我的任务
分享JavaScript如何把整篇文章里的空格替换成换行符, 或把每一个句子分离成独立一行??
I am an apple.
变成:
I
am
an
apple
.
第二种是句子处理:
You are stupid! Come here. I will tell you the truth. Where you now?
变成:
You are stupid!
Come here.
I will tell you the truth.
Where you now?
============================================================
用户输入框:
<div><textarea id="c"cols="136"rows="88"></textarea></div>电脑输出结果框:
<div><textarea id="s1"cols="136"rows="88"readonly="readonly"ondblclick="sa()"></textarea></div>
<div><textarea id="s2"cols="136"rows="88"readonly="readonly"ondblclick="sb()"></textarea></div>注意是替换整篇文章. 不是替换第一个字符. 看过一些例子, 好像是要加
/g
function sa(){s1.value=c.value.replace(/ /g,\n);}
function sb(){s2.value=c.value.replace(/每个句子/g,\n);}
上面的JavaScript代码有问题, 真不会写.
非常感谢神仙 和 妖怪帮忙!

function sa(){s1.value=c.value.replace(/\s+/g, "\n");}
function sb(){s2.value=c.value.replace(/([^\w+ ])/g, "$1\n");}
