jQuery and XML, find object that contains children with multiple specific values - javascript

For a project I have data stored in XML like this:
<xml>
<sprites>
<sprite>
<name>Tile1</name>
<lat>1</lat>
<lng>2</lng>
</sprite>
<sprite>
<name>Tile2</name>
<lat>3</lat>
<lng>4</lng>
</sprite>
</sprites>
<xml>
Through jQuery I want to get a tile object that matches two child values, the lat and lng values.
I found this post which was of great help, but sadly it only has an example of how to search for one matching value. Here's the code I have up to now:
// xml stored in 'xml' var
var findLat = 3;
var findLng = 4;
var mapSprites = $(xml).find("sprites");
var getSprite = $(mapSprites).find("sprite").filter(
function() {
return $(this).find('lat').text() == findLat;
},
function() {
return $(this).find('lng').text() == findLng;
}
);
Sadly getSprite is undefined, as I'm guessing you can't use the filter function as I've tried to use it? The example I linked to has one function as filter and seems to work, but comma separating doesn't seem to work as an AND, which is what I need.
The goal is to be able to give the function a lat and lng value and me being able to extract the <name> value.
Would be thankful for a push in the right direction, I'm pretty new to XML and parsing it through jQuery.

filter does not take multiple arguments. So combine it into one using "and".
var findLat = 3;
var findLng = 4;
var mapSprites = $(xml).find("sprites");
var getSprite = mapSprites.find("sprite").filter(
function() {
const node = $(this);
return Number(node.find('lat').text()) === findLat &&
Number(node.find('lng').text()) === findLng;
}
);

Google Script: Retrieving Default Values for Filter

I would like to create a filter for a column in a spreadsheet, then retrieve the list of default criteria values created for the filter. I believe that my code returns a Filter object without any values for it.
function TestFilter(){
var spreadsheet = SpreadsheetApp.getActive();
var sheet = spreadsheet.getActiveSheet();
sheet.getRange(1, 2, sheet.getMaxRows(), 1).createFilter();
var filter = sheet.getFilter();
var output = filter.getColumnFilterCriteria(2).getCriteriaValues();
return output;
}
You can use the following functions for this:
getHiddenValues()
Returns the values to hide.
getVisibleValues()
Returns the values to show.
In case your filter is set to hide all of the possible values, you will obtain what you desire by using the function getHiddenValues().
However, this will not be possible if your filter is only hiding a subset of your values. For that case, you could use a Google Apps Script function such as the following below to obtain the distinct values:
function getDistinctValues(range) {
var values = range.getValues();
var unique = {};
for (var i=0; i<values.length; i++) {
for (var j=0; j<values[i].length; j++) {
var key = values[i][j];
if (key !== null && key !== undefined && key !== '')
unique[key] = true;
}
}
return Object.keys(unique);
}
The usage of it would be, in case you were attempting to obtain the distinct values on your A column:
var distinctValues = getDistinctValues(sheet.getRange("A2:A"));
Note that this function will return the values as Strings. In case you want to obtain the actual numeric value instead of a String, you can parse the values simply by using the following code:
var distinctValues = getDistinctValues(sheet.getRange("A2:A")).map(parseFloat);
I believe there is a bug with 2 out of 3 of these functions, by using something like this:
var filter = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("sheetName").getFilter();
var criteriaValues = filter.getColumnFilterCriteria(9).getCriteriaValues();
Logger.log("criteria Values length " + criteriaValues.length);
Logger.log(criteriaValues);
var visibleValues = filter.getColumnFilterCriteria(9).getVisibleValues();
Logger.log("visible Values length " + visibleValues.length);
Logger.log(visibleValues);
var hiddenValues = filter.getColumnFilterCriteria(9).getHiddenValues();
Logger.log("hidden Values length " + hiddenValues.length);
Logger.log(hiddenValues);
and setting a filter on column I (9th from the left) regardless of how many or which values I filter by, I only ever see the values that I've hidden from the column, the criteriaValues and visibleValues arrays are always empty, while hiddenValues always shows correctly the values that are filtered out.
If someone could double check this and confirm it would be great, otherwise, maybe I'm just doing something really silly, in which case please let me know as well :).

