如何将数据关联到jstree中的节点? [英] How to associate a data to a node in jstree?
问题描述
$("#ifTree").jstree({
"plugins" : ["themes","html_data","ui","crrm"],
"themes" : {
"theme" : "apple",
"dots" : true,
"icons" : false
}
});
$("#createIf_c").click(function () {
$("#ifTree").jstree("create",null,"inside", { "data" :{ title:"if",value:"expression"} },
function() {}, true);
});
$("#display").click(function(){
var a = $.jstree._focused().get_selected();
alert(a.attr("value"));
});
在上面的代码中,我创建了一个jstree,并单击ID为#createIf_c的按钮,我添加了一个标题为"if"的节点,但是由于我希望有更多数据与此节点相关联,因此我添加了更多创建节点时对其赋予属性.接下来,当我尝试访问此关联数据(此处为值")时,我将收到警报未定义".那么,是否存在将数据与节点关联的其他方法? jstree是访问节点关联数据的另一种方法?请帮助....
In this above code I have created a jstree and upon click of a button with id #createIf_c I am adding a node with title "if" but as I want some more data to be associated with this node , I have added more attributes to it while creating the node. Next when I am trying to access this associated data, here "value" then I am getting the alert 'undefined'. So is there a different way for associating data with a node? or a different way of accessing the associated data of a node is jstree?..please help....
推荐答案
最简单的方法就像将属性添加到html元素即
The simplest way to do this is just like adding an attribute to an html element i.e.,
var node = $.jstree._focused().get_selected(); //get the selected node or which ever you want the data to be associated with
node.attr("expression","xyz"); //add an attribute (name,value) here, name-expression and value-xyz
