我在下拉列表中使用http://jqueryui.com/autocomplete/#combobox，效果很好。 我的问题是当我从后面的代码中禁用下拉列表时它不起作用。
我的代码在这里。
ASPX
<asp:DropDownList runat="server" CssClass="Dropdown" ID="ddlStatus"> </asp:DropDownList>
JS
function pageLoad() {
/******** Auto Complete *********************/
$(function () {
$("#<%= ddlStatus.ClientID %>").combobox();
});
(function ($) {
$.widget("custom.combobox", {
_create: function () {
this.wrapper = $("<span>")
.addClass("custom-combobox")
.insertAfter(this.element);
this.element.hide();
this._createAutocomplete();
this._createShowAllButton();
},
_createAutocomplete: function () {
var selected = this.element.children(":selected"),
value = selected.val() ? selected.text() : "";
this.input = $("<input>")
.appendTo(this.wrapper)
.val(value)
.attr("title", "")
.addClass("custom-combobox-input ui-widget ui-widget-content ui-state-default ui-corner-left")
.autocomplete({
delay: 0,
minLength: 0,
source: $.proxy(this, "_source")
})
.tooltip({
tooltipClass: "ui-state-highlight"
});
this._on(this.input, {
autocompleteselect: function (event, ui) {
ui.item.option.selected = true;
this._trigger("select", event, {
item: ui.item.option
});
__doPostBack('<%= upnlTab.ClientID %>', this.element.attr("id"));
},
autocompletechange: "_removeIfInvalid"
});
},
_createShowAllButton: function () {
var input = this.input,
wasOpen = false;
$("<a>")
.attr("tabIndex", -1)
//.attr("title", "Show All Items")
//.tooltip()
.appendTo(this.wrapper)
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass("ui-corner-all")
.addClass("custom-combobox-toggle ui-corner-right")
.mousedown(function () {
wasOpen = input.autocomplete("widget").is(":visible");
})
.click(function () {
input.focus();
// Close if already visible
if (wasOpen) {
return;
}
// Pass empty string as value to search for, displaying all results
input.autocomplete("search", "");
});
},
_source: function (request, response) {
var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");
response(this.element.children("option").map(function () {
var text = $(this).text();
if (this.value && (!request.term || matcher.test(text)))
return {
label: text,
value: text,
option: this
};
}));
},
_removeIfInvalid: function (event, ui) {
// Selected an item, nothing to do
if (ui.item) {
return;
}
// Search for a match (case-insensitive)
var value = this.input.val(),
valueLowerCase = value.toLowerCase(),
valid = false;
this.element.children("option").each(function () {
if ($(this).text().toLowerCase() === valueLowerCase) {
this.selected = valid = true;
return false;
}
});
// Found a match, nothing to do
if (valid) {
return;
}
// Remove invalid value
if (value != '') {
this.input
.val("")
.attr("title", value + " didn't match any item")
.tooltip("open");
this.element.val("");
this._delay(function () {
this.input.tooltip("close").attr("title", "");
}, 2500);
this.input.data("ui-autocomplete").term = "";
} else {
this.input.val("");
this.element.val("");
this.input.data("ui-autocomplete").term = "";
}
__doPostBack('<%= upnlTab.ClientID %>', this.element.attr("id"));
},
_destroy: function () {
this.wrapper.remove();
this.element.show();
}
});
})(jQuery);
}

基于一些验证我称之为
ddlStatus.Enabled = false;
这里有一个答案，我不是要让它与我的代码一起工作。 Disable jQuery ComboBox when underlying DropDownList is disabled
答案 0 :(得分：0)
我就是这样做的。请参阅* *。
