我怎样才能改变树的颜色?

How can I change the tree's color?

嗯,我"created"一棵小树有两个parents和三个children使用JqTree,现在我想改变它的属性,比如如颜色、边框等,但我不想更改库。你能帮帮我吗?

提前致谢。

var ExampleData = {};

ExampleData.data = [{
  label: 'node1',
  id: 1,
  children: [{
    label: 'child1',
    id: 2
  }, {
    label: 'child2',
    id: 3
  }]
}, {
  label: 'node2',
  id: 4,
  children: [{
    label: 'child3',
    id: 5
  }]
}];

ExampleData.getFirstLevelData = function(nodes) {
  if (!nodes) {
    nodes = ExampleData.example_data;
  }

  var data = [];

  $.each(nodes, function() {
    var node = {
      label: this.label,
      id: this.id
    };

    if (this.children) {
      node.load_on_demand = true;
    }

    data.push(node);
  });

  return data;
}

ExampleData.getChildrenOfNode = function(node_id) {
  var result = null;

  function iterate(nodes) {
    $.each(nodes, function() {
      if (result) {
        return;
      } else {
        if (this.id == node_id) {
          result = this;
        }

        if (this.children) {
          iterate(this.children);
        }
      }
    });
  }

  iterate(ExampleData.example_data);

  return ExampleData.getFirstLevelData(result.children);
}

$('#tree1').tree({
  data: ExampleData.data,
  autoOpen: false,
  dragAndDrop: true

});
  #navdata {

    width: auto;

    height: auto;

    flex: 1;

    padding-bottom: 1px;

  }

  #navgrid {

    width: 50%;

    height: 200px;

    overflow-x: visible;

    overflow-y: scroll;

    border: solid 1px #79B7E7;

    background-color: #DDEBF7;

  }

  #header {

    background-color: #79B7E7;

    width: 100%;

    text-align: center;

    border: 1px solid white;

  }

  #tree {

    background-color: #FF0000;

  }

感谢@risadinha 的正确搜索,与我所做的不同,至少答案现在会在 Whosebug 上。

var data = [
  {
    label: 'node1',
    id: 1,
    color: 'green'
  }
];

在 CSS 上:

.jqtree-element {
  background-color: red;
}

为 jqTree 添加以下 css

1 级:

.jqtree-tree .jqtree-title .jqtree-title-folder {
    color: aqua !important;
}

2级:

.jqtree-tree .jqtree-title {
    color: bisque !important;
}
