Use JS to get the ID of the control with focus:

Copy the code The code is as follows:

$("#textID").click(function(){
var act = document.activeElement.id;
if(act == "textID" ){
alert( "true");
}else{
alert("false");
}
} );

Use jquery to get the ID of the control with focus: var act = $(document.activeElement).attr("id");
