How to wrap all children elements in a class?


I have a function that splits all lines in an element and wraps them in a <div>. For example, if I have an element that looks like:

<div class="test">
  Lorem Khaled Ipsum is a major key to success. I’m up to something. To be successful you’ve
  got to work hard, to make history, simple, you’ve got to make it. I told you all this before, when 
  you have a swimming pool, do not use chlorine, use salt water, the healing, salt water is the healing. 
  The key to more success is to get a massage once a week, very important, major key, cloth talk. 
  Wraith talk. Don’t ever play yourself. 
</div>

Then it wraps all lines like this:

<div class="test">
  <div class="line_wrap">Lorem Khaled Ipsum is a major key to success. I’m up to something. To be successful you’ve</div>
  <div class="line_wrap">got to work hard, to make history, simple, you’ve got to make it. I told you all this before, when </div> 
  <div class="line_wrap">you have a swimming pool, do not use chlorine, use salt water, the healing, salt water is the healing. </div> 
  <div class="line_wrap">The key to more success is to get a massage once a week, very important, major key, cloth talk. </div> 
  <div class="line_wrap">Wraith talk. Don’t ever play yourself.</div> 
</div>

The problem I'm having is I'm looking for a way to wrap those items in another <div> like:

<div class="test">
  <div class="wrap">
    <div class="line_wrap">Lorem Khaled Ipsum is a major key to success. I’m up to something. To be successful you’ve</div>
    <div class="line_wrap">got to work hard, to make history, simple, you’ve got to make it. I told you all this before, when </div> 
    <div class="line_wrap">you have a swimming pool, do not use chlorine, use salt water, the healing, salt water is the healing. </div> 
    <div class="line_wrap">The key to more success is to get a massage once a week, very important, major key, cloth talk. </div> 
    <div class="line_wrap">Wraith talk. Don’t ever play yourself.</div> 
  </div>
</div>

So far I've tried to do wrapall using .each function but it does 4 layers of wraps and if I have more than one element, it will take all the elements and put them in the first element.

My question is: How do I wrap all of children into a <div>?

My working code:

function wrapNewLines(targetSelector, wrapEl = 'span', wrapClass = 'new-line') {
    const content = document.querySelectorAll(targetSelector)
    content.forEach(section => {
      let sectionWidth = section.getBoundingClientRect().width
      let words = section.innerText.split(/( )/g)
      section.innerHTML = ''
      words.forEach(word => {
        section.innerHTML += `<span>${word}</span>`
      })
      let lines = []
      let line = []
      let lineWidth = 0
      let spans = section.querySelectorAll('span')
      spans.forEach((span, i) => {
        let spanWidth = span.getBoundingClientRect().width
        if (lineWidth + spanWidth <= sectionWidth - 1) {
          line.push(span)
          lineWidth += spanWidth
        } else {
          lines.push(line)
          line = []
          lineWidth = 0
          line.push(span)
          lineWidth += spanWidth
        }
      })
      if (line.length) lines.push(line)
      let newLines = lines
        .map(
          line =>
            `<${wrapEl} class=${wrapClass}>${line
              .map(span => span.innerText)
              .join('')}</${wrapEl}>`
        )
        .join('')
      section.innerHTML = newLines
    })
}    
wrapNewLines('.emails .multi-items .message-contain #content','div', 'line_wrap');


$.each($('.message-contain'), function(i, message) { 

	var size = 6; //define how many elements you want in each wrapper
	var items = $(message).find('.line_wrap'); //the collection of all your items
	var container; //this will be used to add the items in it.
  
  $.each(items, function(i, item) { 
  
    //this expression checks if we need to create a new container
    if (i % size === 0) {
      container = $('<div class="wrapped"></div>'); //create a new container
      $(message).append(container); //add the new container to the body
    }

    $(item).appendTo(container); //add the item to the container
   });
});
$(".emails .multi-items #content").each(function (i) {
  $('.line_wrap').children().wrapAll("<div class='test'></div>");
});
.wrapped {background:black;color:white}
.line_wrap {border:1px solid #aa0000}
#content {margin:35px}
.test {color:yellow}

Another one. Major key, don’t fall for the trap, stay focused. It’s the ones closest to you that want to see you fail.

They don’t want us to eat. The key is to drink coconut, fresh coconut, trust me. Give thanks to the most high. Surround yourself with angels, positive energy, beautiful people, beautiful souls, clean heart, angel. Congratulations, you played yourself.

The part in question:

$(".emails .multi-items #content").each(function (i) {
  $('.line_wrap').children().wrapAll("<div class='test'></div>");
});

Solution

  • You can fix this issue by targeting only the .line_wrap divs inside the current .wrapped div that we are looping through inside .each() method. This is need so that we do not wrap all the .line_wrap at once inside all .wrapped divs:

    $(".emails .multi-items .wrapped").each(function (i) {
        $('.line_wrap', this).wrapAll("<div class='test'></div>");
    });
    

    Working Demo:

    function wrapNewLines(targetSelector, wrapEl = 'span', wrapClass = 'new-line') {
      const content = document.querySelectorAll(targetSelector)
      content.forEach(section => {
        let sectionWidth = section.getBoundingClientRect().width
        let words = section.innerText.split(/( )/g)
        section.innerHTML = ''
        words.forEach(word => {
          section.innerHTML += `<span>${word}</span>`
        })
        let lines = []
        let line = []
        let lineWidth = 0
        let spans = section.querySelectorAll('span')
        spans.forEach((span, i) => {
          let spanWidth = span.getBoundingClientRect().width
          if (lineWidth + spanWidth <= sectionWidth - 1) {
            line.push(span)
            lineWidth += spanWidth
          } else {
            lines.push(line)
            line = []
            lineWidth = 0
            line.push(span)
            lineWidth += spanWidth
          }
        })
        if (line.length) lines.push(line)
        let newLines = lines
          .map(
            line =>
            `<${wrapEl} class=${wrapClass}>${line
                  .map(span => span.innerText)
                  .join('')}</${wrapEl}>`
          )
          .join('')
        section.innerHTML = newLines
      })
    }
    wrapNewLines('.emails .multi-items .message-contain #content', 'div', 'line_wrap');
    
    $.each($('.message-contain'), function(i, message) {
      var size = 6; //define how many elements you want in each wrapper
      var items = $(message).find('.line_wrap'); //the collection of all your items
      var container; //this will be used to add the items in it.
      $.each(items, function(i, item) {
        //this expression checks if we need to create a new container
        if (i % size === 0) {
          container = $('<div class="wrapped"></div>'); //create a new container
          $(message).append(container); //add the new container to the body
        }
    
        $(item).appendTo(container); //add the item to the container
      });
    });
    
    $(".emails .multi-items .wrapped").each(function (i) {
        $('.line_wrap', this).wrapAll("<div class='test'></div>");
    });
    .wrapped {
