Delete row after predefined row

Question

I pull the content out of the RSS feed before using jquery to format and edit the rss returned string (s). I use replace to replace strings and characters as follows:

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

This works great. I am also trying to delete all text after a certain point. Like truncation, I would like to hide the entire text, starting with the word "Example".

In this particular RSS feed, an example of a word is in each feed. I would like to hide the "example" , and all the text follows that word. How can i do this?

Answer 1

Although jQuery is not enough, you don’t even need to delete it after a certain word in a given line. The first approach is to use substring :

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

The second is the split trick:

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

Answer 2

If you also want to save the “Example” and simply delete everything after this 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 

Answer 3

jQuery is not intended for string manipulation, you should use Vanilla JS for this:

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

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

Answer 4

I would like to hide all text starting with the word "Example"

A solution that uses a simpler replacement of links to feedback to “hide” everything, starting with the word “Example”, but keeping the material in front of it.

 var str = "my house example is bad" str.replace(/(.*?) example.*/i, "$1") // returns "my house" // case insensitive. also note the space before example because you // probably want to throw that out.
