Thoughts on Treeview

The Treeview value has been bound and you do not want to change the original structure. For example, the value of the bound Treeview is directly written to it, which is equivalent to the value written to it, in this case, how can I display different lists based on different roles? We can bind all the value options first. By observing the HTML file during execution, we can find that each item has an ID. At this time, we can use

VaR ele = Document. getelementbyid ("tvmenut3"). parentelement. parentelement;

Ele. style. Display = "NONE ";

To hide the items to be filtered. This can also meet the requirements of different display options based on different roles.
