checkbox赋值，多个值默认选中

function checkboxSelectFn(typeStr,name){
              var cbArray = new Array;  
            cbArray = typeStr.split(",");  
             var str=document.getElementsByName(name);  
               var objarray=str.length;  
                for(i=0;i<cbArray.length;i++){  
                   for (j=0;j<objarray;j++){  
                         if(str[j].value == cbArray[i]){  
                            str[j].checked = true;  
                         }  
                   }  
                  }
           }

调用checkboxSelectFn(all_Model,"test1");

all_Model=“11,22,33,44”

<c:forEach var="models" items="${models}">
         <p><input type='checkbox' name='test1'  value='${models.modelName}'>${models.modelName}</input></p>
</c:forEach>
