Question

使用JavaScript进行一些文本交换（推荐/淡入淡出），并希望在引号内插入等效的<br/>，以便引用的作者在下一行。在下面的代码中，我尝试按照JavaScript: How to add line breaks to an HTML textarea?上的说明操作，但我不确定如何插入/\n\r?/g以使其正常工作。

<script type="text/javascript">
    var text = document.forms[0].txt.value;
    text = text.replace(/\n\r?/g, '<br />');
</script>

<script type="text/javascript">

    window.testimonials = [
        '"This was a great experience" /\n\r?/g - Max Cameron, ThinkTank',
        '"This was a great experience" /\n\r?/g - Max Cameron, ThinkTank',
        "source code"
    ];
</script>

有没有办法强迫它进入下一行？谢谢！

Answer 1

你在做一些非常奇怪的事情。为什么要在变量中插入“正则表达式”？

试试这个：

<script type="text/javascript">
    var text = window.testimonial; // or maybe: document.forms[0].txt.value;
    text = text.replace(/\n\r?/g, '<br />');
    alert(text);
</script>

<script type="text/javascript">

    window.testimonials = [
        '"This was a great experience" \n - Max Cameron, ThinkTank',
        '"This was a great experience" \n - Max Cameron, ThinkTank',
        "source code"
    ];
</script>

/\n\r?/是一个正则表达式：'newline'后跟0或1'回车'。

值'/\n\r?/'是一个字符串，可能如下所示：

Borrowing from what you linked to:

window.testimonials = [
'"This was a great experience" /\n\r?/g - Max Cameron, ThinkTank'.replace(/(\n\r?)|(,)/g, '<br />');,
'"This was a great experience" /\n\r?/g - Max Cameron, ThinkTank'.replace(/(\n\r?)|(,)/g, '<br />');,
"source code"];
