I trying to iterate a delivery request for 3 times, but my code loops more than that, can someone please tell me why?
I tried so many examples from internet all of goes loop or crash in memory
I don't have any cvs file or anything that I'm trying to get the data from all set in body with some pre-request script that auto generate the values to the body.
call I want to repeat and I have 2 request in collection
In first token request I wrote couple of variables
pm.environment.set("repeat", 0);
pm.environment.set("count", 3);
token
and in second request I'm trying to iterate the call
while(pm.environment.get('count') >= pm.environment.get('repeat')){
postman.setNextRequest('delivery');
console.log("iteration " +pm.environment.get('repeat'))
pm.environment.get('repeat')+1;
}
delivery
Oh, classic off by one error, there are four iterations between 0 and 3 if you do >=.
Try >:
for(let i = pm.environment.get('count'); i > 0; i--){
...
}

I had this problem which Cooper helped me to solve it (thanks again for that), but now I'm struggling with a different one. The following script will count how many times a client code will appear on another Spreadsheet using as a second condition yesterday date.
function countSheets()
{
var vA = appSh();
var td = Utilities.formatDate(subDaysFromDate(new Date(),2), Session.getScriptTimeZone(), "dd/MM/yyyy");
var mbs=getAllSheets();
//var s='';
for (var i=2;i<vA.length;i++)
{
var d = Utilities.formatDate(new Date(vA[i][12]), Session.getScriptTimeZone(), "dd/MM/yyyy");
for(var key in mbs)
{
if(vA[i][0]==key && d==td)
{
mbs[key]+=1;
}
}
}
return mbs;
}
Then I have the below code which will search in the main spreadsheet (a table) a string and when was found will return row number, also will search for the date yesterday and return the column number. Based on these information I'll get the range where I need to paste the count result from the first script.
function runScript()
{
var ss=SpreadsheetApp.openById('ID');
var mbs=countSheets();
for(var key in mbs)
{
var sh=ss.getSheetByName(key);
var rg=sh.getDataRange();
var vA=rg.getValues();
for(var i=0;i<vA.length;i++)
{
if(vA[i][1]=='Total Number of Applications')
{
var nr=i;
break;//by terminating as soon as we find a match we should get improved performance. Which is something you cant do in a map.
}
}
if(typeof(nr)!='undefined')//If we don't find a match this is undefined
{
var today=subDaysFromDate(new Date(),2).setHours(0,0,0,0);
for(var i=0;i<vA[3].length;i++)
{
if(vA[3][i])//Some cells in this range have no contents
{
if(today.valueOf()==new Date(vA[3][i]).valueOf())
{
sh.getRange(nr+1,i+1,1,1).setValue(Number(mbs[key]));
}
}
}
}
}
return sh;
}
PROBLEM: I have 24 rows on the main Spreadsheet. So I will need to write the same script 24 times. As example, I need to count Total Number of Applications, Total Number of Calls, Number of Live Adverts and so on. If I do this it will exceed execution time since each script takes on average 25 seconds to run.
I did some researches on this website and internet and read about storing values and re-use them over and over. At the moment my script will have to go every time through the same file and count for each condition.
Q1: Is there any chance to create another array that contain all those strings from the second script?
Q2: How to use PropertiesService or anything else to store data and don't have to run over and over getValues() ? I've read Google Documentation but couldn't understand that much from it.
I hope it all make sense and can fix this problem.
My best regards,
Thank you!
My Approach to your Problem
You probably should write it for a couple of rows and then look at the two of them and see what is unique to each one. What is unique about each one is what you have to figure out how to store or access via an external function call.
The issue of time may require that you run these functions separately. I have a dialog which I use to load databases which does exactly that. It loads 800 lines and waits for 10 seconds then loads another 800 lines and wait for ten seconds and keeps doing that until there are no more lines. True it takes about 10 minutes to do this but I can be doing something else while it's working so I don't really care how long it takes. I do care about minimizing my impact to the Google Server though and so I don't run something like this just for fun.
By the way the 10 second delay is external to the gs function.
