使用目的：捕获在特定程序语句中发生的错误。
说明：在try语句中加入可能发生错误的代码，而catch语句则包含用来处理确实发生错误的代码。catch语句需要一个变量参数，它的初始值是发生的错误值。使用try-catch进行错误处理，则actionscript将不会把一般的错误信息显示给用户。
语法结构：try{可能发生的错误语句;}catch(变量参数){处理确实发生错误的语句;}
范例：try{chkPasWord();}catch(showError){alter("发生错误"+showError);}

第一 function ioerrorhandler() 里面不要写参数么。。
第二 try catch 和 捕获 错误是两个东西。。
如果你选择了捕获 ioerror 则 不会 被 catch到
