You can do almost invoke on MySQL through the javascript API in browser.
The client javascript api support IE6.0+ Chrome FireFox and Wechat

-
Rapid prototyping does not need to write server-side code.
-
Academic teaching and research, WYSIWYG
-
Enterprise internal application
-
Other applications that do not focus on the security of the database table structure.
- Run MySQL first.
- Put webmysql.war in your servlet server webapps ,Apache Tomcat8.0 , Glass Fish Server4.x and so on.
- Open browser(Chrome FireFox IE) and put http://localhost:8080/webmysql/, The address may be different depending on your settings
-
Copy Statement.java and StatementServlet.java from webmysql.war /src/java/.. , into your src/java/org/dbcloud/mysql
-
Copy all *.js files in webmysql.war /js to your js directory. JQuery is necessary. IE6.0 need to use the 1.x version and json2.js is necessary.
-
Edit the web.xml, like this:
<servlet>
<servlet-name>MySQLStatement</servlet-name>
<servlet-class>org.dbcloud.mysql.StatementServlet</servlet-class>
<init-param>
<param-name>guid</param-name>
<param-value>class</param-value>
</init-param>
<init-param>
<param-name>driver</param-name>
<param-value>com.mysql.jdbc.Driver</param-value>
</init-param>
<init-param>
<param-name>connection</param-name>
<param-value>jdbc:mysql://localhost:3306/yourdbname?useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=false</param-value>
</init-param>
<init-param>
<param-name>user</param-name>
<param-value>test</param-value>
</init-param>
<init-param>
<param-name>password</param-name>
<param-value>test</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>MySQLStatement</servlet-name>
<url-pattern>/org.dbcloud.mysql.Statement</url-pattern>
