我可以使用替代 JSON 格式创建 jstree,如下所示:
$('#using_json_2').jstree({ 'core' : {
'data' : [
{ "id" : "ajson1", "parent" : "#", "text" : "Simple root node" },
{ "id" : "ajson2", "parent" : "#", "text" : "Root node 2" },
{ "id" : "ajson3", "parent" : "ajson2", "text" : "Child 1" },
{ "id" : "ajson4", "parent" : "ajson2", "text" : "Child 2" },
]
} });
但它是相当静态的。我希望它是动态的;从某种意义上说,行数可以是可变的,行属性可以从数组中读取。我不想使用 ajax,因为数据已经在数组中可用。
最佳答案
如果你希望你的数据是动态的,你可以使用下面的代码来初始化你的jstree:
$('#jstree').jstree({
'core': {
'data': arrayCollection
}
});
其中arrayCollection是一个包含动态数组的变量。例如,您的 arrayCollection 可能如下所示:
var arrayCollection = [
{"id": "animal", "parent": "#", "text": "Animals"},
{"id": "device", "parent": "#", "text": "Devices"},
{"id": "dog", "parent": "animal", "text": "Dogs"},
{"id": "lion", "parent": "animal", "text": "Lions"},
{"id": "mobile", "parent": "device", "text": "Mobile Phones"},
{"id": "lappy", "parent": "device", "text": "Laptops"},
{"id": "daburman", "parent": "dog", "text": "Dabur Man", "icon": "/"},
{"id": "Dalmation", "parent": "dog", "text": "Dalmatian", "icon": "/"},
{"id": "african", "parent": "lion", "text": "African Lion", "icon": "/"},
{"id": "indian", "parent": "lion", "text": "Indian Lion", "icon": "/"},
{"id": "apple", "parent": "mobile", "text": "Apple IPhone 6", "icon": "/"},
{"id": "samsung", "parent": "mobile", "text": "Samsung Note II", "icon": "/"},
{"id": "lenevo", "parent": "lappy", "text": "Lenevo", "icon": "/"},
{"id": "hp", "parent": "lappy", "text": "HP", "icon": "/"}
];
最后,您的 html 文件应如下所示:
<html>
<head>
<title>JSTree</title>
<link rel="stylesheet" href="dist/themes/default/style.css" />
<script src="dist/libs/jquery.js"></script>
<script src="dist/jstree.js"></script>
<script>
$(function() {
var arrayCollection = [
{"id": "animal", "parent": "#", "text": "Animals"},
{"id": "device", "parent": "#", "text": "Devices"},
{"id": "dog", "parent": "animal", "text": "Dogs"},
{"id": "lion", "parent": "animal", "text": "Lions"},
{"id": "mobile", "parent": "device", "text": "Mobile Phones"},
{"id": "lappy", "parent": "device", "text": "Laptops"},
{"id": "daburman", "parent": "dog", "text": "Dabur Man", "icon": "/"},
{"id": "Dalmation", "parent": "dog", "text": "Dalmatian", "icon": "/"},
{"id": "african", "parent": "lion", "text": "African Lion", "icon": "/"},
{"id": "indian", "parent": "lion", "text": "Indian Lion", "icon": "/"},
{"id": "apple", "parent": "mobile", "text": "Apple IPhone 6", "icon": "/"},
{"id": "samsung", "parent": "mobile", "text": "Samsung Note II", "icon": "/"},
{"id": "lenevo", "parent": "lappy", "text": "Lenevo", "icon": "/"},
{"id": "hp", "parent": "lappy", "text": "HP", "icon": "/"}
];
$('#jstree').jstree({
'core': {
'data': arrayCollection
}
});
});
</script>
</head>
<body>
<div id="jstree"></div>
</body>
</html>
每当您的 arrayCollection 被修改时,您都必须将 arrayCollection 重新分配给您的 jstree 并以编程方式刷新 jstree。
