QUESTION
I have got a fancytree like that:
...ANSWER
Answered 2018-Jul-14 at 04:38Fancytree maintains an invisible root node. If you pass a list of children, they will appear as top-level nodes.
In order to create one visible top-level node, you should pass one node with a list of children (how would you define its title and other properties otherwise?):
QUESTION
Solved : to get the id of the previous element, use previousElementSibling.id
instead of previousSibling.id
. Thank you to Xufox and Skyline3000 who quickly provided the solution.
Having some breadcrumbs done of anchors elements, I'm trying to get the id of the previous sibling when one breakcrumb is clicked (i.e. the parent category).
eg. Fruits> Apples> Green apples
Unfortunately, my code does not work.
alert(this.previousSibling)
returns[object Text]
alert(this.previousSibling,id)
returnsid is undefined
.alert(this.previousSibling,getAttribute(\'id\')
returnsTypeError: this.previousSibling.getAttribute is not a function
.alert(this.previousSibling,attr(\'id\'))
returnsTypeError: this.previousSibling.attr is not a function
.
I assume that the sibling is not correctly reached as I was expecting some Element or Object and not Text.
Here's what the HTML and javascript of two breadcrumbs look like:
...ANSWER
Answered 2018-Apr-06 at 16:21All text and whitespace, including whitespace and new lines between your HTML tags, count as a TextNode. Thus the tag's previous sibling is actual the textNode of whitespace between the tags. What you really want to do is find the previous sibling that is an element (HTML tag).
