onclick事件在WEB页面上不起作用

我想创建一个模态框。当用户单击按钮时,它应该出现,并在用户单击模式框中的关闭按钮时关闭。 我做了两个功能:

  • check():它改变了css。在它的elememt onclick之后,出现模式框
  • close():这个函数应该关闭模态框,但它不是。它应该只设置以前的CSS设置。单击关闭按钮(span元素)时,此功能根本不执行。

为什么关闭功能不起作用以及我应该现代化以获得结果?

function check() {
    var modal = document.getElementById("myModal");
    modal.style.display = "block";
}
//this function dont't work
function close(){
    var modal = document.getElementById("myModal");
    modal.style.display = "none";
}
.modal {
    display: none;
    position: fixed;
    z-index: 1;
    padding-top: 100px;
    left: 0;
    top: 0;
    width: 100%; 
    height: 100%;
    overflow: auto;
    background-color: rgb(0,0,0);
    background-color: rgba(0,0,0,0.4);
}


.modal-content {
    background-color: #fefefe;
    margin: auto;
    padding: 20px;
    border: 1px solid #888;
    width: 80%;
}

window.close()已经是本机浏览器功能function check() { var modal = document.getElementById("myModal"); modal.style.display = "block"; } function closeModal(){ var modal = document.getElementById("myModal"); modal.style.display = "none"; }的名称。重命名你的功能,它工作正常:

.modal {
    display: none;
    position: fixed;
    z-index: 1;
    padding-top: 100px;
    left: 0;
    top: 0;
    width: 100%; 
    height: 100%;
    overflow: auto;
    background-color: rgb(0,0,0);
    background-color: rgba(0,0,0,0.4);
}


.modal-content {
    background-color: #fefefe;
    margin: auto;
    padding: 20px;
    border: 1px solid #888;
    width: 80%;
}
