I've been trying to create a script which shows Bitcoin and Ethereum price according to users preference. So if an user clicks on bitcoin button it shows bitcoin price and when user clicks on Ethereum button it shows Ethereum.
Everything kind of works but when you click on Bitcoin button and then on Ethereum button it creates a conflict and keeps switching between Bitcoin and Ethereum price.
I have tried to use
pricesWs1.close(); and pricesWs.close(); but it completely closes 1 websocket and you can't swap between the prices.
Javascript
const pricesWs = new WebSocket('wss://ws.coincap.io/prices?assets=bitcoin')
const pricesWs1 = new WebSocket('wss://ws.coincap.io/prices?assets=ethereum')
$(document).ready(function() {
$('.buttonbtc').click(function(e) {
pricesWs.onmessage = function (msg) {
var str = msg.data
var matches = str.match (/\b\d+(?:.\d+)?/);
var finalprice = parseFloat(matches);
document.getElementById("btc").innerHTML = finalprice;
}
});
});
$(document).ready(function() {
$('.buttoneth').click(function(e) {
pricesWs1.onmessage = function (msgg) {
var str = msgg.data
var matches = str.match (/\b\d+(?:.\d+)?/);
var finalprice = parseFloat(matches);
document.getElementById("btc").innerHTML = finalprice;
}
});
});

The problem seems to be that you're getting constant response messages from the coinbase server.
You can prevent the text display from being updated onmessage unless the socket that sent it matches the last clicked button.
In this case I stored the value of the last clicked button in a variable named cp and only update the display on message if it was sent by the corresponding socket.
Code:
const pricesWs = new WebSocket('wss://ws.coincap.io/prices?assets=bitcoin')
const pricesWs1 = new WebSocket('wss://ws.coincap.io/prices?assets=ethereum');
var cp = -1;//current_price
$(document).ready(function() {
$('.buttonbtc').click(function(e) {
cp = 0;
document.getElementById("btc").innerHTML = "pending...";
pricesWs.onmessage = function (msg) {
if(cp == 0) {
var str = msg.data
var matches = str.match (/\b\d+(?:.\d+)?/);
var finalprice = parseFloat(matches);
document.getElementById("btc").innerHTML = finalprice;
}
}
});
});
$(document).ready(function() {
$('.buttoneth').click(function(e) {
cp = 1;
document.getElementById("btc").innerHTML = "pending...";
pricesWs1.onmessage = function (msgg) {
if(cp == 1) {
var str = msgg.data
var matches = str.match (/\b\d+(?:.\d+)?/);
var finalprice = parseFloat(matches);
document.getElementById("btc").innerHTML = finalprice;
}
}
});
});
If you however also want to stop the root cause of the problem(the constant messages being sent by the server) you will need to iniate the socket connection and close the connection after a message (or possibly some configuration with coinbase which will only send back 1 message).
var pricesWs;
var pricesWs1;
const wlist = ['wss://ws.coincap.io/prices?assets=bitcoin',
'wss://ws.coincap.io/prices?assets=ethereum'];
var cp = -1;//current_price
$(document).ready(function() {
$('.buttonbtc').click(function(e) {
cp = 0;
document.getElementById("btc").innerHTML = "pending...";
pricesWs = new WebSocket(wlist[0]);
pricesWs.onopen = function() {
pricesWs.onmessage = function (msg) {
if(cp == 0) {
var str = msg.data
var matches = str.match (/\b\d+(?:.\d+)?/);
var finalprice = parseFloat(matches);
document.getElementById("btc").innerHTML = finalprice;
}
pricesWs.close();
}
}
});
});
$(document).ready(function() {
$('.buttoneth').click(function(e) {
cp = 1;
document.getElementById("btc").innerHTML = "pending...";
pricesWs1 = new WebSocket(wlist[1]);
pricesWs1.onopen = function() {
pricesWs1.onmessage = function (msgg) {
if(cp == 1) {
var str = msgg.data
var matches = str.match (/\b\d+(?:.\d+)?/);
var finalprice = parseFloat(matches);
document.getElementById("btc").innerHTML = finalprice;
}
pricesWs1.close();
}
}
});
});
an additional check can also be added to ensure the sockets are not in the process of being opened when a button is clicked

