ztree 官网的中的 例子中，所有菜单都是连着的，如果出现某个菜单下无子节点，那么在搜索时，此节点便不会自动展开，这里给出对应的增强版代码
我要评论
var setting = {
data: {
key: {
title: "t"
},
simpledata: {
enable: true
}
},
view: {
fontcss: getfontcss
}
};
var znodes =[
{ id:1, pid:0, name:"系统参数",open:true},
{ id:11, pid:1, name:"通用参数"},
{ id:111, pid:11, name:"状态a"},
{ id:112, pid:11, name:"状态b"},
{ id:12, pid:1, name:"日志"},
{ id:121, pid:12, name:"操作类型"},

];
var lastvalue = '', nodelist = [], fontcss = {};
function searchnode(e) {
var ztree = $.fn.ztree.getztreeobj("treedemo");
var value = $.trim(key.val());
lastvalue = value;
//ztree.expandall(true);
$('#treedemo').html("");
$.fn.ztree.init($("#treedemo"), setting, znodes);
if (value != "") {
nodelist = ztree.getnodesbyparamfuzzy("name", value);
} else {
nodelist = ztree.getnodesbyparamfuzzy("name", "|||||||||||||||");
}
updatenodes(true);
}
var parentnode = [];
function updatenodes(highlight) {
var ztree = $.fn.ztree.getztreeobj("treedemo");
parentnode = [];
for( var i=0, l=nodelist.length; i<l; i++) {
nodelist[i].highlight = highlight;
ztree.updatenode(nodelist[i]);
if (!nodelist[i].isparent && !parentnode.contains(nodelist[i].getparentnode().pid)) {
ztree.expandnode(nodelist[i].getparentnode(), true, true, true);
parentnode.push(nodelist[i].getparentnode().pid);
console.log(nodelist[i].getparentnode().pid);
} else {
ztree.expandnode(nodelist[i], true, true, true);
}
}
console.log(parentnode);
}
array.prototype.contains = function (obj) {
var i = this.length;
while (i--) {
if (this[i] === obj) {
return true;
}
}
return false;
}
function getfontcss(treeid, treenode) {
return (!!treenode.highlight) ? {color:"#a60000", "font-weight":"bold"} : {color:"#333", "font-weight":"normal"};
}
var key;
$(document).ready(function(){
$.fn.ztree.init($("#treedemo"), setting, znodes);
key = $("#search_name");
key.bind("blur", searchnode);
});
效果图
以上所述是小编给大家介绍的ztree搜索中多级菜单展示不全的解决方法，希望对大家有所帮助
