.js to .json

[RickeyFight]

I know this is stupid but I cannot figure out how to get my js to pull some of my config.json into it.

Does it have to be a function?

After viewing sample code, I see that it can be done with a function.

LocalLayer widget:

this.config.layers.layer.forEach(function (layer) {

Is there any documentation/ videos/ examples on how this can be done.

I am looking for a way to amend the config json and have the script reflect that.

Such as

js

var Exp = "fromjson";

json

"fromjson": "crime = 'Larceny/Theft' ",

Thanks!

Rickey,

   In a widget.js there is access to the widgets config.json by using the this.config object so if you have a object called crimes in your config.json then you can access this in the widget.js by using this.config.crimes.

Robert,

Thank you! I have tried that. I just keep getting an error of crimes not defined (assuming crimes is in my config.json).

[RobertScheitlin__GISP]

Rickey,

   Can You show me how you have "crimes" written in your json file?

[RickeyFight]

Robert,

json

"crimes": "Month='January'"

widget

this.config.crimes

[RobertScheitlin__GISP]

Rickey,

   Is crimes a child of some other object? Can you share your whole json?

[RickeyFight]

Robert,

Here is my json

I am assuming that if i wanted to do the layer in my json my code would be this.config.layers.layer

{ "crimes": "Month='January'",

    "layers": {
        "layer": [

I was having that same problem for a while. I think what I did to fix it was assign a variable in the js to the config value and then used the variable in the js code.

for example:

json

"crimes": "Month='January'"

widget

var crimeDate = this.config.crimes;

Then use crimeDate in the js code where you had "this.config.crimes" before.

Stan,

I tired that, my error is:

Rickey,

   I don't see anything wrong in your json so the next question is where in your widget.js are you trying to access the this.config.crimes object (hopefully after postCreate method)?