I am using a service to replace the words of an article with synonyms, the API of the service has a limit of 60 requests per minute. I have two functions, the first one get the article and split it into an Array, then calls the other to replace the words, I tried to do that by setting timeout to the second so it will be called first and then after 60 seconds, and then after 120 secs... so every minute I will call the service at most 60 times.
generateArticle : function(data){
Art.words = data.split(" ");
for(var j=0; j<Art.words.length/60; j+=1){
setTimeout(Art.generateSector(j*60),j*60000);
}
},
generateSector : function(position){
var count = 0;
for(var i=position; i<Art.words.length; i+=1){
if(Art.words[i].length > 3 && isNaN(Art.words[i]) && count < 60){
Art.findsimilarword(Art.words[i],i);
count++;
}
}
},
but what is happening is that the second function is called immediately, so in an article with 400 words the first 60 words will be replaced correctly but for the rest 340 words I am getting an error 429 (Too Many Requests) . Am I using the setTimeout with a wrong way? Can someone explain to me why this is happening?
This code:
setTimeout(Art.generateSector(j*60),j*60000);
calls Art.generateSector immediately, passing in j*60, and then takes its return value and passes it to setTimeout, exactly the way foo(bar()) calls bar and passes its return value into foo.
To schedule a call to the function, you pass in a function reference. In your case, you can probably use Function#bind:
setTimeout(Art.generateSector.bind(Art, j*60),j*60000);
Function#bind returns a new function that, when called, will call the original with the given value as this (in our case, Art) and any additional arguments you provide.
Function#bind is an ES5 feature. If you have to support really old JavaScript engines like the one in IE8, this feature can be "shimmed" ("polyfilled"). Search for "function bind shim" or "function bind polyfill" to find multiple options.
I have a program that we use at my work, which outputs its data in to XML files (several of them). I am trying to develop an HTA (yes an HTA, i'm sorry) to read these files and process their data. Unfortunately there are a number of XML files and I only need to read a few specific ones, so I am trying to write a generic "XML to array" function.
I got it to read the XML file and now I want to process the file into a 2d Array. However, since I am using a recursive function I seem to lose data. Here is the function:
NodesToArray = function (xmlDOC){
//Must redeclare "i" with each recursion, or it won't work correctly. ie: for(VAR i = 0...
for(var i = 0; i < xmlDOC.length ; i++){
//Just because it has a child still do the check.
if(xmlDOC[i].childNodes.length > 1){
//Recursively run the function.
var ReturnArray = NodesToArray(xmlDOC[i].childNodes);
//alert(ReturnArray + " " );
if(ReturnArray) return ReturnArray;
}else{
//Check to see if the node has a child node, if not and a child node is called, it will error out and stop
if(xmlDOC[i].hasChildNodes() == true){
return xmlDOC[i].firstChild.nodeValue;
}
}
}
}
Where I return the first child value I put an alert and was able to see all the data I wanted. Of course when I set it up I found it wasn't keeping the data. I've done a ton of reading and have been pounding my head against my desk and still can't come up with anything.
I've googled, searched this site, and consulted many forums, and can't find anything that would work for me. I post here reluctantly as I am at a dead end. Thanks for any help and I will provide any additional information as I can.
Just a note, but I would like to be able to do this without any libraries (specifically jQuery). The HTA doesn't seem to support a lot of newer Javascript. I'm not a professional coder by any means and learn by doing everything from scratch.
Not sure how to set the solution, but I found it
function NodesToArray(xmlDOC, returnArray){
for(var i = 0; i < xmlDOC.length ; i++){
if(xmlDOC[i].childNodes.length > 1){
returnArray[returnArray.length] = NodesToArray(xmlDOC[i].childNodes, []);
}else{
if(xmlDOC[i].hasChildNodes() == true){
returnArray[returnArray.length] = (xmlDOC[i].firstChild.nodeValue);
}
}
}
return returnArray;
}
getArray = NodesToArray(getXML.getElementsByTagName(tagName)[0].childNodes,[]);
Thanks for the help!
The general way of retrieving data recursively in the same container is to write two function:
First one is the one that you call and which returns the array
Second one is called by first function and does the recursion. To be able to put the data in the same array that function has to take it as parameter.
Here is some pseudo code
getData(node) {
_2D_array = new array[][];
getData(node, _2D_array, 0);
return array;
}
getData(node, _2D_array, depth) {
if(node) { // end of recursion ?
_2D_array[depth].add(...); // populate from node
getData(node.next, _2D_array, depth++);
}
}
Your program exits when the first element is processed because the function returns. A function can only return once. You need to move the return statements outside the loop so that the loop completes.
