When using Baidu Google, we will find that as long as we enter a word, there will be relevant prompts. This has greatly improved the experience of the website. Now I will learn with you a php+mysql+ajax imitation Baidu Google search. Example of drop-down automatic prompt box effect.
I wrote it a long time ago, and now I have a blog to share with you. The principle of imitating Baidu and Google search drop-down automatic prompts is not very complicated, mainly through the ajax bridge. It is not as powerful as Baidu. It can match pinyin and so on. I really can't do it at my current level. I just want to achieve this effect.
Let’s take a look at the source code, there is analysis and source code download at the end
Database, we save it and import it into mysql database
The code is as follows
Copy code
代码如下

These are the core codes, with a complete example download address at the back
Let’s take a look at the effect first (go below, you can download the source code^_^)
The effect after entering a “p”
A match will be made for each character entered
The effect is like this. If you think it is okay, you can download the source code below to play with it.
I have only added about 10 pieces of data to the data table. If necessary, you can add it yourself.
