14 Common Misconceptions About javascript sanitize string
I have written before on the effects of javascript sanitizing strings and how it can negatively affect your website’s security. So this is not just a rant about the dangers of sanitizing strings, but something I believe is worth reading.
We will discuss this in more detail in chapter 3, but I feel you can find some of the best suggestions here.
Javascript sanitization is a technique that affects both the HTML and JavaScript code in your website. It is the process of removing any strings that contain HTML characters (such as quotes or tags) from your code. It does not remove the tags in your code, but it does remove the references to them, so when the JavaScript code is downloaded the browser is no longer able to interpret that. One way to prevent this is to use a data-* attribute.
If you are going to use the sanitization feature, make sure that you have a data- attribute for every tag in your code. A tag is a sequence of characters (such as a tag) and when you put a data- attribute on it it gets a special attribute that can be used to specify what type of string should be injected into the code. <br/>
The only data- attribute in the code is the name of the tag in question.
It turns out that the browser is no longer able to interpret that. One way to prevent this is to use a data- attribute. If you are going to use the sanitization feature, make sure that you have a data- attribute for every tag in your code. A tag is a sequence of characters such as a tag and when you put a data- attribute on it it gets a special attribute that can be used to specify what type of string should be injected into the code.
The sanitization feature is one of the most important things we’re doing in JavaScript. Another is to use an object that supports the function sanitize-string and add it to our list of object properties. This string sanitization function is not the same as the one we talked about last week. It applies a regular expression to a string and then sanitizes the string.
The string sanitization function is called sanitize-string in the context of the string passed to it. The regular expresion is: /^(.*?)[\s;]/i. The \s; means that the following character should not be included in the string, and the.* is an expression that matches any character except newlines.
The word “si” means that the following character should not be included in the string.
It also means that a string can be shorter than the regular expression and still pass through sanitizing. So if the expression is: “foo bar” the string will be: “foo bar”.
