[JS] 로딩 (로드시 이벤트 설정하기)

7ingout 2022. 6. 13. 15:53

방법 3가지 !

1. window.onload = function() {

실행문

}

2. <body onload="loadingFunc()">

function loadingFunc() {

실행문

}

</script>

3.window.addEventListener("load", function() {

실행문

})

* 인터넷 속도 넘 빨라서 window.onload = hideLoading; 대신 이렇게도 씀

function hideLoading() {

let spinner = document.querySelector('#spinnerwrap');
spinner.style.display = "none";
}

setTimeout(() => {
// alert("로딩끝");
hideLoading();
}, 2000);

html 블럭

<div id="spinnerwrap">
    <div class="spinner">
        <div class="bounce1"></div>
        <div class="bounce2"></div>
        <div class="bounce3"></div>
    </div>
</div>

script 블럭

<script>
    // window.onload = function() {
    //     alert("로딩끝");
    // }

    function hideLoading() {
        let spinner = document.querySelector('#spinnerwrap');
        spinner.style.display = "none";
    }

    // setTimeout(() => {
    //     // alert("로딩끝");
    //     hideLoading();
    // }, 2000);

    window.onload = hideLoading;
</script>
