javascript - expoting big data to csv file - carshes -


im trying export big data csv files. (above 20000 lines... can on 100000 lines easily). after try download file, crashes - download failed due network failures. (managed download 18000 lines file, weighs 1.7mb, code worked perfectly. above 20000 download crashes)

heres code... thanks!

edit- works on ie, doesnt work in chrome

var data2 =     [[data12]]; var csvcontent2 = ""; data2.foreach(function (infoarray, index) {      datastring = array.prototype.join.call(infoarray, "");     csvcontent2 += index < data2.length ? datastring + '\n' : datastring;  });  var download = function(content, filename, mimetype) { var = document.createelement('a');     mimetype = mimetype || 'application/octet-stream';      if (navigator.mssaveblob) { // ie10         return navigator.mssaveblob(new blob([content], { type: mimetype }), filename);     } else if ('download' in a) { //html5 a[download]         a.href = 'data:' + mimetype + ',' + encodeuricomponent(content);         a.setattribute('download', filename);         document.body.appendchild(a);         settimeout(function() {         a.click();         document.body.removechild(a);         }, 66);     return true; } else { //do iframe dataurl download (old ch+ff):     var f = document.createelement('iframe');     document.body.appendchild(f);     f.src = 'data:' + mimetype + ',' + encodeuricomponent(content);      settimeout(function() {         document.body.removechild(f);     }, 333);     return true;     } }      download(csvcontent2, 'groupb.csv', 'text/csv');

warning, there limits url, example total length of url including get, must not exceed 2000+ characters on ie, maybe you'll hit maximum size large csv file ?
how long uri ? see this link ie uri limit.

edit : maybe can try createobjecturl(blob), not stabilized feature :x

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

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
