[問題] javascript 變數代入getElementById?
想請問一下為何第一種方式可行，第二種不可行呢?
第一種方式
var cells = lines[i].split(':');
var key = "layerAmount";
var el = document.getElementById(key);
el.value = cells[1];
第二種方式
var cells = lines[i].split(':');
var key = cells[0];
var el = document.getElementById(key);
el.value = cells[1];
cells[0] 是layerAmount 沒錯

改用jQuery 抓的到layerAmount 但塞不進去值 且下一個ID(gridRowCount)就又找不到了
