Sets an object to pass as a second parameter to the success and failure handlers. This "user object" — not to be confused with the User class — lets the callback functions respond to the context in which the client contacted the server. Because user objects are not sent to the server, they are not subject to the restrictions on parameters and return values for server calls. User objects cannot, however, be objects constructed with the new operator.

ServiceNow auto-populate Script not being called

I have a table in ServiceNow that contains Store and a corresponding Tier that is associated with the Store.
I am trying to auto-populate a record producer, once Store is selected. and my script is not running.
The table is a custom table created in a scoped application which is new to me so not sure what I am doing wrong in the scripting. Any advice?
//Catalog Client Script (runs on [Store] Record Producer Change)
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
// new GlideAjax object referencing store of AJAX script include
var ga = new GlideAjax("HRProfileAjax");
// add store parameter to define which function we want to call
// method store in script include will be getFavorites
ga.addParam("sysparm_store", "getHRProfile");
ga.addParam("sysparm_tier", "getHRProfile");
// submit request to server, call ajaxResponse function with server response
ga.getXML(ajaxResponse);
function ajaxResponse(serverResponse) {
// get result element and attributes
var result = serverResponse.responseXML.getElementsByTagstore("result");
var message = result[0].getAttribute("tier");
//check for message attribute and alert user
//if(message)
//alert(message);
//build output to display on client for testing
// get favorite elements
var favorites = serverResponse.responseXML.getElementsByTagstore("favorite");
for(var i = 0; i < favorites.length; i++) {
var store = favorites[i].getAttribute("store");
g_form.setValue(store);
var tier = favorites[i].getAttribute("tier");
//output += store + " = " + tier + "\n";
g_form.setValue(store,tier);
}
//g_form.setValue('number',output);
}

getHRProfile : function() {
// build new response xml element for result
var result = this.newItem("result");
var store = this.getParameter('store');
var hrPro = new GlideRecord('x_hiring_gri_hr_storetier');
hrPro.addQuery('store',store);
hrPro.query();
if(hrPro.next()){

this._addFavorite("tier", hrPro.tier);
}
},

Unexpected token u in JSON at position 0 not working for async

I am fairly new to js and node.js but I have managed to get the calls going to the API and getting the necessary information. However when I was attempting to continue to raise the batter id to get the next information available. I have successfully gotten the undefined error check to work as well. But I was unable to loop through because I was trying to perform something immediately on an async function. I am now trying to make the entire function async with a 2 second delay after each run, but it is returning the following error (i'm assuming because something is undefined)
**Note: When I just get the value for i=4 and p=1 the value does exist in the API data. However it gives this error when I attempt to start with those values using this code.
error:
Unexpected token u in JSON at position 0
this is my code:
request('API Info redacted',
setTimeout (function (err, response, body) {
//do stuff below
//to get the first play of the game, set i=1 and p=0
var i = 4;
var p = 1;
// ************
var boolIn = 1;
// parse the body as JSON
var parsedBody = JSON.parse(body);
var apiResults = parsedBody.apiResults;
if( typeof(apiResults[0].league.season.eventType[0].events[0].pbp[i].pbpDetails[p]) == 'undefined') {
//sets the variables to the first batter of the next inning
p=0;
i = i+1;
}
//below pulls the apiResults from the body of the API request
var sportId = apiResults.sportId;
var hitName = apiResults[0].league.season.eventType[0].events[0].pbp[i].pbpDetails[p].name;
var fname = apiResults[0].league.season.eventType[0].events[0].pbp[i].pbpDetails[p].batter.firstName;
var lname = apiResults[0].league.season.eventType[0].events[0].pbp[i].pbpDetails[p].batter.lastName;
var outsB = apiResults[0].league.season.eventType[0].events[0].pbp[i].pbpDetails[p].outs.before;
var outsA = apiResults[0].league.season.eventType[0].events[0].pbp[i].pbpDetails[p].outs.after;
var rbis = apiResults[0].league.season.eventType[0].events[0].pbp[i].pbpDetails[p].runsBattedIn;
var outDifference = (outsA - outsB);
var hitB = apiResults[0].league.season.eventType[0].events[0].pbp[i].pbpDetails[p].baseSituation.beforeId;
var hitA = apiResults[0].league.season.eventType[0].events[0].pbp[i].pbpDetails[p].baseSituation.afterId;
var baseDifference = (hitA - hitB);
//prints the details pulled above
res.json("First Name: " + fname + ", Last Name: " + lname + ", Hit name: " + hitName + ", Outs on the play: " + outDifference + ", Rbi's: " + rbis +
", Base Sit: " + baseDifference);
//increases the batter call
p = p+1;
//below ends the setTimeout
}, 2000));
//ended request
});
setTimeout will not pass arguments to the function it calls, so body is undefined. When you pass that to JSON.parse, it will be converted to the string "undefined", which isn't a valid JSON text.
Nowhere is your code do you show any JSON coming into your program (or embedded into it). You need to have some JSON to parse before you try to parse it.

