Remove text using JS

Copy linkTweet thisAlerts:
Aug 24.2011

Consider I ahve the following text:

<h4>The quick brown fox jumps over the lazy dog and feels as if he were in the seventh heaven. Why does it jump quick over a dog?</h4>

Now is it possible to use Javascript to scan this peice of text and remove certain words?

If I want to remove “[COLOR=”Green”]and feels[/COLOR]” as well as “[COLOR=”Green”]quick[/COLOR]“

I should end up with this:

<h4>The brown fox jumps over the lazy dog as if he were in the seventh heaven. Why does it jump over a dog?</h4>

Is this possible? If so can someone provide a working example.

Many thanks

@DracoMerestAug 24.2011 — Yes, it is very possible. You need to learn something about Regular Expressions.

aka RegEx and RegExp. There are thousands of tutorials when you search google.

&lt;html&gt;
&lt;script language="javascript"&gt;

inpStr="The quick brown fox jumps over the lazy dog and feels as if he were in the seventh heaven. Why does it jump quick over a dog?"

rAry=new Array("and feels","quick");

for(i=0;i&lt;rAry.length;i++)
inpStr=inpStr.replace(RegExp(rAry[i],"g"),"");

document.write(inpStr);

&lt;/script&gt;
&lt;/html&gt;

@amean_nauthorAug 24.2011 — Thank you for your reply.

And yes, Google is my friend. I tried your code, and it works. However it only works on the text you declare in the var and spits it out without whatever has been specified. What If I wanted the script to scan a page which all ready has the text on it. I.E scan the page and delete/replace certain words.

Thanks ?

Success!
