我在五行中有10个下拉列表选择字段！如果有人从第一个或第二个选择中选择了某个内容，那么我想禁用 同一行中的另一个（不要只消失禁用）！
当我选择启用值时，应启用禁用选择！
对不起我的英文，我希望你理解我的问题！ 提前谢谢!!

您可以使用此代码段：
$('select').change(function(){
$(this).closest('tr').find('select').not(this).prop('disabled', this.value !== "enable")
});
答案 1 :(得分：1)
这会有所帮助：
$("select").on("change", function(){
$(this).closest("td").siblings("td").find("select").attr("disabled",true);
if($(this).val()=="enable") {
$(this).closest("td").siblings("td").find("select").attr("disabled",false);
}
});
答案 2 :(得分：0)
$('select').change(function() {
if($(this).val()!='enable') {
$(this).parent().siblings().children('select').prop('disabled',true);
}
else {
$(this).parent().siblings().children('select').prop('disabled',false);
}
});

我认为这就是答案，你在寻找什么。我想你可以 简化更多。但无论如何你都有了这个主意。

var items = $('#myTable select').on('change', function() {
var index = items.index(this);
var selectArray = $('select');
if(index === 0 || index === 2 || index === 4 || index === 6 || index === 8) {