ServiceNow UI Page GlideAjax

I created a form using UI Page and am trying to have some fields autopopulated onChange. I have a client script that works for the most part, but the issue arises when certain fields need to be dot-walked in order to be autopopulated. I've read that dot-walking will not work in client scripts for scoped applications and that a GlideAjax code will need to be used instead. I'm not familiar with GlideAjax and Script Includes, can someone help me with transitioning my code?
My current client script looks like this:
function beneficiary_1(){
var usr = g_user.userID;
var related = $('family_member_1').value;
var rec = new GlideRecord('hr_beneficiary');
rec.addQuery('employee',usr);
rec.addQuery('sys_id',related);
rec.query(dataReturned);
}
function dataReturned(rec){
//autopopulate the beneficiary fields pending on the user selection
if(rec.next()) {
$('fm1_ssn').value = rec.ssn;
$('fm1_address').value = rec.beneficiary_contact.address;
$('fm1_email').value = rec.beneficiary_contact.email;
$('fm1_phone').value = rec.beneficiary_contact.mobile_phone;
var dob = rec.date_of_birth;
var arr = dob.split("-");
var date = arr[1] + "/"+ arr[2] + "/" + arr[0] ;
$('fm1_date_of_birth').value = date;
}
}
fm1_address, fm1_email, and fm1_phone do not auto populate because the value is dot walking from the HR_Beneficiary table to the HR_Emergency_Contact table.
How can I transform the above code to GlideAjax format?
I haven't tested this code so you may need to debug it, but hopefully gets you on the right track. However there are a couple of steps for this.
Create a script include that pull the data and send a response to an ajax call.
Call this script include from a client script using GlideAjax.
Handle the AJAX response and populate the form.
This is part of the client script in #2
A couple of good websites to look at for this
GlideAjax documentation for reference
Returning multiple values with GlideAjax
1. Script Include - Here you will create your method to pull the data and respond to an ajax call.
This script include object has the following details
Name: BeneficiaryContact
Parateters:
sysparm_my_userid - user ID of the employee
sysparm_my_relativeid - relative sys_id
Make certain to check "Client callable" in the script include options.
var BeneficiaryContact = Class.create();
BeneficiaryContact.prototype = Object.extendsObject(AbstractAjaxProcessor, {
getContact : function() {
// parameters
var userID = this.getParameter('sysparm_my_userid');
var relativeID = this.getParameter('sysparm_my_relativeid');
// query
var rec = new GlideRecord('hr_beneficiary');
rec.addQuery('employee', userID);
rec.addQuery('sys_id', relativeID);
rec.query();
// build object
var obj = {};
obj.has_value = rec.hasNext(); // set if a record was found
// populate object
if(rec.next()) {
obj.ssn = rec.ssn;
obj.date_of_birth = rec.date_of_birth.toString();
obj.address = rec.beneficiary_contact.address.toString();
obj.email = rec.beneficiary_contact.email.toString();
obj.mobile_phone = rec.beneficiary_contact.mobile_phone.toString();
}
// encode to json
var json = new JSON();
var data = json.encode(obj);
return data;
},
type : "BeneficiaryContact"
});
2. Client Script - Here you will call BeneficiaryContact from #1 with a client script
function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
var usr = g_user.userID;
var related = $('family_member_1').value;
var ga = new GlideAjax('BeneficiaryContact'); // call the object
ga.addParam('sysparm_name', 'getContact'); // call the function
ga.addParam('sysparm_my_userid', usr); // pass in userID
ga.addParam('sysparm_my_relativeid', related); // pass in relative sys_id
ga.getXML(populateBeneficiary);
}
3. Handle AJAX response - Deal with the response from #2
This is part of your client script
Here I put in the answer.has_value check as an example, but you may want to remove that until this works and you're done debugging.
function populateBeneficiary(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
answer = answer.evalJSON(); // convert json in to an object
// check if a value was found
if (answer.has_value) {
var dob = answer.date_of_birth;
var arr = dob.split("-");
var date = arr[1] + "/"+ arr[2] + "/" + arr[0];
$('fm1_ssn').value = answer.ssn;
$('fm1_address').value = answer.address;
$('fm1_email').value = answer.email;
$('fm1_phone').value = answer.mobile_phone;
$('fm1_date_of_birth').value = date;
}
else {
g_form.addErrorMessage('A beneficiary was not found.');
}
}
