我正在使用 JStree 显示 XML 文件，显示后用户可以创建、重命名或删除某些节点，并且确保这些更改仅出现在显示的 xml 上，而不反射(reflect)在原始文件上，我想知道如何在单击提交按钮后将这些更改反射(reflect)到原始 XML 文件中，或者至少如何更改数据。

$.ajax({

url: _url,
dataType:"xml",
cache: false,
beforeSend:function(){
//do something before send

success: function(data){
processXML(data);
},
error:function(e){
alert("Error: "+e);

以及UIMtreeprocessor库代码
function UIMTreeProcessor(data, treeEl) {
this.data = data;
this.treeEl = treeEl;
}
UIMTreeProcessor.prototype.initTree = function(data){
this.treeEl.jstree({
"json_data" : {
"data":data,
"progressive_render":"true"
},
"plugins" : ["themes","json_data","ui","crrm","cookies","dnd","search","types","hotkeys","contextmenu"],
"core":{"animation":0}
});
}
UIMTreeProcessor.prototype.doProcess = function(){
//Find root:
var _root = $(this.data).children(':first-child');
var _a_feed = new Array();
this.vsTraverse($(_root), _a_feed);
var _treedata = [{"data":_root[0].nodeName,"children":_a_feed, "state":"open"}];
this.initTree(_treedata);
}
UIMTreeProcessor.prototype.vsTraverse = function(node, arr){
var _ch = $(node).children();
for(var i=0; i<_ch.length; i++){
var _vsArr = new Array();
this.vsTraverse(_ch[i], _vsArr);
var _a_att = this.vsTraverseAtt(_ch[i]);
if(null!=_a_att){
_vsArr.push([{"data":"Attributes "+"["+_ch[i].nodeName+"]","children":_a_att, attr : { "class" : "uim_attr"}}]);
}
if(null!=_ch[i].firstChild && 3==_ch[i].firstChild.nodeType){
arr.push([{"data":_ch[i].nodeName + ": " + _ch[i].firstChild.textContent,"children":_vsArr, "state":"open"}]);
}else{
arr.push([{"data":_ch[i].nodeName,"children":_vsArr, "state":"open"}]);
}
}
}
UIMTreeProcessor.prototype.vsTraverseAtt = function(node){
var _a_atts = null;
if(null!=node.attributes && node.attributes.length > 0){
_a_atts = new Array();
for(var i=0; i<node.attributes.length; i++){
_a_atts.push(node.attributes[i].nodeName + ":" + node.attributes[i].nodeValue);
}
}
return _a_atts;
}
最佳答案
编辑:我原来的答案确实是错误的。
xml_data中有一个get_xml方法插件，它应该做你所描述的事情。我自己还没有测试过它，但如果它是类似于 json_data.getJSON 的内容，输出将包含您不希望将其放回 XML 中的各种 JStree 元数据。
