I have string with values :
var string = 1-1, 1-2, 2-8, 2-10, 3-13, 3-14, 3-15,
now i want to combine them as follow:
var result = 1-1,2| 2-8,10| 3-13,14,15
How to achieve this in JQuery or Javascript.
var string = "1-1, 1-2, 2-8, 2-10, 3-13, 3-14, 3-15";
var result_array = [];
string.split(",").forEach(function (item) {
var first_number = item.trim().split("-")[0];
var second_number = item.trim().split("-")[1];
if (!result_array[first_number]) {
result_array[first_number] = [];
}
result_array[first_number].push(second_number);
});
var ordered_result = [];
result_array.forEach(function (content, index) {
ordered_result.push(index + "-" + content.join(","));
});
var result = ordered_result.join("| ");
console.log(result);

Using app scripts I'm trying to extract all the email addresses from email messages and put them in an array. From my console.log messages, I'm getting stuck because it looks like instead of an array I just get a string. i'm not too familiar with javascript. Any help would be great. I'm looking for an array of email address. The methods of message.get() return a string. I want to split out the email address and create a single, unified array.
var ui = SpreadsheetApp.getUi();
function onOpen(e){
ui.createMenu("Gmail Manager").addItem("Get Emails by Label", "getGmailEmails").addToUi();
}
function getGmailEmails(){
var label = GmailApp.getUserLabelByName("MyLabel");
var threads = label.getThreads();
var fullArray = [];
for(var i = threads.length - 1; i >=0; i--){
var messages = threads[i].getMessages();
for (var j = 0; j <messages.length; j++){
var message = messages[j];
if (message.isUnread()){
fullArray.push(extractDetails(message));
}
}
}
console.log("FullArray:"+fullArray);
for(var i=0; i<fullArray.length; i++){
console.log("printing array " + i + ": "+fullArray[i])
}
}
function extractDetails(message){
var dateTime = message.getDate();
var subjectText = message.getSubject();
var senderDetails = message.getFrom();
var ccEmails = message.getCc();
var replyEmail = message.getReplyTo();
var toEmail = message.getTo();
var emailArray = []
var senderArray = senderDetails.split(',');
var ccArray = ccEmails.split(',');
var replyArray = replyEmail.split(',');
var toArray = toEmail.split(',');
for (var i =0 ; i<toArray.length; i++){
console.log("toArray Loop"+ i + " : "+ toArray[i]);
emailArray.push([toArray[i]]);
}
for (var i =0 ; i<ccArray.length; i++){
console.log("ccArray Loop"+ i + " : "+ ccArray[i]);
emailArray.push([ccArray[i]]);
}
console.log("Email Array: "+ emailArray);
var activeSheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
activeSheet.appendRow([dateTime, senderDetails, subjectText, ccEmails,replyEmail,toEmail,emailArray]);
return emailArray;
}
I think the problem is just the console output. If you change console.log("Email Array: "+ emailArray); to console.log("Email Array: ", emailArray);, then it shows an array of arrays. You could simplify your extract method as follows:
function extractDetails(message) {
/* ... */
var senderDetails = message.getFrom();
var ccEmails = message.getCc();
var replyEmails = message.getReplyTo();
var toEmails = message.getTo();
let emailArray = [senderDetails, ccEmails, replyEmails, toEmails].reduce(
(array, string) => {
//remove names (like "Name <name#company.com>") and filter empty values
let emails = string
.split(/\s*,\s*/)
.map(e => e.replace(/.*?([^#<\s]+#[^#\s>]+).*?/g, "$1"))
.filter(Boolean);
if(emails.length > 0)
return array.concat(emails)
return array
}, []);
/* ... */
}
i try with Node Red to build an query to send multiple values to an influxDB from a loop with this code:
var inputArray = msg.payload;
var lenInputArray =inputArray.length;
var modbusStartRegister = 14000;
var sendString = "";
var msg93 ={};
for (i = 0; i < lenInputArray; i++) {
var actRegister = modbusStartRegister +i;
var actValue = inputArray[i];
if ( i >=1){
sendString = sendString + " ,"
}
sendString = sendString +"{register: " + actRegister +"," +"value: " + actValue +"}";
if ( i ==(lenInputArray-1)){
sendString = sendString + "]"
}
}
msg93.payload = sendString;
return msg93
But the insert in the influxDB is one line it looks at them interpreted as an complete string. How can I build or convert the string that the DB accept them as individual entry? Thanks for the help
This is because you are building a string, node an object.
