Filter json array using another json array

how to filter json array using another json array? (it is not working without id)

You could filter the items in the result array where the item matches every parameter in filterParams. If you only want to check if at least one match exists replace .filter with .some

e.g.

var matches = results.filter(item =>
  filterParams.every(paramItem =>
    item[paramItem.param] === paramItem.value));

I've limited it to equals comparison but you can expand the comparison using a switch based on the other comparison types you have.

How to filter an json object by another object - Javascript

You can use every and includes to make a boolean value that will work with filter().

For example:

var jsondata = [{"firstName": "Sam","lastName": "Jones","age": "10"},{"firstName": "Sam1","lastName": "Jones1","age": "10"},{"firstName": "Sam2","lastName": "Jones2","age": "12"},{"firstName": "Sam3","lastName": "Jones3","age": "13"},{"firstName": "Sam4","lastName": "Jones4","age": "14"},{"firstName": "Sam5","lastName": "Jones5","age": "15"},{"firstName": "Sam","lastName": "Jones11","age": "16"},{"firstName": "Sam6","lastName": "Jones6","age": "17"},{"firstName": "Sam7","lastName": "Jones7","age": "18"},{"firstName": "Sam8","lastName": "Jones8","age": "19"},{"firstName": "Sam9","lastName": "Jones9","age": "20"},{"firstName": "Sam10","lastName": "Jones10","age": "21"},{"firstName": "Sam11","lastName": "Jones11","age": "22"},{"firstName": "Sam12","lastName": "Jones12","age": "23"}]
  
var filterArray = [{"id":"firstName","value":["Sam"]},{"id":"lastName","value":["Jones"]}]

let filtered = jsondata.filter(item =>        // filter jsondata
       filterArray.every( f =>                // so every member of filter array
            f.value.includes(item[f.id])) )   // has a corresponding item[id] in value

console.log(filtered)

The above filter says that for every item in filterArray you want the value array to include the item keyed to id. This will make it so the item in jsondata needs to match all the criteria in filterArray. If you add Sam1 and Jones1 to the arrays, you'll get two items in the filter.

var jsondata = [{"firstName": "Sam","lastName": "Jones","age": "10"},{"firstName": "Sam1","lastName": "Jones1","age": "10"},{"firstName": "Sam2","lastName": "Jones2","age": "12"},{"firstName": "Sam3","lastName": "Jones3","age": "13"},{"firstName": "Sam4","lastName": "Jones4","age": "14"},{"firstName": "Sam5","lastName": "Jones5","age": "15"},{"firstName": "Sam","lastName": "Jones11","age": "16"},{"firstName": "Sam6","lastName": "Jones6","age": "17"},{"firstName": "Sam7","lastName": "Jones7","age": "18"},{"firstName": "Sam8","lastName": "Jones8","age": "19"},{"firstName": "Sam9","lastName": "Jones9","age": "20"},{"firstName": "Sam10","lastName": "Jones10","age": "21"},{"firstName": "Sam11","lastName": "Jones11","age": "22"},{"firstName": "Sam12","lastName": "Jones12","age": "23"}]
  
var filterArray = [{"id":"firstName","value":["Sam", "Sam1"]},{"id":"lastName","value":["Jones", "Jones1"]}]

let filtered = jsondata.filter(item =>        // filter jsondata
       filterArray.every( f =>                // so every member of filter array
            f.value.includes(item[f.id])) )   // has a corresponding item[id] in value

console.log(filtered)

Locate the PTC\PTC folder and add that folder to Code.
Select File | Save Workspace As... from the menu. Give it a name such as ptc-workspace.

Add Bootstrap & jQuery

npm install bootstrap@3 jquery --save

generate service without create a folder underneath:

ng g s security/security --flat -m app.module

//--flat means on underneath folder  generated
//-m app.module means registering this new service with the app.module

create a derective:

A Very Simple Popup Box – HTML, CSS, JavaScript

A Very Simple Popup Box – HTML, CSS, JavaScript

Popup boxes are the most useful way of showing a warning or any other important information to the website visitors in many HTML5 templates. In this article I’m going to walk you through the creation of a very simple popup box with shadow overlay and close button. We’re going to implement this using HTML, CSS and jQuery in less than 100 lines (not compressed code).

The box and the shadow is hidden when the page loads, we have to trigger an event, like a link click to show it.
Use the iframe below to test the live demo:

The HTML Code

Add a link that triggers the box and a div that behaves like the box shadow. This wraps the actual box with the close button. The helper span is used to center the box vertically.

<a class="trigger_popup_fricc">Click here to show the popup</a>

<div class="hover_bkgr_fricc">
    <span class="helper"></span>
    <div>
        <div class="popupCloseButton">X</div>
        <p>Add any HTML content<br />inside the popup box!</p>
    </div>
</div>

The CSS Code

/* Popup box BEGIN */
.hover_bkgr_fricc{
    background:rgba(0,0,0,.4);
    cursor:pointer;
    display:none;
    height:100%;
    position:fixed;
    text-align:center;
    top:0;
    width:100%;
    z-index:10000;
}
.hover_bkgr_fricc .helper{
    display:inline-block;
    height:100%;
    vertical-align:middle;
}
.hover_bkgr_fricc > div {
    background-color: #fff;
    box-shadow: 10px 10px 60px #555;
    display: inline-block;
    height: auto;
    max-width: 551px;
    min-height: 100px;
    vertical-align: middle;
    width: 60%;
    position: relative;
    border-radius: 8px;
    padding: 15px 5%;
}
.popupCloseButton {
    background-color: #fff;
    border: 3px solid #999;
    border-radius: 50px;
    cursor: pointer;
    display: inline-block;
    font-family: arial;
    font-weight: bold;
    position: absolute;
    top: -20px;
    right: -20px;
    font-size: 25px;
    line-height: 30px;
    width: 30px;
    height: 30px;
    text-align: center;
}
.popupCloseButton:hover {
    background-color: #ccc;
}
.trigger_popup_fricc {
    cursor: pointer;
    font-size: 20px;
    margin: 20px;
    display: inline-block;
    font-weight: bold;
}
/* Popup box BEGIN */

The Script

$(window).load(function () {
    $(".trigger_popup_fricc").click(function(){
       $('.hover_bkgr_fricc').show();
    });
    $('.hover_bkgr_fricc').click(function(){
        $('.hover_bkgr_fricc').hide();
    });
    $('.popupCloseButton').click(function(){
        $('.hover_bkgr_fricc').hide();
    });
});
