问题描述

我有工作引导树视图。我想在此添加一个功能。






解决方案

使用此 var slectedNodeId,hasSelect = false,nodeIdList = [] 三个全局变量然后喜欢下面的代码。希望这会对你有所帮助。

  onNodeExpanded:function(event,node){
$ .each(node.nodes) ,function(){
if((this.nodeId == slectedNodeId || nodeIdList.indexOf(this.nodeId)> -1)
&& hasSelect)
{
$('#treeview-selectable')。treeview('selectNode',
[this.nodeId,{silent:true}]);
}
});
},
onNodeCollapsed:function(event,node){
nodeIdList.push(node.nodeId);
$ .each(node.nodes,function(){
if(this.state.selected){
$('#treeview-selectable')。treeview('selectNode',
[nodeIdList [0],{silent:true}]);
hasSelect = true;
}
});
},
onNodeSelected:function(event,node){
slectedNodeId = node.nodeId;
nodeIdList = [];
hasSelect = false;

$(this).treeview('unselectNode',[node.nodeId,{silent:false}]);
},
onNodeUnselected:function(event,node){
$(this).treeview('selectNode',[node.nodeId,{silent:true}]);
}

更新小提琴:


I have working bootstrap tree view. I want add one feature in this.

https://github.com/jonmiles/bootstrap-treeview (plugin used)

Eg: onNodeCollapsed: if collapsed node's child/grandChild already selected. then current collpased node should be shown as selected node.

Then on expand of this same node. it should show its/last selected or child/grandChild node.

onNodeCollapsed: function(event, node) {
    $.each(node.nodes, function() {
      if (this.state.selected) {
        $('#treeview-selectable').treeview('selectNode', [node.nodeId, {
          silent: true
        }]);
        return;
      }
    });
  }
解决方案

Use this var slectedNodeId, hasSelect=false, nodeIdList=[] three global variable and then do like the code below. Hope this will help you.

onNodeExpanded:function(event, node){
      $.each(node.nodes, function(){
            if((this.nodeId==slectedNodeId || nodeIdList.indexOf(this.nodeId)>-1)
                && hasSelect)
            {
                 $('#treeview-selectable').treeview('selectNode',
                              [ this.nodeId, { silent: true } ]);
            }
      });
},
onNodeCollapsed:function(event, node){
       nodeIdList.push(node.nodeId);
       $.each(node.nodes, function(){
             if(this.state.selected){
                 $('#treeview-selectable').treeview('selectNode',
                                 [nodeIdList[0], { silent: true } ]);
                 hasSelect=true;
             }
       });
},
onNodeSelected: function (event, node) {
       slectedNodeId=node.nodeId;
       nodeIdList=[];
       hasSelect=false;

       $(this).treeview('unselectNode', [ node.nodeId, { silent: false } ]);
},
onNodeUnselected: function (event, node) {
       $(this).treeview('selectNode', [ node.nodeId, { silent: true } ]);
}
