引用窗体控件的简单日期差异

// 获取两个日期输入框的值
var startDate = new Date(document.getElementById("startDate").value);
var endDate = new Date(document.getElementById("endDate").value);

// 计算日期差异
var timeDiff = Math.abs(endDate.getTime() - startDate.getTime());

// 计算天数差异
var daysDiff = Math.ceil(timeDiff / (1000 * 3600 * 24));

// 输出结果
console.log("日期差异（天数）：" + daysDiff);

from flask import Flask, request

app = Flask(__name__)

@app.route("/date-diff", methods=["POST"])
def date_diff():
    start_date = request.form.get("start_date")
    end_date = request.form.get("end_date")

    # 计算日期差异
    time_diff = abs(end_date - start_date)

    # 计算天数差异
    days_diff = time_diff.days

    # 返回结果
    return str(days_diff)
