How do I iterate nested API response in AJAX?

I'm trying to iterate a nested API response and display them inside a html. I managed to do single image because the response only have single value.
**API response **
{"result":{"totalResults":5861511,"products":[{"productTitle":"S-XL Plus Size Tunic Autumn <font><b>Women</b></font> Dresses Casual Cartoon Print Christmas Dress Casual Loose Long Sleeve Party Dress Vestidos","originalPrice":"US $7.98","imageUrl":"https://ae01.alicdn.com/kf/H3ba2899c892d4a88a5f704453c39942ae/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg","productUrl":"https://www.aliexpress.com/item/S-XL-Plus-Size-Tunic-Autumn-Women-Dresses-Casual-Cartoon-Print-Christmas-Dress-Casual-Loose-Long/4000353066650.html","allImageUrls":"https://ae01.alicdn.com/kf/H3ba2899c892d4a88a5f704453c39942ae/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg,https://ae01.alicdn.com/kf/H218b19ee8bfc4f6ebe74b4297ca8395f5/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg,https://ae01.alicdn.com/kf/H14b48746d6eb4d5788a7a9f6ce37195c7/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg,https://ae01.alicdn.com/kf/Hb4b1f8b6223d4e7c88208751bfa681886/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg,https://ae01.alicdn.com/kf/Hcfd17f95ac85470d9550d13f3683adc1I/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg}]},"errorCode":20010000,"currentPageNum":0,"totalPageNum":0}

How do you create a loop for $output from allImageUrls ?

You need to split the allImageUrls and then run them in a loop as follows:
var result ={
"result": {
"totalResults": 5861511,
"products": [
{
"productTitle": "S-XL Plus Size Tunic Autumn <font><b>Women</b></font> Dresses Casual Cartoon Print Christmas Dress Casual Loose Long Sleeve Party Dress Vestidos",
"originalPrice": "US $7.98",
"imageUrl": "https://ae01.alicdn.com/kf/H3ba2899c892d4a88a5f704453c39942ae/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg",
"productUrl": "https://www.aliexpress.com/item/S-XL-Plus-Size-Tunic-Autumn-Women-Dresses-Casual-Cartoon-Print-Christmas-Dress-Casual-Loose-Long/4000353066650.html",
"allImageUrls": "https://ae01.alicdn.com/kf/H3ba2899c892d4a88a5f704453c39942ae/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg,https://ae01.alicdn.com/kf/H218b19ee8bfc4f6ebe74b4297ca8395f5/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg,https://ae01.alicdn.com/kf/H14b48746d6eb4d5788a7a9f6ce37195c7/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg,https://ae01.alicdn.com/kf/Hb4b1f8b6223d4e7c88208751bfa681886/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg,https://ae01.alicdn.com/kf/Hcfd17f95ac85470d9550d13f3683adc1I/S-XL-Plus-Size-Tunic-Autumn-font-b-Women-b-font-Dresses-Casual-Cartoon-Print-Christmas.jpg"
}
]
},
"errorCode": 20010000,
"currentPageNum": 0,
"totalPageNum": 0
}
var allImagesList = result.result.products[0].allImageUrls.split(',');
allImagesList.forEach((imageUrl)=>{
console.log(imageUrl);
})
And your code will look like something as below:
$(function (){
var $orders = $('#orders');
var $productimage = $('#productimage');
var $output = $('#output');
$.ajax({
type: 'GET',
url: 'http://gw.api.alibaba.com/openapi/param2/2/portals.open/api.listPromotionProduct/9420?fields=productUrl,allImageUrls,imageUrl,originalPrice,productTitle&keywords=women',
success: function(orders){
$.each(orders, function(i, order){
$orders.append('' + order.products[0].productTitle + '');
$output.append(order.products[0].allImageUrls[1]);
var allImagesList = order.products[0].allImageUrls.split(',');
allImagesList.forEach((imageUrl)=>{
$productimage.append('<img class="pic-1" src="' + imageUrl + '">'); // single image
})
});
}
});
});

