下面示例说明了 big 方法是如何工作的：



var strVariable = "This is a string object"

strVariable = strVariable.big( )

在执行完最后一个语句后，strVariable 的值为：



<BIG>This is a string object</BIG>

不检查该标记是否已经被应用于该字符串

-The following example shows how big is the work: var strVariable = " This is a string object"　 strVariable = strVariable.big ()　in the implementation of completed after the last statement, strVariable value: <BIG>This is a string object</big> does not check whether the mark has been applied to the string
