jQuery html（）和换行符 [英] jQuery html() and new line characters

问题描述

我正在使用带有rails的jQuery并拥有以下代码

I'm using jQuery with rails and have the following piece of code

$('#related').html("<%= render :partial => "related_items" %>");

我在浏览器中遇到问题，其中#related元素的内容仅被替换部分中没有换行符。

I'm having a problem in the browser where the content of the #related element is only being replaced when there are no line breaks in the partial.

这不是什么大不了的事，我可以将所有内容放在一行但是它使代码非常难以阅读。

This isn't too much of a big deal, I can place everything on one one line but it makes the code very difficult to read.

有没有办法在jQuery html（）属性中省略换行符？

Is there a way around having to omit line breaks in the jQuery html() attribute?

推荐答案

这里发生的是<％和％> ，并将该解释的输出发送到浏览器。那么发送到浏览器的是：

Whats happening here is the code between the <% and %> is being interpreted by Rails first, and the output of that interpretation is being sent to the browser. So what's being sent to the browser is:

$('#related').html("Some text with a
line break in it");

这不是有效的javascript，因为javascript不允许使用多行双引号字符串。你需要转义字符串中的换行符，这样当它们打印到浏览器时，结果就是一个有效的javascript语句。

This is not valid javascript because javascript doesn't allow multi-line double-quoted strings. You need to escape the line breaks in the string so that when they are printed to the browser the result is a valid javascript statement.
