it working , displaying list of products. need change css class first record because ad banner. using following if statement:

itemtpl: new ext.xtemplate(                 '<tpl if={isbanner} === true>',                     '<div class="mytestclass">{itemimage}</div>',                  '<tpl elseif={isbanner} === false>',                     '<div class="featureimageholder"><img class="featureimage" src="{itemimage}" alt="{itemname}" /></div>',                 '</tpl>',                   '<span class="item">',                     '<h3 class="salename">{itemname}</h3>',                     '<span class="priceoptions">',                     '<tpl for="prices">',                         '<span class="priceoptionreg">',                             '<tpl if="priceoptiondesc">{priceoptiondesc}</tpl> ',                             '<tpl if="priceoptionreg">{priceoptionreg}</tpl>  ',                             '<tpl if="pricereg">${pricereg}</tpl>  ',                             '<tpl if="priceregsuffix">{priceregsuffix}</tpl> ',                         '</span>',                         '<tpl if="pricesale"><span class="priceoptionsale">',                             '<tpl if="pricesaledesc">{pricesaledesc}</tpl> ',                             '<tpl if="priceoptionsale">{priceoptionsale}</tpl>  ',                             '<tpl if="pricesale">${pricesale}</tpl>',                             '<tpl if="pricesalesuffix">{pricesalesuffix}</tpl> ',                         '</span></tpl>',                     '</tpl>',                     '</span>',                 '</span>',                 '<div class="clear"></div>'             ),

the problem if/elseif both executed each record. if use if/else gives error in console.

uncaught syntaxerror: unexpected token else

you can see have used

'<tpl if={isbanner} === true>',

i have used

'<tpl if={isbanner} == true>',

i have tried many varients comparing numeric values instead of boolean , using &gt; or &lt;. tried comparing string values. variations, if/elseif both executing , if/else gives error.

any appreciated, need change class first record.

if isbanner boolean, work

'<tpl if="isbanner">',      '<div class="mytestclass">{itemimage}</div>', '<tpl else>',      '<div class="featureimageholder"><img class="featureimage" src="{itemimage}" alt="{itemname}" /></div>', '</tpl>',
