prototype chain and the scope chain are taken into account, that is, "two-dimensional chain search ". 4. The independent scope can only be created using functions. the next half of this sentence is -- It cannot be created using statement blocks such as if/. You may know the last half of the sentence, but its essence is indeed the first half-the Independent scope can only be created through functions (except for the independent scope, the rest is the global scope ). Since the independent scope c

The problem with global variables is that both your JavaScript application and all the code on the Web page share these global variables, and they live in the same global namespace, so naming conflicts are unavoidable when two different parts of the program define global variables with the same name but with different effects.The two features of JavaScript, unconsciously creating global variables are surprisingly easy. First, you can use variables without even needing to declare them; second, Ja

Tom continues to seek help .. In PHP, how does one use arrays as conditions for SQL query statements. Thank you for your great help in your previous post and finally figured out what was going on. Now I encountered another problem: I asked the user to submit 12 multi-choice lists on one page, and obtained 12 Arrays. then I searched the database based on the contents of these 12 groups, however, it seems that there is no way to extract the content from

Tom started, This is the first time I began to write a blog to urge myself to learn. I have a certain understanding of python and have written some things, but I have not really learned the system. I am studying what to do, but I still need to enrich myself in the face of graduation. The first thing to do today is: 1. When a user logs on, the user is automatically locked if the user fails to log on three times. 2. Level 3 menu Analysis: The first is v

I have detected injection attacks on Sohu, TOM, and Netease portals, and found that there are also obvious injection vulnerabilities, which are very poor in security. 1. MySQL injection Detection First, let's take a look at Sohu's website. Most of the dynamic web pages on Sohu's website are written in PHP, and there are also a lot of injections. For example: Http://app.sh.sohu.com/lo###l/s.php? Id = 636 This webpage is an l'oreal advertisement pag

Continue Uncle Tom's JS tour.Secret named function expressionsfunction expressions and Function declarationsUncle Tom quoted the ECMA specification in the blog: function declarations must have identifiers, and function expressions can be omitted. For me, the concept of these things really does not fit. Or an example of a big uncle. The example above is as follows:function foo () {};//Ghost knows it's a statement.var bar = function foo () {};//Ghost kn

It has the function of writing code on an online webpage. New students can watch their own code in real time! Well, let's go to the topic. Well, today, I mainly use simple tag usag
