由於javascript函數無法按我想象的參數傳址,因此有時就會返回多個值.使用如下代碼:
參考:http://blog.csdn.net/leftfist/archive/2008/04/09/2269415.aspx
<html>
<body>
<script>
function f(s1, man)
{
s1="byebye";
man=new Object();
man.name="YZX";
return [s1, man];
}
s1="hello";
man=new Object();
man.name="name";
man.age=30;
var ret=f(s1, man);
s1=ret[0];
man=ret[1];
alert ("s1=" + s1);
alert ("man.name=" + man.name);
alert ("man.age=" + man.age);
</script>
</body>
</html>
有時傳回值中只要用第1個,則可以寫成:
s1=f(s1, man)[0];
另外傳回值還可以使用具名引數的形式:
return {_s1:s1, _man:man};
這樣傳回值使用時:
var ret=f(s1, man);
s1=ret._s1;
前面一種是以數組的形式返回結果(ret有length屬性),後面一種是以對象的形式返回結果.
