I am trying to implement a complex grid that has 4 functions defined, on dataBound, columnMenuInit, and 2 on change. We noticed that, when using setOptions/getOptions from local storage, the functionality of our column menu is lost (an error about t[e] not being defined pops up).
Now, I have researched and apparently the JSON.stringify we have to apply before storing does away with the functions, this is, they are lost when setting the options to local storage: however, I was trying to implement a workaround I saw while researching, where basically the function was stored separately, and added after parsing the rest of the options before loading them to the grid again.
My problem now is that the function is getting added to the parsed options object as what I believe is an Unicode string (the representation of it on Chrome dev tools comes up as a string instead of a function). The error thrown when trying to JSON.parse it is that there's a "u" token at position 1, so that's what leads me to think in this way.
My question is: is there any way I can assign the function stored separately on local storage to grid options before applying them to the grid, in order to not lose any functionality? I would be happy just storing and re-adding the columnMenu function (I guess I could extend this to the other ones if it's possible, later on). What would be your advice in this case?