i'm new in servicenow and I have to add this filter "document_id.number STARTS WITH BKNG"
as a query, how can i do in servicenow?
this is my code:
// only show 30 in header menu dropdown
var max = 30;
var t = data;
t.items = [];
t.count = 0;
var u = getMyApprovals();
// use record watchers to tell header when to update dropdown counts
t.record_watchers = [];
t.record_watchers.push({'table':'sysapproval_approver','filter':'approverIN' + u.toString() + '^state=requested'});
var z = new GlideRecord('sysapproval_approver');
z.addQuery("approver", u);
z.addQuery("state", "requested");
z.addQuery("document_id.number", "STARTSWITH", "BKNG")
z.orderByDesc('sys_updated_on');
z.setLimit(max);
z.query();
var link = {};
link.title = gs.getMessage('View all approvals');
link.type = 'link';
link.href = '?id=approvals';
link.items = [];
t.items.push(link);
while (z.next()) {
var a = {};
var rec = getRecordBeingApproved(z);
if (!rec.isValidRecord()) // nothing being approved - hmmm
continue;
a.short_description = rec.short_description + "";
if (rec.getRecordClassName() == "sc_request") {
var items = new GlideRecord("sc_req_item");
items.addQuery("request", rec.getUniqueValue());
items.query();
if (items.getRowCount() > 1)
a.short_description = items.getRowCount() + " requested items";
else if (items.getRowCount() == 1) {
items.next();
a.short_description = items.getValue("short_description");
}
}
$sp.getRecordValues(a, z, 'sys_id,sys_updated_on');
a.number = rec.getDisplayValue();
a.__table = z.getRecordClassName();
a.type = 'approval';
t.items.push(a);
t.count++;
}
function getRecordBeingApproved(gr) {
if (!gr.sysapproval.nil())
return gr.sysapproval.getRefRecord();
return gr.document_id.getRefRecord();
}
i tried doing z.addQuery ("document_id.number", "STARTSWITH", "BKNG")
but it doesn't works.
i don't know how to do.
You can't dot-walk the document_id field when using .addQuery() as it is not a reference filed. Instead, you can use the Approval for (sysapproval) reference field like so:
z.addQuery("sysapproval.number", "STARTSWITH", "BKNG");
I have a web app with one drop down list and 2 buttons. The drop down list get values from a sheet. The buttons write back in the sheet. The script I have works fine with that:
<script>
$(function() {
$('#txt1').val('');
google.script.run
.withSuccessHandler(updateSelect)
.getSelectOptions();
});
function updateSelect(opt)
{
var select = document.getElementById("sel1");
select.options.length = 0;
for(var i=0;i<opt.length;i++)
{
select.options[i] = new Option(opt[i],opt[i]);
}
}
function listS() {
const selectElem = document.getElementById('sel1')
const index = selectElem.selectedIndex;
if (index > -1) {
const e = document.getElementById("sel1");
const value = e.options[index].value;
const body = { index: index, value: value };
google.script.run.withSuccessHandler(yourCallBack).yourServerSideFunc(body);
}
}
document.getElementById("but1").addEventListener("click",listS);
function yourCallBack(response) {
}
</script>
In Java script:
function getSelectOptions()
{
var ss=SpreadsheetApp.openById('1onuWoUKh1XmvEAmKktwJekD782BFIru-MDA0omqzHjw');
var sh=ss.getSheetByName('Database');
var rg=sh.getRange(2,1,sh.getLastRow()-1,8);
var vA=rg.getValues();
var useremail = Session.getActiveUser().getEmail();
