在预定义字符串后删除字符串

问题描述

在使用 jquery 格式化和编辑返回的 RSS 提要(字符串)之前，我正在从 RSS 提要中提取内容.我正在使用 replace 来替换字符串和字符，如下所示:

I am pulling content from an RSS feed, before using jquery to format and edit the rss feed (string) that is returned. I am using replace to replace strings and characters like so:

var spanish = $("#wod a").text();
var newspan = spanish.replace("=","-");
$("#wod a").text(newspan);

这很好用.我还试图在某个时间点后删除所有文本.与截断类似，我想隐藏从示例"一词开始的所有文本.

This works great. I am also trying to remove all text after a certain point. Similar to truncation, I would like to hide all text starting from the word "Example".

在这个特定的 RSS 提要中，示例这个词出现在每个提要中.我想隐藏 "example" 和该单词后面的所有文本.我怎样才能做到这一点?

In this particular RSS feed, the word example is in every feed. I would like to hide "example" and all text the follows that word. How can I accomplish this?

推荐答案

虽然没有足够的 jQuery，您甚至不需要它来删除给定字符串中某个单词之后的所有内容.第一种方法是使用substring:

Though there is not enough jQuery, you even don't need it to remove everything after a certain word in the given string. The first approach is to use substring:

var new_str = str.substring(0, str.indexOf("Example"));

第二个是split的技巧:

var new_str = str.split("Example")[0];
