datatables - How to display the column headers dynamically in jquery data table -


i have below code displaying array of objects having property , value in data table. here column headers hardcoded seen in below html code. how can make dynamic based on input dataset? 

 var dataset = [{   "latitude": 18.00,   "longitude": 23.00,   "name": "pune" }, {   "latitude": 14.00,   "longitude": 24.00,   "name": "mumbai" }, {   "latitude": 34.004654,   "longitude": -4.005465,   "name": "delhi" },{   "latitude": 23.004564,   "longitude": 23.007897,   "name": "jaipur" }]; $(document).ready(function() {     $('#example').datatable( {         data: dataset,         "columns": [             { "data": "name" ,"title":"custom name"},             { "data": "latitude" },             { "data": "longitude" },          ]     } ); } );     <table id="example" class="display" cellspacing="0" width="100%">         <thead>             <tr>                 <th>name</th>                 <th>latitude</th>                 <th>longitude</th>              </tr>         </thead>      </table>

assuming structure of objects in dataset not change, use first object build json object external datatable declaration. if objects not of consistent structure, can tweak logic inside $.each structure handle that.

here's quick hack:

var dataset = [{   "latitude": 18.00,   "longitude": 23.00,   "name": "pune" }, {   "latitude": 14.00,   "longitude": 24.00,   "name": "mumbai" }, {   "latitude": 34.004654,   "longitude": -4.005465,   "name": "delhi" }, {   "latitude": 23.004564,   "longitude": 23.007897,   "name": "jaipur" }];  var my_columns = [];  $.each( dataset[0], function( key, value ) {         var my_item = {};         my_item.data = key;         my_item.title = key;         my_columns.push(my_item); });  $(document).ready(function() {   $('#example').datatable({     data: dataset,     "columns": my_columns   }); });

you should consider removing static table content in html this

<table id="example" class="display" cellspacing="0" width="100%"></table>

here's jsfiddle https://jsfiddle.net/z4t1po8o/18/

have fun.

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
