ionic3 - Ionic2 button click text box toggle -


i beginner in ionic. wants toggle textbox(ion-input) on button click. sending following code not working. please suggest suggestion solve it.the openthetextbox function change hide boolean variable opposite. every time ion-input invisible state.

html file 

<ion-header>  <ion-navbar>  <button ion-button menutoggle>  <ion-icon name="menu"></ion-icon>  </button>  <ion-title>home</ion-title>  </ion-navbar> </ion-header>  <ion-content padding>  <h3>ionic menu starter</h3>  <p>     if lost, <a      href="http://ionicframework.com/docs/v2">docs</a> show way.  </p>   <button ion-button secondary menutoggle round>toggle menu</button>   <button ion-button color="secondary" round full  (click)="openthetextbox()" >add </button>   <ion-input type="text" value="asdasdasd" *ngif="hide"></ion-input>   <ion-list>    <button ion-item *ngfor="let item of dataarray" >    {{ item.user_name }}   </button>    </ion-list>  </ion-content>

ts file

import { component } '@angular/core'; import { navcontroller } 'ionic-angular'; import { mydataprovider } '../../providers/my-data/my-data';  @component({   selector: 'page-home',   templateurl: 'home.html' }) export class homepage {  public dataarray: array<object>; public hide: boolean = true; constructor(public navctrl:  navcontroller,mydataprovider:mydataprovider) { alert("home page"); type product = { name: string; user_name: string; location: string }; let passdataobject =  { name: "jit", user_name: "j.comp", location:  "kolkata" }; // mydataprovider.savetablicatosqlite(passdataobject); let jitsavedata = mydataprovider.gettablicamyofflinedata().then( (result)=>{ this.dataarray = <array<object>> result; alert("length of array "+this.dataarray.length) }, (error) => { console.log("error: ", error); });  }  openthetextbox() {  alert("openthetextbox");  this.hide = !this.hide; }  }

change ion-input this:

<ion-input type="text" value="asdasdasd"  [class.hidden]="hide"></ion-input>

or hide== true. ever works you.

then .scss, add:

page-home {     ion-input.hidden {         display: none;     } }

the point have conditional class when apply class named "hidden". ngif condition "if html shoud rendered", if happens tag not rendered because of condition, won't have rendered anymore. basically, have rendered @ first place , hide boolean property can toggled.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
