    {
        if (this.config.editorEnabled) {
            return '<div id="aitcg-control-panel">' +
                '<button onclick="return setproductlogin(\'<?php echo Mage::registry("current_product")->getId()?>\', event);setrequestlogin();" id="submit-editorApply-{{rand}}" >Create</button>' +

<script>

<?php if($customerId){?>

            return '<div id="aitcg-control-panel">' +
                '<button onclick="return setproductlogin(\'<?php echo Mage::registry("current_product")->getId()?>\', event);setrequestlogin();" id="submit-editorApply-{{rand}}" >Create</button>' +
                '</div>';
        }
        return '';
    },

<?php }else{?>

_getControlPanelHtml: function()
    {
        if (this.config.editorEnabled) {
            return '<div id="aitcg-control-panel">' +
                '<button onclick=" setproductlogin('<?php echo $_product->getEntityId()?>');setrequestlogin();" id="submit-editorApply-{{rand}}" >Create</button>' +
                '</div>';
        }
        return '';
    },

    <?php }?>

Answer 1

Replacing below code :

onclick="setproductlogin('<?php echo $_product->getEntityId()?>');setrequestlogin();"

by below code solved issue :

onclick="return setproductlogin(\'<?php echo Mage::registry("current_product")->getId()?>\', event);setrequestlogin();"
