我有两个选择输入框,我用年份数组填充它们。之后,我想将currentYear设置为每个Select的选定值。我有这段代码,但只适用于第一个Select,我不明白为什么。
在jQuery 1.4.3中一切都很好,而1.4.2失败了:_(
我正在尝试这个,但没有成功:-(只有第一个选择框的选定值是正确的。版本可能存在问题吗?IE6,asp.net 2.0,jquery 1.4.2。例如,"$(sinceComboSelector).val(currentYear);"不起作用,我必须执行"$ ('#cmbAnyDesde option [value =' + currentYear + ']'). attr('selected','selected');" :-(
代码已更新:

if ($('#cmbAnyHasta)) {
总是会通过。请使用$('#cmbAnyHasta').length
代替。 - lonesomeday
