javascript - 减少重复函数的 JavaScript 权重

Question

我不完全是 JS 专业人士，虽然不漂亮或高效，但这是有效的。

实际上，我在表单中有重复的字段组，并允许用户根据需要将数据从第一个字段复制到所有 5 个字段。

如何使这段代码更高效？

function data_copy() {
if(document.pixelform.copy[0].checked){

document.pixelform.pixelpostclickinterval2.value=document.pixelform.pixelpostclickinterval1.value;
document.pixelform.pixelpostviewinterval2.value=document.pixelform.pixelpostviewinterval1.value;
document.pixelform.pixelsegmentinterval2.value=document.pixelform.pixelsegmentinterval1.value;

document.pixelform.pixelpostclickinterval3.value=document.pixelform.pixelpostclickinterval1.value;
document.pixelform.pixelpostviewinterval3.value=document.pixelform.pixelpostviewinterval1.value;
document.pixelform.pixelsegmentinterval3.value=document.pixelform.pixelsegmentinterval1.value;

document.pixelform.pixelpostclickinterval4.value=document.pixelform.pixelpostclickinterval1.value;
document.pixelform.pixelpostviewinterval4.value=document.pixelform.pixelpostviewinterval1.value;
document.pixelform.pixelsegmentinterval4.value=document.pixelform.pixelsegmentinterval1.value;

document.pixelform.pixelpostclickinterval5.value=document.pixelform.pixelpostclickinterval1.value;
document.pixelform.pixelpostviewinterval5.value=document.pixelform.pixelpostviewinterval1.value;
document.pixelform.pixelsegmentinterval5.value=document.pixelform.pixelsegmentinterval1.value;

} else {

document.pixelform.pixelpostclickinterval2.value="";
document.pixelform.pixelpostviewinterval2.value="";
document.pixelform.pixelsegmentinterval2.value="";

document.pixelform.pixelpostclickinterval3.value="";
document.pixelform.pixelpostviewinterval3.value="";
document.pixelform.pixelsegmentinterval3.value="";

document.pixelform.pixelpostclickinterval4.value="";
document.pixelform.pixelpostviewinterval4.value="";
document.pixelform.pixelsegmentinterval4.value="";

document.pixelform.pixelpostclickinterval5.value="";
document.pixelform.pixelpostviewinterval5.value="";
document.pixelform.pixelsegmentinterval5.value="";

}
}

使用循环:

for (var i = 2; i <= 5; i++)
{
  document.pixelform["pixelpostclickinterval" + i].value=document.pixelform.pixelpostclickinterval1.value;
  document.pixelform["pixelpostviewinterval" + i].value=document.pixelform.pixelpostviewinterval1.value;
  document.pixelform["pixelsegmentinterval" + i].value=document.pixelform.pixelsegmentinterval1.value;
}
