OfficeJs/WordJs select text range by index and bin

Question

1. First, Using OfficeJS/WordJS how can I select text in a paragraph by index and length. For example, my paragraph has 100 characters and I need to select all from index 2 till index 16.
2. Second, When I found this range - how I can add an event handler for this range? I mean, when user click at 2-16 chars in my paragraph - I will show some useful information in my Add-in.

I'm using Word 2016 Add-in. Thanks!

Answer 1

I recommend you to explore the Range functionalities we added as part of the 1.3 update who is in preview right now. Please follow the instructions here on how to try the preview. please explore the added Range object functionalities (all whose Req set are 1.3 in the last column)

Please explore the "split" functionality who enables you to split a paragraph into chunks of ranges when a set of delimiters is provided. For instance you can specify a space (" ") delimiter and get all the words in that paragraph. Check this example (exercise 7 on the lab) that splits a paragraph into words.

In conjunction with the split functionality, you can use getRange and expandTo methods to expand a range. (so you get from index 'x' to 'y'

on your second question. Once you have the range, you can wrap it with a titled content control (range.insertContentControl and then specify a title for it), so that you can use the Office.context.bindings.addToNamedItemAsync API to create a Textbinding and subscribe to the BindingSelected event, as shown on this example.

Hope this guides you in the right direction.