var opt=[];
for(var i=0;i<vA.length;i++)
{
if(vA[i][1] == "Pending Approval"){
if(vA[i][7]+"#xxx.com" == useremail || vA[i][7]+"#xxx.com" == useremail) {
opt.push(vA[i][3]+" REQ ID: "+vA[i][0]);
}
}
};
if (opt.length == 0) {opt.push("You do not have pending requests")};
return opt;
}
function doGet() {
var output = HtmlService.createHtmlOutputFromFile('list');
return output;
}
function yourServerSideFunc(body) {
var value = body["value"];
var ss = SpreadsheetApp.openById('1onuWoUKh1XmvEAmKktwJekD782BFIru-MDA0omqzHjw');
var sh = ss.getSheetByName('Database');
var rg=sh.getRange(1,1,sh.getLastRow()-1,4);
var vA=rg.getValues();
var str = "Approved";
for(var i=0;i<vA.length;i++)
{
if(vA[i][3]+" REQ ID: "+vA[i][0] == value) {
sh.getRange(i+1, 2).setValue(str);
}
};
return ContentService.createTextOutput(JSON.stringify({message: "ok"})).setMimeType(ContentService.MimeType.JSON);
Now I am trying to regenerate the drop down list values after the button is clicked. I tried to add
var output = HtmlService.createHtmlOutputFromFile('list');
return output;
in yourServerSideFunc(body) function to regenerate the HTML but does not work. I have tried to force a HTML refresh, but also did not work.
How can I easily re-trigger the generation of the drop down list items? Worst case scenario it is ok to refresh the whole page, but it should be simple to regenerate the drop down list since I have already the code for it.
I ended up with this work around.
function listS() {
const selectElem = document.getElementById('sel1')
const index = selectElem.selectedIndex;
if (index > -1) {
const e = document.getElementById("sel1");
const value = e.options[index].value;
const body = { index: index, value: value };
google.script.run.withSuccessHandler(yourCallBack).yourServerSideFunc(body);
//ADDED:
var select = document.getElementById("sel1");
select.options[index] = new Option("Approved! Please refresh","Approved! Please refresh");
selectElem.selectedIndex = index;
}
}
It does not really meet the original goal to refresh the list from the sheet. It would be great if someone else posted a solution to call the server function. I tried to add google.script.run.doGet() and similar, but it seems that it does not call the server side functions properly.
I am trying to get specific values from the general site that contains the annual reports of public-listed firms using Selenium Webdriver JS. Kindly help me investigate. I get the issue on clicking the Annual Report link.
The process that I'm trying to automate is listed below:
Go to site (http://edge.pse.com.ph/financialReports/form.do)
Filter by type of report (sendKeys('Annual Report') and fromDate attribute value to 4-23-2012 (year 2012 to get 4-5 annual reports of each firm)
click btnSearch
click Annual Report link per company row to view report (a tag is inside a td)
switch to the popup window
get specific values as object values and store it in the array
close popup window and get back to initial window
Repeat it on the succeeding company rows (take note that the site has pagination and a total of 22 pages (or tables) must be looped through
Kindly check my initial code for the process below. I also think that my implicitWaits are working. Does it apply on Selenium executeScript commands?

