【问题描述】：
我希望在用户选择用户 ID 之后发生这种情况，然后用户 ID 显示在第一个只读文本框中，然后 onChange 事件应该在它显示在第一个只读文本框上时触发，以便它可以将此用户 ID 复制到第二个文本框。但是它不起作用，它只起作用是用户ID显示在第一个文本框上，但 onChange 不会触发第二个文本框。
这里有一半的工作代码：
<tr>
<td align="right">
Secondary Owner
</td>
<td>
<input id="Hidden1" type="hidden" />
<asp:TextBox ID="tbAdd_Sowner" runat="server" Enabled="false"></asp:TextBox>
<input id="Hidden2" type="hidden" />
<input id="Hidden3" type="hidden" />
<a href="javascript:void(0)" onclick="GalModalTOCCDialog(Hidden1, tbAdd_Sowner, Hidden2,Hidden3)">
Get User ID</a>
<asp:RequiredFieldValidator ID="RequiredFieldValidator7" ValidationGroup="g1" runat="server" ErrorMessage="* Required" ControlToValidate="tbAdd_Sowner"> <b style="color:Red;"> * </b></asp:RequiredFieldValidator>
<asp:ValidatorCalloutExtender ID="ValidatorCalloutExtender8" runat="server" TargetControlID="RequiredFieldValidator7">
</asp:ValidatorCalloutExtender>
</td>
</tr>
<tr>
<td align="right">Secondary Owners</td>
<td>
<asp:TextBox ID="tbAdd_Sphone" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator13" ValidationGroup="g1" runat="server" ErrorMessage="* Required" ControlToValidate="tbAdd_Sphone"> <b style="color:Red;"> * </b></asp:RequiredFieldValidator>
<asp:ValidatorCalloutExtender ID="ValidatorCalloutExtender9" runat="server" TargetControlID="RequiredFieldValidator13">
</asp:ValidatorCalloutExtender>
</td>
</tr>
然后<head> 中的 javascript 代码复制第一个文本框值并放入第二个文本框：
<script>
function getUserID() {
document.getElementById('tbAdd_Sphone').value = document.getElementById('tbAdd_Sowner').value;
}
document.getElementById('tbAdd_Sowner').onchange = getUserID();
</script>
已编辑：我在这里添加了一个 GALModalDialog.js 代码，因为你们中的一些人想看看它喜欢什么。我还有列出要选择的用户 ID 的 GALToCCDialong.asp 和从 AD 获取用户 ID 的 XMLGALListbox.asp。
function PopulateListboxFromString(oListbox,vNames,vUserIDs){
var oArrayUserNames = vNames.value.split(';');
var oArrayUserIDs = vUserIDs.value.split(';');
for (var index=0;index < oArrayUserIDs.length;index++) {
if (oArrayUserNames[index] != ''){
var oOption = document.createElement("OPTION");
oListbox.options.add(oOption);
oOption.innerText = oArrayUserNames[index];
oOption.value = oArrayUserIDs[index];
}
}
};
function GalModalTOCCDialog(oTONames, oTOUserIDs,oCCNames, oCCUserIDs ) {
if (oCCNames != null){
var oInputArray = new Array(oTONames.value,oTOUserIDs.value,oCCNames.value,oCCUserIDs.value);
} else {
var oInputArray = new Array(oTONames.value,oTOUserIDs.value,'','');
}
var oOutputArray = window.showModalDialog('GalAccess/GALToCCDialog.asp', oInputArray, 'dialogWidth:510px;dialogHeight:400px;status:no;help:no;');
// Check if we get something back;
// User might have closed the window without using the buttons
if (oOutputArray != null){
//first element is true if user clicked OK

} else {
oTONames.value = oOutputArray[1];
oTOUserIDs.value = oOutputArray[2];
}
}
}
return false;
}
function GalModalDialog(oSelectObject, oUserID) {
if (oUserID == null){
// there is a select object to fill data from
// fill the input array
var oInputArray = new Array(new Array(oSelectObject.options.length),new Array(oSelectObject.options.length));
for (var index=0;index < oInputArray[0].length;index++) {
oInputArray[0][index] = oSelectObject.options[index].innerText;
oInputArray[1][index] = oSelectObject.options[index].value;
};
var oOutputArray = window.showModalDialog('../GALDialog/GALModalDialog.asp', oInputArray, 'dialogWidth:500px;dialogHeight:320px;status:no;help:no;');

// User might have closed the window without using the buttons
if (oOutputArray != null){
//first element is true if user clicked OK
if (oOutputArray[0]) {
//remove existing from end to beginning otherwise not all options are removed.
var length=oSelectObject.options.length;
for (var index=length-1;index >= 0;index--) {
oSelectObject.options[index] = null;
};
// copy the array
for (var index=0;index < oOutputArray[1].length;index++) {
var oOption = document.createElement("OPTION");
oSelectObject.options.add(oOption);
oOption.innerText = oOutputArray[1][index];
oOption.value = oOutputArray[2][index];
};
}
}
} else
{
// there are 2 text objects to fill data from; the first contains the name, the secound the userid.
//if (oSelectObject.value != '' ) {
// var oInputArray = new Array(new Array(1),new Array(1));
//
// oInputArray[0][0] = oSelectObject.value;
// oInputArray[1][0] = oUserID.value;
//} else {
var oInputArray = new Array(new Array(0),new Array(0));
//}
var oOutputArray = window.showModalDialog('../GALDialog/GALModalDialog.asp', oInputArray, 'dialogWidth:500px;dialogHeight:320px;status:no;help:no;');
if (oOutputArray != null){
//first element is true if user clicked OK
if (oOutputArray[0]) {
// copy the data
oSelectObject.value = oOutputArray[1][0];
oUserID.value = oOutputArray[2][0];
}
}
}
return false;
}
已编辑： 这里是 GALToCCDialog.asp 的代码。在SubmitOnclick 函数和else if(vAction == 'OK') 中，我从选定的用户ID 中单击“确定”按钮以提交到文本框。

【问题讨论】：
-
您需要使用我认为的服务器控件的 ClientID。并且您正在尝试在函数之外添加EventListener。
-
用户ID在选择后已经插入到tbAdd_Sowner。 onChange 应该在插入时触发。
-
你试图在函数外添加EventListener ..这不是问题吗？
