I've applied keyboard navigation on combotree, it works properly.
But, when i click the tree panel the navigation doesn't work at all.
I've solved that by add tree extend for keyboard navigation, and it works (thank for the forum's solution)
The problem appears when i enter the node on tree panel, the cursor doesnt want to focus on textbox (validatebox).
Any one can solve it?
here the tree navigation code:
$.extend($.fn.tree.methods, {
highlight: function(jq, target){
return jq.each(function(){
$(this).find('.tree-node-selected').removeClass('tree-node-selected');
$(target).addClass('tree-node-selected');
})
},
nav: function(jq){
return jq.each(function(){
var t = $(this);
t.attr('tabindex',0);
t.unbind('.tree').bind('keydown.tree', function(e){
var curr = getCurr();
if (!curr.length){return}
if (e.keyCode == 40){ // down
var li = getNext(curr);
if (li.length){
t.tree('highlight', li[0]);
}
} else if (e.keyCode == 38){ // up
var li = getPrev(curr);
if (li.length){
t.tree('highlight', li[0]);
}
} else if (e.keyCode == 13){
t.tree('select', curr[0]);
} else if (e.keyCode == 39){ // right
if (!t.tree('isLeaf', curr[0])){
t.tree('expand', curr[0]);
}
} else if (e.keyCode == 37){ // left
if (!t.tree('isLeaf', curr[0])){
t.tree('collapse', curr[0]);
}
}
e.preventDefault();
}).bind('mouseover.tree', function(e){
var node = $(e.target).closest('div.tree-node');
if (node.length){
t.find('.tree-node-hover').each(function(){
if (this != node[0]){
$(this).removeClass('tree-node-hover');
}
})
}
});
function getCurr(){
var n = t.find('.tree-node-hover');
if (!n.length){
n = t.find('.tree-node-selected');
}
return n;
}
function getNext(curr){
var n = $();
var node = t.tree('getNode', curr[0]);
if (t.tree('isLeaf', node.target)){
n = curr.parent().next().children('div.tree-node');
if (!n.length){
var p = t.tree('getParent', curr[0]);
if (p){
n = $(p.target).parent().next().children('div.tree-node');
}
}
} else {
if (node.state == 'closed'){
n = curr.parent().next().children('div.tree-node');
} else {
var cc = t.tree('getChildren', curr[0]);
if (cc.length){
n = $(cc[0].target);
}
}
}
return n;
}
function getPrev(curr){
var n = curr.parent().prev().children('div.tree-node');
if (n.length){
var node = t.tree('getNode', n[0]);
if (node.state == 'open'){
var cc = t.tree('getChildren', node.target);
if (cc.length){
n = $(cc[cc.length-1].target);
}
}
} else {
var p = t.tree('getParent', curr[0]);
if (p){
n = $(p.target);
}
}
return n;
}
})
}
});here the apply it :
$(function(){
var t=$('#cbtree').combotree('tree');
t.tree('nav');
t.bind('keydown.tree', function(e){
if (e.keyCode == 13){
var node= t.tree('getSelected');
$('#cbtree').combotree('setText',node.text);
$(node.target).trigger('dblclick');
$('#cbtree').focus();
//$('#cbtree').combotree('hidePanel');
}
})
})
