我的数据行名为模块,优先级,请求日期等,这些行是在我的网站上动态获取的。当从我的下拉列表中选择计算机请求的值时,有没有办法在名为“cost center”的模块下添加一行? 这是下拉列表的代码。
<span id="dg_form_ctl02_lbl_show_tag" style="display:inline-block;background- color:Transparent;border-color:Navy;border-width:3px;border-style:Double;font- family:Arial;font-size:12px;width:130px;">Module*</span>
</td><td>
<select name="dg_form$ctl02$DropDownList1" onchange="javascript:setTimeout('__doPostBack(\'dg_form$ctl02$DropDownList1\',\'\')', 0)" id="dg_form_ctl02_DropDownList1">
<option value="">--select one--</option>
<option value="Cellular Phone">Cellular Phone Request</option>
<option selected="selected" value="Computer">Computer Request (Up to VP Approval)</option>
<option value="Account Creation">Create Network/SAP Account</option>
<option value="Account Delete">Delete Network/SAP Account</option>
<option value="FIS">FIS</option>
<option value="FP">FP</option>
<option value="General">General Support</option>
<option value="Report">Reports</option>
<option value="SAP">SAP</option>
<option value="Web Application">Web Application</option>
</select>
</td>
</tr><tr style="background-color:White;">
<td valign="top">
这是我目前为警报所用的代码
function alertMe() {
var n = document.getElementById("dg_form_ctl02_DropDownList1").value;
if (n == "Computer") {
alert ('Changed');
答案 0 :(得分:0)
我认为这会有用
selectObject.add(option,before)
function GetSelectedValue(selectItem)
{
var index = document.getElementById(selectItem).selectedIndex;
alert("value =" + document.getElementById(selectItem).value);
alert("text =" + document.getElementById(selectItem).options[index].text);
}
<select id="mySelect">
<option>Apple</option>
<option>Pear</option>
<option>Banana</option>
<option>Orange</option>
