您可以通過僅針對我們在內部方法中循環.line_wrap的當前div 中的 div來解決此問題。這是必要的，這樣我們就不會在所有div中一次包裝所有內容：.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>");
});

1 - The first of the month is coming, we have to get money, we have no choice. It cost money to eat and they don’t want you to eat. Egg whites, turkey sausage, wheat toast, water. Of course they don’t want us to eat our breakfast, so we are going to enjoy
our breakfast. They key is to have every key, the key to open every door. To succeed you must believe. When you believe, you will succeed. They don’t want us to eat. 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. To be successful you’ve got to work hard, to make history, simple, you’ve got to make it. The key to success is to keep your head above the water, never give up. Stay focused. 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. Major key, don’t fall
for the trap, stay focused. It’s the ones closest to you that want to see you fail. They never said winning was easy. Some people can’t handle success, I can. Another one. You smart, you loyal, you a genius. Look at the sunset, life is amazing,
life is beautiful, life is what you make it. The key to success is to keep your head above the water, never give up. They don’t want us to eat. Put it this way, it took me twenty five years to get these plants, twenty five years of blood sweat
and tears, and I’m never giving up, I’m just getting started.
