问题 I have a page which uses jquery's ajax functions to send some messages. There could be upwards of 50k messages to send. This can take some time obviously. What I am looking to do is show a progress bar with the messages being sent. The backend is PHP. How can I do this? My solution: Send through a unique identifier in the original ajax call.

问题 I'm trying to change the color of bar in ProgressBar with pBar.setStyle("-fx-accent: green"); but I have encountered a problem: that doesn't seem to work right for me!

问题 I have an Ajax call that updates 5,000 records in a database so this takes a lot of time. I have an Ajax "Loading image" showing that something is happening, but I am looking for a better way to show "Updating 50 of 5000 . . .", "Updating 200 of 5000", or something like that.
