在Ionic 3中将\ r \ n字符转换为新行 [英] Convert \r\n characters to new line in Ionic 3

问题描述

我希望能够将字符串中的\ r \ n个字符转换为新行

I want to be able to convert \r\n characters in a string to new lines

示例 约翰现在正在等待.\ r \ n我们能告诉您有关他的情况吗? \ r \ n他是一个伟大的人

Example John is waiting now.\r\nCan we tell you about him. \r\nHe is a great person

转换为

约翰现在正在等待.

我们能告诉你关于他的事吗?

Can we tell you about him.

他是一个伟大的人

尝试过但无济于事

nl2br(text: string) {
    return text.replace(new RegExp('\r?\n','g'), '<br />');
}

推荐答案

我认为问题可能是由于您的\r\n字符因为过度转义"而可见的.

I think the problem might be due to the fact that your \r\n characters might be visible because they are "over escaped".

此外，我不知道要执行替换的确切上下文，但我认为您不必用<br/>

Furthermore I don't know exactly the context your replace has to be performed but I don't think you have to replace them by a <br/>

因此，您可以做一些愚蠢的事情

You could thus do something silly like

nl2br(text: string) {
    return text.replace('\\r\\n', '\n');
   //or return text.replace('\\r\\n', '<br/>') if it is really what you need
}

还请注意，如果您同时使用了转义的\n和\r，则可以

Note also that if you have a mix of escaped \n and \r, you can

nl2br(text: string) {
    return text.replace(/\\r\\n|\\r|\\n/gi, '\n');
   //or ...'<br/>');
}
