I have an email component (email-tag.html) that consist of a label, a select and a delete button element.
The email-tag.html component is hosted in its parent email-view-tag.html. email-view-tag contains an add-email-button that adds the email-tag element to the DOM each time it is clicked.
I need help in removing an added email-tag component when its delete-button is clicked. It is the compnoent that contains the delete-button that should be removed.
The two components are shown below:
email-tag.html
<!DOCTYPE html>
<polymer-element name='email-tag'>
<template>
<style>
.main-flex-container
{
display:flex;
flex-flow:row wrap;
align-content:flex-start;
}
.col
{
display:flex;
flex-flow:column;
align-content:flex-start;
flex-grow:1;
}
</style>
<div id='email' class='main-flex-container'>
<section id='col1' class='col'>
<input id=emailTxt
type='text'
list='_emails'
value='{{webContact.homeEmail}}'>
<datalist id='_emails'>
<template repeat='{{email in emails}}'>
<option value='{{email}}'>{{email}}</option>
</template>
</datalist>
</section>
<section id='col2' class='col'>
<button id='delete-email-btn' type='button' on-click='{{deletePhone}}'>Delete</button>
</section>
</div>
</template>
<script type="application/dart">
import 'package:polymer/polymer.dart' show CustomTag, PolymerElement;
import 'dart:html' show Event, Node;
@CustomTag( 'email-tag' )
class EmailElement extends PolymerElement
{
//@observable
EmailElement.created() : super.created();
List<String> emails = [ '', 'Home', 'Personal', 'Private', 'Work', ];
void deletePhone( Event e, var detail, Node target)
{
//shadowRoot.querySelector('#new-phone' ).remove();
//print( 'Current row deleted' );
}
}
</script>
</polymer-element>
email-view-tag.html
<!DOCTYPE html>
<link rel="import" href="email-tag.html">
<polymer-element name='email-view-tag'>
<template>
<style>
.main-flex-container
{
display:flex;
flex-flow:row wrap;
align-content:flex-start;
}
.col
{
display:flex;
flex-flow:column;
align-content:flex-start;
flex-grow:1;
}
</style>
<div id='email-view' class='main-flex-container'>
<section id='row0' >
<button id='add-email-btn' type='button' on-click='{{addPhone}}'>Add Phone</button>
</section >
<section id='rows' class='col'>
<!-- <epimss-phone-header-tag id='col1' class='col'></epimss-phone-header-tag> -->
</section>
</div>
</template>
<script type="application/dart">
import 'package:polymer/polymer.dart' show CustomTag, PolymerElement;
import 'dart:html' show Event, Node, Element;
@CustomTag( 'email-view-tag' )
class EmailViewElement extends PolymerElement
{
//@observable
EmailViewElement.created() : super.created();
void addPhone( Event e, var detail, Node target )
{
$[ 'rows' ].children.add( new Element.tag( 'email-tag' ) );
}
@override
void attached() {
super.attached();
$[ 'add-email-btn' ].click();
}
}
</script>
</polymer-element>
The application does execute normally and clicking the add button does add the email component. The delete button does not work - it is here I am asking for help.
Thanks
