我在UserControll中使用RadComboBox我希望在RadComboBox中使用CheckBoxes绑定所有城市。因为我已编写代码如下:
FOR ASPX: -
<script type="text/javascript">
function getItemCheckBox(item) {
debugger;
//Get the 'div' representing the current RadComboBox Item.
var itemDiv = item.get_element();
//Get the collection of all 'input' elements in the 'div' (which are contained in the Item).
var inputs = itemDiv.getElementsByTagName("input");
for (var inputIndex = 0; inputIndex < inputs.length; inputIndex++) {
var input = inputs[inputIndex];
//Check the type of the current 'input' element.
if (input.type == "checkbox") {
return input;
}
}
return null;
}
function check() {
debugger;
alert("hello");
}
function getCities() {
var combo = $find("<%= cmbCity.ClientID %>");
var hdnAddressType = document.getElementById("<%= hfGeoLocation.ClientID %>");
var items = combo.get_items();
var selectedItemsTexts = "";
var selectedItemsValues = "";
var itemsCount = items.get_count();
for (var itemIndex = 0; itemIndex < itemsCount; itemIndex++) {
var item = items.getItem(itemIndex);
var checkbox = getItemCheckBox(item);
//Check whether the Item's CheckBox) is checked.
if (checkbox.checked) {
selectedItemsTexts += item.get_text() + ", ";
selectedItemsValues += item.get_value() + ",";
}
}
hdnAddressType.value = selectedItemsValues;
selectedItemsTexts = selectedItemsTexts.substring(0, selectedItemsTexts.length - 2);
selectedItemsValues = selectedItemsValues.substring(0, selectedItemsValues.length - 2);
//Set the text of the RadComboBox with the texts of the selected Items, separated by ','.
combo.set_text(selectedItemsTexts);
//Set the comboValue hidden field value with values of the selected Items, separated by ','.
combo.set_value(selectedItemsValues);
//Clear the selection that RadComboBox has made internally.
if (selectedItemsValues == "") {
combo.clearSelection();
}
}
</script>
<div>
<telerik:RadComboBox ID="cmbCity" runat="server" Height="200px" ExpandDirection="Up"
Width="130px">
<ItemTemplate>
<div id="chk">
<asp:CheckBox ID="chkCity" runat="server" onclick="getCities();" Text='<%#Eval("CityName")%>' />
</div>
</ItemTemplate>
</telerik:RadComboBox>
<asp:HiddenField ID="hfGeoLocation" runat="server" />
</div>
在代码背后。以下代码: -
protected void Page_Load(object sender, EventArgs e)
{
List<usp_SelectCmbCityResult> lstCity = null;
if (!Page.IsPostBack)
{
lstCity = new CityDomain().SelectCmbCity();
cmbCity.DataSource = lstCity;
cmbCity.DataValueField = "CityName";
cmbCity.DataTextField = "CityName";
cmbCity.DataBind();
MenUs.Common.Common.BindRadioButtonList(ref rbtnOrientation, typeof(MenUs.Common.Enums.Orientation));
MenUs.Common.Common.BindRadioButtonList(ref rbtnTargetGender, typeof(MenUs.Common.Enums.TargetGender));
MenUs.Common.Common.BindRadioButtonList(ref rbtnTargetMarital, typeof(MenUs.Common.Enums.TargetMaritalStatus));
}
}
当我点击/ CheckBox时,我是Gettig错误
Microsoft JScript运行时错误:'getCities'未定义
请告诉我什么是错的? 在此先感谢.....
解决了问题。实际上MasterPage中存在问题,这就是产生此错误的原因。 谢谢大家的支持......
答案 0 :(得分:0)
最好在浏览器看到它时看到Javascript代码,而不是使用嵌入式ASP标记。
这些ASP标签应该转换成字符串;我怀疑问题可能是这些字符串中的一个。我不知道cmbCity.ClientID
或hfGeoLocation.ClientID
的值是什么,但它们可能导致代码中断。如果它们包含引号或换行符,那么您的Javascript代码将无效。
您应该使用浏览器的“查看源”功能来查看代码在浏览器中的显示方式。这很可能会告诉你问题所在。
