替换换行符以使它们使用jquery [英] replace linebreaks to get them working with jquery

问题描述

我提交了一些小脚本来预览一些文本，然后再将其提交到数据库中存储：

I have following small script to preview some text before submitting it to store in a database:

jQuery(function($) {
    var input = $('#contents'),
    preview = $('#previewaccordion div.viewcontents');

    input.keyup(function(e) {
        preview.html(input.val());
    });
});

但是如果我用换行符键入文本，它会忽略它们并将所有这些写入一行。我怎么能更换换行符以便它们正确显示？

but if I type text with line-breaks it ignores them and writes all of them in one line. How could I replace the line-breaks so that they show correctly?

推荐答案

我假设您使用textarea输入。有\ n用作换行符，它们对HTML没有影响。所以你必须用br-tags替换它们：

I assume that you are using a textarea for the input. There are \n used as linebreaks, which have no influence in HTML. So you have to replace them with br-tags:

input.val().replace(/\n/g, "<br />");