Ladies and gentlemen,
I'm stuck. I've been pondering this (and obviously have failed since I'm asking for your valuable assistance) in trying to get my code to work.
I need to come up with a simple (...I'm sorry, i'm new to this) code that prompt users to keep entering names using a loop. If the user does not enter 'q'(without quotes) and if the value entered is NOT null, then the value entered should be added to the array (in my case, names).
If the user enters 'q', the loop should stop, 'q' will not be entered in the array and the list of names should be printed (through the second function in my code).
Here's what I have so far... I can make the code work if I tell the loop to run i<5... it runs 5 times and then it stops. But it fails if i do i < names.length..it causes it say that length is null or not an object (on line 10). That's problem one. And for the life of me, I can't figure out how to add the logic that will run the loop until user enters q.
Please help!
Thank you.
function getNames(){
var names = new Array();
for(i=0;i<names.length;i++){ /*if i do i=0;i<5;i++, the code works; it doesn't with this*/
names[i] = prompt("Enter an item to add to the Name list (enter \'q\' to quit","");
}
printNames(names);
}
function printNames(names) {
for(x=0; x < names.length;x++){
document.write(names[x] + '<br />');
}
}
getNames();
printNames();
I am sure somewhere in your class/book it talks about while loops. So you want to use a while loop if you want them to keep entering without a limit.
while (myCondition===true) {
//do something
}
Now look at your for loop and figure out why it is failing.
for(i=0;i<names.length;i++)
Look at what it is doing:
i = 0
names.length = 0
Is 0 < 0?
Well to start with Problem 1:
Your names array begins with a length property of 0 and so your first for loop doesn't run because 0 is not less than 0.
Which leads to Problem 2:
Again since nothing was entered into your names array your second for loop again does nothing and doesn't execute document.write because the length property of your array is still 0.
How do I remove an items from a data bound array? My code follows.
for(var i = 0; i < listBox.selectedIndices.length; i++) {
var toRemove = listFiles.selectedIndices[i];
dataArray.splice(toRemove, 1);
}
Thanks in advance!
Edit Here is my swf. The Add Photos works except when you remove items.
http://www.3rdshooter.com/Content/Flash/PhotoUploader.html
Add 3 photos different.
Remove 2nd photo.
Add a different photo.
SWF adds the 2nd photo to the end.
Any ideas on why it would be doing this?
Edit 2 Here is my code
private function OnSelectFileRefList(e:Event):void
{
Alert.show('addstart:' + arrayQueue.length);
for each (var f:FileReference in fileRefList.fileList)
{
var lid:ListItemData = new ListItemData();
lid.fileRef = f;
arrayQueue[arrayQueue.length]=lid;
}
Alert.show('addcomplete:' + arrayQueue.length);
listFiles.executeBindings();
Alert.show(ListItemData(arrayQueue[arrayQueue.length-1]).fileRef.name);
PushStatus('Added ' + fileRefList.fileList.length.toString() + ' photo(s) to queue!');
fileRefList.fileList.length = 0;
buttonUpload.enabled = (arrayQueue.length > 0);
}
private function OnButtonRemoveClicked(e:Event):void
{
for(var i:Number = 0; i < listFiles.selectedIndices.length; i++) {
var toRemove:Number = listFiles.selectedIndices[i];
//Alert.show(toRemove.toString());
arrayQueue.splice(toRemove, 1);
}
listFiles.executeBindings();
Alert.show('removecomplete:' + arrayQueue.length);
PushStatus('Removed photos from queue.');
buttonRemove.enabled = (listFiles.selectedItems.length > 0);
buttonUpload.enabled = (arrayQueue.length > 0);
}
It would definitely be helpful to know two things:
Which version of ActionScript are you targeting?
Judging from the behavior of your application, the error isn't occurring when the user removes an item from the list of files to upload. Looks more like an issue with your logic when a user adds a new item to the list. Any chance you could post that code as well?
UPDATE:
Instead of: arrayQueue[arrayQueue.length]=lid
Try: arrayQueue.push(lid)
That will add a new item to the end of the array and push the item in to that spot.
UPDATE 2:
Ok, did a little more digging. Turns out that the fileList doesn't get cleared every time the dialog is opened (if you're not creating a new instance of the FileReferenceList each time the user selects new files). You need to call splice() on the fileList after you add each file to your Array.
