Split string with commas to new line
提问by Andy
I have a string like
我有一个像
This is great day, tomorrow is a better day, the day after is a better day, the day after the day after that is the greatest day
I wanted to basically split this one long string at the commas and insert a new line so it becomes
我想基本上在逗号处拆分这个长字符串并插入一个新行，这样它就变成了
This is great day
tomorrow is a better day
the day after is a better day
the day after the day after that is the greatest day
How can I do that ?
我怎样才能做到这一点 ？

With the built in splitand joinmethods
var formattedString = yourString.split(",").join("\n")
If you'd like the newlines to be HTML line breaks that would be
如果您希望换行符是 HTML 换行符，那就是
var formattedString = yourString.split(",").join("<br />")
This makes the most sense to me since you're splitting it into lines and then joining them with the newline character.
这对我来说最有意义，因为您将它分成几行，然后用换行符将它们连接起来。
Although I think speed is less important than readability in most cases, I was curious about it in this case so I've written a quick a benchmark.
虽然我认为在大多数情况下速度不如可读性重要，但在这种情况下我很好奇所以我写了一个快速的基准测试。
It seems that (in chrome) using str.split(",").join("\n")is faster than str.replace(/,/g, '\n');.
似乎（在 chrome 中）使用str.split(",").join("\n")比str.replace(/,/g, '\n');.

You could also replace them:
你也可以替换它们：
string.replace(/,/g, '\n');

<p id="errorMessage">Click | the |button |to |display| the| array| values|
after| the| split.</p>
$(document).ready(function () {
var str = $("#errorMessage").text();
document.getElementById("errorMessage").innerHTML=str.split("|").join("
</br>"); }

> a = 'This is great day, tomorrow is a better day, the day after is a better day, the day after the day after that is the greatest day'
> b = a.split(', ').join('\n')
"This is great day
tomorrow is a better day
the day after is a better day
the day after the day after that is the greatest day"

You can use .split()to create an array of all the parts of the string...
您可以使用.split()创建字符串所有部分的数组...
var str = 'This is great day, tomorrow is a better day, the day after is a better day, the day after the day after that is the greatest day';
str.split(',');
-> ["This is great day", " tomorrow is a better day", " the day after is a better day", " the day after the day after that is the greatest day"]
Now, you can do whatever you want with the different parts. Since you want to join with a new line, you can use .join()to put it back together...
现在，您可以对不同的部分做任何想做的事情。既然你想加入一个新行，你可以用.join()把它重新组合起来......
str.split(',').join('\n');
-> "This is great day
tomorrow is a better day
the day after is a better day
the day after the day after that is the greatest day"

Without testing on my browser try:
无需在我的浏览器上进行测试，请尝试：
var MyStr="This is great day, tomorrow is a better day, the day after is a better day, the day after the day after that is the greatest day";
Var splitedStr = MyStr.split(",");
var returnStr = '';
for (var i = 0; i < splitedStr.length; i++)
{
returnStr += splitedStr[i] + '<br />';
}
document.write(returnStr);
