Question

I saved a function created in jQuery in clean.js file..

jQuery.fn.singleDotHyphen = function(){
return this.each(function(){
    var $this = $(this);
    $this.val(function(){
        return $this.val()
            .replace(/\.{2,}/g, '.')
            .replace(/-{2,}/g, '-');    
    });
});
};

My action file is..

<script type="text/javascript">  

$(document).ready(function() {
$.noConflict();
   $('#title').limitkeypress ({ rexp:/^[A-Za-z.\-\s`]*$/ }); 
       $('#title').blur(function() {
           $(this).singleDotHyphen();  
        });
 }); 
 </script>

Issue is onblur its returning me code of the function where as I want to return the string that reject continuous hyphen and dots…

The version of the .val() method that accepts a function argument exists only in jQuery 1.4 and above. However, in this case you don’t need that version, since you can simply pass the new value to val():

$this.val($this.val().replace(/\.{2,}/g, '.')
                     .replace(/-{2,}/g, '-'));
