I have an input field coded as the following:

1. <input type="radio" name="03794" class=" js-sourcing-option" data-sourcingoption="{"hasBackOrder":true,"isPartial":false,"unsourcedQty":0,"warehouseSequences":[1],"shipments":{"2017-10-12T17:00:00":{"warehouseNumber":101,"deliverByTime":"2017-10-12T17:00:00","numShipments":0,"warehouseQty":0,"backorderQty":1,"qtyByWarehouseInStock":{},"qtyByWarehouseBackorder":{"101":1}}},"sourcedQty":1,"shouldDisplay":true}">

Using jQuery, I cannot figure out how to get the value of " deliverByTime" (which should equal " 2017-10-12T17:00:00") buried deep within the " data-sourcingoption" attribute of this field.

The following will successfully output the "name" attribute:

(the "[0]" is there below because there are more of these on the page)

1. $('input.js-sourcing-option')[0]["name"]
2. // Output: 03794

But if I do a similar thing for "data-sourcingoption" to try and play with the results and extract what I need, I get this:

1. $('input.js-sourcing-option')[0]["data-sourcingoption"]
2. // Output: undefined

Any help would be greatly appreciated...thank you!
