Jquery從段落中刪除行換行

Question

我需要幫助...我有一個帶有編號行的長段。我需要刪除它的linebreak一行。

E.g

1|ncubicx|http%3A%2F%2Fwww.ncubicx.com 
2|asd|fdf 
3|asd|asd 
4|as|asd 
5|sds|sds 
6|asa|asa 
7|asd|fdf 
8|google|https%3A%2F%2Fwww.google.com 
9|flipkart|http%3A%2F%2Fwww.flipkart.com%2F 
10|amazon|https%3A%2F%2Fwww.amazon.co.in 

上述一個被包含在可變str。我想用jQuery刪除第二個條目。 使得結果變成這樣......

1|ncubicx|http%3A%2F%2Fwww.ncubicx.com 
3|asd|asd 
4|as|asd 
5|sds|sds 
6|asa|asa 
7|asd|fdf 
8|google|https%3A%2F%2Fwww.google.com 
9|flipkart|http%3A%2F%2Fwww.flipkart.com%2F 

10 |亞馬遜| HTTPS％3A％2F％2Fwww.amazon.co.in

但是當我使用：

oldrep="2|asd|fdf";  
var res = str.replace(oldrep, ""); 

我得到了一個空白行之間像下面...

1|ncubicx|http%3A%2F%2Fwww.ncubicx.com 

3|asd|asd 
4|as|asd 
5|sds|sds 
6|asa|asa 
7|asd|fdf 
8|google|https%3A%2F%2Fwww.google.com 
9|flipkart|http%3A%2F%2Fwww.flipkart.com%2F 
10|amazon|https%3A%2F%2Fwww.amazon.co.in 

我需要刪除整條生產線... 怎麼做？任何幫助表示讚賞...

Answer 1

var x = `1|ncubicx|http%3A%2F%2Fwww.ncubicx.com 
2|asd|fdf 
3|asd|asd 
4|as|asd 
5|sds|sds 
6|asa|asa 
7|asd|fdf 
8|google|https%3A%2F%2Fwww.google.com 
9|flipkart|http%3A%2F%2Fwww.flipkart.com%2F 
10|amazon|https%3A%2F%2Fwww.amazon.co.in`; 

console.log(x.replace("2|asd|fdf\n", "")); 

會做吧..

注意var x = `...`是聲明多行字符串的方式。

Answer 2

做到這一點

最好的辦法是行分流到陣列和刪除線，並加入回

var str = `1|ncubicx|http%3A%2F%2Fwww.ncubicx.com 
2|asd|fdf 
3|asd|asd 
4|as|asd 
5|sds|sds 
6|asa|asa 
7|asd|fdf 
8|google|https%3A%2F%2Fwww.google.com 
9|flipkart|http%3A%2F%2Fwww.flipkart.com%2F 
10|amazon|https%3A%2F%2Fwww.amazon.co.in`; 

var strArray = str.split('\n'); 
strArray.splice(1, 1); 
var newStr = strArray.join('\n');
