What is the best way to retrieve data for a Dojo Dgrid Table using AJAX?

Currently, I am in the process of considering DGrid for my web application. My goal is to create a table layout similar to the one demonstrated here. For reference, the code for the example can be found here.

The table in question utilizes a memory store to populate its data - the information displayed in the summary field is what is shown when each row is expanded upon clicking.

My intention is to have the details (i.e., the content displayed when a row is clicked) dynamically fetched from the server upon row interaction, instead of being statically loaded with the rest of the page. How should I go about modifying the existing code to achieve this functionality?

(I am looking to create an HTML table where each row can be expanded upon clicking, with the content for each expansion retrieved from the server using AJAX. I am considering dgrid as a viable option due to its ability to provide sortable columns. However, if there is a more suitable alternative, please feel free to recommend it).

EDIT: My main objective is to gather insights on possible approaches, rather than expecting someone to provide the specific code. Since I am not very familiar with Dojo, I am unsure of the most appropriate method to follow.

Answer №1

When your ajax request brings back html content, consider incorporating a dijit/layout/ContentPane into your renderer. Set the URL of the desired content to fetch in the href property of the ContentPane. Suppose your initial data (similar to the memory store in the example) includes a property named "yourServiceCallHref" containing the URL for lazy loading, you can attempt this:

require(["dijit/layout/ContentPane", ...], function(ContentPane){

    renderers = {
        ...,
        table: function(obj, options){
            var div = put("div.collapsed", Grid.prototype.renderRow.apply(this, arguments)),
                cp = new ContentPane({
                    href : obj.yourServiceCallHref
                }),                       
                expando = put(div, "div.expando", cp.domNode);
                cp.startup();
        return div;
    }
});

If your service returns JSON data, you might be able to utilize dojo/request in a similar manner. Simply include your DOM creation steps in your request callback and place them within the "expando" div...

Another approach could involve substituting the Memory store with a JsonRest store, and ensuring that the server outputs data in the same JSON format as seen in the Memory store. This means that all data would be fetched in a single call...
