问题 First the code can be found here: working - almost - code I've had a few pointers and learnt "quite a bit" along to way trying to get this to work. Basically I'm building, or trying to build a hierachy tree for office staff with some basic functions.

Problem: If you hold the mouse over a node, 4 little pop up menus appear - the green and the red add and remove nodes

问题 Is there a way to make it so that if the page inside an iframe is not the src, then it will change the parent page to the url the iframe is trying to go to?

问题 When I save a new Report, NHibernate inserts the Report, ignores the Publication and tries to insert the UserPublication. However SQL then complains about violation of FK constraint. Its like NHibernate doesn't think the Publication is new even though the row doesn't exist in the db. Think of the entity relationship as: A Report can have many Publications (Publications belong to a Report) A Publication can have many UserPublications (UserPublications belong to a Publication) Any ideas what I

问题 My app wants to copy a file from a private app folder to a SAF folder that was created inside an user-selected SAF folder. Folder creation is Ok.

问题 So I have an array of items in php, some may be linked to others via a parent_id key. I'm looking to sort this array so that any items whose parent is in this array ends up positioned right below the parent. example: (actual array has many more keys) some_array[0]['id'] = 15001; some_array[0]['parent_id'] = 14899; some_array[1]['id'] = 14723; some_array[1]['parent_id'] = 0; //parent_id of 0 means item has no parent of its own some_array[2]['id'] = 14899; some_array[2]['parent_id'] = 0; some

问题 I have successfully removed the parent slug from URL and have reduced the URL from: http://myexp.uphero.com/sample-page/child-sample-page/ to http://myexp.uphero.com/child-sample-pagee/ This is a test wordpress website for testing purposes.

I am having the child iframe update one of the parent's global variables with parent.myvar = "myvalue"; Works great (note: everything is on the same domain). Now I need to run the function in the parent to complete the process. Problem: parent.myfunction(); I have just run the function I need minus any of the global variables in the parent file (it is being executed within the child iframe). Of course, I could bring

问题 If I had some thing like this: <div id="parent"> <iframe....></iframe> </div> I could: window.parent.document.getElementById('parent').innerHTML. But I have something like this: <div> <iframe....></iframe> </div> Is there anyway of accessing this? I might have anywhere up to 20 iframes on a given page, and would prefer not to make 20 individual iframe pages. Thanks, Jason 回答1: window.frameElement is a reference to the IFRAME element containing the current page. You can use window.frameElement
