英文:
Count Characters Including the Break Line of an HTML TAG
问题
我有一个正则表达式来移除HTML标签以计算我的字符数。目前它正常工作。
<string_variable>.replaceAll("<(.|\n)*?>","").replaceAll(" "," ").replaceAll("&","&");
alert <string_variavle>.length()
但我需要添加<br/>（换行符）以计算我的字符数。
<div>ABC<br /><br />DEC</div>
例如，上面的ABC和DEC有6个字符，有2个换行符，应该是9个字符。目前它只计算为6个字符。

英文:
I have a regex to remove the html tags to count my characters. Which is working fine.
<string_variable>.replaceAll("<(.|\n)*?>","").replaceAll("&nbsp;"," ").replaceAll("&amp;","&");
alert <string_variavle>.length()
But I need to add the <br/> (New Line) to count my characters.
> <div>ABC<br /><br />DEC</div>
For example above ABC and DEC are 6 characters with 2 break lines it should be 9. As of now it is just counting with 6 characters.

你可以系统地将所有的\n替换为不同的字符，然后使用长度：
const temp = myVar.replaceAll("\n", "a")
console.log(temp.length)
英文:
You can systematically replace all of your \n to a different char and then use the length:
const temp = myVar.replaceAll("\n", "a")
console.log(temp.length)

let str = `
<div>
abc
</div>
<div>
abc
</div>`
console.log(countNewlines(str))
function countNewlines(input) {
let count = 0;
for (let i = 0; i < input.length; i++) {
if (input[i] === '\n') {
count++;
}
}
return count;
}
