jQuery组合框/自动完成但可编辑
我正在使用jQuery，但我需要它是可编辑的。我的意思是，如果一个值不在列表中，我需要捕获他们输入的值。使用上面链接中的示例，用户可能看不到他们的选择，例如C#，并且会键入他们的语言。我在默认行为中发现，如果在列表中找不到该值，它将清除用户响应 我添加了以下代码：jQuery组合框/自动完成但可编辑,jquery,combobox,Jquery,Combobox,我正在使用jQuery，但我需要它是可编辑的。我的意思是，如果一个值不在列表中，我需要捕获他们输入的值。使用上面链接中的示例，用户可能看不到他们的选择，例如C#，并且会键入他们的语言。我在默认行为中发现，如果在列表中找不到该值，它将清除用户响应 我添加了以下代码： options: { allowUserDefined: false }, 及 及 以防止清除响应。这几项改变确实奏效。但是由于在列表中找不到C#，因此没有选择返回选项 如何让代码返回输入字段中输入的内容？调试代码时，特别是在c

使用jQuery UI autocomplete combobox时，我自己要做的是声明combobox小部件，如下所示：
(function( $ ) {
$.widget( "ui.combobox", {
// default options
options: {
strict: false
},
_create: function() {
var self = this,
select = this.element.hide(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "",
strict = this.options.strict;
var input = this.input = $( "<input>" )
.insertAfter( select )
.val( value )
.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
});
},
autocomplete : function(value) {
this.element.val(value);
this.input.val(value);
},
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.value.match( matcher ) ) {
this.selected = valid = true;
return false;
}
});
if ( !valid ) {
// if strict is true, then unmatched values are not allowed
if ( strict ) {
// remove invalid value, as it didn't match anything
$( this ).val( "" );
select.val( "" );
}
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 );

input.autocomplete( "close" );

}
// pass empty string as value to search for, displaying all results

input.focus();

}
});
})( jQuery );

您可以使用darkajax的cleaner解决方案和以下代码行访问
请求。termvar valu = $("#combobox").parent().children()[1].value;
我能够得到组合框的值 我不知道这是否对任何人都有帮助，但通过给输入一个名称，值被提交了。。。。（当然，我删除了删除无效条目的代码）
