基于jstree使用AJAX请求获取数据形成树
时间：2022-01-06 09:20:16|栏目：JavaScript代码|点击： 次
概述：
一般情况下都是通过ajax进行请求获取数据。boostrap+ajax
1、代码
//权限分配
$('#authority').click(function() {
$("#jstree").jstree({
"core" : {
"themes" : {
"responsive": false
},
// so that create works
"check_callback" : true,
'data' : function (obj, callback) {
var jsonstr="[]";
var jsonarray = eval('('+jsonstr+')');
$.ajax({
type: "GET",
url:"/demo/authority/getAuthoritys",
dataType:"json",
async: false,
success:function(result) {
var arrays= result;
for(var i=0 ; i<arrays.length; i++){
console.log(arrays[i])
var arr = {
"id":arrays[i].id,
"parent":arrays[i].parentId=="root"?"#":arrays[i].parentId,
"text":arrays[i].name
}
jsonarray.push(arr);
}
}
});
callback.call(this, jsonarray);
}
},
"types" : {
"default" : {
"icon" : "glyphicon glyphicon-flash"
},
"file" : {
"icon" : "glyphicon glyphicon-ok"
}
},
"state" : { "key" : "demo2" },
"plugins" : [ "dnd", "state", "types","checkbox","wholerow" ]
});
$('#setAuthority').modal();
});
总结：
"responsive": false ：表示主题是否适应手机类小尺寸屏幕，默认为false
"check_callback" : true：表示形成树是否可以重新组织，也是改变顺序，层次关系
callback.call(this, jsonarray)：将数组放入树形
types:{}设置类型，图标
"state" : { "key" : "demo2" }：将选中的状态保存浏览器中
"plugins" : [ "dnd", "state", "types","checkbox","wholerow" ] 表示插件相关，详情参考点击打开链接
url路径换成你后台地址，返回时json数组
2、html标签
<!-- 权限分配模框-->
<div class="modal fade" id="setAuthority">
<div class="modal-dialog">
<div class="modal-content message_align">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"
aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title">权限分配</h4>
</div>
<div class="modal-body">
<div id= "jstree">
</div>
</div>
<div class="modal-footer">
<input type="hidden" id="url" />
<button type="button" class="btn btn-default" data-dismiss="modal">取消</button>
<a onclick="authorityConfirm()" class="btn btn-success"
data-dismiss="modal">确定</a>
</div>
</div>
<!-- /.modal-content -->
</div>
<!-- /.modal-dialog -->
</div>
