I'm trying to make a JSON dynamically but when I do something like this:
var jsonVar = {
"section": {}
}
var elementsStoragePrefix = "_app_",
elementName = elementsStoragePrefix + "some_name";
$.extend(jsonVar .section, { elementName: "<option>This is a text</option>"});
I got the key as elementName and not _app_some_name
jsonVar.section =>
Object
elementName: "<option>This is a text</option>"
__proto__: Object
When creating object literals, you don't need to quote the property names, so in your example elementName
will be taken literally. Thankfully, you can use the square-bracket-syntax (or however you spell that):
var extendObject = {};
extendObject[elementName] = '<option>Foobar</option>';
$.extend(jsonVal.section, extendObject);
//or, to use brackets all the way:
$.extend(jsonVal['section'], extendObject);
That should fix things for you
jsonVar.section[elementName] = "<option>This is a text</option>";
