我正在尝试使用FuelUX实现树视图。
到目前为止，我设法从网站上设置了示例：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

</head>
<body class="fuelux">
<ul class="tree fuelux" role="tree" id="myTree">
<li class="tree-branch hide" data-template="treebranch" role="treeitem" aria-expanded="false">
<div class="tree-branch-header">
<button class="tree-branch-name">
<span class="glyphicon icon-caret glyphicon-play"></span>
<span class="glyphicon icon-folder glyphicon-folder-close"></span>
<span class="tree-label"></span>
</button>
</div>
<ul class="tree-branch-children" role="group"></ul>
<div class="tree-loader" role="alert">Loading...</div>
</li>
<li class="tree-item hide" data-template="treeitem" role="treeitem">
<button class="tree-item-name">
<span class="glyphicon icon-item fueluxicon-bullet"></span>
<span class="tree-label"></span>
</button>
</li>
</ul>

if ("type" in options && options.type == "folder") {
if ("dataAttributes" in options && "children" in options.dataAttributes) {
param = options.dataAttributes["id"];
}
}
if (param != null) {
$.ajax({

error: function (response) {
console.log(response);
}
})
}
setTimeout(function () {
callback({ data: [
{ name: 'Ascending and Descending', type: 'folder', dataAttributes: { id: 'folder1' } },
{ name: 'Sky and Water I (with custom icon)', type: 'item', dataAttributes: { id: 'item1', 'data-icon': 'glyphicon glyphicon-file' } },
{ name: 'Drawing Hands', type: 'folder', dataAttributes: { id: 'folder2' } },
{ name: 'Waterfall', type: 'item', dataAttributes: { id: 'item2' } },
{ name: 'Belvedere', type: 'folder', dataAttributes: { id: 'folder3' } },
{ name: 'Relativity (with custom icon)', type: 'item', dataAttributes: { id: 'item3', 'data-icon': 'glyphicon glyphicon-picture' } },
{ name: 'House of Stairs', type: 'folder', dataAttributes: { id: 'folder4' } },
{ name: 'Convex and Concave', type: 'item', dataAttributes: { id: 'item4' } }
]});
}, 400);
},
multiSelect: true,
cacheItems: true,
folderSelect: false,
});
});
</script>
</body>
</html>
不幸的是，在“ dataSource”中传递的
options参数没有属性（type，dataAttributes等）。我究竟做错了什么？如何设置这些参数？
谢谢
最佳答案
我得到的是options.type的"folder"。至于options.children，它不会出现在项目/文件夹的回调数据对象中。
这对我有用：
$('#myTree1').tree({
dataSource: function(options, callback){
var self = this;
var param = null
console.log(options.type);
if ("type" in options && options.type == "folder") {
if ("dataAttributes" in options && "children" in options.dataAttributes) {
param = options.dataAttributes["id"];
}
}
if (param != null) {
$.ajax({
url: "@routes.FileController.getFolderStructure()",
data: 'id=' + param,
type: 'POST',
dataType: 'json',
success: function (response) {
callback(response)
},
error: function (response) {
console.log(response);
}
})
}
setTimeout(function () {
callback({ data: [
{ name: 'Ascending and Descending', type: 'folder', dataAttributes: { id: 'folder1' } },
{ name: 'Sky and Water I (with custom icon)', type: 'item', dataAttributes: { id: 'item1', 'data-icon': 'glyphicon glyphicon-file' } },
{ name: 'Drawing Hands', type: 'folder', dataAttributes: { id: 'folder2' } },
{ name: 'Waterfall', type: 'item', dataAttributes: { id: 'item2' } },
{ name: 'Belvedere', type: 'folder', dataAttributes: { id: 'folder3' } },
{ name: 'Relativity (with custom icon)', type: 'item', dataAttributes: { id: 'item3', 'data-icon': 'glyphicon glyphicon-picture' } },
{ name: 'House of Stairs', type: 'folder', dataAttributes: { id: 'folder4' } },
{ name: 'Convex and Concave', type: 'item', dataAttributes: { id: 'item4' } }
]});
}, 400);
},
multiSelect: true,
cacheItems: true,
folderSelect: false,
});
我所做的就是将以上内容复制到Fuel UX存储库中的index.js中，并添加
condole.log。打开“ Ascending and Descending”（升序和降序）（该项目的类型）时，它将输出“文件夹”。关于javascript - FuelUX Tree数据源选项未定义，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/26179456/
