偷懒的 JQuery combotree的默认选中

function defaultValue(cbtid,defVal,defText){
var combotree =$("#"+cbtid);
var tree = combotree.combotree('tree');
var defNode = tree.tree("find",defVal);
if(!defNode){
tree.tree('append', {
data: [{
id: defVal,
text: defText
}]
});
defNode = tree.tree("find",defVal);
combotree.combotree('setValue',defVal);
tree.tree('select',defNode.target);
defNode.target.style.display='none';
}else{
combotree.combotree('setValue',defVal);
}
}