Try something like this in your AddFile() method...
for(var j:int=0; j < fileRefList.fileList.length; j++)
{
arrayQueue.push(fileRefList.fileList[j]);
fileRefList.fileList.splice(j, 1);
}
That will keep the fileList up to date rather than holding on to previous selections.
I see one issue. The selected indices are no longer valid once you have spliced out the first element from the array. But that should only be a problem when removing multiple items at once.
I think we need to see more code about how you are handling the upload before we can figure out what is going on. It looks to me like you are holding a reference to the removed FileReference or something. The described problem is occurring when you upload a new file, not when you remove the selected one.
Do you mean to use listBox and listFiles to refer to the same thing?
I'm stepping out on a limb here, because I don't have a ton of experience with JavaScript, but I'd do this the same way that I'd do it in C, C++, or Java: By copying the remaining array elements down into their new locations.
Assuming that listFiles.selectedIndices is sorted (and its contents are valid indices for dataArray), the code would be something like the following:
(WARNING: untested code follows.)
// Don't bother copying any elements below the first selected element.
var writeIndex = listFiles.selectedIndices[0];
var readIndex = listFiles.selectedIndices[0] + 1;
var selectionIndex = 1;
while(writeIndex < (dataArray.length - listFiles.selectedIndices.length)) {
if (selectionIndex < listFiles.selectedIndices.length) {
// If the read pointer is currently at a selected element,
// then bump it up until it's past selected range.
while(selectionIndex < listFiles.selectedIndices.length &&
readIndex == listFiles.selectedIndices[selectionIndex]) {
selectionIndex++;
readIndex++;
}
}
dataArray[writeIndex++] = dataArray[readIndex++];
}
// Remove the tail of the dataArray
if (writeIndex < dataArray.length) {
dataArray.splice(writeIndex, dataArray.length - writeIndex);
}
EDIT 2009/04/04: Your Remove algorithm still suffers from the flaw that as you remove items in listFiles.selectedIndices, you break the correspondence between the indices in arrayQueue and those in listFiles.selectedIndices.
To see this, try adding 3 files, then doing "Select All" and then hit Remove. It will start by removing the 1st file in the list (index 0). Now what had been the 2nd and 3rd files in the list are at indices 0 and 1. The next value taken from listFiles.selectedIndices is 1 -- but now, what had been the 3rd file is at index 1. So the former File #3 gets spliced out of the array, leaving the former 2nd file un-removed and at index 0. (Using more files, you'll see that this implementation only removes every other file in the array.)
This is why my JavaScript code (above) uses a readIndex and a writeIndex to copy the entries in the array, skipping the readIndex over the indices that are to be deleted. This algorithm avoids the problem of losing correspondence between the array indices. (It does need to be coded carefully to guard against various edge conditions.) I tried some JavaScript code similar to what I wrote above; it worked for me.
I suspect that the problem in your original test case (removing the 2nd file, then adding another) is analogous. Since you've only shown part of your code, I can't tell whether the array indices and the data in listFiles.selectedIndices, arrayQueue, and fileRefList.fileList are always going to match up appropriately. (But I suspect that the problem is that they don't.)
BTW, even if you fix the problem with using splice() by adjusting the array index values appropriately, it's still an O(N2) algorithm in the general case. The array copy algorithm is O(N).
I'd really need to see the whole class to provide a difinitive answer, but I would write a method to handle removing multiple objects from the dataProvider and perhaps assigning a new array as the dataProvider for the list instead of toying with binding and using the same list for the duration. Like I said, this is probably inefficient, and would require a look at the context of the question, but that is what I would do 9unless you have a big need for binding in this circumstance)
/**
* Returns a new Array with the selected objects removed
*/
private function removeSelected(selectedItems:Array):Array
{
var returnArray:Array = []
for each(var object:Object in this.arrayQueue)
{
if( selectedItems.indexOf(object)==-1 )
returnArray.push( object )
}
return returnArray;
}
You might be interested in this blog entry about the fact that robust iterators are missing in the Java language.
The programming language, you mentioned Javascript, is not the issue, it's the concept of robust iterators that I wanted to point out (the paper actually is about C++ as the programming language).
The [research document]() about providing robust iterators for the ET++ C++ framework may still e helpful in solving your problem. I am sure the document can provide you with the necessary ideas how to approach your problem.
