With the development of the Internet, search has become one of the main ways we obtain information online. As more and more websites use dynamic interactive methods to display information, JavaScript search functions are becoming more and more important. Here are some key points to note when implementing JavaScript search functionality.
Rendering Speed
Searching is one of the most common actions users perform on a website. Therefore, search needs to respond quickly, otherwise the user experience will be greatly affected. Rendering speed is one of the keys to JavaScript search capabilities. To increase rendering speed, you can use the following techniques:
- Compress JavaScript code. This can reduce code size and increase download speed.
- Cache search results. This avoids recalculating results on every search, improving responsiveness.
- Front-end rendering. If search results are loaded asynchronously via Ajax, you can use front-end rendering to improve responsiveness.
User Experience
The purpose of the JavaScript search function is to help users quickly find the information they need. Therefore, a good user experience is crucial. Here are some points to note when implementing a good user experience.
- automatic completion. When users start entering search keywords, you can provide auto-complete prompts so that users can find relevant content more quickly.
- Real-time search. When users enter keywords, matching search results can be displayed in real time to reduce user waiting time and page turning operations.
- Provides filtering options. Provide filtering options in search results to help users find and filter out the information they need more easily.
- Keep search history. Saving a user's search history can help users more easily access content they've already searched for and increase the likelihood that users will return.
Search Accuracy
Correctly matching search requests is the ultimate goal of JavaScript search functionality. Here are the key points to note when achieving search accuracy.
- Search algorithm. Choosing the right search algorithm (such as an inverted index) can help improve search accuracy.
- search for the keyword. In order to improve the accuracy of the search, you need to ensure that the search keywords exactly match the target text, or at least contain keywords that are similar to the target text.
- Ignore case and punctuation. To avoid inaccurate searches, you can ignore case and punctuation.
- Support fuzzy search. Sometimes, users may enter incomplete or incorrect search keywords. Supporting fuzzy search can help users find relevant content.
JavaScript search functionality has become an important part of modern websites. When implementing the search function, you need to follow the above key points to provide a good search experience and accurate search results.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
