I’m a bit new to JavaScript and I’m hitting a brick wall with this

  • 0

I’m a bit new to JavaScript and I’m hitting a brick wall with this bit here.

I have a jsTree built with unique IDs based on filenames. For example, 

<a id="node_:Folder4" href="#">Folder4</a>

Running a selector for 

$("#node_:Folder4")

is returning [ ]. Here’s a picture of the exact issue I’m seeing. Any thoughts?

    You need to escape the colon:

    $('#node_\\:Folder4')

    Not sure why, but I found this document here that says

    ID and NAME tokens must begin with a letter ([A-Za-z]) and may be
    followed by any number of letters, digits ([0-9]), hyphens (“-“),
    underscores (“_”), colons (“:”), and periods (“.”).

    I’m probably looking at deprecated document, but yes, try to avoid using special characters on attributes values
