私はこれを行おうとしていますhttp://jqueryui.com/autocomplete/#combobox 問題は、オプションの上にマウスを置くと、オプションが消えて、「xが一致しなかった」というアドバイスが表示されることです。ここで、xはコンボボックスに書き込んだ文字です。今、私はサイトにあるスクリプトを投稿します：
(function( $ ) {
$.widget( "ui.combobox", {
_create: function() {
var input,
that = this,
wasOpen = false,
select = this.element.hide(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "",
wrapper = this.wrapper = $( "<span>" )
.addClass( "ui-combobox" )
.insertAfter( select );
function removeIfInvalid( element ) {
var value = $( element ).val(),
matcher = new RegExp( "^" + $.ui.autocomplete.escapeRegex( value ) + "$", "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
$( element )
.val( "" )
.attr( "title", value + " didn't match any item" )
.tooltip( "open" );
select.val( "" );
setTimeout(function() {
input.tooltip( "close" ).attr( "title", "" );
}, 2500 );
input.data( "ui-autocomplete" ).term = "";
}
}
input = $( "<input>" )
.appendTo( wrapper )
.val( value )
.attr( "title", "" )
.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;
that._trigger( "selected", event, {
item: ui.item.option
});
},
change: function( event, ui ) {
if ( !ui.item ) {
removeIfInvalid( this );
}
}
})
.addClass( "ui-widget ui-widget-content ui-corner-left" );
input.data( "ui-autocomplete" )._renderItem = function( ul, item ) {
return $( "<li>" )
.append( "<a>" + item.label + "</a>" )
.appendTo( ul );
};
$( "<a>" )
.attr( "tabIndex", -1 )
.attr( "title", "Show All Items" )
.tooltip()
.appendTo( wrapper )
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass( "ui-corner-all" )
.addClass( "ui-corner-right ui-combobox-toggle" )
.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", "" );
});
input.tooltip({
tooltipClass: "ui-state-highlight"
});
},
_destroy: function() {
this.wrapper.remove();
this.element.show();
}
});
})( jQuery );
$(function() {
$( "#combobox" ).combobox();
});
およびcss：
.ui-combobox {
position: relative;
display: inline-block;
}
.ui-combobox-toggle {
position: absolute;
top: 0;
bottom: 0;
margin-left: -1px;
padding: 0;
/* support: IE7 */
*height: 1.7em;
*top: 0.1em;
}
.ui-combobox-input {
margin: 0;
padding: 0.3em;
}
と私の選択（JSPで構築）
<select id="combobox"><option value="">Select one...</option>
<%for(int i=0;i<ut.size();i++){
out.print("<option value=\""+ut.get(i).getIdUtente()+
"\">"+ut.get(i).getNome()+" "+ut.get(i).getCognome()+" ("+ut.get(i).getIdUtente()+")"+"</option>");
}
%>
</select>
さて、私の問題はどこにありますか？前もって感謝します！
