javascript - Not able to replace all occurence of a json key correctly -


hi have nested json object.

i want rename occurrences of total_exec_qty_buy & total_exec_qty_sell total_exec_qty; total_num_ords_buy & total_num_ords_sell total_num_ords

i'm doing in following way:

newarray = json.stringify(newarray).split('"total_exec_qty_buy":').join('"total_exec_qty":');

when 1 statement(above one) output fine. when this:

newarray = json.stringify(newarray).split('"total_exec_qty_buy":').join('"total_exec_qty":');      newarray = json.stringify(newarray).split('"total_exec_qty_sell":').join('"total_exec_qty":'); newarray = json.stringify(newarray).split('"total_num_ords_buy":').join('"total_num_ords":');     newarray = json.stringify(newarray).split('"total_num_ords_sell":').join('"total_num_ords":');

then output:

"\"\\\"[{\\\\\\\"total_wt_arr_slp_buy\\\\\\\":\\\\\\\"-1.9322\\\\\\\",\\\\\\\"total_exec_qty\\\\\\\":\\\\\\\"49654\\\\\\\",\\\\\\\"total_wt_buy\\\\\\\":\\\\\\\"0.31\\\\\\\",\\\\\\\"total_wt_arr_last_slp_buy\\\\\\\":\\\\\\\"-0.1924\\\\\\\",\\\\\\\"total_wt_ivwap_slp_buy\\\\\\\":\\\\\\\"-0.1103\\\\\\\",\\\\\\\"total_exec_val_buy\\\\\\\":\\\\\\\"3224372.00\\\\\\\",\\\\\\\"total_ord_qty_buy\\\\\\\":\\\\\\\"61688\\\\\\\",\\\\\\\"total_num_ords_buy\\\\\\\":\\\\\\\"859\\\\\\\"},{\\\\\\\"total_wt_arr_last_slp_sell\\\\\\\":\\\\\\\"-1.2509\\\\\\\",\\\\\\\"total_ord_qty_sell\\\\\\\":\\\\\\\"139654\\\\\\\",\\\\\\\"total_exec_qty_sell\\\\\\\":\\\\\\\"111012\\\\\\\",\\\\\\\"total_wt_ivwap_slp_sell\\\\\\\":\\\\\\\"-0.1833\\\\\\\",\\\\\\\"total_wt_sell\\\\\\\":\\\\\\\"0.69\\\\\\\",\\\\\\\"total_exec_val_sell\\\\\\\":\\\\\\\"7129344.00\\\\\\\",\\\\\\\"total_num_ords_sell\\\\\\\":\\\\\\\"1099\\\\\\\",\\\\\\\"total_wt_arr_slp_sell\\\\\\\":\\\\\\\"-2.4978\\\\\\\"},{\\\\\\\"total_wt_arr_last_slp\\\\\\\":\\\\\\\"-0.9213\\\\\\\",\\\\\\\"total_exec_qty\\\\\\\":\\\\\\\"160666\\\\\\\",\\\\\\\"total_wt_ivwap_slp\\\\\\\":\\\\\\\"-0.1606\\\\\\\",\\\\\\\"total_wt_arr_slp\\\\\\\":\\\\\\\"-2.3216\\\\\\\",\\\\\\\"total_ord_qty\\\\\\\":\\\\\\\"201342\\\\\\\",\\\\\\\"total_num_ords\\\\\\\":\\\\\\\"1958\\\\\\\",\\\\\\\"total_notional\\\\\\\":\\\\\\\"10353698.63\\\\\\\"}]\\\"\""

why happening??

this happening because keep calling json.stringify().

stringify json object once , use str.replace() instead:

var jsonstr = json.stringify(jsonobj); jsonstr = jsonstr.replace("total_exec_qty_buy", "total_exec_qty");     jsonstr = jsonstr.replace("total_exec_qty_sell", "total_exec_qty");  jsonstr = jsonstr.replace("total_num_ords_buy", "total_num_ords");  jsonstr = jsonstr.replace("total_num_ords_sell", "total_num_ords");

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
