单击模式上的“取消”按钮后文档重新加载[重复]

Question

我正在使用 HTML、引导程序 CSS 和 Jquery 构建一个项目。 这是我的 HTML 代码：

</body>

</html>

这是 CSS 代码：

body{
    font-family: 'Exo', sans-serif;
}

.main{
    background-color:rgb(4, 209, 4);
    margin:30px;    
    border-radius:10px;
    padding-top: 0px;
    padding-bottom:20px;
}

.navbar{
    background-color:white;
    padding-left:0px;
    padding-right:0px;
    margin-left:auto;
    margin-right:auto;
    padding:0px;
}

.nav-link{
    color:black;
}

li{
    font-size:25px;
    text-align:center;
}

li.active{
    background-color: rgb(4, 209, 4);
    color:black;
    border:5px double;
    border-bottom:none;
}

li.inactive{
    background-color: green;
    
}

.box{
    border:1px solid rgb(92, 86, 86);
    border-radius:10px;
    padding:20px;
}

.overview{
    background-color: white;
    padding:5px;
    justify-content:center;
    border-radius:50px;
    text-align:center;
}

#tarwebs{
    background-color: rgb(128, 183, 231);
    padding:10px;
    justify-content:center;
    border-radius:50px;
}

.targets{
    background-color: white;
    height: 40px;
    border-radius:25px;
    padding:8px 30px 8px 15px;

}

.target-input{
    background-color: antiquewhite;
    border-radius:2px;
}

.fa-star:hover{
    color:rgb(241, 241, 214);
}

.select{
    color:yellow;
}

.deselect{
    color:black;
}

这是 Javascript(Jquery) 代码：

$(document).ready(function () {
    $("#firstul li").on("click", function () {
        $("#firstul li").removeClass("active").addClass("inactive");
        $(this).removeClass("inactive").addClass("active");
        $(".tab-pane").removeClass("active show").addClass("d-none");
        let value = this.children[0].getAttribute("href");
        $(value).addClass("active show").removeClass("d-none");
    });
    $("#addbtn").on("click", function () {
        $("#myModal").modal("show");
    });
    $("#close").on("click", function () {
        $("#myModal").modal("hide");
    });

    $("#targeturl").on("input change", function () {
        if ($("this").val() == "")
            $("#submit").prop("disabled", true);
        else
            $("#submit").prop("disabled", false);
    });


    $(".fa-star").on("click", function () {
        $(this).toggleClass("select deselect");
    });

    $("#submit").on("click", function (e) {
        e.preventDefault();
        $("#myModal").modal("hide");
        let url = $("#targeturl").val();
        let name = $("#targetname").val();
        let domain = new URL(url);
        domain = domain.hostname;
        if (name == "") {
            name = domain;
        }
        let text = `<div class="targets" style="margin-down:10px;"><img src="https://s2.googleusercontent.com/s2/favicons?domain_url=${domain}"><b style="margin-left:10px;">${name}</b><i class="fa fa-trash" style="font-size:25px;float:right;" type="button"></i><i class="fa fa-star select" style="font-size:25px;float:right;margin-right: 10px;" type="button"></i></div>`;

        document.getElementById("tarwebs").innerHTML+=text;

    })

});

我的问题是：

输入modal中指定的表单并提交后，文档按预期变化（出现一个div元素如预期）。 但是再次打开模式后（通过单击下面的加号图标），如果我单击“取消”按钮而不输入任何详细信息，则页面重新加载并且文档中所有以前的 div 元素都消失了。 我希望用户应该保留以前的 div 元素，并通过再次填充模态来添加另一个 div 元素。
第二次重新打开模态后，保留以前的输入。 我必须先删除这些输入，然后再填充另一个。

如果有人能解决这些问题，我会很高兴。

Answer 1

 $(document).ready(function(event) { $(#button-cancel).on('click', '#my-modal', function() { // do your things event.preventDefault(); return false; }); });
