您可以通过仅针对我们在内部方法中循环.line_wrap的当前div 中的 div来解决此问题。这是必要的，这样我们就不会在所有div中一次包装所有内容：.wrapped.each().line_wrap.wrapped$(".emails .multi-items .wrapped").each(function (i) {    $('.line_wrap', this).wrapAll("<div class='test'></div>");});工作演示：function wrapNewLines(targetSelector, wrapEl = 'span', wrapClass = 'new-line') {  const content = document.querySelectorAll(targetSelector)  content.forEach(section => {    let sectionWidth = section.getBoundingClientRect().width    let words = section.innerText.split(/( )/g)    section.innerHTML = ''    words.forEach(word => {      section.innerHTML += `<span>${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 {  background: black;  color: white}.line_wrap {  border: 1px solid #aa0000;  padding: 4px 8px;}#content {  margin: 35px}.test {  color: yellow}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><div class="emails">  <ul class="multi-items">    <div class="message-contain">      <div id="content">        1 - The first of the month is coming, we have to get money, we have no choice.

只需删除 children 函数，因为您想包装 jQuery 集合本身。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    }    $(item).appendTo(container); //add the item to the container   });});$('.wrapped').each(function () {  $(this).find('.line_wrap').wrapAll("<div class='test'></div>")});.wrapped {background:black;color:white}.line_wrap {border:1px solid #aa0000}#content {margin:35px}.test {color:yellow}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><div class="emails"><ul class="multi-items">  <div class="message-contain">      <div id="content">                    1 -  The first of the month is coming, we have to get money, we have no choice.

您可以尝试使用.wrapped元素创建一个循环，找到.line_wrap里面的所有元素并将它们包装起来：$('.wrapped').each(function () {    $(this).find('.line_wrap').wrapAll("<div class='test'></div>")});function wrapNewLines(targetSelector, wrapEl = 'span', wrapClass = 'new-line') {    const content = document.querySelectorAll(targetSelector)    content.forEach(section => {      let sectionWidth = section.getBoundingClientRect().width      let words = section.innerText.split(/( )/g)      section.innerHTML = ''      words.forEach(word => {        section.innerHTML += `<span>${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    }    $(item).appendTo(container); //add the item to the container   });});$('.wrapped').each(function () {  $(this).find('.line_wrap').wrapAll("<div class='test'></div>")});.wrapped {background:black;color:white}.line_wrap {border:1px solid #aa0000}#content {margin:35px}.test {color:yellow}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><div class="emails"><ul class="multi-items">  <div class="message-contain">      <div id="content">                    1 -  The first of the month is coming, we have to get money, we have no choice.
