需要一些帮助。
我可以将自定义值设置为组合框,即列表中不存在的值。
这意味着我自己的值未在列表中列出
这是代码。
(function( $ ) {
$.widget( "ui.combobox", {
_create: function() {
this.wrapper = $( "<span>" )
.addClass( "custom-combobox" )
.insertAfter( this.element )
.attr('id', this.element[0].id+"_combobox");
this.element.hide();
this._createAutocomplete();
this._createShowAllButton();
},
_createAutocomplete: function() {
var selected = this.element.children(":selected");
this.input = $( "<input>" )
.appendTo( this.wrapper )
.attr( "title", '<fmt:message key="page.claim.personalclaimnotification.injury.select_info" />' )
.val(selected.text())
.css({
color: function( index, value ) {
if (this.value == '<fmt:message key="page.claim.search.object.name" />') {
return "#777";
}
},
fontStyle: function( index, value ) {
if (this.value == '<fmt:message key="page.claim.search.object.name" />') {
return "italic";
}
},
width: "286px"
})
.attr("maxlength", 256)
.addClass( "custom-combobox-input ui-widget ui-widget-content ui-state-default ui-corner-left" )
.autocomplete({
delay: 0,
minLength: 3,
source: $.proxy( this, "_source" )
})
// executes when user selects illness from list
this._on( this.input, {
autocompleteselect: function( event, ui ) {
ui.item.option.selected = true;
this._trigger( "select", event, {
item: ui.item.option
});
},
autocompletechange: "_addIfInvalid"
});
}, /* _createAutocomplete close */
_createShowAllButton: function() {
var input = this.input,
wasOpen = false;
$( "<a>" )
.attr( "tabIndex", -1 )
.appendTo( this.wrapper )
.attr( "title", '<fmt:message key="page.claim.personalclaimnotification.injury.select_info" />' )
.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() {
// Close if already visible
if ( wasOpen ) {
return;
}
// Pass triple spaces as value to search for, displaying all results (each has triple spaces at the end)
input.autocomplete( "search", " " );
});
}, /* _createShowAllButton close */
_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
};
}) );
},
_addIfInvalid: 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;
}
alert("value "+ value +" this.element "+ this.element[0].id );
// Remove invalid value
this.input
.val(value)
.attr( "title", value + " didn't match any item" )
.tooltip( "open" );
//this.element.val(value);
//this.input.val(value);
$('select').val(value);
this._delay(function() {
this.input.tooltip( "close" ).attr( "title", "" );
}, 2500 );
this.input.autocomplete( "instance" ).term = "";
},
_destroy: function() {
this.wrapper.remove();
this.element.show();
}
}); /* widget close */
})( jQuery ); /* function close */
$(function() {
$( ".objectComboBox" ).combobox();
});
如果下拉列表中未列出该元素,则应将该用户输入的元素作为值并保留在组合框字段中。
添加字段

我为你制作了一个剧本。可能会对你有用。
<select id="combobox" >
<option>abc</option>
<option>deg</option>
<option>gcc</option>
</select>
<input type="text" id="addfieldtoddl" /><input type="button" value="add" id="add" onclick="addfieldtoddl()" />
<script>
$(document).ready(function(){
$("#combobox").combobox();
});
function addfieldtoddl() {
var YourValue = $("#addfieldtoddl").val();
$('#combobox').append('<option val="'+ YourValue +'">'+ YourValue +'</option>');
$("#combobox").combobox();
}
</script>
