Quick Javascript Question

[airjunkie2000]

Ya know how you can use the if function to weed out strings that contain something by using "==". My problem is that I need to weed things out that contain a certain few lters in a certain order. Whats going on id people are spamming the hell out of my comment adding script and I need to block all comments and names that contain www, http, .com, or .net

 

Any help is appreciated

 

Thanks

Hmm... good luck with that. I'm sure there is somebody that can help.

 

What kind of comment form do you have? Is is part of a blog or CMS? (Maybe there is a plugin that would work for you, or something.) Or is it totally home-grown?

[airjunkie2000]

home grown, really basic... I have figured out how to block an exact word, for instance if I just type "www" it will block it, but if I type "www.fjkgsdfjkgs" it will not

[airjunkie2000]

Here is a sam0ple of the if statements. I want to filter it if it "contains" the word or phrase, not if it equals it...

 

//////////////

 

if(document.form1.name.value == "www")

{

alert("No Spamming Please");

document.form1.name.focus();

return false;

}

if(document.form1.comment.value == "www")

{

alert("No Spamming Please");

document.form1.comment.focus();

return false;

}

 

/////////////////

 

see this filters out "www" if you type that, but not www.spamsite.com, any suggestions?

 

Thank you

There is an .indexOf( ) method that returns the position of a string, returning -1 if the string is not found.

 

So, something like:

 

if (document.form1.comment.value.indexOf("www") > -1)

 

might do the trick. Of course, you would probably want to convert to lowercase before making the comparision.

 

Hope this helps.
