Retrieving data from Dojo's JsonRest and storing it as an object variable

Question

Retrieving data from Dojo's JsonRest and storing it as an object variable

After reading this post on Stack Overflow about how to Remove String from JSON, I am looking to populate a Dojo Selectbox with JSON Data. However, I am facing an issue where I need to modify the JSON Data before passing it to the dijit.form.select Box.

The data is retrieved using JsonRest. My question is, how can I load the JSON Data into a regular object variable? I attempted the code below but it did not yield the desired results.

var processStore = new JsonRest({
            target: "http://cnwin.ebusiness.local/activiti-rest/service/repository/process-definitions?startableByUser=kermit", 
            headers: {"Authorization": "Basic a2VybWl0Omtlcm1pdA=="}, 
            allowNoTrailingSlash: false
            });

var processes = processStore.query("",{});

My goal is simple - to retrieve JSON data from the JsonRest store and store it in a regular variable.

Thank you

The JsonRest store requires an array input, which means that if your data is not in the correct format, the store will not be able to retrieve it for you.

If you only need to read the data and not perform any other operations like updating or deleting, one way to achieve this is by making an AJAX request to fetch the data and manually populating a dojo/store/Memory store. Here's an example:

require([ "dojo/request/xhr", "dojo/store/Memory" ], function(xhr) {
    var url = "http://cnwin.ebusiness.local/activiti-rest/service/repository/process-definitions?startableByUser=kermit";

    xhr(url, {
        handleAs: json
    }).then(function(data) {
        if (data.data !== undefined) {
            var myStore = new Memory({
                data: data.data
            });
            // Manipulate "myStore" as needed
    });
});

If you want to explore the full functionality of the JsonRest store, you may need to customize it according to your requirements. By examining the code, you can see various AJAX requests in methods such as:

get()
put()
remove()
query()

You have the option to create your own store and extend these methods based on your specific needs.
