Having trouble using Jquery Selector to locate a div element in my Polymer project. Seems like it should be simple, but I can

Purpose: My objective is to add a new class to the div that contains a form when a specific icon is clicked. Challenge: The Jquery selector in pullupClose function is not able to identify the element. Check out the console.log result for a visual representation of the issue. Since the element cannot be fetched successfully, the addClass function does not work as intended. Can someone help me identify and fix the mistake I may have made? Thanks in advance!

HTML

<div class="sidepullup" id="idSidePullup">
            <iron-icon class="cross" on-click="pullupClose" icon="close"></iron-icon>
            <iron-form id="idForm">
                <form action="/">
                    <paper-input type"text" label="First Name"></paper-input>
                    <paper-input type="text" label="Last Name"></paper-input>
                    <paper-input type="text" label="Title"></paper-input>
                    <paper-input type="text" label="About"></paper-input>
                    <paper-button style="background-color: #03a9f4; color: white" raised onclick="onFormSubmit()">Submit Changes</paper-button>
                </form>
            </iron-form>
         </div>

Script

<script>
        class IronListComponent extends Polymer.Element {
            static get is() {return 'iron-comp'}
        ready() {
                super.ready();
                var that = this;
            }
            pullupClose() {
                var element = $("#idSidePullup");
                console.log('console log of $("#idSidePullup") = ', element);
                $("#idSidePullup").addClass('hidePullup');
                $("#idSidePullup").css("display", "none");
            }
window.customElements.define(IronListComponent.is, IronListComponent);
    </script>

Answer №1

It is crucial to focus on the Polymer dom before proceeding.

let targetElement = $(Polymer.dom(this.root).querySelector('#idSidePullup'))
