如何在jstree中获取叶子节点，以便在使用jstree ui时单击时打开它们的超链接 [英] How to get I get leaf nodes in jstree to open their hyperlink when clicked when using jstree ui
问题描述
我使用jtree显示层次结构，数据如下
I display a hierachial structure using jtree, the data is as follows
<div id="songchanges"><ul>
<li id="phtml_1">
<a href="#">C:</a>
<ul>
<li id="phtml_2">
<a href="#">Music</a>
<ul>
<li id="phtml_3">
<a href="#">Z</a>
<ul>
<li id="phtml_4">
<a href="#">Hans Zimmer</a>
<ul>
<li id="phtml_5"><a href="FixSongsReport_00107_2013-09-04-11-11-55_body_blqxgT7E7YOmnBbjFXQGUg==.html">C:\Music\Z\Hans Zimmer\Hannibal</a></li>
</ul>
</li>
<li id="phtml_6">
<a href="#">The Zombies</a>
<ul>
<li id="phtml_7"><a href="FixSongsReport_00107_2013-09-04-11-11-55_body_er7mjWKbAaYaf8DygP84Fg==.html">C:\Music\Z\The Zombies\Best of The Zombies</a></li>
<li id="phtml_8"><a href="FixSongsReport_00107_2013-09-04-11-11-55_body_56XgVDhsjEKWXFd4OzVldA==.html">C:\Music\Z\The Zombies\The Zombies featuring Colin Blunstone & Rod Argent</a></li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
它显示为文件系统。
这是框架集的一部分，显示在屏幕的左侧，当用户点击叶子节点时，我希望它打开右侧的附加链接handside（就像我在应用jtree之前所做的那样）
This is the part of a frameset and is displayed on the left handside of the screen and when user clicks on leaf node I want it to open the attached link on the right handside (as it does before i applied jtree stuff to it)
我的jtree配置如下
My jtree configuration is as follows
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<link rel="stylesheet" type="text/css" href="songkong.css">
<base target="main">
<script type="text/javascript" src="http://static.jstree.com/v.1.0pre/jquery.js"></script>
<script type="text/javascript" src="http://static.jstree.com/v.1.0pre/jquery.cookie.js"></script>
<script type="text/javascript" src="http://static.jstree.com/v.1.0pre/jquery.hotkeys.js"></script>
<script type="text/javascript" src="http://static.jstree.com/v.1.0pre/jquery.jstree.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css" />
<script type="text/javascript" class="source below">
$(function () {
$("#songchanges")
.jstree({
"plugins" : ["themes","html_data","ui","crrm","hotkeys"],
"core" : { "initially_open" : [ "phtml_1" ] }
})
.bind("loaded.jstree", function (event, data) {
});
$("#songchanges").bind("open_node.jstree", function (e, data) {
data.inst.select_node("#phtml_1", true);
});
});
</script></head>
我读了demo3示例
$(function () {
$("#demo3")
.jstree({ "plugins" : ["themes","html_data","ui"] })
// 1) if using the UI plugin bind to select_node
.bind("select_node.jstree", function (event, data) {
// `data.rslt.obj` is the jquery extended node that was clicked
alert(data.rslt.obj.attr("id"));
})
// 2) if not using the UI plugin - the Anchor tags work as expected
// so if the anchor has a HREF attirbute - the page will be changed
// you can actually prevent the default, etc (normal jquery usage)
.delegate("a", "click", function (event, data) { event.preventDefault(); })
});
并尝试了但是.delegate选项没有效果，我假设我必须删除ui插件，但尝试我的页面看起来像我从来没有应用jstree。
and tried it but the .delegate option had no effect , I assume i have to remove"ui" plugin but trying that my page just looks like Ive never applied jstree.
绑定选项有点工作，因为它显示一个恼人的警报窗口显示每次我的ID单击任何节点。那么如何更改它以在右手边打开链接呢？
The bind option sort of worked, in that it displays an annoying alert window displaying the id every time i click on any node. So how can I change it to open the link in the right handside instead ?
更新
发现此答案当使用ui插件时，Jstree节点不起作用
添加
.bind("select_node.jstree", function (e, data) {
var href = data.rslt.obj.children("a").attr("href");
// this will load content into a div:
$("#contents").load(href);
// this will follow the link:
document.location.href = href;
})
现在链接在点击时打开，不幸的是它用页面替换了左边框架，而我希望它将它放入右边的窗格，任何想法。
Now the link is opened when clicked on, unfortunately it replaces the lefthandside frame with the page, whereas I want it put it into the right hand pane, any ideas.
推荐答案
新版本;
$("#demo2").jstree().bind("select_node.jstree", function (e, data) {
var href = data.node.a_attr.href;
document.location.href = href;
});
