我有2个选择输入，并用一系列年份填充它们。之后，我想为每个Select设置currentYear选定的值。我拥有此代码，但仅适用于第一个Select，但我不明白为什么。

一切都适用于jQuery 1.4.3，1.4.2失败:_(

我正在尝试不成功:-(只有fisrt才选择了OK值。在版本中可能有问题吗？IE6，asp.net 2.0，jquery 1.4.2。例如，“$(sinceComboSelector).val(currentYear); “不起作用，我必须要做一个” $('＃cmbAnyDesde option [value ='+ currentYear +']')。attr('selected'，'selected');“:-(

最佳答案
我在这里使用上面的代码进行了测试，并且可以正常工作:
$(document).ready(function (){
loadYears();
});
var loadYears = function () {
var currentYear = new Date().getFullYear(),
years = [],
firstYear = currentYear - 7,
lastYear = currentYear + 3,
sinceComboSelector = "#cmbAnyDesde",
toComboSelector = "#cmbAnyHasta",
i;
for (i = firstYear; i <= lastYear; i++){
years.push(i);
}
$(sinceComboSelector).find('option').remove();
$(toComboSelector).find('option').remove();
$.each(years, function(key, value) {
$(sinceComboSelector)
.append($("<option></option>")
.attr("value", value)
.text(value));
$(toComboSelector)
.append($("<option></option>")
.attr("value", value)
.text(value)); ;
});
$(sinceComboSelector).val(currentYear);
$(toComboSelector).val(currentYear);
};
