Firefox vs chrome uncaught syntaxerror unexpected token error

What the hell wrong with this function in google chrome, while it is working absolutely perfect in firefox, 

function is_valid(type="") {
    if(type==""){
        return false;
    }

    $.ajax({
        url: "<?=site_url('controller/function')?>"+'/'+type,
        success: function(data){
        }
    });
}

it always gives me a red line error in my firebug console, and breaks all my functionality,

uncaught syntaxerror unexpected token=

I am wondering that, why it is giving me an error, while every thing is perfectly working in firefox, i am using following jquery libraries, 

<script src="path/jquery-1.7.1.js"></script>
<script src="path/jquery-ui-1.8.16.min.js"></script>

EDIT

here i call this, 

<input name="my_type" onblur="is_valid($(this).val());" type="text" class="required />

There may be some characters can say zero-space characters which are not shown, try to delete the code and type again may solve your problem.

Also change your function is_valid like,

function is_valid(type) {// remove assignment of type from here
    if(typeof(type)==='undefined' || !type){
        return false;
    }
    ... remaining code

The method signature is invalid, you can't apply a default value like that

One possible solution is to check whether the value is a falsy value like, it will return of the value of type is undefined, '', 0, NULL, etc

function is_valid(type) {
    if(!type){
        return false;
    }

    $.ajax({
        url: "<?=site_url('controller/function')?>"+'/'+type,
        success: function(data){
        }
    });
}
