要使用可变数量的参数来运行,请使用arguments对象。
您可以尝试运行以下代码以在JavaScript中实现函数的参数
<html> <body> <script> function functionArgument(val1, val2, val3) { var res = ""; res += "Expected Arguments: " + functionArgument.length; res += "<br />"; res += "Current Arguments : " + arguments.length; res += "<br />"; res += "Each argument = " for (p = 0; p < arguments.length; p++) { res += "<br />"; res += functionArgument.arguments[p]; res += " "; } document.write(res); } functionArgument(20, 50, 80, "演示文字!","Hello World", new Date()) </script> </body> </html>
