Ionic / Angular JS calling the next page by passing a value into a funciton

it should still fix some issue ngClick has direct access to $scope, which means you can't pass interpolated expressions to it (i.e. {{someExpression}}), you can simply pass the object as-is:
HTML
<div ng-repeat="item in countrydata">
  <button ng-click="getStates(item.id)>Get States</button>
</div>
app.controller('SomeController', function($scope){ 
   scope.getStates = function(id) {
       // do stuff with id
   }
})

Calling a vbscript funciton to update a SQL table from an HTML form generated on an asp-classic page


Tag : html , By : Schmidt

it fixes the issue You're trying to mix server-side code with client-side code, and It Don't Work Like ThatTM.
Here's a very rough outline of how you could get information from the user, process it, and display it, all on the same asp page. Note the utter lack of JavaScript. :)
<html>
<head>
<title>My Page</title>
<link rel="stylesheet" type="text/css" href="css/stylestuff.css">
<%
Dim rs, sql, conn
Dim mylist, myval1, myval2, i

myval1 = Request.Form("val1")
myval2 = Request.Form("val2")
'- If the form hasn't been submitted yet, myval1&2 will be the special value Empty, 
'- but you can treat them as a blank string ("") for all intents and purposes.
If Validate(myval1, myval2) = True and myval1 & myval2 <> "" Then
    DoStuffWith myval1, myval2
End If
%>
</head>
<body>
<h1>My Page</h1>
<form method="post" action="">
<p>Select one: <select name="val1" size="1">
    <%
    ListStuff mylist
    For i = 0 to UBound(mylist,1)
        response.write "<option value='" & mylist(0,i) & "'"
        If myval & "" = mylist(0,i) & "" Then response.write " selected"
        response.write ">" & mylist(1,i) & "</option>"
    Next
    %>
    </select></p>
<p>Write something here: 
    <input type="text" name="val2" value="<%=myval2%>" size="10"></p>
<p><input type="submit" name="btn" value="Submit"></p>
</form>
<%
If myval1 & myval2 <> "" Then
    DisplayStuff myval1, myval2
End If
%>
</body>
</html>
<%
Sub ListStuff(L)
    sql = "Select [...] From [...] Where [...]"
    Set rs = Server.Createobject("ADODB.Recordset")
    rs.Open sql, "connection string (or previously-opened connection object)", 1,2
    If Not rs.EOF Then 
        L = rs.GetRows
    Else
        Redim L(1,0)
        L(0,0) = 0 : L(1,0) = "missing!"
    End If
    rs.Close
    Set rs = Nothing
End Sub
'---------------------------------
Function Validate(v1,v2)
dim f
    f = True
    If Not Isnumeric(v1) Then f = False
    If Len(v2) > 10 Then f = False
    Validate = f
End Function
'---------------------------------
Sub DoStuffWith(v1,v2)
    '- table-creation (or whatever) code goes here
End Sub
'---------------------------------
Sub DisplayStuff(v1,v2)
    '- display code goes here
End Sub

Ionic 4 Angular 7 - passing object/data to another page


Tag : ionic-framework , By : Bo.

this one helps. I solved it using a service with a simple setter and getter just like in this question that I later found:
import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root'
})
export class NavExtrasService {

    extras: any;

      constructor() { }

      public setExtras(data){
        this.extras = data;
      }

      public getExtras(){
        return this.extras;
      }
    }
this.navExtras.setExtras(extras)
this.router.navigateByUrl('page-b');
this.location = navExtras.getExtras();

Calling an function that is on an Ionic Angular page from a component in another file

should help you out For this specific need, you first need to understand how components communication work in angular.
In angular components are well-defined, encapsulated units that can communicate with other components but through proper organized manner, not just randomly one components calling methods of other component.
