Question

我看到了这个example，其中整个项目是可拖动的。我尝试更改拖动以仅在用户悬停时单击并仅单击文本，但它不起作用：

有人知道怎么做吗？

$scope.sortableOptions = {
  update: ..
},
  stop: ..
},
  handle: '.handle'
};

这里我的整个代码是。

<ul class="list logList">
  <li ng-repeat="entry in sortingLog track by $index" class="logItem">
    <span class="handle"> {{entry}} </span>
  </li>
</ul>

＆＃13;

var myapp = angular.module('sortableApp', ['ui.sortable']);


myapp.controller('sortableController', function ($scope) {
  var tmpList = [];
  
  for (var i = 1; i <= 6; i++){
    tmpList.push({
      text: 'Item ' + i,
      value: i
    });
  }
  
  $scope.list = tmpList;
  
  
  $scope.sortingLog = [];
  
  $scope.sortableOptions = {
    update: function(e, ui) {
      var logEntry = tmpList.map(function(i){
        return i.value;
      }).join(', ');
      $scope.sortingLog.push('Update: ' + logEntry);
    },
    stop: function(e, ui) {
      // this callback has the changed model
      var logEntry = tmpList.map(function(i){
        return i.value;
      }).join(', ');
      $scope.sortingLog.push('Stop: ' + logEntry);
    },
    handle: '.handle'
  };
});

    $( "#sortable" ).disableSelection();
  } );
  </script>
<body>
<style>
  #sortable { list-style-type: none; margin: 0; padding: 0; width: 60%; }
  #sortable li { margin: 0 3px 3px 3px; padding: 0.4em; padding-left: 1.5em; font-size: 1.4em; height: 18px; }
  #sortable li span { position: absolute; margin-left: -1.3em; }
  </style> 
<ul id="sortable">
  <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 1</li>
  <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 2</li>
