Running a function on click and reversing it on the second click

I have some text that animates off screen, at the moment this runs as soon as the page is refreshed. I need to function to be called when the burger icon is clicked. Then when the icon is open and clicked again I want the function to be reversed if possible with the first character (C) coming back in first.



jQuery("#button").click(function() {
jQuery(".line1").toggleClass("open1");
jQuery(".line2").toggleClass("open2");
jQuery(".line3").toggleClass("open3");
});

(function text_loop(i) {
setTimeout(function() {
if (i <= 15)
$("#logo_text span").eq(i).addClass("slide_out");
i++;
text_loop(i);
}, 100);
})(0);

#burger_container {
background-color: #404041;
display: block;
position: fixed;
top: 0;
left: 0;
bottom: 0;
width: 60px;
z-index: 101;
}

svg {
margin: 20px auto 0 auto;
display: block;
}

#logo_text {
transform: rotate(-90deg);
margin-top: 350px;
font-size: 40px;
color: #ffffff;
font-weight: 700;
}

#logo_text span {
font-weight: 400;
position: relative;
top: 0;
transition: top 1s ease;
}

#logo_text span.slide_out {
top: -60px;
transition: top 0.5s ease;
}

.line1,
.line2,
.line3 {
transition: all 0.3s ease;
}

.open1 {
transform-origin: top left;
transform: translatex(3px) translatey(-1px) rotate(45deg);
width: 33px;
}

.open2 {
opacity: 0;
}

.open3 {
transform-origin: bottom left;
transform: translatex(3px) translatey(1px) rotate(-45deg);
width: 33px;
}

call it as function and your setTimeout will not end wrap it inside curly bracket in if statement

jQuery("#button").click(function() {
  jQuery(".line1").toggleClass("open1");
  jQuery(".line2").toggleClass("open2");
  jQuery(".line3").toggleClass("open3");
  var currentClass = $("#logo_text span").eq(0).attr('class');
  if(currentClass === undefined || currentClass == "slide_in") {
    text_loop(0, 'slide_out');
  }
  else {
    text_loop(0, 'slide_in');
  }
});

function text_loop(i, classname) {
  setTimeout(function() {
    if(i <= 15) {
      $("#logo_text span").eq(i).attr('class', classname);
      i++;
      text_loop(i, classname);
    }
  }, 100);
}
#burger_container {
  background-color: #404041;
  display: block;
  position: fixed;
  top: 0;
  left: 0;
  bottom: 0;
  width: 60px;
  z-index: 101;
}

svg {
  margin: 20px auto 0 auto;
  display: block;
}

#logo_text {
  transform: rotate(-90deg);
  margin-top: 350px;
  font-size: 40px;
  color: #ffffff;
  font-weight: 700;
}

#logo_text span {
  font-weight: 400;
  position: relative;
  top: 0;
  transition: top 1s ease;
}

#logo_text span.slide_out {
  top: -60px;
  transition: top 0.5s ease;
}

#logo_text span.slide_in {
  top: 0px;
  transition: top 0.5s ease;
}

.line1,
.line2,
.line3 {
  transition: all 0.3s ease;
}

.open1 {
  transform-origin: top left;
  transform: translatex(3px) translatey(-1px) rotate(45deg);
  width: 33px;
}

.open2 {
  opacity: 0;
}

.open3 {
  transform-origin: bottom left;
  transform: translatex(3px) translatey(1px) rotate(-45deg);
  width: 33px;
}