$.each(orders, function(i, order) {
$orders.append('' + order.products[0].productTitle + '');
//------------------------Start
var allImageUrlsArray = []; // Create array;
//split with comma, assign to varaible and loop it.
allImageUrlsArray = order.products[0].allImageUrls.split(',');
for (var i = 0; i < allImageUrlsArray.length; i++) {
$output.append(allImageUrlsArray[i]);
}
//---------------------------End
});

You did some mistakes in iterate JSON Object, and allImageUrls contain multiple images with comma(,) so you should convert this into array. Let's check the below example
LN: 21 you can loop the allImageUrls
for([k, v] of Object.entries(value.allImageUrls)){
console.log(k, v);
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="orders"></div>
<script>
$(function() {
var $orders = $('#orders');
var $productimage = $('#productimage');
var $output = $('#output');
$.ajax({
type: 'GET',
url: 'https://gw.api.alibaba.com/openapi/param2/2/portals.open/api.listPromotionProduct/9420?fields=productUrl,allImageUrls,imageUrl,originalPrice,productTitle&keywords=women',
success: function(item) {
let orders = item.result.products;
orders = orders.map(product => {
product.allImageUrls = product.allImageUrls.split(',');
return product;
});
var con = '';
for ([key, value] of Object.entries(orders)) {
con += "<li><a href='" + value.productUrl + "'><img style='width: 30px;' src='" + value.allImageUrls[0] + "'/>" + value.productTitle + "</a></li>";
// Loop all images
for ([k, v] of Object.entries(value.allImageUrls)) {
console.log(k, v);
}
}
$orders.append("<ul>" + con + "</ul>");
}
});
});
</script>

$(function() {
var $orders = $('#orders');
var $productimage = $('#productimage');
var $output = $('#output');
$.ajax({
type: 'GET',
url: 'http://gw.api.alibaba.com/openapi/param2/2/portals.open/api.listPromotionProduct/9420?fields=productUrl,allImageUrls,imageUrl,originalPrice,productTitle&keywords=women',
success: function(orders) {
$.each(orders.result.products, function(i, order) {
console.log(order)
$div = $('<div id = "' + "order_" + i + '"></div>');
$imageDiv = $('<div id = "' + "image_" + i + '"></div>');
// = $('#order_' + i);
console.log($div)
$div.append('' + order.productTitle + '');
//;
var array = order.allImageUrls.split(',');
for (var j = 0; j < array.length; j++) {
//$output.append(order.allImageUrls[j]);
$imageDiv.append('<img style="width:50px;height:50px" class="pic-1" src="' + array[j] + '">'); // single image
}
$div.append($imageDiv);
$orders.append($div);
});
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="output">
<div id="orders">

Hope this helps. :)

Leaflet JS with loop in JavaScript

I'm trying to create a loop to add multiple markers to an Leaflet map. One marker works, but when I try to do this with a loop, the markers don't work. I receive the data for the markers from a google spreadsheet.
$(document).ready(function() {
console.log("ready!");
// ID of the Google Spreadsheet
var spreadsheetID = "spreadsheetID";
// Make sure it is public or set to Anyone with link can view
var url = "https://spreadsheets.google.com/feeds/list/" + spreadsheetID + "/1/public/values?alt=json";
$.getJSON(url, function(data) {
var entry = data.feed.entry;
var amount = entry.lenght;
var i;
for (i = 0; i <= amount; i++) {
var lat = data.feed.entry[i]['gsx$lat']['$t'];
var lon = data.feed.entry[i]['gsx$lon']['$t'];
var name = data.feed.entry[i]['gsx$name']['$t'];
var to = data.feed.entry[i]['gsx$to']['$t'];
var time = data.feed.entry[i]['gsx$time']['$t'];
var tel = data.feed.entry[i]['gsx$tel']['$t'];
var marker = L.marker([lon, lat]).addTo(mymap);
marker.bindPopup('<b>Name:</b> ' + name + '<br><b>To:</b> ' + to + '<br><b>Time:</b> ' + time + '<br><b> Tel:</b> ' + tel);
}
})
});

