回答1:

If you want to redirect user simulating anchor click, then call native DOM click method:

$("#menu-item-29").children('a').get(0).click();

回答2:

Don't forget to include JQuery source when you use $(document).ready

And children() is a function. Look at the documentation : http://api.jquery.com/children/
