Checking a checkbox node programmatically with jsTree
提问by Raj
In a tree built with jsTree, I have the text within the <a>tag sitting in a variable. I would like to checkthat node. How can I do so?
在用 jsTree 构建的树中，我将<a>标签内的文本放在一个变量中。我想检查那个节点。我该怎么做？
I am currently finding that node, using jQuery, and altering its class. However, this does not repair the parent node by making the parent undeterminedin its class. I tried doing $('.colors').jstree("checkbox_repair"), but that didn't seem to do anything.
我目前正在使用 jQuery 查找该节点并更改其类。但是，这不会通过使父节点在其类中不确定来修复父节点。我试着做$('.colors').jstree("checkbox_repair")，但这似乎没有做任何事情。
It would be great if someone could actually answer both those questions, since they are related to the same problem.
如果有人能够真正回答这两个问题，那就太好了，因为它们与同一个问题有关。

In js_tree there are .check_node ( node )and .uncheck_node ( node )functions, i think this is what you are asking for. Soe the documentation here: http://www.jstree.com/documentation/checkbox
在 js_tree 中有.check_node ( node )和.uncheck_node ( node )函数，我认为这就是你所要求的。Soe 文档在这里：http: //www.jstree.com/documentation/checkbox
This is an excerpt from the documentation in the link above, "how to perform an operation":
这是上面链接中文档的摘录，“如何执行操作”：
/* METHOD ONE */
jQuery("some-selector-to-container-node-here")
.jstree("operation_name" [, argument_1, argument_2, ...]);
/* METHOD TWO */
jQuery.jstree._reference(needle)
/* NEEDLE can be a DOM node or selector for the container or a node within the container */
.operation_name([ argument_1, argument_2, ...]);
So I think this syntax should work
所以我认为这种语法应该有效
$.jstree._reference(".colors").check_node('li#tree_3');
Also i am not sure you should be using a class to reference your tree. Probably use an ID to reference your tree, and then use this syntax:
此外，我不确定您是否应该使用类来引用您的树。可能使用 ID 来引用您的树，然后使用以下语法：
$.jstree._reference("#colors").check_node('li#tree_3');
//EDIT: Please keep in mind that the newest version of jsTree doesn't have a function called _reference anymore. It got renamed to reference (without the leading underscore). (Last checked 24/08/2015 15:45 by @mkli90) Link: https://www.jstree.com/api/#/?f=$.jstree.reference(needle)
//编辑：请记住，最新版本的 jsTree 不再有名为 _reference 的函数。它被重命名为引用（没有前导下划线）。（上次检查时间为 24/08/2015 15:45 by @mkli90）链接：https: //www.jstree.com/api/#/ ?f =$.jstree.reference(needle)

If you want to check jsTree nodes on load for example like this:
如果要在加载时检查 jsTree 节点，例如像这样：
$(document).ready(function()
{
$.jstree._reference('#menu').check_node('#pih2');
});
it does not work. For me works following:
这是行不通的。对我来说，工作如下：
$(function () {
$('#mainMenu1').bind('loaded.jstree', function(e, data){ //waiting for loading
$.jstree._reference('#menu').check_node('#pih2'); //check node with id pih2
$.jstree._reference('#menu').check_node('#pih6'); //check node with id pih6
});
});
I use jsTree 1.0-rc3 and JQuery 1.7.1. Aloe
我使用 jsTree 1.0-rc3 和 JQuery 1.7.1。芦荟
