I would like to start using Dynatree on my page, however I will probably need searching my tree by name. Do you know maybe how to do this?
I needed to have not only matching nodes, but also the whole paths to these nodes. I wrote this functionality and it works for me.
Modifications for library:
var clear = true;
DynaTreeNode.prototype.search = function(pattern){
if(pattern.length < 1 && !clear){
clear = true;
this.visit(function(node){
node.expand(true);
node.li.hidden = false;
node.expand(false);
});
} else if (pattern.length >= 1) {
clear = false;
this.visit(function(node){
node.expand(true);
node.li.hidden = false;
});
for (var i = 0; i < this.childList.length; i++){
var hide = {hide: false};
this.childList[i]._searchNode(pattern, hide);
}
}
},
DynaTreeNode.prototype._searchNode = function(pattern, hide){
if (this.childList){
// parent node
var hideNode = true;
for(var i = 0; i < this.childList.length; i++){
var hideChild = {hide: false};
this.childList[i]._searchNode(pattern, hideChild);
hideNode = hideNode && hideChild.hide;
}
if(hideNode && !this._isRightWithPattern(pattern)){
this._hideNode();
hide.hide = true;
} else {
hide.hide = false;
}
} else {
// leaf
if (!this._isRightWithPattern(pattern)){
this._hideNode();
hide.hide = true;
} else {
hide.hide = false;
}
}
},
DynaTreeNode.prototype._isRightWithPattern = function(pattern){
if((this.data.title.toLowerCase()).indexOf(pattern.toLowerCase()) >= 0){
return true;
}
return false;
},
DynaTreeNode.prototype._hideNode = function(){
if(this.li) {
this.li.hidden = true;
}
}
Use:
$("tree").dynatree("getRoot").search(pattern);
