แก้ไข code jquery template เพิ่มเติม โดยการเพิ่ม method getTmpl: function(tmpl, options, parentItem) เข้าไป เป็น jquery plugin

 ซึ่ง method นี้ดัดแปลง code มาจาก method tmpl: function(tmpl, data, options, parentItem) ครับ  โดยการเพิ่ม  return function(data) { }  เข้าไป

        //
        getTmpl: function(tmpl, options, parentItem) {
            var ret, topLevel = !parentItem;
            if (topLevel) {
                // This is a top-level tmpl call (not from a nested template using {{tmpl}})
                parentItem = topTmplItem;
                tmpl = jQuery.template[tmpl] || jQuery.template(null, tmpl);
                wrappedItems = {}; // Any wrapped items will be rebuilt, since this is top level
            } else if (!tmpl) {
                // The template item is already associated with DOM - this is a refresh.
                // Re-evaluate rendered template for the parentItem
                tmpl = parentItem.tmpl;
                newTmplItems[parentItem.key] = parentItem;
                parentItem.nodes = [];
                if (parentItem.wrapped) {
                    updateWrapped(parentItem, parentItem.wrapped);
                }
                // Rebuild, without creating a new template item
                return jQuery(build(parentItem, null, parentItem.tmpl(jQuery, parentItem)));
            }
            
            if (!tmpl) {
                return []; // Could throw...
            }

            return function(data) { //เพิ่มเติม

                if (typeof data === "function") {
                    data = data.call(parentItem || {});
                }
                if (options && options.wrapped) {
                    updateWrapped(options, options.wrapped);
                }
                ret = jQuery.isArray(data) ?
                        jQuery.map(data, function(dataItem) {
                    return dataItem ? newTmplItem(options, parentItem, tmpl, dataItem) : null;
                }) : [newTmplItem(options, parentItem, tmpl, data)];

                return topLevel ? jQuery(build(parentItem, null, ret)) : ret;
            };
        },

code ของ method tmpl: function(tmpl, data, options, parentItem)

        tmpl: function(tmpl, data, options, parentItem) {

            var ret, topLevel = !parentItem;
            if (topLevel) {
                // This is a top-level tmpl call (not from a nested template using {{tmpl}})
                parentItem = topTmplItem;
                tmpl = jQuery.template[tmpl] || jQuery.template(null, tmpl);
                wrappedItems = {}; // Any wrapped items will be rebuilt, since this is top level
            } else if (!tmpl) {
                // The template item is already associated with DOM - this is a refresh.
                // Re-evaluate rendered template for the parentItem
                tmpl = parentItem.tmpl;
                newTmplItems[parentItem.key] = parentItem;
                parentItem.nodes = [];
                if (parentItem.wrapped) {
                    updateWrapped(parentItem, parentItem.wrapped);
                }
                // Rebuild, without creating a new template item
                return jQuery(build(parentItem, null, parentItem.tmpl(jQuery, parentItem)));
            }
            if (!tmpl) {
                return []; // Could throw...
            }

            if (typeof data === "function") {
                data = data.call(parentItem || {});
            }
            if (options && options.wrapped) {

        },
