<strong><font face="宋体" size="3">第十四页：</font><font size="3">多于一个参数的函数</font></strong>
<p><font face="宋体" size="3">这是我定义的一个数组：</font>
<ul>
<pre><font face="宋体">
var monkeys = new Array("mattmarg","wendy",
"kristin","tim","aaron", "luke");
var kittyphile = new Array("wendy", "ruby",
"roscoe", "tim");
var discophile = new Array("mattmarg",
"john travolta", "wendy");
var happy = new Array("tim", "wendy",
"stimpy", "aaron");
var cranky = new Array("ren", "mattmarg","luke");
</font></pre>
</ul>
<p> </p>
<p><font face="宋体" size="3">随着这些数组的定义，arrayIntersect函数给出，我们可轻<br>
而易举的发现那些网猴酷爱迪斯科：爱跳舞的网猴</font></p>
<p> <font size="2"></font><font face="宋体" size="3">注意到尽管John Travolta喜爱迪斯科，但他不在monkeys请<br>
单中，则他就不是只爱跳舞的网猴为调用该函数值，可这么来：</font>
<ul>
<pre><font face="宋体">
<a href="#" onClick="arrayIntersect('dancing
monkeys',monkeys,discophile);">dancing monkeys</a>
</font></pre>
</ul>
<p> </p>
<p><font face="宋体" size="3">这是个具有3个参数的函数：一个代表交叉的姓名，第一个数组，<br>
及第二个数组。这也很容易发现爱猫的网猴名爱猫的网猴。</font></p>
<p> <font size="2"></font><font face="宋体" size="3">看一下源码：</font>
<ul>
<pre><font face="宋体">
<a href="#" onClick="arrayIntersect('monkeys who love
cats',monkeys,kittyphile);">cat-loving monkeys</a>
</font></pre>
</ul>
<p><font face="宋体" size="3">让我们看看arrayIntersect函数本身：</font>
<ul>
<pre><font face="宋体">
function arrayIntersect(intersect_name, array_1, array_2)
{
var the_list = "";
for (loop_1 = 0; loop_1 < array_1.length; loop_1++)
{
for (loop_2 = 0; loop_2 < array_2.length; loop_2++)
{
if (array_1[loop_1] == array_2[loop_2])
{
the_list = the_list + array_1[loop<br>_1] + " ";
}
}
}
alert("the " + intersect_name + " are: "+ the_list);
}
</font></pre>
</ul>
<p><font face="宋体" size="3">看看你是否已经弄懂本例中的循环。关键是函数第一行：</font>
<ul>
<pre><font face="宋体">
function arrayIntersect(intersect_name, array_1, array_2)
</font></pre>
</ul>
<p><font face="宋体" size="3">这里定义了一个叫arrayIntersect的函数，它有3个参数。就象上<br>
例，每个参数就象一个变量，当函数调用时赋值。因此，当函数被调<br>
用时：</font>
<ul>
<pre><font face="宋体">
arrayIntersect('dancing monkeys',monkeys,discophile);
</font></pre>
</ul>
<p> </p>
<p><font face="宋体" size="3">下列分配：</font>
<font size="2">
<ul>
<li><font face="宋体">intersect_name = 'dancing monkeys' </font></li>
<li><font face="宋体">array_1 = monkeys </font></li>
<li><font face="宋体">array_2 = discophile </font></li>
</ul>
</font>
<p><font size="2"></font><font face="宋体" size="3">唯一需注意的是，你必须以正确的参数数目来调用函数。如果你一旦<br>
象这样调用arrayIntersect：</font>
<ul>
<pre><font face="宋体">
arrayIntersect(monkeys,discophile);
</font></pre>
</ul>
<p> </p>
<font size="3">
<p align="JUSTIFY">将会出错。试一下看会发生什么错误。</p>
<p align="JUSTIFY">在任一标准的<font face="宋体">Javascript</font>程序中，函数都是基本的部件。因此理解其<br>
工作原理极其重要。这里是一个测试你对这项工作理解多少的练习。<br>
再综合地做一下本课中其它练习，再在你自己的浏览器中应用。</p>
