我想在vue js中使用HTML5拖放.

我看到了关于拖放的w3schools教程.

我的教程代码和链接是:

我在vue js的方法范围中定义了所有方法.

推荐答案

例如，您只需要调用vue事件，而不是html事件v-on:drop，而不是drop

下面是您在与vue的链接中提供的示例的实现

 <html>
      <head>
        <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
        <style>
        .droptarget {
      float: left; 
      width: 100px; 
      height: 35px;
      margin: 15px;
      padding: 10px;
      border: 1px solid #aaaaaa;
    }
    </style>
        </style>
      </head>
      <body>
        <div id="app">
          <p>Drag the p element back and forth between the two rectangles:</p>
          <div
            class="droptarget"
            v-on:drop="drop"
            v-on:dragover="allowDrop"
          >
            <p
            v-on:dragstart="dragStart"
              v-on:drag="dragging"
              draggable="true"
              id="dragtarget"
            >
              Drag me!
            </p>
          </div>
    
          <div
            class="droptarget"
            v-on:drop="drop"
            v-on:dragover="allowDrop"
          ></div>
    
          <p style="clear:both;">
            <strong>Note:</strong> drag events are not supported in Internet
            Explorer 8 and earlier versions or Safari 5.1 and earlier versions.
          </p>
    
          <p id="demo"></p>
        </div>
        <script>
          var app = new Vue({
            el: "#app",
           
            methods: {
              dragStart:function(event)  {
                event.dataTransfer.setData("Text", event.target.id);
              },
              dragging:function(event) {
                document.getElementById("demo").innerHTML =
                  "The p element is being dragged";
              },
              allowDrop:function(event) {
                event.preventDefault();
              },
              drop:function(event) {
                event.preventDefault();
                var data = event.dataTransfer.getData("Text");
                event.target.appendChild(document.getElementById(data));
                document.getElementById("demo").innerHTML =
                  "The p element was dropped";
              }
    
            }
          });
        </script>
      </body>
    </html>
