javascript - KnockoutJS Populate observableArray using TypeScript -

-

how can populate observablearray (knockoutjs) using typescript? have class viewmodel.

without typescript load data using $.getjson(); , map it.

function viewmodel() {     var self = this;      self.list_data = ko.observablearray([]);      $.getjson('/home/get', function (data) {         var mapped = $.map(data, function (obj) { return new aclass(obj); });         self.list_data(mapped);     }); }

this class far, loading data in constructor , json data array. have tried map no luck.

how store/map in list_data = ko.observablearray([]); in typescript class?

class myviewmodel {     constructor() {         $.getjson('/home/get', function (data) {             alert(data);         });     }      list_data = ko.observablearray([]); }

thanks

edit:

here data server:

[{ "product": "102289", "artworkid": 19431, "isdownloaded": 1 },     { "product": "272203", "artworkid": 19423, "isdownloaded": 1 },     { "product": "272222", "artworkid": 20306, "isdownloaded": 1 },     { "product": "332245", "artworkid": 19430, "isdownloaded": 1 },     { "product": "382277", "artworkid": 19424, "isdownloaded": 0 },     { "product": "382256", "artworkid": 19425, "isdownloaded": 1 },     { "product": "392272", "artworkid": 19416, "isdownloaded": 1 },     { "product": "422242", "artworkid": 19422, "isdownloaded": 1 },     { "product": "452295", "artworkid": 19414, "isdownloaded": 0 },     { "product": "452219", "artworkid": 19421, "isdownloaded": 0 },     { "product": "452214", "artworkid": 19413, "isdownloaded": 0 },     { "product": "452223", "artworkid": 19415, "isdownloaded": 1 },     { "product": "632204", "artworkid": 20051, "isdownloaded": 1 },     { "product": "632238", "artworkid": 19432, "isdownloaded": 1 },     { "product": "632295", "artworkid": 19419, "isdownloaded": 1 },     { "product": "712220", "artworkid": 19417, "isdownloaded": 1 },     { "product": "722240", "artworkid": 19433, "isdownloaded": 1 },     { "product": "762258", "artworkid": 20273, "isdownloaded": 0 },     { "product": "762278", "artworkid": 20274, "isdownloaded": 1 },     { "product": "792297", "artworkid": 19418, "isdownloaded": 1 },     { "product": "812202", "artworkid": 19429, "isdownloaded": 0 },     { "product": "862280", "artworkid": 19420, "isdownloaded": 1 }]

this how in typescript:

class myviewmodel {     list_data = ko.observablearray([]);     constructor() {          $.getjson('/home/get', data => {             var mapped = $.map(data, obj => new aclass(obj));             this.list_data(mapped);         });     } }

this compile into:

var myviewmodel = (function () {     function myviewmodel() {         var _this = this;         this.list_data = ko.observablearray([]);         $.getjson('/home/get', function (data) {             var mapped = $.map(data, function (obj) { return new aclass(obj); });             _this.list_data(mapped);         });     }     return myviewmodel; })();

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
