Question

我在地图上有很多弹出窗口，需要进行销毁操作。我附加了事件处理程序来发送ajax调用来销毁操作。但它只需单击就会发送两个ajax调用，下面是我的代码

   $(document).on 'click', '#map .leaflet-popup-content #delete', ->
     if confirm('Are you sure?')
       $.ajax
        type: 'POST'
        url: 'incidents/' + incident_id
        dataType: 'script'
        data:
          _method: 'delete'
          id: incident_id
        success: ->
          successFunction

您需要在您的函数中添加event作为输入，然后在event .preventDefault() method上调用

$(document).on('click', function(event, '#map .leaflet-popup-content #delete'){
     event.preventDeafault();
     // your code
});

我真的不知道如何用coffeescript写它，也许是这样的？

 $(document).on 'click', '#map .leaflet-popup-content #delete', (event) ->
     event.preventDefault()
     if confirm('Are you sure?')
       $.ajax
        type: 'POST'
        url: 'incidents/' + incident_id
        dataType: 'script'
        data:
          _method: 'delete'
          id: incident_id
        success: ->
          successFunction
