Question

我有两个选择输入，我用几年的数组填充它们。之后我想为每个Select设置currentYear所选的值。我有这个代码，但只适用于第一选择我不明白为什么。

jQuery 1.4.3的一切都很好用，1.4.2失败了：_（

修改

我正在尝试这个没有成功:-(只有fisrt选择了值好。可能是版本中的问题？IE6，asp.net 2.0，jquery 1.4.2。例如，“$（sinceComboSelector）.val（ currentYear）;“不起作用我必须做”$（'＃cmbAnyDesde选项[value ='+ currentYear +']'）。attr（'selected'，'selected'）;“： - （

我在这里测试过，使用上面的代码，然后工作：

$(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);
};

如何将选择的值设置为多个使用jQuery选择输入？
