我想问下，这个地方我要用判断，应该怎么写呀！html

sharedata = {
title :{if $activityInfo['yaoqing'] == 1}"{$userInfo['nickname']}" + ' 邀您参加 ' + '{$activityInfo["sharetitle"]}'{else if $activityInfo['yaoqing'] == 0}'{$activityInfo["sharetitle"]}'{/if},

        link   : '{$shareURL}',
        desc   : '{$activityInfo["sharedsc"]}',
        imgUrl : '{php echo tomedia($activityInfo["shareImg"])}',
        success: function(){
            //alert('success');
            console.log('success');
        }
    };

使用三元表达式

sharedata = {
  title: $activityInfo['yaoqing'] == 1 ? 'xxxx1' : 'xxxxx2'
}
