How to check if an item is selected from an HTML drop down list?

Question

I have a drop drown list and I am having trouble checking whether or not a value has been selected from the drop down list Below is my HTML Code : ``` Card Type:
``` Below is my JavaScript Code : ``` var card = document.getElementByName("cards")[0].value; if (card.value == selectcard) { alert("Please select a card type"); } ```

Accepted Answer

Well you missed quotation mark around your string `selectcard` it should be `"selectcard"`

```
if (card.value == selectcard)
```

should be

```
if (card.value == "selectcard")
```

Here is complete code for that

```
function validate()
{
 var ddl = document.getElementById("cardtype");
 var selectedValue = ddl.options[ddl.selectedIndex].value;
    if (selectedValue == "selectcard")
   {
    alert("Please select a card type");
   }
}
```
