After deployment headaches how to click A button on the place A selected on A style, and all the oth-CodePudding

The button click event code is as follows, there are three buttons

 
If (buttonA. GetStyleClass (.) indexOf (" button - unselected2 ")!=1) {
ButtonA. GetStyleClass (). Remove (buttonA getStyleClass (). The indexOf (" button - unselected2 ")); 
} 
ButtonA. GetStyleClass (). The add (" button - selected2 "); 

If (buttonB. GetStyleClass (.) indexOf (" button - selected2 ")!=1) {
ButtonB. GetStyleClass (). Remove (buttonB getStyleClass (). The indexOf (" button - selected2 ")); 
ButtonB. GetStyleClass (). The add (" button - unselected2 "); 
} 


If (buttonC. GetStyleClass (.) indexOf (" button - selected2 ")!=1) {
ButtonC. GetStyleClass (). Remove (buttonC getStyleClass (). The indexOf (" button - selected2 ")); 
ButtonC. GetStyleClass (). The add (" button - unselected2 "); 
}

Started with the add directly to three buttons to add corresponding style, but after clicking on a few times more, can appear all button into the style of the button - unselected2,,,,
Interviews after the first remove the add, is that, behind the output under getStyleClass () found around 3-4 times, can appear
The button button - unselected2 button - unselected2 button - selected2
This kind of situation
