C# CefSharp 根据输入日期段自动选择日期

前言

搞这个Demo整整搞几天通宵，爆肝了。后做的效果出来，还是不错的。给小伙伴看看效果图。

2, 遇到的问题

日期之间相差多少个月数。开始时间框点击对应月份要点击多少次，结束时间框点击对应月份要点击多少次
Xpath获取问题。找到对应html元素包含那个元素，比如 querySelectorAll('td[class$="view"]')。

C# 代码

日期之间可能出现的情况：

// 第1种：2023-11-1 到 2023-11-1

// 第2种：2023-11-1 到 2023-12-25

// 第3种：2023-11-1 到 2024-1-15

// 第4种：2023-10-29 到 2024-1-15

// 1, 获取到时间
string star_time = StartTime.Text;
string end_time = EndTime.Text;// 2， 点击这个自定义时间 弹出时间框 
var btss = csbrowser.EvaluateScript(chromiumWebBrowser1.GetMainFrame(), Properties.Resources.ClickSelectTime);
csbrowser.WaitBusy(chromiumWebBrowser1, 30, 1000);// 3，  获取弹出时间框 当前时间

Js 代码

1, 获取点击按钮弹出时间框里开始和结束时间，文件GetCustomTime.js

var start_Year_code = document.querySelector("body > div:nth-child(7) > div > div > div > div.cook-picker-panel-container > div > div:nth-child(1) > div > div.cook-picker-header > div > button.cook-picker-year-btn");var start_Year_Month_code = document.querySelector("body > div:nth-child(7) > div > div > div > div.cook-picker-panel-container > div > div:nth-child(1) > div > div.cook-picker-header > div > button.cook-picker-month-btn");var start_Year_Month_Day_code = document.querySelector("body > div:nth-child(7) > div > div > div > div.cook-picker-panel-container > div > div:nth-child(1) > div > div.cook-picker-body > table > tbody > tr:nth-child(3) > td.cook-picker-cell.cook-picker-cell-disabled.cook-picker-cell-in-view.cook-picker-cell-today > div");var result = document.querySelector("body > div:nth-child(7) > div > div > div > div.cook-picker-panel-container > div > div:nth-child(1) > div > div.cook-picker-body").querySelectorAll('td[class$="cook-picker-cell-today"]');if (result != undefined && result.length > 0) {//alert(result[0].outerText);start_Year_Month_Day_code = result[0];
}var start_Year_Time = start_Year_code != undefined ? start_Year_code.outerText.replace("年", '') : "";
var start_Month_Time = start_Year_Month_code != undefined ? start_Year_Month_code.outerText.replace("月", '') : "";
var start_Day_Time = start_Year_Month_Day_code != undefined ? start_Year_Month_Day_code.outerText : "";var end_Year_code = document.querySelector("body > div:nth-child(7) > div > div > div > div.cook-picker-panel-container > div > div:nth-child(2) > div > div.cook-picker-header > div > button.cook-picker-year-btn");
var end_Year_Month_code = document.querySelector("body > div:nth-child(7) > div > div > div > div.cook-picker-panel-container > div > div:nth-child(2) > div > div.cook-picker-header > div > button.cook-picker-month-btn");var end_Year_Time = end_Year_code != undefined ? end_Year_code.outerText.replace("年", '') : "";
var end_Month_Time = end_Year_Month_code != undefined ? end_Year_Month_code.outerText.replace("月", '') : "";var json = [{"Year_Time": start_Year_Time,"Month_Time": start_Month_Time,"Day_Time": start_Day_Time,"StartOrEnd_Time_Type": "Start_Time"},{"Year_Time": end_Year_Time,"Month_Time": end_Month_Time,"Day_Time": start_Day_Time,"StartOrEnd_Time_Type": "End_Time"},];[JSON.stringify(json)].toString();

2，点击开始时间框的按钮跳转月数，文件ClickStart_Moth_Time.js

var click_name = document.querySelector("body > div:nth-child(7) > div > div > div > div.cook-picker-panel-container > div > div:nth-child(1) > div > div.cook-picker-header > button:nth-child(2)");
if (click_name != undefined) {click_name.click();
}[click_name != undefined ? click_name.innerHTML:"", is_ok_click].toString();

3，点击结束时间框的按钮跳转月数，文件ClickEnd_Moth_Time.js

var click_name = document.querySelector("body > div:nth-child(7) > div > div > div > div.cook-picker-panel-container > div > div:nth-child(2) > div > div.cook-picker-header > button.cook-picker-header-next-btn");
if (click_name != undefined) {click_name.click();
}[click_name != undefined ? click_name.innerHTML:"", is_ok_click].toString();

4，点击开始时间框的按钮跳转月数后，再获取结束时间框里的时间，NewGetEndTime.js

var click_name = document.querySelector("body > div:nth-child(7) > div > div > div > div.cook-picker-panel-container > div > div:nth-child(2) > div > div.cook-picker-header > button.cook-picker-header-next-btn");
if (click_name != undefined) {click_name.click();
}[click_name != undefined ? click_name.innerHTML:"", is_ok_click].toString();