excel javascript API array handling

I'm working on an add-in for excel 2016 using the javascript API. I can successfully get the range into an array and get the values to show in console.log. I've also been able to get the values into a JSON array using JSON.stringify();
I need to manipulate the array to remove the empty values ("").
Can this be accomplished by using regular javascript array methods?
I'm thinking I can display the results back into a different worksheet using a similar approach like i did with var shWk
Here are some snippets of what I'm trying to do:
(function () {
"use strict";
// The initialize function must be run each time a new page is loaded
Office.initialize = function (reason) {
$(document).ready(function () {
app.initialize();
//document.getElementById("date").innerHTML = Date("MAR 30 2017");
$('#deleteTab').click(deleteTab);
$('#preview').click(preview);
$('#publish').click(publish);
});
};
function preview() {
Excel.run(function(ctx) {
//getting the colname from a date range in B2
var colName = ctx.workbook.worksheets.getItem('preview').getRange("B2");
colName.load('values');
return ctx.sync().then(function() {
//converting colname value to string for column name
var wkN = (colName.values).toString();
// displaying on the task pane
document.getElementById("tst").innerText = wkN;
// testing to confirm i got the correct colname
var shWk = ctx.workbook.worksheets.getItem('preview').getRange("B3");
shWk.values = colName.values;
//building the column connection by setting the table name located on a different worksheet
var tblName = 'PILOT_ZMRP1';
var tblWK = ctx.workbook.tables.getItem(tblName).columns.getItem(wkN);
//loading up tblWK
tblWK.load('values');
return ctx.sync().then(function(){
//this is where my question is:
var arry = tblWK.values;
for (var i=0; i < tblWK.length; i++){
if (tblWK.values !== ""){
arry.values[i][0]) = tblWK.values[i][0]
};
};
console.log(arry.length); //returns 185
console.log (arry.values);//returns undefined
tblWK.values = arry;
var tblWeek = tblWK.values;
console.log(tblWeek.length);//returns 185
console.log(tblWK.values);//returns [object Array] [Array[1],Array[2]
})
});
}).catch(function (error) {
console.log(error);
console.log("debug info: " + JSON.stringify(error.debugInfo));
});
}
What am I missing? Can you point me to some resources for javascript array handling in the specific context of office.js?
I want to thank everyone for the time spent looking at this question. This is my second question ever posted on Stack Overflow. I see that the question was not written as clear as it could've been. What i was trying to achieve was filtering out the values in a 1D array that had "". The data populating the array was from a column in a separate worksheet that had empty values (hence the "") and numeric values in it. the code below resolved my issue.
//using .filter()
var itm = tblWK.values;
function filt(itm){
return itm != "";
}
var arry = [];
var sht = [];
var j=0;
var s=0;
arry.values = tblWK.values.filter(filt);
//then to build the display range to show the values:
for (var i=0; i < itm.length-1; i++) {
if (tblWK.values[i][0]){
var arry; //tblWK.values.splice(i,0); -splice did not work, maybe my syntax was wrong?
console.log("this printed: "+tblWK.values[i][0]);
var cl = ('D'+i); //building the range for display
j++; //increasing the range
s=1;//setting the beignning range
var cll = cl.toString();//getRange() must be a string
console.log(cll);//testing the output
}
}
//using the variable from the for loop
var cl = ('D'+s+':D'+j);
var cll = cl.toString();
console.log(cll);//testing the build string
sht = ctx.workbook.worksheets.getItem('Preview').getRange(cll);
sht.values = arry.values; //displays on the preview tab
console.log (arry.values); //testing the output
The question was probably easier said by asking what vanilla javascript functions does office.js support. I found a lot help reading Building Office Add-ins using Office.js by Micheal Zlatkovsky and by reading the MDN documentation as well as the suggested answer posted here.
Regards,
J
I'm not sure what this check is trying to achieve: tblWK.values !== "". .values is a 2D array and won't ever be "".
For Excel, the value "" means that the cell is empty. In other words, if you want to clear a cell, you assign to "". null value assignment results in no-op.
You can just fetch the values form the array that contains null by using for each and can can push the null values into another array.

Combining two object in javascript and convert to String

I am hoping I am missing something obvious here, but I have tried for the past half day to set two variables to combine in a certain format in Javascript I can do it as a string, however I need it in a different format.
If I select on option from the check boxes {"GILLS":"7"} works fine however if two options are selected query1 should look like [{"GILLS":"1"},{"GILLS":"7"}]. I cannot use += to the variable as this kicks out an unexpected token error.
var Query1 = '';
var Query3 = '';
if ($('input[name=checkbox2a]:checked').length > 0) {
var Query3 = {"GILLS":"7"};
}
if ($('input[name=checkbox2b]:checked').length > 0) {
var Query3 = {"GILLS":"1"};
}
Try
var Query1 = [];
and in your function use
Query1.push({"GILLS":"1"})
So the change will be like below
var Query1 = [];
var Query3 = [];
if ($('input[name=checkbox2a]:checked').length > 0) {
Query3.push({"GILLS":"7"});
}
if ($('input[name=checkbox2b]:checked').length > 0) {
Query3.push({"GILLS":"1"});
}
then you can use join will give you string
Query3.join(", ")
Make an array out of Query3, if you still want a string at the end, use .join("").
var Query1 = '';
var Query3 = [];
if ($('input[name=checkbox2a]:checked').length > 0) {
Query3.push({"GILLS":"7"});
}
if ($('input[name=checkbox2b]:checked').length > 0) {
Query3.push({"GILLS":"1"});
}
Query3 = Query3.join(""); // back to string, if you so like
You're causing pain for yourself if you take the approach that sometimes the variable is of type Object ({"GILLS": "1" }) and sometimes it is of type List ([{"GILLS":"1"},{"GILLS":"7"}]).
Since it sometimes needs to be a list, make sure it's always a list. Even though sometimes it's a list of length 1. Then when you are reading that value, you never need conditional logic to deal with two potential types.
So, it's always a List:
var query3 = [];
... and then it's easy to manipulate:
if(...) {
query3.push( { "GILLS": "7" } );
}
if(...) {
query3.push( { "GILLS": "1" } );
}
At first, you are declaring same variable in a different scope. Don't do this unless uou know what you are doing. In other words use var keyword only once for a variable in a "space" when you are using this particular variable.
An advantage/disadvantage (chose one ;)) of javascript is that there is no type control. If You type var Query3 = ''; and then Query3 = {"GILLS":"7"}; interpreter will execute this without any complaints beside that there is high probability, that this is not exactly what you want to do ;). In this case it makes variable Query3 an empty string and then makes it an object.
In Your case, You want to have in result an array of objects. At first declare var Query3=[]; and then use a push method on it (Query3.push({});) to add elements.

