javascript - 点击特定类触发打开模态事件

Question

我该如何解决这个问题？我已经使用 PHP 来显示我数据库中的数据，但我没有预见到这个错误。当我单击编辑时，模态将出现但是，当我单击其他数据的编辑按钮时，模态将不会出现。我怎样才能解决这个问题？我想要的是当我点击编辑按钮模式时会出现。我希望你能帮助我，这已经困扰我好几天了。

编辑按钮。

请参阅模态。

这是我的代码:

PHP:

echo "<div class='col-3'>";
                        echo "<div class='card'>";
                        echo "<div class='row'>";
                        echo "<div class='col-2'>";
                        echo "<h6 class='card-title'>".$row['project_name']."</h6>";

                        echo "</div>";

脚本:

//Edit Project Modal
var modal_edit = document.getElementById('modal_2');
var btn_edit = document.getElementById("btn-edit");
var span_edit = document.getElementsByClassName("close_2")[0];

btn_edit.onclick = function() { 
    $(modal_edit).toggleClass("modal-show");
}

span_edit.onclick = function() {
    $(modal_edit).removeClass("modal-show");    
}

$(".btn-secondary").click(function() {
    $(modal_edit).removeClass("modal-show");
});

Answer 1

尝试这样的事情。

1. 向您的编辑按钮添加一个通用类，如 class="btnEdit other_classes"

2. 试试这段代码

   var modal_edit = document.getElementById('modal_2');
   var span_edit = document.getElementsByClassName("close_2")[0];
   
   // I assumed that your button is added dynamically
   $(document).on('click',".btnEdit",function(){
       $(modal_edit).toggleClass("modal-show");
   });
   
   span_edit.onclick = function() {
       $(modal_edit).removeClass("modal-show");    
   }
   
   $(".btn-secondary").click(function() {
       $(modal_edit).removeClass("modal-show");
   });
   

您的点击不适用于其他元素，因为您正在使用 id 为它们分配事件，但 id 必须是唯一的。我用两个具有相同 ID 的元素制作了示例 fiddle ，并尝试查看它们的区别..

$("#first").click(function(){
  alert("I was clicked");
});

div{
display:inline-block;
width:100px;
height:100px;
border:1px solid red;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="first">DIV</div>
<div id="first">DIV</div>

只有第一个有效..所以改用class..
