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

1. 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
2. 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

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();
