I am pulling content from an RSS feed, and then 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);

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". 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 would I accomplish this with jQuery?

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"));

The second is a trick with split:

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

the split method seems to work just great! –  JCHASE11 Nov 29 '12 at 21:07
How would I wrap example and everything after that in a div? –  JCHASE11 Nov 29 '12 at 21:09
@JCHASE11 Something like that: $("div").text(function(i, val) { return val.split("Example")[0]; });. –  VisioN Nov 29 '12 at 21:11

jQuery isn't intended for string manipulation, you should use Vanilla JS for that:

newspan = newspan.replace(/example.*$/i, "");

The .replace() method accepts a regular expression, so in this case I've used /example.*$/i which does a case-insensitive match against the word "example" followed by zero or more of any other characters to the end of the string and replaces them with an empty string.

If you also want to keep "Example" and just remove everything after that particular word, you can do:

var str = "aaaa1111?bbb&222:Example=123456",
    newStr = str.substring(0, str.indexOf('Example') + 'Example'.length);

// will output: aaaa1111?bbb&222:Example