Your code with typo and LatLng problem fixed:
$(document).ready(function() {
console.log("ready!");
// ID of the Google Spreadsheet
var spreadsheetID = "spreadsheetID";
// Make sure it is public or set to Anyone with link can view
var url = "https://spreadsheets.google.com/feeds/list/" + spreadsheetID + "/1/public/values?alt=json";
$.getJSON(url, function(data) {
var entry = data.feed.entry;
var amount = entry.length;
var i;
for (i = 0; i < amount; i++) {
var lat = data.feed.entry[i]['gsx$lat']['$t'];
var lon = data.feed.entry[i]['gsx$lon']['$t'];
var name = data.feed.entry[i]['gsx$name']['$t'];
var to = data.feed.entry[i]['gsx$to']['$t'];
var time = data.feed.entry[i]['gsx$time']['$t'];
var tel = data.feed.entry[i]['gsx$tel']['$t'];
var marker = L.marker([lat, lon]).addTo(mymap);
marker.bindPopup('<b>Name:</b> ' + name + '<br><b>To:</b> ' + to + '<br><b>Time:</b> ' + time + '<br><b> Tel:</b> ' + tel);
}
})
});

Leaflet geojson search and zoom

Well I'm trying to combine 2 examples to search from my geojson file, and when selected it will zoom that property.
Search (search in GeoJSON one) http://labs.easyblog.it/maps/leaflet-search/examples/
Zoom part from here (without the dropdown) http://projects.bryanmcbride.com/leaflet/select_zoom.html
Basically the first one just with zoom from second. I have been able to get them working, but separately.
Codes (1.)
var featuresLayer = new L.GeoJSON(piirid, {
style: function(f) {
return {color: f.properties.color };
}
});
map.addLayer(featuresLayer);
var searchControl = new L.Control.Search({layer: featuresLayer, propertyName: 'L_AADRESS', circleLocation:false});
searchControl.on('search_locationfound', function(e) {
e.layer.setStyle({fillColor: '#3f0', color: '#0f0'});
}).on('search_collapsed', function(e) {
featuresLayer.eachLayer(function(layer) { //restore feature color
featuresLayer.resetStyle(layer);
});
});
map.addControl( searchControl ); //inizialize search control
Code 2.
// Loop through the geojson features and extract bbox and name, then add the options to the "zoom" select (no jQuery)
/*var select = document.getElementById("zoom");
select.options[select.options.length] = new Option('Select a State', 'Select a State');
for (each in geojson._layers) {
var bbox = geojson._layers[each].getBounds()._southWest.lat + "," + geojson._layers[each].getBounds()._southWest.lng + "," + geojson._layers[each].getBounds()._northEast.lat + "," + geojson._layers[each].getBounds()._northEast.lng;
select.options[select.options.length] = new Option(geojson._layers[each].feature.properties.name, bbox);
}*/
// Loop through the geojson features and extract bbox and name, then add the options to the "zoom" select and build autocomplete(using jquery)
var options = '<option value="Select a State">Select a State</option>';
var states = [];
for (each in geojson._layers) {
var L_AADRESS = geojson._layers[each].feature.properties.L_AADRESS;
var swLat = geojson._layers[each].getBounds()._southWest.lat;
var swLng = geojson._layers[each].getBounds()._southWest.lng;
var neLat = geojson._layers[each].getBounds()._northEast.lat;
var neLng = geojson._layers[each].getBounds()._northEast.lng;
var bbox = swLat + "," + swLng + "," + neLat + "," + neLng;
// Populate states array and build autocomplete
states.push({label: L_AADRESS, value: L_AADRESS, swlat: swLat, swlng: swLng, nelat: neLat, nelng: neLng});
$( "#search" ).autocomplete({
source: states,
minLength: 3,
select: function( event, ui ) {
map.fitBounds([[ui.item.swlat, ui.item.swlng],[ui.item.nelat, ui.item.nelng]]);
}
});
// Add states & bbox values to zoom select options
options += '<option value="' + bbox + '">' + geojson._layers[each].feature.properties.L_AADRESS + '</option>';
}

