jquery too much recursion on multiple blur function

I am checking some textboxes on blur, some need to be checked against the same critera so I put these all in one blur function. I have noticed that my page seems slow and in firebug I keep gettin the error too much recursion .

My code is below, it checks the textbox and then sends the ID to another function which adds a class to say if it is valid or not valid.

$('#username, #customerName, #customerTown, #customerCounty, #contactName, #staffFirstname, #staffLastname, #staffTown, #staffCounty').blur(function()
{
   var ID = $(this).attr('id');
       var val = $(this).val();                     
       if(validate(val))
       {
           valid(ID);

       }
       else
       {            
           notValid(ID);
       }

});

function valid(elementID)
{
            $('#'+elementID+'Img').html('<img src="../images/tick.png" alt="Valid" title="Valid" />');
            $('#' + elementID).addClass('valid');

}

function notValid(elementID)
{
            $('#'+elementID+'Img').html('<img src="../images/cross.png" alt="Not Valid" title="Not Valid" />');
            $('#' + elementID).removeClass('valid');                    

}

function validate(val)
    {
        var reg = new RegExp ("^([a-zA-Z ]){3,90}$");
        var regTest = reg.test(val); 
        if(regTest)
        {
            return true;
        }
        else
        {
             return false;
        }
}

Would it be better if I did a开发者_如何学C seprate blur function for each textbox? Or is there another way? I don't really want to write a blur function for every single textbox.

Any suggestions? Thanks.

I tried out your code, and it doesn't show any signs of slowness, and there is no error messages at all, not even in the error console.

Here are some suggested changes in the code, using a single function to set the status instead of two, using jQuery to create elements instead of pasting together HTML code, avoiding the if-true-then-true-else-false antipattern in the validate function:
