要在jQuery Tree中實現(xiàn)節(jié)點的批量操作,您可以使用以下方法:
<script src="//code.jquery.com/jquery-3.6.0.min.js"></script>

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/jQueryTree/1.0.0/jquery.tree.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jQueryTree/1.0.0/jquery.tree.min.js"></script>
<div id="tree"></div>
$(function() {
$("#tree").tree({
url: "your-data-source-url", // 數(shù)據(jù)源URL,返回JSON格式的樹形結(jié)構(gòu)數(shù)據(jù)
onClick: function(node) {
// 點擊樹節(jié)點時的操作
},
onDblClick: function(node) {
// 雙擊樹節(jié)點時的操作
}
});
});
function batchOperations(operation, nodes) {
switch (operation) {
case "add":
addNodes(nodes);
break;
case "remove":
removeNodes(nodes);
break;
case "update":
updateNodes(nodes);
break;
default:
console.log("Invalid operation");
}
}
function addNodes(nodes) {
$("#tree").tree("append", {
parent: nodes[0].id, // 要添加子節(jié)點的父節(jié)點ID
data: nodes.map(function(node) {
return node.label; // 子節(jié)點數(shù)據(jù),可以是字符串或?qū)ο?/span>
})
});
}
function removeNodes(nodes) {
nodes.forEach(function(node) {
$("#tree").tree("remove", node.id);
});
}
function updateNodes(nodes) {
nodes.forEach(function(node) {
$("#tree").tree("update", node.id, node.label); // 假設(shè)服務器返回的數(shù)據(jù)中有l(wèi)abel字段用于更新節(jié)點文本
});
}
batchOperations
函數(shù)進行節(jié)點批量操作:// 示例:添加節(jié)點
var nodesToAdd = [
{ id: "parent1", label: "Parent 1" },
{ id: "child1", label: "Child 1" },
{ id: "child2", label: "Child 2" }
];
batchOperations("add", nodesToAdd);
// 示例:刪除節(jié)點
var nodesToRemove = [
{ id: "node1" },
{ id: "node2" }
];
batchOperations("remove", nodesToRemove);
// 示例:更新節(jié)點
var nodesToUpdate = [
{ id: "node3", label: "Updated Node 3" }
];
batchOperations("update", nodesToUpdate);
這樣,您就可以根據(jù)需求實現(xiàn)節(jié)點的批量添加、刪除和更新操作。
