求大神解决js脚本语句执行顺序问题

Question

  document.getElementById("comCountry").value = ConfigSettigs.Value1;
  document.getElementById("comCountry").fireEvent('onchange');两句 总是先执行下面的那句
而先执行下面的 那个Onchange函数调用事件就出问题了

Answer 1

意思就是说有时候呢没执行上面的语句就执行下面的去触发'onchange'事件了

Answer 2

不知道你要实现什么呢，document.getElementById("comCountry").fireEvent('onchange')
这个是直接触发，不管内容有没有改变都强制执行document.getElementById("comCountry").value = ConfigSettigs.Value1;
这个是自然触发，当内容改变后才去执行这两个不是一个概念

Answer 3

document.getElementById("comCountry").value = ConfigSettigs.Value1;
可是这个根本没有触发 onchange事件啊

Answer 4

因为这个我是写在OnLoad 事件里面的
而OnLoad的时候下拉框里面还没有值，直接加载的就是这个值，所以不会触发

Answer 5

事实上就是document.getElementById("comCountry").value = ConfigSettigs.Value1;触发了OnChange事件，跟你下面的document.getElementById("comCountry").fireEvent('onchange');没关系

Answer 6

可是我不加document.getElementById("comCountry").fireEvent('onchange');根本就没调用
Onchange函数啊
