JavaScript connects mysql and php to any database instance sharing through odbc

javascript mysql odbc

I was so imaginative that I used JavaScript to connect to mysql. It took 2 hours and I finally realized it. I used odbc. Later I thought of using php to connect to odbc to connect to the database. I also realized it, so I will put the case here. This article mainly shares an example of javascript connecting mysql and php to any database through odbc. It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor to take a look, I hope it can help everyone.

Notes:

1. JavaScript uses the "new ActiveXObject" object to connect to mysql. This object is only supported by IE browser, so it can only be connected to mysql under IE browser.

2. JavaScript also connects to MySQL through ODBC. The difference from PHP is that one of the parameters. In the picture, the red one is the PHP connection data source name, and the blue one is the JavaScript connection data source name. , it is very easy to mislead here.

3. Please note when downloading and configuring the odbc source. The VC library must have the same number of bits as the odbc installation file. 32-bit sources correspond to 32-bit or X86VC libraries, and 64-bit sources correspond to 64-bit VC library, and the odbc data source management program is not easy to find. There are two ways. The first is to open the control panel, search for odbc, and select the corresponding version controller to configure. The second is to search for odbcad32 in system32 under Windows. exe is the 64-bit version, syswow64 search odbcad32.exe is the 32-bit version.

#4. If you use it individually, you can configure the user DSN. If you use it multiple times or use it online, you can configure the system DSN.
