我尝试过：

i have a switch with multiple cases and getting the result as given in below code ,is there a shorter way or a better way for this

What I have tried:

var selectedCase=false;
             var selectedItem='';
            var item = ui.item;
              switch(item.type)
           {
               case 'brands':
               selectedCase=true;
               selectedItem= base_url+'brand/'+item.BrandUniqueName;
               searchHeader.saveResult(selectedItem);
               window.location.href = base_url+'brand/'+item.BrandUniqueName;

               break;
               case 'categories':
               selectedCase=true;
               selectedItem= base_url+'categories/'+item.CategoryUniquename;
               searchHeader.saveResult(selectedItem);
               window.location.href = base_url+'categories/'+item.CategoryUniquename;

               break;
               case "categoryBrand":
               selectedCase=true;
               selectedItem= base_url+'brand/'+item.BrandUniqueName+'?category='+item.CategoryUniquename;
               searchHeader.saveResult(selectedItem);
               window.location.href = base_url+'brand/'+item.BrandUniqueName+'?category='+item.CategoryUniquename;

               break;
               case 'offercategory':
               selectedCase=true;
               selectedItem=  base_url+'offercategory/'+item.OfferCategory;
               searchHeader.saveResult(selectedItem);
               window.location.href = base_url+'offercategory/'+item.OfferCategory;

               break;
               case 'vendorOfferCategory':
               selectedCase=true;
               selectedItem=base_url+'offers/'+item.UniqueName+'?category='+item.OfferCategory;
               searchHeader.saveResult(selectedItem);
               window.location.href = base_url+'offers/'+item.UniqueName+'?category='+item.OfferCategory;

               break;
               case 'vendor':
               selectedCase=true;
               selectedItem= base_url+'offers/'+item.VendorUniqueName;
               searchHeader.saveResult(selectedItem);
               window.location.href = base_url+'offers/'+item.VendorUniqueName;

               break;
               case 'offers':
               selectedCase=true;
               selectedItem= base_url+'offers/'+item.UniqueName;
               searchHeader.saveResult(selectedItem);
                window.location.href = base_url+'offers/'+item.UniqueName;

               break;
               case 'vendorcategory':
               selectedCase=true;
               selectedItem= base_url+'topcategories/'+item.UniqueName;
               searchHeader.saveResult(selectedItem);
               window.location.href = base_url+'topcategories/'+item.UniqueName;

               break;
               case 'vendors':
               selectedCase=true;
               selectedItem= base_url+'offers/'+item.UniqueName;
               searchHeader.saveResult(selectedItem);
               window.location.href = base_url+'offers/'+item.UniqueName;

               break;
               case 'products':
               selectedCase=true;
               selectedItem= base_url+'products/'+item.InternalLink;
               searchHeader.saveResult(selectedItem);
               window.location.href = base_url+'products/'+item.InternalLink;

               break;
               case "Not Available":
               //$("#autocomplete").val('');
               break;

           }

推荐答案

（＃autocomplete）。val（''）;
休息;

}

("#autocomplete").val(''); break; }

您可以重新组织数据，以便在切换之前设置一个值，只修改它必要时（也可能）。



例如：

You can reorganize your data so that you set a value prior to the switch and only modify it when necessary (and possible).

Eg:

selectedCase=true;

你可以把它放在开关外面，只在开关时修改它

You can put that outside the switch and only modify it in the switch when

selectedCase=false;

删除交换机中的任何内容（循环，无论如何），它们也保持不变。只告诉电脑一次！

Remove anything in your switch (loop, whatever) that either remains unchanged, as well. Tell the computer just once!
