我想使用
jquery禁用下拉列表项.
索引值为-1,值为——-内部——-.我一个接一个地尝试了以下语法(解决方案是类似问题的答案).他们都没有工作.我使用的是IE8.

var value="------- Internal -------";
$("[id*='ChildOrganizationDropDownList'] option[value=" + value + "]").prop('disabled','disabled');
$("#ChildOrganizationDropDownList option[value=" + value + "]").prop('disabled','disabled');
$("[id*='ChildOrganizationDropDownList']").option('------- Internal -------').prop('disabled',true);
$("id*='ChildOrganizationDropDownList' option[value='------- Internal -------']").prop('disabled','disabled');
$("[id*='ChildOrganizationDropDownList']").option("[value*='------- Internal -------']").prop('disabled',true);
$("[id*='ChildOrganizationDropDownList']").attr("disabled",$(_this.CustomerNameDropDownList).find("option[value='------- Internal -------']"));
设计师：Aspx
<div class="selectionControls">
<asp:CheckBox ID="chkSubcontracting" runat="server" Text="Subcontracting" Enabled="true" />
<asp:HiddenField ID="SubcontractingHiddenField" runat="server" />
<div class="subSelectionControl" id="AllowSubcotractingSelection" style="display: none;">
<div class="subContractingControls">
Parent BU:
<span>
<div class="subContractingControls">
supplier <em class="mandatoryIndicator">*</em>:
<span>
<asp:DropDownList ID="ChildOrganizationDropDownList" runat="server" Width="200px" />
<asp:HiddenField ID="IxChildOrganizationHiddenField" runat="server" />
</span>
</div>
</div>
</div>
Aspx.cs
public Dictionary<int,string> ChildOrganizations
{
set
{
var result = value;
result.Add(0,"Select supplier");
ChildOrganizationDropDownList.DataSource = result;
ChildOrganizationDropDownList.DataTextField = "value";
ChildOrganizationDropDownList.DataValueField = "key";
ChildOrganizationDropDownList.DataBind();
ChildOrganizationDropDownList.SelectedValue = "0";
}
}
解决方法
我用过它们,它对我有用：
https://jsfiddle.net/pz9curkb/1/
<select id="ChildOrganizationDropDownList">
<option value="Default">Default</option>
<option value="A">A</option>
<option value="B">------- Internal -------</option>
<option value="E">E</option>
</select>
$("#ChildOrganizationDropDownList option").each(function(){
if($(this).text() === "------- Internal -------"){
this.disabled = true;
}
});
请注意在此解决方案中我使用此而不是$(this),这意味着我使用了javascript提供的禁用选项
