What is the simplest way to dynamically load a table from a local JSON file?
I have struggled for hours to do this without any luck and would appreciate
some insight.
Below is a sample that works when referencing an embedded javascript array
object (data):
qx.Class.define("iveware.Application",
{
extend : qx.application.Standalone,
members :
{
main : function()
{
var data = [
{id:3, variable:"age", label:"",variableType:"", restrict:"",
bounds:""},
{id:4, variable:"gender", label:"",variableType:"", restrict:"",
bounds:""},
{id:5, variable:"race3", label:"",variableType:"", restrict:"",
bounds:""},
{id:6, variable:"hyper", label:"",variableType:"", restrict:"",
bounds:""},
{id:7, variable:"diab", label:"",variableType:"", restrict:"",
bounds:""},
{id:8, variable:"smoke", label:"",variableType:"", restrict:"",
bounds:"" },
{id:9, variable:"numcig", label:"",variableType:"", restrict:"",
bounds:""},
{id:10, variable:"yrssmoke", label:"",variableType:"", restrict:"",
bounds:""},
{id:11, variable:"fatindex", label:"Fatindex scale",variableType:"",
restrict:"", bounds:""},
{id:12, variable:"fammi",label:"",variableType:"", restrict:"",
bounds:"" },
{id:13, variable:"edusubj3",label:"",variableType:"", restrict:"",
bounds:"" },
{id:14, variable:"dha_epa", label:"Dietary N-3
intake",variableType:"", restrict:"", bounds:""},
{id:15, variable:"redtot", label:"Red cell membrane
value",variableType:"", restrict:"", bounds:""},
{id:16, variable:"cholesth",label:"",variableType:"", restrict:"",
bounds:""}
];
this.base(arguments);
if (qx.core.Variant.isSet("qx.debug", "on"))
{
qx.log.appender.Native;
qx.log.appender.Console;
}
var win = new qx.ui.window.Window("Variable Parameters").set({
layout : new qx.ui.layout.Grow(),
allowClose: true,
allowMinimize: false,
contentPadding: 0
});
this.getRoot().add(win);
win.moveTo(200, 200);
win.open();
var tableModel = new qx.ui.table.model.Simple();
tableModel.setColumns([ "ID", "Variable", "Label", "VariableType",
"Restrict", "Bounds"],
[ "id", "variable", "label", "variableType",
"restrict", "bounds"]);
tableModel.setDataAsMapArray(data);
tableModel.setColumnEditable(1, true);
var table = new qx.ui.table.Table(tableModel).set({
decorator: null
})
win.add(table);
var tcm = table.getTableColumnModel();
}
}
});
I would like to instead take from a local JSON file:
http://n2.nabble.com/file/n4450668/data2.json data2.json
and do something like:
var url = "data/data2.json";
var dtaController = new qx.data.controller.Object();
var store = new qx.data.store.Json(url);
tableModel.setDataAsMapArray(store.getModel());
to initialize the table.
