我正在使用 jquery.jstree 插件，唯一的问题是右键单击一个节点并重命名它后，会打开文本输入框让我输入新名称。然后我输入新名称，但文本输入的值没有改变，就像冻结一样。如果我按下回车按钮，它会将相同的文本发布到服务器，但我无法修改文本输入中的值。
我在 Firefox 和 chrome 上都重现了这个问题。js 控制台上没有警告或错误消息。
此外，当我专注于树时，其他输入也不起作用，例如选项卡按钮、ctrl+f5 等。
对这个问题有任何想法吗？
我的jstree代码如下：
$(function () {
$("#tree-container")
.bind("before.jstree", function (e, data) {
$("#alog").append(data.func + "<br />");
})
.jstree({
// List of active plugins
"plugins": [
"themes", "json_data", "ui", "crrm", "cookies", "dnd", "search", "types", "contextmenu"
],
// I usually configure the plugin that handles the data first
// This example uses JSON as it is most common
"json_data": {
// This tree is ajax enabled - as this is most common, and maybe a bit more complex
// All the options are almost the same as jQuery's AJAX (read the docs)
"ajax": {
// the URL to fetch the data
"url": "/backoffice/categorytree/getchildren",
// the `data` function is executed in the instance's scope
// the parameter is the node being loaded
// (may be -1, 0, or undefined when loading the root nodes)
"data": function (n) {
// the result is fed to the AJAX request `data` option
return {
"ParentCategoryId": n.attr ? n.attr("id").replace("node_", "") : 1
};
}
}
},
// Configuring the search plugin
"search": {
// As this has been a common question - async search
// Same as above - the `ajax` config option is actually jQuery's AJAX object
"ajax": {
"url": "/backoffice/categorytree/search",
// You get the search string as a parameter
"data": function (str) {
return {
"SearchString": str
};
}
}
},
// Using types - most of the time this is an overkill
// read the docs carefully to decide whether you need types
"types": {
// I set both options to -2, as I do not need depth and children count checking
// Those two checks may slow jstree a lot, so use only when needed
"max_depth": -2,
"max_children": -2,
// I want only `drive` nodes to be root nodes
// This will prevent moving or creating any other type as a root node
"valid_children": ["drive"],
"types": {
// The default type
"default": {
// I want this type to have no children (so only leaf nodes)
// In my case - those are files
"valid_children": "none",
// If we specify an icon for the default type it WILL OVERRIDE the theme icons
"icon": {
"image": "http://www.jstree.com/static/v.1.0pre/_demo/file.png"
}
},
// The `folder` type
"folder": {
// can have files and other folders inside of it, but NOT `drive` nodes
"valid_children": ["default", "folder"],
"icon": {

"drive": {

"valid_children": ["default", "folder"],
"icon": {
"image": "http://www.jstree.com/static/v.1.0pre/_demo/root.png"
},
// those prevent the functions with the same name to be used on `drive` nodes
// internally the `before` event is used
"start_drag": false,
"move_node": false,
"delete_node": false,
"remove": false
}
}
},
// UI & core - the nodes to initially select and open will be overwritten by the cookie plugin
// the UI plugin - it handles selecting/deselecting/hovering nodes
"ui": {
// this makes the node with ID node_4 selected onload
"initially_select": ["node_4"]
},
// the core plugin - not many options here
"core": {
// just open those two nodes up
// as this is an AJAX enabled tree, both will be downloaded from the server
"initially_open": ["node_2", "node_3"]
}