If I understand your question correctly you just have to add:
map.fitBounds(e.layer.getBounds());
to the search_locationfound event function.
This will set the maximum zoom level that you can still see the whole layer.
So the search_locationfound event function from your first example would be:
searchControl.on('search_locationfound', function(e) {
map.fitBounds(e.layer.getBounds());
e.layer.setStyle({fillColor: '#3f0', color: '#0f0'});
});

How to populate new html pages with xml data in jQuery

I have an RSS reader that fetches events with ajax. I want the user to be able to click the link of the event and have it transition to a new page with the details. Here is an example I found: http://jsfiddle.net/hellosze/t22QP/ I am have trouble understanding what is happening since I am rather new to jQuery so I was hoping someone code direct me as to what is happening. Thanks!
Here is how I extract the xml data and display it to a main page:
$.ajax({
type: 'GET',
url: 'categoryURL',
dataType: 'xml',
success: function (xml) {
var data = [];
$(xml).find("item:lt(40)").each(function () {
var dateText = $(this).find("Date").text().toString();
var eventDate = moment(dateText,"YYYY-MM-DD");
var title = $(this).find("title").text();
var region = dateText.substr(8).toUpperCase();
if (region.length < 3) { region = "ALL"; }
var description = $(this).find("description").text();
var dateDisplay = description.substr(0, description.indexOf(",")+6); //Parsed DATE from description
if (dateDisplay.length > 35) { dateDisplay = "See event for details"; }
//var locationdisplay = description.substr(description.indexOf(",")+6,4); //Parsed the location from description
var category = $(this).find("category").text();
var linkUrl = $(this).find("link").text();
var displayTitle = "<a href='" + linkUrl + "' target='_blank'>" + title + "</a>"
var item = {title: displayTitle, DateDecription: dateDisplay, Date: new Date(eventDate), Region: region,}
data.push(item);
// $('#feedContainer').append('<h3>'+displaytitle+'</h3><p>'+"Event Date: "+descriptdisplay+'</p><p>'+"Location: "+region+'</p');
}); //END .each()
data.sort(function (a, b) {
a = new Date(a.Date);
b = new Date(b.Date);
return a>b ? -1 : a<b ? 1 : 0;
});
$.each(data, function (index, item) {
$('#feedContainer').append('<h3>' + item.title + '</h3><p>' + "Event Date: " + item.DateDecription + '</p><p>' + "Location: " + item.Region + '</p');
});
} //END success fn
});
});

Force Google InfoWindow To Redraw Itself or Refresh its content

I have included the sample code above. Please pay special attention to my click event handler. As always, as suggestions on how best to remedy this would be greatly appreciated.
Thanks in advance,

jQuery AJAX methods are asynchronous. That means:
obj.success(function (data) {
ecoli_rows = data['rows'];
}); // end sucess
Returns immediately but the callback function doesn't run until the ajax request completes.
This means that:
infoWindow.setContent(this.getHeader() + '' +
this.getEcoliData() + '' + this.getAlgaeData());
infoWindow.open(map, this); //ajax callback hasn't fired here
opens the info window with the content BEFORE the ajax request completes.
To correct, you might do something like this:
In marker.getEcoliData:
obj = getEcoliData(this.beach_id);
return obj;
// move processing below this point to new method
And in the click event handler:
google.maps.event.addListener(marker, 'click', function () {
var ajaxObj = this.getEcoliData();
var marker = this;
ajaxObj.done(function() {
infoWindow.setContent(marker.getHeader() + '' +
marker.afterGetEcoliData() + '' +
this.getAlgaeData());
infoWindow.open(map, this);
$(".tabs").tabs({ selected: 0 });
});
This is not a complete solution since you have two asynchronous calls happening. You could either chain them, or set some kind of counter to make sure that the callback only executes when both have completed.
An even better approach would be to immediately open the infowindow with some kind of information to tell the user that data is being loaded. Then after the requests complete, you simply update the infowindow content again (with a handle to the content element) to show the returned data.

Thanks for the help with this. I managed to get this to work as expected. As it turned out I had to restructure the marker class so that two ajax requests weren't be returned an additional time.
