这篇文章主要介绍了使用jQuery+EasyUI实现CheckBoxTree的级联选中特效的相关资料,需要的朋友可以参考下
需求：子结点选中，父节点随之选中，父节点取消，子节点随之取消
代码：

$(function () {

}
} else {
var childNode = $("#tt").tree('getChildren', node.target);
if (childNode.length > 0) {
for (var i = 0; i < childNode.length; i++) {
$("#tt").tree('uncheck', childNode.target);
}
}
}
}
});
});
function getChecked()
{
var arr = [];
var checkeds = $('#tt').tree('getChecked', 'checked');
for (var i = 0; i < checkeds.length; i++) {
arr.push(checkeds.id);
}
alert(arr.join(','));
}
</script>
</head>
<body>
<ul id="tt"></ul>
<input type="button" value="获取选中" onclick="getChecked()" />
</body>
</html>
