console.log 将显示传递给 log 方法的参数控制台窗口.使用此方法在控制台窗口.
console.log will display the parameter passed to the log method in the console window. Use this method to display a string or variable in the console window.
您也可以在代码中使用控制台类,就像我们一样使用 JavaScript 警报.
You can use the console class in your code as well, much like we can use JavaScript alerts.
<script type = "text/javascript">
function tryConsole() {
console.log("hello world");
}
</script>
当使用return
语句时,函数将停止执行,并返回指定的值.
When using the return
statement, the function will stop executing, and return the specified value.
