Sometimes it’s easier for you, as a developer, to investigate Custom JavaScript issues by viewing the widgets through the Debugging Mode in your browser. Our developers add debugging logs for almost all methods that widgets execute. You can view these logs in your Developer Console using the following methods.
Via URL Parameter
You can enable it by simply adding ?debug=1 as an extra URL parameter.
Via Global Variable
Or you can enable it by adding the following JavaScript global variable. You must place it before the widget embed code.
You can use the Code Editor to modify both your Custom CSS, HTML and JavaScript. The CSS editor supports LESS CSS pre-processor. That means you can use both traditional CSS syntax and the better LESS syntax.
Fork from Nosto's UGC
You can now also click the fork link at the top-right corner of each editor pane. This brings the boilerplate code from the Nosto's UGC codebase so that you don't need to write from scratch or copy & paste from our Developer Portal.
Customize Inline Tiles
All inline tiles reside in an Iframe with the widgetapp.stackla.com URL. You can't just write JavaScript on your website to access it because of browser security restrictions. The only way to access it is via our Code Editor.
Boilerplate
To quickly get started with Custom Expanded Tile JavaScript, you can fork or copy & paste the following code into the editor.
$.extend(Callbacks.prototype, {
onCompleteJsonToHtml: function (tileObject, t) {
return tileObject;
},
onCompleteRenderImage: function(img) {
},
// tiles is a jQuery array object, use tiles. each when traversing
onCompleteAddingToDom: function (tiles) {
},
//Call first, before render/window resize
onBeforeRenderIsotope: function (containerWidth, maxTileWidth, margin, numColumns, currentTileWidth) {
//Can be used to handle break-points for responsiveness, for example:
/*
if (containerWidth > 900) {
var columns = 6;
return {
tileWidth: Math.floor(((containerWidth - margin) / columns) - margin);
numColumns: columns
}
} else {
var columns = 3;
return {
tileWidth: Math.floor(((containerWidth - margin) / columns) - margin);
numColumns: columns
}
}
*/
// return tile width, the isotope will be init as tile width + margin
return {
tileWidth: currentTileWidth,
numColumns: numColumns
}
},
// call second, before each tile width and height is set
getTileWidth: function (tile, tileWidth, margin, numColumns) {
// return tile width
return tileWidth;
},
//Call third, after tile width and height are set
onCalculateDimensions: function (tile) {
},
// After the filtering changed
onCompleteChangeFilter: function (tiles, prevFilterId, nextFilterId) {
},
// Before more tiles are rendered
onBeforeRenderTiles: function (addedIds, addedData) {
},
// After more tiles are rendered
onCompleteRenderTiles: function ($addedTiles, addedData) {
},
// Triggers when it's the end of the scrolling
onScrollLoad: function (tiles, jsLoading) {
},
// Triggers when it's the end of the scrolling
onScrollEnd: function (tiles, jsLoading) {
},
// Triggers when the parent page triggers a customized postMessage
onMessage: function (type, data) {
}
});
//======================
// Customisable Strings
//======================
Strings.load_more = 'Load more content';
Strings.scroll_load = 'Loading...';
Strings.scroll_end = 'There is no more content to be displayed.';
We would recommend the use of our Expanded Tile Code Editor when customizing your Expanded Tiles. However, as the Widget Expanded Tiles are rendered in their parent page, you can also customize them by adding JavaScript to your parent page HTML.
Boilerplate
To quickly get started with Custom Expanded Tile JavaScript, you can fork or copy and paste the following code into the editor.

We provide a Blank Canvas widget so that you can build your widget when you find that the current UGC Widgets don't fit your customization needs.
Boilerplate
To quickly get started with the Blank Canvas widget customizations, you can copy and paste the following code into the Custom Code Editor in Nosto's UGC.
