关于参数传递的问题

Question

function CheckSuccess(success,I){
   var comma=0
   for (i=0;i<success.value.length;i++){
   var x="A"+I
   var y="B"+I
   var z="C"+I   
  var ch = success.value.charAt(i);
if ((ch<"0" || ch>"9") && (ch!=".")) {
alert("此处只能输入数值");
success.value="";
success.focus();
              }
   }   z.innerText=Success_tj.x.value*1+Success_tj.y.value*1 }

Answer 1

Success_tj(z).innerText=Success_tj(x).value*1+Success_tj(y).value*1

Answer 2

或
eval("Success_tj."+z+".innerText=Success_tj."+x+".value*1+Success_tj."+y+".value*1")

Answer 3

这条可以：eval("Success_tj."+z+".innerText=Success_tj."+x+".value*1+Success_tj."+y+".value*1")
谢谢各位