I'm getting HTML from a forum url, and parsing the post count of the user from their profile page. I don't know how to write the parsed number into the Google spreadsheet.
It should go account by account in column B till last row and update the column A with count.
The script doesn't give me any errors, but it doesn't set the retrieved value into the spreadsheet.
function msg(message){
Browser.msgBox(message);

var sliced = html.slice(0,html.search('Posts Per Day'));
sliced = sliced.slice(sliced.search('<dt>Total Posts</dt>'),sliced.length);
postCount = sliced.slice(sliced.search("<dd> ")+"<dd> ".length,sliced.search("</dd>"));
return postCount;

The is the first time I'm doing something like this and working from an example from other site.
I have one more question. In function getPostCount I send the function profileurl. Where do I declare that ?
Here is how you get the URL out of the spreadsheet:
function getPostCount(profileUrl){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var thisSheet = ss.getSheetByName("List1");
var getNumberOfRows = thisSheet.getLastRow();
var urlProfile = "";
var sliced = "";
var A_Column = "";
var arrayIndex = 0;
var rngA2Bx = thisSheet.getRange(2, 2, getNumberOfRows, 1).getValues();
for (var i = 2; i < getNumberOfRows + 1; i++) { //Start getting urls from row 2
//Logger.log('count i: ' + i);
arrayIndex = i-2;
urlProfile = rngA2Bx[arrayIndex][0];
//Logger.log('urlProfile: ' + urlProfile);
var html = UrlFetchApp.fetch(urlProfile).getContentText();
sliced = html.slice(0,html.search('Posts Per Day'));
var postCount = sliced.slice(sliced.search("<dd> ")+"<dd> ".length,sliced.search("</dd>"));
sliced = sliced.slice(sliced.search('<dt>Total Posts</dt>'),sliced.length);
postCount = sliced.slice(sliced.search("<dd> ")+"<dd> ".length,sliced.search("</dd>"));
Logger.log('postCount: ' + postCount);
A_Column = thisSheet.getRange(i, 1);
A_Column.setValue(postCount);
};
}
You're missing var in front of one of your variables:
postCount = sliced.slice(sliced.search("<dd> ")+"<dd> ".length,sliced.search("</dd>"));
That won't work. Need to put var in front. var postCount = ....
In this function:
function updatePosts(){
if(arguments[0]===false){
showAlert = false;
} else {
showAlert=true;
}
There is no array named arguments anywhere in your code. Where is arguments defined and how is it getting any values put into it?
I need some help on an assignment that I need to do. Basically the question is a number guessing game. We're assigned a number in the interval [0,1023] based on our student number and we have 11 guesses to get the right number. I know I have to use a binary search to get the number, my only problem is connecting to the server and getting a result.
We're given this:
A sample request looks as follows:
http://142.132.145.50/A3Server/NumberGuess?snum=1234567&callback=processResult&guess=800
And also given that the request returns the following parameters:
1: A code to determine if your guess is equal, less than or greater than the number
2: Message string
3: Number of guesses made by my application
This is what I've tried so far, just as a test to get the server request working. All I get in return is "object HTMLHeadingElement"
window.onload = function() {
newGuess();
}
function newGuess() {
var url = "http://142.132.145.50/A3Server/NumberGuess?snum=3057267&callback=processResult&guess=600";
var newScriptElement = document.createElement("script");
newScriptElement.setAttribute("src", url);
newScriptElement.setAttribute("id", "jsonp");
var oldScriptElement = document.getElementById("jsonp");
var head=document.getElementsByTagName("head")[0];
if (oldScriptElement == null) {
head.appendChild(newScriptElement);
} else {
head.replaceChild(newScriptElement, oldScriptElement);
}
}
function processResult(code,message,guesses) {
var code = document.getElementById("code");
var message = document.getElementById("message");
var guesses = document.getElementById("guesses");
code.innerHTML = code;
message.innerHTML = message;
guesses.innerHTML = guesses;
}
EDIT: Current state of my code.
window.onload = function() {
min = 0;
max = 1023;
mid = 0;
setInterval(newGuess,1000);
};
function newGuess() {
mid = Math.floor((max-min)/2);
var url = "http://142.132.145.50/A3Server/NumberGuess?snum=3057267&callback=processResult&guess="+mid;
var newScriptElement = document.createElement("script");

}
}
function processResult(codeJ,messageJ,guessesJ) {
code = document.getElementById("code");
message = document.getElementById("message");

code.innerHTML = codeJ;
message.innerHTML = messageJ;
guesses.innerHTML = guessesJ;
if(codeJ == 0){
return;
}else if(codeJ == -1){
min = mid + 1;
}else if(codeJ == 1){

}
console.log(mid);
}
Check your variable-names. You are overwriting the function-patameters.
Something like
code.innerHTML = code;
message.innerHTML = message;
guesses.innerHTML = guesses;
just CAN'T work, you should see the problem yourself...
