我想實現一個使用jquery ui插件的自動完成組合框。jquery自動完成組合框錯誤:未捕獲TypeError:對象[對象對象]沒有方法'按鈕'
與下文提到的代碼我是能夠實現自動填充的一部分,但不是下拉部分(由於未捕獲的類型錯誤的下拉箭頭是不可見)
$.widget("ui.combobox", {
_create: function() {
var input,
self = this,
select = this.element.hide(),
selected = select.children(":selected"),
value = selected.val() ? selected.text() : "",
wrapper = this.wrapper = $("<span>")
.addClass("ui-combobox")
.insertAfter(select);
input = $("<input>")
.appendTo(wrapper)
.val(value)
.addClass("ui-state-default ui-combobox-input")
.autocomplete({
delay: 0,
minLength: 0,
source: function(request, response) {
var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");
response(select.children("option").map(function() {
var text = $(this).text();
if (this.value && (!request.term || matcher.test(text)))
return {
label: text.replace(
new RegExp(
"(?![^&;]+;)(?!<[^<>]*)(" +
$.ui.autocomplete.escapeRegex(request.term) +
")(?![^<>]*>)(?![^&;]+;)", "gi"
), "<strong>$1</strong>"),
value: text,
option: this
};
}));
},
select: function(event, ui) {
ui.item.option.selected = true;
self._trigger("selected", event, {
item: ui.item.option
});
},
change: function(event, ui) {
if (!ui.item) {
var matcher = new RegExp("^" + $.ui.autocomplete.escapeRegex($(this).val()) + "$", "i"),
valid = false;
select.children("option").each(function() {
if ($(this).text().match(matcher)) {
this.selected = valid = true;
return false;
}
});
if (!valid) {
// remove invalid value, as it didn't match anything
$(this).val("");
select.val("");
input.data("autocomplete").term = "";
return false;
}
}
}
})
.addClass("ui-widget ui-widget-content ui-corner-left");
input.data("autocomplete")._renderItem = function(ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.append("<a>" + item.label + "</a>")
.appendTo(ul);
};
$("<a>")
.attr("tabIndex", -1)
.attr("title", "Show All Items")
.appendTo(wrapper)
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass("ui-corner-all")
.addClass("ui-corner-right ui-combobox-toggle")
.click(function() {
// close if already visible
if (input.autocomplete("widget").is(":visible")) {
input.autocomplete("close");
return;
}
// work around a bug (likely same cause as #5265)
$(this).blur();
// pass empty string as value to search for, displaying all results
input.autocomplete("search", "");
input.focus();
});
},
destroy: function() {
this.wrapper.remove();
this.element.show();
$.Widget.prototype.destroy.call(this);
}
});
$("#combobox").combobox();
上面的代碼是在document.ready下。 由於'.button'方法引發錯誤。
的HTML:
<tr>
<td><label>Country:</label></td>
<td>
<div class="ui-widget">
<select id="combobox">
<option value="">Select one...</option>
<option value="ActionScript">ActionScript</option>
<option value="AppleScript">AppleScript</option>
<option value="Asp">Asp</option>
<option value="BASIC">BASIC</option>
<option value="C">C</option>
</select>
</div>
</td>
</tr>
組合框的CSS,
.ui-combobox {
position: relative;
display: inline-block;
}
.ui-combobox-toggle {
position: absolute;
top: 0;
bottom: 0;
margin-left: -1px;
padding: 0;
/* adjust styles for IE 6/7 */
*height: 1.7em;
*top: 0.1em;
}
.ui-combobox-input {
margin: 0;
padding: 0.3em;
}
腳本序列,
<script type="text/javascript" src="<?php echo base_url('/assets/js/jquery.js'); ?>"></script>
<script type="text/javascript" src="<?php echo base_url('/assets/js/validation.js'); ?>"></script>
<script type="text/javascript" src="<?php echo base_url('/assets/autocomplete/js/jquery-ui-1.8.21.custom.min.js'); ?>"></script>
<?= $_scripts ?>
- 的jQuery 1.7.2版本,jQuery UI的版本21年1月8日
- 我試圖重新安排腳本
- 有不同的jQuery版本沒有多個實例的序列。
任何幫助,將不勝感激。謝謝!
我遇到了同樣的問題,但我相信我的問題只包括'jquery-1.7.2.min.js',並忘記'jquery-ui-1.8.21.custom.min' – 2012-07-10 01:40:51
