}


var getBinddingContent=function(temp,data){
    var me=this,
        res='',
        hasNull=false;
    if(temp==null||typeof temp=='undefined'){
            return res;
        }
    res= temp.replace(/\$\{([^\}]+)?\}/g, function($1, $2) { 
        if(data[$2]==null||typeof data[$2]=='undefined'){
            hasNull=true;
        }
        return data[$2]; 
    });
    return hasNull?'':res;

}

var binddingToHtml=function(node,content){
    var me=this;
    if(node.getAttribute('IsDateTime')){
        node.innerText='';//if u want change it to datetime string
        return;
    }
    if(node.getAttribute('AddBr') && content==''){
        node.innerText='';
        var brTag=document.createElement('br');
        node.appendChild(brTag);
        return;
    }
   node.innerText=content;
}

You use the 'tag' by calling:

with data var data={d1:'t1',d2:'t2',d3:'t3'}
