"swear filter" | JavaScript | xanga

1 comments

This is a swear filter script I wrote for my xanga blog. I don't know if it has any application anywhere else. This will replace the swear words listed in the array with the character defined in blank_char. This isn't perfect but it works pretty well.

<script language="javascript">

 var divs = document.getElementsByTagName("div");

 var blank_char = "*"; // change this to whatever you want swears words to be blocked out with

 var swear_words = new Array("damn", "shit"); // put words you want to be blocked into this array

 for (var l = 0; l < divs.length; l++) {

 str = divs[l].innerHTML;

        for (var i = 0; i < swear_words.length; i++){                

                rExp = new RegExp(swear_words[i], "i");  

                if ( str.match(rExp) ) divs[l].innerHTML = str.replace (rExp, repeat(swear_words[i].length, blank_char));

        }  

}

function repeat(n, b_chr){

// there is probably a better way to do this, but I'm not that good at JavaScript so if you figure something out feel free to revise

var new_text = "";

for (var e = 0; e < n; e++)

        new_text = new_text + b_chr;

return new_text;

}

</script>
