You can log variables and so on in the console.
您可以在控制台中记录变量等。
e.g.:
例如:
console.log(get_parestotal);
You can even concatenate witht he use of +console.log('This is your variable'+get_parestotal)
您甚至可以使用+console.log('This is your variable'+get_parestotal) 进行连接
You can even add styling to your log (color, background-color,...):
您甚至可以为日志添加样式(颜色、背景颜色……):
console.log('%cThis is your variable'+get_parestotal+'!','color:green;');
There are some alternatives to console.log() you could use:
您可以使用 console.log() 的一些替代方法:
console.warn();
console.info();
console.error();
console.debug();

You can either do alert(myvar)or console.log(myvar).
您可以执行alert(myvar)或console.log(myvar)。
Caveat: console.log is only supported in certain browsers...see the link.
警告:console.log 仅在某些浏览器中受支持...请参阅链接。
