Changing various id's after cloning in jquery

Question

I\'m trying to clone a table row and update the multiple id\'s to reflect the input fields. I start by doing this and it works:

$(id).clone().attr(\"id\", \"

I have created a generalised solution. The function below will change ids and names of cloned object. In most cases, you will need the row number so Just add "data-row-id" attribute to the object.

function renameCloneIdsAndNames( objClone ) {

    if( !objClone.attr( 'data-row-id' ) ) {
        console.error( 'Cloned object must have \'data-row-id\' attribute.' );
    }

    if( objClone.attr( 'id' ) ) {
        objClone.attr( 'id', objClone.attr( 'id' ).replace( /\d+$/, function( strId ) { return parseInt( strId ) + 1; } ) );
    }

    objClone.attr( 'data-row-id', objClone.attr( 'data-row-id' ).replace( /\d+$/, function( strId ) { return parseInt( strId ) + 1; } ) );

    objClone.find( '[id]' ).each( function() {

        var strNewId = $( this ).attr( 'id' ).replace( /\d+$/, function( strId ) { return parseInt( strId ) + 1; } );

        $( this ).attr( 'id', strNewId );

        if( $( this ).attr( 'name' ) ) {
            var strNewName  = $( this ).attr( 'name' ).replace( /\[\d+\]/g, function( strName ) {
                strName = strName.replace( /[\[\]']+/g, '' );
                var intNumber = parseInt( strName ) + 1;
                return '[' + intNumber + ']'
            } );
            $( this ).attr( 'name', strNewName );
        }
    });

    return objClone;
}
