javascript remove function not valid

Question

I'm trying to debug this function in Firefox/Firebug and it says that "dbasedata.remove" is not a function??

function dbasetype(){

var dbasedata = document.forms[0]._dbase_name.value;
        dbasedata = dbasedata.toUpperCase();
        dbasedata = dbasedata.replace(/\s/g, "");
        dbasedata = dbasedata.remove("UK_CONTACTS","");

if (dbasedata != "") {
        _area.value = _dbase_name.value;            
    } }

Firebug is correct. There is no such method. You probably want replace(). — JJJ

I agree with Firebug, what are you trying to accomplish with 'dbasedata.remove("UK_CONTACTS","")' ? — ClydeFrog

dbasedata contains the value of the object _dbase_name. Do you want to remove the object or edit it's value? — Peter Rasmussen

I want to remove UK_CONTACTS from the string so I can test if there is any data left in the string. — labman

Use replace(). If you replace something with an empty string it's effectively removing it. Or if all you want is to check if it has some specific value, just test for it directly: if( dbasedata == "UK_CONTACTS" ) ... — JJJ

It's because JavaScript strings have no such method as remove().

You can see the available methods here.

If you want to replace "UK_CONTACTS" with "" then see the replace() method instead:

dbasedata = dbasedata.replace("UK_CONTACTS","");

Use

dbasedata = dbasedata.replace(/UK_CONTACTS/, "");

instead.

A string object does not have a Remove() function. Firebug is correct. You might want to use replace() instead:

function dbasetype(){

var dbasedata = document.forms[0]._dbase_name.value;
        dbasedata = dbasedata.toUpperCase();
        dbasedata = dbasedata.replace(/\s/g, "");
        dbasedata = dbasedata.replace("UK_CONTACTS","");

if (dbasedata != "") {
        _area.value = _dbase_name.value;            
    } }
