请高手进来帮我看下这段代码

Question

对, 程序属于“硬”编码，if (currentNum==0&&listLength!=1 ){ 
if (currentNum==1&&listLength!=2 ){ 
if (currentNum==2&&listLength!=3 ){ 
你可以照着往上加记住同时修改下面的部分
if (currentNum==3 ){ 
if (currentNum==1&&listLength==2 ){ 
if (currentNum==2&&listLength==3 ){ 

Answer 1

循环？
for(var i=0;i<6;i++){
if(currentNum==i&&listLength!=i+1){
moveElement('ifocus_piclist',0,-225*(i+1),5); 
classNormal('ifocus_btn','ifocus_tx'); 
classCurrent('ifocus_btn','ifocus_tx',i+1); 
}
if(currentNum==i&&listLength=i+1){
moveElement('ifocus_piclist',0,0,5); 
classNormal('ifocus_btn','ifocus_tx'); 
classCurrent('ifocus_btn','ifocus_tx',0);  }
}

Answer 2

这里还有一个当前图片移动位置的问题    moveElement('ifocus_piclist',0,-225*(i+1),5);
