如果选择选项空,然后选择选项3
原标题:if select option blank, then select option 3

提前感谢你们为这次行动提供帮助的任何人。

我们有一个下降 与空白选项 在第一个。

<select id="Flags">
<option></option>
<option value="Corporate">Corporate.png</option>
<option value="Store2">Store2.png</option>
</select>

如果选中第一个空白选项, 我如何才能删除它, 并选择“ store2 ”?

If $( #Flags option[value=""] )
Then .remove();
and $( #Flags ).val ("Store2")

非常感谢你们的帮助

问题回答

尝试此 :

$("#Flags").change(function() {
    if (!$(this).val()) 
        $(this).val("Store2");
});

最好将 Store2 设为默认,而不是空白选项,因为如果用户选择空白项目,您可能会混淆他们的用户,但请看所选的 Store2.png 。
