How to get the months between 2 dates
提问by Slim
I'm using jquery datepickerin order to get 2 dates. In my case I have to get the date in this format d-M-y. I'm using it in order to be able to insert the values into an oracledatabase without any formating. The problem is that I need to calculate the months between 2 dates. For example: 1-Oct-13- 30-Oct-16.
我正在使用 jquerydatepicker来获取 2 个日期。就我而言，我必须以这种格式获取日期d-M-y。我使用它是为了能够在oracle不进行任何格式化的情况下将值插入到数据库中。问题是我需要计算两个日期之间的月份。例如：1-Oct-13- 30-Oct-16。
Here is how I'm getting the dates in my js:
这是我如何在我的 js 中获取日期：
LastAssimDatePicker = (function() {
$( "#lastAssimilationDate" ).datepicker({
yearRange: "-20:+100",
changeMonth: true,
changeYear: true,
dateFormat: "d-M-y"
});
}),
LastAssimDateOverPicker = (function() {
$( "#lastAssimilationDateOver" ).datepicker({
yearRange: "-20:+100",
changeMonth: true,
changeYear: true,
dateFormat: "d-M-y"
});
}),
The above dates are assigned to 2 variables- lastAssimilationDateand LastAssimDateOver
上述日期分配给2 variables-lastAssimilationDate和LastAssimDateOver
The problem is that I really can't find a way to calculate the months between the 2 dates and I already lost about 2 hours on it. I'm pretty sure that there will be an easy solution, but as a beginner, I'm not able to spot it. I know that there are simmilar topics here, but I can't get it working, or it does not fit on my issue.
问题是我真的找不到计算两个日期之间的月份的方法，而且我已经浪费了大约 2 个小时。我很确定会有一个简单的解决方案，但作为初学者，我无法发现它。我知道这里有类似的主题，但我无法让它工作，或者它不适合我的问题。

function monthDiff(d1, d2) {

function calcualteMonthYr(){
var fromDate =new Date($('#txtFrom').val()); //datepicker (text fields)
var toDate = new Date($('#txtTo').val()); // datepicker
var months;
months = (toDate.getFullYear() - fromDate.getFullYear()) * 12;
months += toDate.getMonth();
if (toDate.getDate() < fromDate.getDate())
{
months--;
}
$('#txtTimePeriod2').val(months);
}
// it also consider dates so you would get exact months ..
