batch

Q: 脚本当前路径

%~dp0

Q：用tee重定向

cmd 2>&1 | "C:\Program Files\Git\usr\bin\tee" pyDownload.log

python

使用wget模块下载网页

def download(url, file):
    cmd = 'python -m wget %s -o "%s"'%(url, file)
    #my_system(cmd)
    ret = subprocess.run(cmd, timeout=8).returncode
    print(' %s return %d'%(cmd, ret))
    if ret != 0:
        raise  'error, %s return %d'%(cmd, ret)

获取a和b中间的字符串

def getStrIn(cont, a, b):
    p1 = cont.find(a)
    p1 = p1 + len(a)
    
    p2 = cont.find(b, p1)
    name=cont[p1:p2]
    return name

异常处理

try:
    xxx
except:
    print("Unexpected error:", sys.exc_info()[0])

发送json数据

    try:
        response = requests.post('http://www.hzcourse.com/web/refbook/queryAllChapterList', data={'ebookId':ebookId,'token':token})
        resp_json = response.json()
    except:
        print("Unexpected error:", sys.exc_info()[0])

selenium

Q: click（）函数有时候会hang怎么办？

A:不知道

Q: get()函数有时候会hang怎么办？

A:没有好办法。 一般是因为网页加载未完成。如果你觉得已经ok了，点一下浏览器的停止按钮就可以

打开网页

from selenium import webdriver
driver = webdriver.Chrome()
driver.get('http://ebooks.cmanuf.com/all?id=1&type=2&code=AC05')

通过css selector获取网页内容

book = driver.find_element_by_css_selector('#booklist > dd:nth-child(%d) > a'%(i+1))
book_href = book.get_attribute('href')
book_text = book.text

tampermonkey

header模板

// ==UserScript==
// @name         TimeBooking
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  try to take over the world!

(function() {
    'use strict';
    
})();

xpath用法模板

        var xpath='//textarea';
        var tags_data_image =document.evaluate(xpath, document, null, XPathResult.ANY_TYPE,null);

        var textareavalue='';
        var tags=[];
        for(var tag=tags_data_image.iterateNext(); tag; tag=tags_data_image.iterateNext())
        {
            tags.push(tag);
            if(tag.value.length>0) {
                textareavalue = tag.value;

            }
        }


function _x(STR_XPATH) {
    var xresult = document.evaluate(STR_XPATH, document, null, XPathResult.ANY_TYPE, null);
    var xnodes = [];
    var xres;
    while (xres = xresult.iterateNext()) {
        xnodes.push(xres);
    }

    return xnodes;
}

$(_x('/html/.//div[@id="text"]')).attr('id', 'modified-text');

Logging

console.log(...)

current url

var currentLocation = window.location;

currentLocation.host

Find substring

s.indexOf('citibank')

JSON to string

var sFinal = {"value1":s2, "value2":today};
alert(JSON.stringify(sFinal));

send JSON request

        GM_xmlhttpRequest ( {
            method:     "POST",
            url:        'https://maker.ifttt.com/trigger/bankmoney/with/key/feQcXd0QuePnJb23E97bv',
            data:       JSON.stringify(sFinal),
            headers:    {
                "Content-Type": "application/json"
            },
            onload:     function (response) {
                console.log ("gut response " + response);
                alert("Success " + response);
            }
        } );

insert a node after a node

    function insertAfter(newElement,targetElement) {
        //target is what you want it to go after. Look for this elements parent.
        var parent = targetElement.parentNode;

        //if the parents lastchild is the targetElement...
        if(parent.lastchild == targetElement) {
            //add the newElement after the target element.
            parent.appendChild(newElement);
        } else {
            // else the target has siblings, insert the new element between the target and it's next sibling.
            parent.insertBefore(newElement, targetElement.nextSibling);
        }
    }

create a html node

        var btn = document.createElement("a");
        btn.innerText='DoMyTask!';
        btn.addEventListener("click",updateAll);
        btn.setAttribute('color','red');

stop on debugger

 debugger;

when windoes loaded, call a function

    window.addEventListener('load', function() {
          var checkExist = setInterval(function() {
            if (getRefObject()!=null) {
                console.log("Exists!");
                main();
                clearInterval(checkExist);
            }
        }, 1000); // check every 100ms
    }, false);

css selector

       var matches = document.querySelectorAll(".adaver_box, #div-ad-top, #adHeaderTop, #adFlashLink, *[id^='adRectangle'], #adTextLink, *[id^='divSkyscraper'], *[id^='div-ad-'], *[id^='google_ads'], .anv-ad-content");
        matches.forEach(function(element){
            element.parentNode.removeChild(element);
        });

Use jquery

// @require      http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js

$('a[onmousedown^="return rwt("]').removeAttr('onmousedown');

$('li.action-menu-item.ab_dropdownitem a[href^="http://webcache.googleusercontent."]').each(
            function() {
                $(this).closest('div.action-menu.ab_ctl').after(' ').after($(this))
            }
        )
