Regular expression that match a text if it contains a string ONLY once
To check if text contains some substring only once, you need to check match all characters that do not constitute <scr>, then match <scr>, and use a negative look-ahead to check if there is no <scr> further, and consume all characters.

jQuery: Eventhandler works only once
jquery,event-handling,click,once
The problem is, that slider.reloadSlider({ startSlide: currentSlide }); recreates the slider elements. Which breaks the click event handler, since the original button gets replaced. You could change it to .on() and it should work. For example. $('body').on('click','a.bx-next',function() { console.log("Clicked 'next'"); // that happens only once!! steps++; if(steps % 1 ==...

The transaction started extends to...
