bootstrap treeview 树形菜单带复选框及级联选择功能


            具体代码如下所示：





<div id="searchTree"></div> 

 <script>

  var treeData = [{

   text: "Parent 1",

   nodes: [{

    text: "Child 1",

    nodes: [{

     text: "Grandchild 1"

    }, {

     text: "Grandchild 2",

     nodes: [{

      text: "Grandchild 2-1",

      nodes: [{

       text: "Grandchild 2-1-1"

      }, {

       text: "Grandchild 2-2-1",

      }]

     }, {

      text: "Grandchild 1-2",

     }]

    }]

   }, {

    text: "Child 2",

    nodes: [{

     text: "Grandchild 2-1"

    }, {

     text: "Grandchild 2-2",

    }]

   }]

  }, {

   text: "Parent 2",

   id:'11111'

  }, {

   text: "Parent 3"

  }, {

   text: "Parent 4"

  }, {

   text: "Parent 5"

  }];

  var nodeCheckedSilent = false;

  function nodeChecked(event, node) {

   if (nodeCheckedSilent) {

    return;

   }

   nodeCheckedSilent = true;

   checkAllParent(node);

   checkAllSon(node);

   nodeCheckedSilent = false;

  }

  var nodeUncheckedSilent = false;

  function nodeUnchecked(event, node) {

   if (nodeUncheckedSilent)

    return;

   nodeUncheckedSilent = true;

   uncheckAllParent(node);

   uncheckAllSon(node);

   nodeUncheckedSilent = false;

  }

  //选中全部父节点 

  function checkAllParent(node) {

   $('#searchTree').treeview('checkNode', node.nodeId, {

    silent: true

   });

   var parentNode = $('#searchTree').treeview('getParent', node.nodeId);

   if (!("nodeId" in parentNode)) {

    return;

   } else {

    checkAllParent(parentNode);

   }

  }

  //取消全部父节点 

  function uncheckAllParent(node) {

   $('#searchTree').treeview('uncheckNode', node.nodeId, {

    silent: true

   });

   var siblings = $('#searchTree').treeview('getSiblings', node.nodeId);

   var parentNode = $('#searchTree').treeview('getParent', node.nodeId);

   if (!("nodeId" in parentNode)) {

    return;

   }

   var isAllUnchecked = true; //是否全部没选中 

   for (var i in siblings) {

    if (siblings[i].state.checked) {

     isAllUnchecked = false;

     break;

    }

   }

   if (isAllUnchecked) {

    uncheckAllParent(parentNode);

   }

  }

  //级联选中所有子节点 

  function checkAllSon(node) {

   $('#searchTree').treeview('checkNode', node.nodeId, {

    silent: true

   });

   if (node.nodes != null && node.nodes.length > 0) {

    for (var i in node.nodes) {

     checkAllSon(node.nodes[i]);

    }

   }

  }

  //级联取消所有子节点 

  function uncheckAllSon(node) {

   $('#searchTree').treeview('uncheckNode', node.nodeId, {

    silent: true

   });

   if (node.nodes != null && node.nodes.length > 0) {

    for (var i in node.nodes) {

     uncheckAllSon(node.nodes[i]);

    }

   }

  }

  $('#searchTree').treeview({

   showCheckbox: true,

   data: treeData,

   onNodeChecked: nodeChecked,

   onNodeUnchecked: nodeUnchecked

  });

  </script>
