    <p>I'm having problems trying to pass data to a function from within a each loop. I've roughly pasted my code below. Basically functionA gets JSON data, passes the response to functionB. I want to then pass each response item to functionC so they can be added to an array to plot markers using google maps. Any help would be appreciated. Thanks</p> <pre><code>if(app == undefined) var app = {}; app.Application = function() { this.functionA = function(){ var self = this; var urlHash = location.hash; accessToken = urlHash.split('=')[1]; if (!accessToken) { return false; } else { $.getJSON(instaAPIuri+"users/" + id + "/media/recent?access_token=" + accessToken + "&amp;callback=?", self.functionB); }; }; this.functionB = function(response){ var self = this; //Error codes if (response.meta.code == 400) { alert(response.meta.error_message); } //Create picture elements with basic information and image $.each(response.data, function (i, item) { //If item.location == null, while trying to get geolocation = error if (item.location != null) { functionC( item.location.latitude, item.location.longitude, item.images.thumbnail.url, item.user.username); } }); }; this.functionC = function(latitude, longitude, imgurl, user) { var self = this; var latLngPosition = new google.maps.LatLng(latitude, longitude); //Create marker with custom assets marker = new google.maps.Marker({ position:latLngPosition, icon: new google.maps.MarkerImage(imgurl, new google.maps.Size(110, 110), new google.maps.Point(0,0), new google.maps.Point(32, 32)), title: user, map:map }); //Push in array to delete later markersArray.push(marker); }; this.init(); }; $(function() { var app = new app.Application(); }); </code></pre>

    1. COPerhaps try using self.functionC instead of simply functionC?

    2. COI tried that but self refers to the items in the each loop. TypeError: self.functionC is not a function

    3. COI've managed to fix it. Had to pass an anonymous callback function to $.getJSON. Also it would fail as I hadn't included my else statement

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
