替换所有“\n"与“，" [英] Replace all "\n" with ","

问题描述

我有一个 textarea，我想用,"替换它的值中的\n".

I have a textarea and I want to replace "\n" with "," in it's value.

var valuetxtarr = $("#txtarr").val();
var valuetxtarrs = valuetxtarr.replace("/\n/g",",");
alert(valuetxtarrs);

但它不起作用?为什么?我哪里出错了?

But it don't work?Why?Where I have mistake?

推荐答案

你只需要去掉引号(否则它正在寻找那个字符串)，像这样:

You just need to remove the quotes (otherwise it's looking for that string), like this:

var valuetxtarr = $("#txtarr").val();
var valuetxtarrs = valuetxtarr.replace(/\n/g,",");
alert(valuetxtarrs);​
