jstree使用新的

Posted 2021-01-06 joer717

1.首先准备jstree树的dom元素

<p id="flowList_ul" class="flowList_ul"></p>

2.初始化jstree使用

$(‘#flowList_ul‘).data(‘jstree‘, false).empty();//清空

function getFlowLists(){
$("#flowList_ul").jstree({
"core" : {
"animation" : 0,
"check_callback" : true,
"themes" : {
"theme" : "classic",
"dots" : true,
"icons" : true,
"stripes" : true
},
‘data‘ : function (obj, callback) {//jstree 数据全部请求出来  不是懒加载的方式
var jsonstr="[]";
var jsonarray = eval(‘(‘+jsonstr+‘)‘);
$.ajax({
type: "GET",
url:root+"/flowchart/getAllCasFlowchart",
dataType:"json",
async: false,
data: {
},
success:function(data) {
if(data.isSuccess == 1){
var arrays= data.rootArray;
for(var i=0 ; i<arrays.length; i++){
console.log(arrays[i]);

var arr = {
"id":arrays[i].id,
"parent":arrays[i].parent=="root"?"#":arrays[i].parent,
"text":arrays[i].text,
"type":arrays[i].type,
"a_attr":arrays[i].a_attr 自定义属性放在这里
}
jsonarray.push(arr);
}
}else{
layer.msg(data.msg,{icon:5,time:1500});
}

}

});
callback.call(this, jsonarray);
}
},
"types" : { 根据types设置图标
"default" : {
"icon": "assets/tree/greyPoint.png"
},
