所以我有这个日期选择器，它必须帮助用户选择一个日期。我无法让它识别以某种方式写成的月份，例如jan，feb，Feb等。
编辑：我为每个月制作了一个循环，检查两个变量是否都具有月份，并且现在可以正常工作。我想使它与像这样的数组一起工作：
var months = [
{
abbr: 'Jan',
name: 'January'
}];
所以我也可以使用全名。我会尝试自己创建全名，然后将结果发布在这里。
编辑的Datepicker jQuery：
(function ($) {
//date autocomplete
var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];

inputLength = date.val().length;
if (inputLength > 3) {
value = $(this).val();
value = value.replace(new RegExp("/\|\-|\,|\\s|//", "g"), '.');
value1 = value.split('.')[1];
value2 = value.substr(0, value.indexOf('.'));

我为此做了很多工作，所以我不想做已经完成的事情，但是我无法弄清这里缺少什么，我将非常感谢您的帮助。
