添加換行符（例如8）字

Question

我正在尋找一個腳本來在一些單詞後面換行。我在計算器發現這個位置：Applying a style to and inserting a line break after the first word in a link

所以，我改變了一點：

var el = $('.wtt'); //where wtt is the class of the elements that you want to add the <br /> 
var text = obj.html(); 
var parts = text.split(' '); 
//number 7 represents 8 words 
$('.wtt').html($('.wtt').html().replace(parts[7],parts[7]+'<br />')); 

Answer 1

下面將與<br>

var text = 'hello there purple giraffe, how are you doing today.'; 
alert(text.replace(/^((\S+\s+){7}\S+)\s+/, '$1<br>')); 

\S+替換字符串中的第8個空格可以匹配一個或更多的非空間字符。 \s+匹配一個或多個空格字符。
