Recently, the company is busy and has no time to post some blog posts. Recently, because the project needs a large screen to display maps, most of the large screens use dark blue base maps. At present, the sky map does not provide dark blue tiles. The built-in JS API only supports black and indigo, but the project requires the use of the sky map. The search engine has found solutions in various ways. Finally, it decided to use CSS filters to solve this problem, and recorded the solutions in the blog.

First, I want to talk about why I want to go to the interview, because I talked with the seniors during dinner. It's a good opportunity to find a summer internship in my junior year, and the awards I won in school are all around the front. As a person who wants to know what level he is at, he must invest in a big factory, so he chose Alibaba's front-end development. On March 19, Alibaba's boss pushed his resume to the campus recruitment system.

For the purpose of learning and communication, use trembling fingers to enter the following code in the user name input box:< script> alert(1)</ script> emm... No response, a burst of loss in the heart, did not expect to pop up a box, sighed. However, it is a program ape, and you can't give up easily. I found some xss variant codes to test:&lt/ textarea>& lt; img onerror="alert(1)" src='1'> WO...

At present, there are many problems in many schools, such as educational outsourcing, poor skills of operation and maintenance personnel, and few server resources, so the general educational administration system will not be exposed in the Internet. However, I have to study how to penetrate the intranet due to the rigid need of score query and curriculum query.

Recently, when I visited blogs, I found that many blogs have the reward function. Although there may be few people to reward, it is always a kind intention to let bloggers know that their articles are useful and can help people. So I also want to add a reward function~

This article is a summary of my own. Therefore, the course is for beginners and has no technical content. The python environment is basically available in Linux, and the official website under Windows also provides convenient installation packages. There are many online tutorials on how to install and configure. The Python version I use is Python 3.6.4, and the following code is also based on Python 3.

Presumably, many people will write a few or even dozens of lines of code to make it list all the files into an array for deletion, but the glob function solves the problem in minutes! Example 1 {Code...} Output similar: {Code...} Example 2 {Code...} Output similar: {Code...} Delete all files in the directory {Code...}

Test URL: [link] {Code...} {Code...} {Code...} {Code...} {Code...} {Code...} {Code...} {Code...}

In fact, this problem has nothing to do with the language used to export csv files. When Excel displays numbers, if the number is greater than 12 digits, it will automatically be converted into scientific counting method; If the number is greater than 15 digits, the number after 15 digits will be displayed as 0 due to the precision limit.

When a click event is added to an element by delegation, if the event is delegated to the document or body, and the delegated element is not clickable by default (such as div, span, etc.), the click event will become invalid.

It suddenly occurred to me today that the statistics function was not added to Api's timetable query, so I added statistics today, recording the type, event and time of the request, which can be used when the new semester comes. After all, students who just started school still care about what classes are available this semester, and can also enrich the content of the curriculum product page. But it's no use just counting to the database, right? At least add the total number of times to obtain each request type, so as to display

Interpretation: Wanguo Code, without transcoding and risk of garbled code, saves space. utf8mb4 is a superset of utf8. Due to the increase of mobile devices in recent years, emoji expressions and some uncommon Chinese characters will appear garbled code under utf8, so it needs to be upgraded to utf8mb4

First, let's briefly introduce the Textbook Curriculum: WXML, WXSS and JS based on the MINA framework of WeChat applet are developed in code language, the view layer adopts Flex elastic layout, and the logic layer adopts modular development mode. More than 1000 users have been released in a week. Official WeChat official accounts such as School of Literature and Economics of Yantai University, Student Union of School of Literature and Economics of Yantai University and other official WeChat official accounts are actively associated with small programs. More information: [link]. Why should I talk about the implementation method of this interface separately? In fact, this is the same as the lesson
