debugger 语句调用任何可用的调试功能，例如设置断点。 如果没有调试功能可用，则此语句不起作用。

+ +

语法

+ +
debugger;
+
+ +

示例

+ +

下面的例子演示了一个包含 debugger 语句的函数，当函数被调用时，会尝试调用一个可用的调试器进行调试。

+ +
function potentiallyBuggyCode() {
+    debugger;
+    // do potentially buggy stuff to examine, step through, etc.
+}
+ +

当 debugger 被调用时, 执行暂停在 debugger 语句的位置。就像在脚本源代码中的断点一样。

+ +

Paused at a debugger statement.
