Question

我在表格上减少了5个,根据表格,我有需要用户投入的DIV要素。我在第一个下级名单上显示第一个数字四级,并用风格=“显示:无”;

我正在寻找一份 Java稿,在我从第2次下班名单上选择任何选择时,将显示第二个DIV。

欢迎任何援助。

Thanks in advance, Ryan Smith

Answer 1

这里的一个例子是,我增加了与选定名字相同的识别资料。

http://jsfiddle.net/mplungjan/32Ukf/

Plain JS

var sels = {drop2:"legb1",drop3:"legc1",drop4:"legd1",drop5:"lege1"};  
window.onload=function() {
  for (var sel in sels) {
      document.getElementById(sels[sel]).style.display = document.getElementById(sel).selectedIndex>0?"block":"none";
      document.getElementById(sel).onchange=function() {
        document.getElementById(sels[this.id]).style.display = this.selectedIndex>0?"block":"none";
      }
    }
}

Answer 2

我将改写一个比值,将选择的<条码><> > 值/代码>改为<条码>。下面的法典应该使你朝着正确的方向迈进。

<select name= drop1  style="width:150px;" onchange="ToggleDiv(this.value)"> 
    <option value="lege1">Show lege1</option>
</select>

然后采用这种方法:

function ToggleDiv(id)
{
    document.getElementById(id).style.display = "block";
}
