Question

I have one function :

jQuery('#'+'linkhere').click(getHashPageClick);

and in the function I am retreving window.location.hash value :

var getHashPageClick = function(evt) {
    var hashParam =  window.location.hash.substring(1);
}

But now I want to send a parameter to getHashPageClick(), say value , append hashParam value to it and access it in my calling function ? So something like this, maybe? :

jQuery('#'+'linkhere').click(getHashPageClick(value);
 alert("value");

and in the called function modify value of value :

    var getHashPageClick = function(evt,value) {
        var hashParam =  window.location.hash.substring(1);
        valuevalue+hashParam;
return value;

}

Would that be acceptable, or is there a different way to send a parameter by reference so that it is accessible in the calling function and modified value should be reflected ? Because this way doesn’t seem right to me. Any help would be appreciated. Thanks.

Here’s how I would go about setting up the functionality you’re looking for:

jQuery(document).ready(function(){
     var value = 'some value';
     jQuery('#linkhere').click(function(){
          value = getHashPageClick(value);
          alert('the value is now: '+value);
     });
});

var getHashPageClick(value) {
        var hashParam =  window.location.hash.substring(1);
        value = value+hashParam;
        return value;
}

Or, if you don’t want to bump heads with just the one ‘value’ variable, create two variables to work in tandem:

jQuery(document).ready(function(){
     var value = 'some value';
     jQuery('#linkhere').click(function(){
          hashValue = getHashPageClick(value);
          alert('the hash value is now: '+hashValue);
     });
});

var getHashPageClick(value) {
        var hashParam =  window.location.hash.substring(1);
        var hashValue = value+hashParam;
        return hashValue;
}

Hope this helps.
