混合Javascript和jQuery？ [英] Mixing Javascript and jQuery?

问题描述

主要问题：是否可以使用JavaScript条件然后使用一些jQuery代码？

Main Question: Is it possible to use a JavaScript conditional and then use some jQuery code?

这是一个当前不工作的例子：

Here is a currently non-working example:

<script>
//<![CDATA[ 
if (location.pathname == "/SearchResults.asp" 
|| location.pathname.indexOf("-s/") != -1 
|| location.pathname.indexOf("_s/") != -1) 
$('.colors_productname span').css("background-color", "#F7F7F7");
//]]> 
</script>

JavaScript条件由我的电子商务平台（Volusion）提供，仅针对类别页面（jQuery是我这样做。我问他们这个JavaScript代码是否仍然有效，因为我的网址不包含/SearchResults.asp（其中一个实际上是/Meats-s/3393.htm），但是他们向我保证它仍然有用。

The JavaScript conditional was provided by my ecommerce platform (Volusion) to target just category pages (the jQuery was my doing). I asked them if this JavaScript code would still work given that my urls dont include "/SearchResults.asp" (One of them is actually "/Meats-s/3393.htm"), but they assured me that it should still work.

次要问题：location.pathname.indexOf行有什么作用？

Secondary Question: What do the "location.pathname.indexOf" lines do?

推荐答案

jQuery和JavaScript不是单独的语言。 jQuery是一个用Javascript编写的库，所以任何有效的jQuery语句都是有效的JavaScript语句。

jQuery and JavaScript are not separate languages. jQuery is a library written in Javascript, so any valid jQuery statement is a valid JavaScript statement.

Q2：
location.pathname 是您的域名后网址的路径。

Q2: location.pathname is the path of the url after your domain name.

例如 http://www.google.com/s/goo.html - >路径名将返回s / goo.html

e.g http://www.google.com/s/goo.html -> the pathname would return s/goo.html

所以你的if条件试图找出这个字符串是否包含子字符串-s。

So your if condition is trying to find out if this string contains the substring "-s".
