#GWC UI Library : Accordion

웹 UI 라이브러리인 GWC에서 제공하는 Accordion 컴포넌트에 대한 예제 코드입니다.

먼저 DOM 구성은 다음과 같습니다.

<div class="center">
    <gwc-label id="label" content="Accordion 이벤트"></gwc-label>
    <gwc-accordion id="accordion">
        <parts>
            <part title="툴버튼" count=32 icon="./images/icon1.png" open=true>
                <div class="part1">
                    <gwc-toolbutton icon="images/icon2.png"></gwc-toolbutton>
                    <gwc-toolbutton icon="images/icon3.png"></gwc-toolbutton>
                    <gwc-toolbutton icon="images/icon1.png"></gwc-toolbutton>                            
                </div>
            </part>
            <part title="메세지" count=0>
                <div class="part2">
                    <div class="part2-sub">
                        <gwc-checkbox title="사과"></gwc-checkbox>
                        <gwc-checkbox title="토마토"></gwc-checkbox>
                        <gwc-checkbox title="귤"></gwc-checkbox>
                        <gwc-checkbox title="당근"></gwc-checkbox>
                        <gwc-checkbox title="바나나"></gwc-checkbox>
                    </div>
                    <gwc-slider label="볼륨" unit="dB" to-fixed=1 min=0 max=100 value=45></gwc-slider>
                </div>
            </part>
            <part title="설정" icon="./images/icon2.png">
                <div class="part3">
                    <gwc-radiogroup>
                        <items>
                            <item>CSS</item>
                            <item>JS</item>
                            <item>HTML</item>
                        </items>
                    </gwc-radiogroup>
                    <div>
                        <gwc-label content="진행율" outline-type="concave"></gwc-label>
                        <gwc-progress auto="true"></gwc-progress>
                    </div>
                </div>
            </part>                                        
        </parts>
    </gwc-accordion>

    <gwc-button id="button" title="2번째 열기/닫기"></gwc-button>
</div>

그리고 CSS 구성은 다음과 같구요.

.center {
    display: flex;
    width: 100%;
    height: 100%;
    justify-content: center;
    align-items: center;
    flex-direction: column;
    gap: 1em;
}

.part1 {
    display: flex;
    width: 100%;
    height: 8em;
    justify-content: center;
    align-items: center;
    flex-wrap: wrap;
    gap: 1em;
}

.part2 {
    display: flex;
    width: 100%;
    height: 13em;
    justify-content: center;
    align-items: center;
    flex-wrap: wrap;
    flex-direction: column;
    gap: 1em;
}

.part2-sub {
    display: flex;
    width: 100%;
    height: 7em;
    justify-content: center;
    align-items: center;
    flex-wrap: wrap;
    _gap: 1em;
}

.part3 {
    display: flex;
    width: 100%;
    height: 8em;
    justify-content: center;
    align-items: center;
    flex-wrap: wrap;
    _gap: 1em;
}

.vcenter {
    display: flex;
    width: 100%;
    height: 100%;
    justify-content: center;
    align-items: center;
    flex-direction: column;
    gap: 1em;
}

#accordion {
    width: 20em;
}

gwc-vscrollview {
    width: 90%;
    height: 90%;
}

p:nth-child(2n) {
    color: greenyellow;
    font-size: 0.9em;
}

p:nth-child(2n+1) {
    color: yellow;
}

gwc-progress {
    width: 9em
}

js 코드는 다음과 같습니다.

window.onload = () => {
    setInterval(() => {
        const count = accordion.getCount(2);
        accordion.setCount(2, count+1);
    }, 100);

    button.onclick = () => {
        if(accordion.isClosed(2)) accordion.open(2);
        else accordion.close(2);
    }

    accordion.addEventListener("change", (event) => {
        label.content = `${event.detail.partIndex}번째가 
            ${event.detail.state === "opened" ? "열렸습니다." : "닫혔습니다."}`;
    });

    GeoServiceWebComponentManager.instance.update();
};

실행 결과는 다음과 같습니다.