Google Script to see if text contains a value

I have a google form that when the user submits it will trigger my function to run which is creating a summary of what they submitted as a Google Doc. I know it can automatically send an email but I need it formatted in a way that my user can edit it later.
There are some check boxes on the form -- but the getResponse() is only populated with the items checked and I need it to show all possible choices. Then I will indicate somehow what was checked.
I can't find a way to see if a text contains a value.
Like in Java with a String, I could do either .contains("9th") or .indexOf("9th") >=0 and then I would know that the String contains 9th. How can I do this with google scripts? Looked all through documentation and I feel like it must be the easiest thing ever.
var grade = itemResponse.getResponse();
Need to see if grade contains 9th.
Google Apps Script is javascript, you can use all the string methods...
var grade = itemResponse.getResponse();
if(grade.indexOf("9th")>-1){do something }
You can find doc on many sites, this one for example.
Update 2020:
You can now use Modern ECMAScript syntax thanks to V8 Runtime.
You can use includes():
var grade = itemResponse.getResponse();
if(grade.includes("9th")){do something}
I had to add a .toString to the item in the values array. Without it, it would only match if the entire cell body matched the searchTerm.
function foo() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var s = ss.getSheetByName('spreadsheet-name');
var r = s.getRange('A:A');
var v = r.getValues();
var searchTerm = 'needle';
for(var i=v.length-1;i>=0;i--) {
if(v[0,i].toString().indexOf(searchTerm) > -1) {
// do something
}
}
};
I used the Google Apps Script method indexOf() and its results were wrong. So I wrote the small function Myindexof(), instead of indexOf:
function Myindexof(s,text)
{
var lengths = s.length;
var lengtht = text.length;
for (var i = 0;i < lengths - lengtht + 1;i++)
{
if (s.substring(i,lengtht + i) == text)
return i;
}
return -1;
}
var s = 'Hello!';
var text = 'llo';
if (Myindexof(s,text) > -1)
Logger.log('yes');
else
Logger.log('no');

Get Query String with Dojo

Users will be hitting up against a URL that contains a query string called inquirytype. For a number of reasons, I need to read in this query string with javascript (Dojo) and save its value to a variable. I've done a fair amount of research trying to find how to do this, and I've discovered a few possibilities, but none of them seem to actually read in a query string that isn't hard-coded somewhere in the script.
You can access parameters from the url using location.search without Dojo Can a javascript attribute value be determined by a manual url parameter?
function getUrlParams() {
var paramMap = {};
if (location.search.length == 0) {
return paramMap;
}
var parts = location.search.substring(1).split("&");
for (var i = 0; i < parts.length; i ++) {
var component = parts[i].split("=");
paramMap [decodeURIComponent(component[0])] = decodeURIComponent(component[1]);
}
return paramMap;
}
Then you could do the following to extract id from the url /hello.php?id=5&name=value
var params = getUrlParams();
var id = params['id']; // or params.id
Dojo provides http://dojotoolkit.org/reference-guide/dojo/queryToObject.html which is a bit smarter than my simple implementation and creates arrays out of duplicated keys.
var uri = "http://some.server.org/somecontext/?foo=bar&foo=bar2&bit=byte";
var query = uri.substring(uri.indexOf("?") + 1, uri.length);
var queryObject = dojo.queryToObject(query);
//The structure of queryObject will be:
// {
// foo: ["bar", "bar2],
// bit: "byte"
// }
In new dojo it's accessed with io-query:
require([
"dojo/io-query",
], function (ioQuery) {
GET = ioQuery.queryToObject(decodeURIComponent(dojo.doc.location.search.slice(1)));
console.log(GET.id);
});
Since dojo 0.9, there is a better option, queryToObject.
dojo.queryToObject(query)
See this similar question with what I think is a cleaner answer.
