请教，javascript不会编了

下面函数的写法显然不好,我想改为后面的函数调用形式

function clk_content(no)
{
switch(no)

我想将case中相似的if语句改为函数调用形式，现在难点在几个变量名不同，虽然if..else结构一样并且变量个数也一样。
function clk_content(no)
{
switch(no)
{
case 1:
set_page(x,y);
calcu();
break;
case 2:
set_page(x,y);
calcu();
break;
case 3:
set_page(x,y);
calcu();
break;
case 4:
set_page(x,y);
calcu();
break;
case 5:
set_page(x,y);
calcu();
break;
case 6:
set_page(x,y);
calcu();
break;
case 7:
set_page(x,y);
calcu();
break;
case 8:
set_page(x,y);
calcu();
break;
case 9:
set_page(x,y);
calcu();
break;
case 10:
set_page(x,y);
calcu();
break;
}
}


function set_page(x,y)
{
if (page.slct_x_1.value == 0)
{
page.slct_x_2.disabled = true;
page.slct_x_2.value = 0;
page.y.disabled = true;
page.y.value = '';
}
else
{
page.slct_x_2.disabled = false;
page.y.disabled = false;
page.slct_x_3.disabled = true;
page.slct_x_3.value = 0;
}
if (page.slct_x_3.value != 0)
{
page.slct_x_1.disabled = true;
page.slct_x_1.value = 0;
page.slct_x_2.disabled = true;
page.slct_x_2.value = 0;
page.y.disabled = true;
page.y.value = '';
}
}

用eval

[vasualsam]

谢谢楼上的，调通了。
eval是javascript的内部函数吧，从哪里能查到它的用法。
见笑了。

[angelheavens]

我看比较有规律,为何不用循环呢!?

[vasualsam]

谢谢回复

其实几个case间的区别仅在于名字的不同，如用循环不知怎么写才能给其赋值，现在想不通怎么实现，根本问题是如何用不同的字符组装成不同的变量，还能给其赋值。

[angelheavens]

就用 js中的eval()呀,比如:
for(var i=0;i<str.length;i++){
eval('page.slct_x_'+i+'.disabled = true');
//...
}
//...
