I would like to make the path to data contained in JSON variable. The code I have now looks like this:
function writeDB(block)
{
$.getJSON('js/data.js', function(data) {
if (block == "path1") { var adr = data.test.path1.db; };
if (block == "path2") { var adr = data.test.path2.db; };
if (block == "path3") { var adr = data.test.path3.db; };
var datastring="";
$.each(adr, function(i, field){
temp = encodeURIComponent($("#writeDB_"+block+" [name="+adr[i].abc+"]").val());
datastring += adr[i].abc+"="+temp+"&";
});
});
}
The "if" parts I would like to simplify and make it variable, by using the variable 'block' directly into the "adr" path, something like this
var adr = "data.test."+block+".db";
But a string won't work, so its useless. Someone knows how I can fix that?

JSONPath is a query language for JSON with features similar to XPath for XML. JSONPath is used for selecting and extracting a sub-section from the JSON document. 1. JSONPath Dependencies
If you want to access data from the profile object or data from the User Profile created with the Profiles API, use a full JSONPath expression such as $.profile.someProp. IE if you wanted to access the email, you could use the expression $.profile.email.
The dollar sign is followed by a sequence of child elements, which are separated via dot (code) notation or via the square brackets (code). The important JSONPath syntax rules are:
The variableID refers to entries in the inputs section of launch.json and tasks.json, where additional configuration attributes are specified. The following example shows the overall structure of a tasks.json that makes use of input variables: Currently VS Code supports three types of input variables:
You want to use square bracket notation:
var adr = data.test[block].db;
if (typeof(data.test[block]) != "undefined")
var adr = data.test[block].db;
