A strange error in jquery: "uncaught typeerror: Object # has no method 'tolowercase '"

Today, the ztree. js control seems to be a problem. If the tree is expanded, it cannot be scaled back,

I think it should be a JS issue. Open the browser and enable debugging and find the following error:

 

No solution after Google, step by step troubleshooting, found that the following code is normal after deletion

 

 

<DL> <DT> node name </DT> <DD> <span id = "nodename"> </span> </DD> <DT> node status </DT> <DD> <span id = "nodestatus"> </span> </DD> </dl>

Find the reason, and finally find that the name of this ID seems to be in conflict with jquery

"Nodename"

After changing to "thenodename", ztree. js can be collapse.