You can build the array object on the fly like this:
var inputArray = msg.payload;
var lenInputArray =inputArray.length;
var modbusStartRegister = 14000;
var payload = [];
var msg93 ={};
for (i = 0; i < lenInputArray; i++) {
var temp = {};
temp.register = modbusStartRegister +i;
temp.value = inputArray[i];
payload.push(temp);
}
msg93.payload = payload;
return msg93
My script javascript like this :
<script>
var url = 'http://my-app.test/item';
var sessionBrand = 'honda';
var sessionModel = 'jazz';
var sessionCategory = 'velg';
var sessionKeyword = 'RS 175/60 R 15';
if(sessionBrand)
var brand = '?brand='+sessionBrand;
else
var brand = '';
if(sessionModel)
var model = '&model='+sessionModel;
else
var model = '';
if(sessionCategory)
var category = '&category='+sessionCategory;
else
var category = '';
if(sessionKeyword)
var keyword = '&keyword='+this.sessionKeyword;
else
var keyword = '';
var newUrl = url+brand+model+category+keyword;
console.log(newUrl);
</script>
The result of console.log like this :
http://my-app.test/item?brand=honda&model=jazz&category=velg&keyword=RS 175/60 R 15
var sessionBrand, sessionModel, sessionCategory and sessionKeyword is dynamic. It can change. It can be null or it can have value
I have a problem
For example the case like this :
var sessionBrand = '';
var sessionModel = '';
var sessionCategory = '';
var sessionKeyword = 'RS 175/60 R 15';
The url to be like this :
http://my-app.test/item&keyword=RS 175/60 R 15
Should the url like this :
http://my-app.test/item?keyword=RS 175/60 R 15
I'm still confused to make the condition
How can I solve this problem?
Just use the array for params and then join them with & separator. For example:
var url = 'http://my-app.test/item';
var sessionBrand = 'honda';
var sessionModel = 'jazz';
var sessionCategory = 'velg';
var sessionKeyword = 'RS 175/60 R 15';
var params = [];
if (sessionBrand) {
params.push('brand=' + sessionBrand);
}
if (sessionModel) {
params.push('model=' + sessionModel);
}
if(sessionCategory) {
params.push('category=' + sessionCategory);
}
if(sessionKeyword) {
params.push('category=' + sessionCategory);
}
var newUrl = url + '?' + params.join('&');
console.log(newUrl);
The problem with your code is that it is prefacing all query parameters with a & - except for the sessionBrand. What you need in a URL is for the first parameter to start with a ?, and all others with a &. As you saw, your code doesn't do this when there is no sessionBrand.
There are number of ways to fix this. Probably the neatest I can think of is to assemble the various parts as you are, but without any prefixes - then join them all together at the end. Like this (I just saw Viktor's solution, it's exactly the same idea, but neater because he rewrote more of your earlier code):
if(sessionBrand)
var brand = 'brand='+sessionBrand;
else
var brand = '';
if(sessionModel)
var model = 'model='+sessionModel;
else
var model = '';
if(sessionCategory)
var category = 'category='+sessionCategory;
else
var category = '';
if(sessionKeyword)
var keyword = 'keyword='+this.sessionKeyword;
else
var keyword = '';
var queryString = '?' + [sessionBrand, sessionModel, sessionCategory, sessionKeyword].filter(function(str) {
return str.length > 0;
}).join("&");
var newUrl = url+queryString;
I have a giving string/url like this
https://example.com/loadcontent?var1=100&var2=:somevar&var3=:morevariables
I need to loop thought each parameter in the url. If the value starts with : this indicated that it is a variable an I will need to change that value dynamically by looking at the corresponding meta attribute that matches that variable.
Here is my code in which loops over an array and sets the value of the parameters.
var baseURL = getBaseURL(url);
var params = getParams(url);
var newParams = $.each(params, function(index, param){
if( param.value.substring(0, 1) == ':'){
var myVar = param.value.substring(1);
param.value = $('meta[name=" + myVar + "']).attr('value');
}
});
var finalURL = baseURL + '?' + jQuery.param( newParams );
function getParams(url){
// This function should return an array of objects. Each object should have 2 properties "value" and "name". The "name" property should be the name of the parameter (ie. var1, var2, var3 .....) and the "value" attribute should contains the value of the parameter (ie. 100, :somevar, :morevariables)
}
function getBaseURL(url){
var cutoff = url.indexOf('?');
if( cutoff > -1){
return url.substring(0, cutoff - 1);
}
return url;
}
I need help converting the parameters of a giving URL to array of object. How can I do this in jQuery?
