這篇文章主要介紹了bootstrap treeview 樹形菜單帶復(fù)選框及級(jí)聯(lián)選擇功能,代碼超簡(jiǎn)單，感興趣的朋友跟隨腳本之家小編一起學(xué)習(xí)吧

具體代碼如下所示：

<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;
  }
  //選中全部父節(jié)點(diǎn) 
  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);
   }
  }
  //取消全部父節(jié)點(diǎn) 
  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; //是否全部沒(méi)選中 
   for (var i in siblings) {
    if (siblings[i].state.checked) {
     isAllUnchecked = false;
     break;
    }
   }
   if (isAllUnchecked) {
    uncheckAllParent(parentNode);
   }
  }
  //級(jí)聯(lián)選中所有子節(jié)點(diǎn) 
  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]);
    }
   }
  }
  //級(jí)聯(lián)取消所有子節(jié)點(diǎn) 
  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>
