jQuery.noConflict();//与JSF搭配需要这句话，不然会有冲突
jQuery(document).ready(function() {
// Add click event listener to each checkbox in the tree page
// Note! Using this simple selector assumes that there are no other
// checkboxes on the page, if there are other checkboxes then
// selector should be changed
jQuery(":checkbox").click(function(){
updateChildren(this);
updateParent(this);
});
});
