试图在jstree中的change_state上获取已检查项目的列表 [英] Trying to get a list of checked items on change_state in jstree
问题描述
使用 jsTree (pre1.0_fix_1),我想获取所有已检查项目的 id
列表(或更好) ,一个带有 id
的JSON对象和每个已检查项目的文本。然后我会用这个做一个ajax调用。此外,这应该在任何时候进行状态更改时检查或取消选中。
Using jsTree (pre1.0_fix_1), I would like to obtain a list of id
's for all the checked items (or better, a JSON object with id
AND text of each checked item). I will then make an ajax call with this. Additionally, this should happen any time there is a state change of something getting checked or unchecked.
这是我目前所拥有的:
$(function(){
n = $('#colors').jstree({
"plugins": ["themes", "html_data", "checkbox"]
}).bind("change_state.jstree", function(e, data){
console.log($('#colors').jstree('get_selected').attr('id'));
});
});
这只是从容器的<$ c返回' colors ' $ c> id :< div id =colors>
。我在数据
对象附近钓鱼,但没有在那里找到它(也许我错过了它?)
This is just returning 'colors', from the container'sid
: <div id="colors">
. I fished around the data
object, but didn't find it in there (perhaps I missed it?)
推荐答案
为了获得已检查节点的JSON,你应该使用 get_checked
而不是 get_selected
。试试这个:
In order to get the checked nodes' JSON you should be using get_checked
and not get_selected
. Try this:
var checked = $("#colors").jstree("get_checked",null,true);
var checked_json = [];
$(checked).each(function (i,node) {
var id = $(node).attr("id");
var text = $(node).attr("text");
var node_json = {
"id" : id,
"text" : text
};
checked_json.push(node_json);
});
之后 checked_json
将包含一个数组您可以发送到服务器的id +文本对象。
After that checked_json
will contain an array of of id+text objects which you could send to the server.
