I am extracting data from a database that I do not administer. It is a single list, and the important values are:
I have successfully created a Tree-structured browser, based on a model using
<li> tags. I had also implemented action listeners on double click, that found the id, and acted accordingly. The identifications were stored, and found as a
value-parameter to the individual
<li>'s that represented the leaves, or filenames.
However it turns out that the Index numbers are not unique. I expected them to be, even though there were a column for
UID's. I tried to set the
value to be the
UID String. It works in my browser, as a snippet of my generated HTML code shows:
<li role="treeitem" value="1581f20c-0ef9-4c21-a8ab-a407da310cf5" ... >
However, when I retrieve the value, and save it to database, it only gets the numeric value that appears ahead of the first non-numeric character. In this case 1581. I've checked, and come to the conclusion that the value-parameter only accepts numeral values, which really sucks for me...
Are there any other ways to tie a non-displayed UID String to a HTML-list element?
I removed my previous edit, due to a realization of what my misunderstanding was. Custom data tags needs the syntax "data-variablename", and when retrieving it, I should ommit the "data-", and just get the variablename.
value is already an html attribute. So the browser try to fix your value when you use it. Try to use a custom attribute like
<li role="treeitem" data-value="1581f20c-0ef9-4c21-a8ab-a407da310cf5" ... >