You dont need jQuery for this one.
function getParams(url) {
var queryString = url.substring(url.indexOf('?') + 1);
var paramsArr = queryString.split('&');
var params = [];
for (var i = 0, len = paramsArr.length; i < len; i++) {
var keyValuePair = paramsArr[i].split('=');
params.push({
name: keyValuePair[0],
value: keyValuePair[1]
});
}
return params;
}
Here is an example using map
var url = 'https://example.com/loadcontent?var1=100&var2=:somevar&var3=:morevariables&test';
function getParamArray(url) {
var queryString = url.substring(url.lastIndexOf("?") + 1);
return queryString.split('&').map(function(sParam) {
var param = sParam.split('=');
return {
name: param[0],
value: decodeURIComponent(param[1])
};
});
}
document.getElementById("output").innerHTML = JSON.stringify(getParamArray(url), null, 2);
<pre id="output"></pre>
With a regular expresion and JSON.parse:
var url = 'https://example.com/loadcontent?var1=100&var2=:somevar&var3=:morevariables';
url = url.replace(/^.*\?/,'');
url = url.replace(/(\w+)=?([\w:]*)/g,'{"name":"$1","value":"$2"}');
url = url.replace(/&/g,',');
var paramsObject = JSON.parse("["+url+"]");
/*
Returns:
Array [{"name":"var1","value":"100"},{"name":"var2","value":":somevar"},{"name":"var3","value":":morevariables"}];
*/
You don't even need JQuery for this.
<script type="text/javascript">
var paramStr = window.location.search;
var params = paramStr.substring(1, paramStr.length).split('&');
var paramList = [];
for (var index=0; index < params.length; index++) {
var param = params[index].split('=');
paramList.push({name: param[0], value: param[1]});
}
</script>
The result:
[Object]0: Object
name: "a"
value: "b"
...
var url=new URLSearchParams(window.location.search);
var params = [];
for(var value of url.keys())
{
params.push({
name: value,
value: url.get(value)
});
}
I have a script that uses AJAX/PHP/SQL to query data and pushes it into an array with a bunch of IF's statements. The changeData function is called every 6 seconds. The first query I return I have 6 arrays. The second time i send a request, my push array(IsVacant1) is double and went to 12. after a while, I have over 500 arrays going into my .each statement.
How do I 'clear' this every time I make a request so that I am not adding arrays? Any help is most appreciated.
function changeData() {
isPaused = true;
var mydata0 = null;
$.post('php/ProductionChange.php', {
'WC': cc
}, function(data) { // This is Where I use an AJAX call into a php file.
mydata0 = data; // This takes the array from the call and puts it into a variable
var pa = JSON.parse(mydata0); // This parses the data into arrays and elements
var temp = {};
var bayData = '';
if (pa != null) {
for (var i = 0; i <= pa.length - 1; i++) {
var job = pa[i][0];
var shipdate = pa[i][1];
var status = pa[i][2];
var name = pa[i][3];
var EnclLoc = pa[i][13];
var Enclsize = pa[i][14];
var backpan = pa[i][15];
var percentCom = pa[i][16];
var IsVisible = pa[i][17];
var png = pa[i][18];
var WorkC = pa[i][20];
baydata = 'bayData' + i + '';
temp = {
job, shipdate, name, EnclLoc, Enclsize, backpan, percentCom, IsVisible, png, WorkC, status
};
isVacant1.push({
baydata: temp
});
}
} else {
ii = 1;
//alert("There are no more job numbers in this bay location. Thank you. ");
}
$.each(isVacant1, function(key, value) {
var job = value.baydata.job;
var ship = value.baydata.shipdate;
var name = value.baydata.name;
var encl = value.baydata.EnclLoc;
var EnclSize = value.baydata.EnclLoc;
var percentCom = value.baydata.percentCom;
var backpan = value.baydata.backpan;
var PngLogo = value.baydata.png;
var IsVisible = value.baydata.IsVisible;
var WorkC = value.baydata.WorkC;
var status = value.baydata.status;
var p = WorkC;
WorkC = (WorkC < 10) ? ("0" + WorkC) : WorkC;
//// remember if the encl location matches the workcell cell then do stuff based on that....... hint encl image not hiding becase of duplicate 17s
if (((encl == p) || (backpan == p)) && job != 123) {
$('#WC' + p).show();
document.getElementById("bayData" + p).innerHTML = name + ' ' + ship; // Work Cell Name and Ship Date
document.getElementById("bayData" + p + "a").innerHTML = job; // Work cell Job Number
document.getElementById("percentCom" + p).innerHTML = percentCom + '%'; // Work Cell Percent Complete
} else {
$('#WC' + p).hide();
From your question it looks like you want to clear the isVacant1 array.
In your ajax callback just put isVacant1 = []; as the first line. Like this
function(data) { // This is Where I use an AJAX call into a php file.
isVacant1 = [];
mydata0 = data; // This takes the array from the call and puts it into a variable
var pa = JSON.parse(mydata0); // This parses the data into arrays and elements
var temp = {};
var bayData = '';
..................
From your code it's not clear how you are declaring/initializing isVacant1 so i have suggested isVacant1 = [] otherwise you can also use isVacant1.length = 0.
