Jquery uicombobox（自动完成）消失

我正在尝试这样做http://jqueryui.com/autocomplete/#combobox问题是，当我用鼠标选择一个选项时，选项将消失并且它出现了建议：“x不符合任何item“其中x是我在combobox中写的字母。 现在我发布网站上的脚本：

(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 = $( "" ) .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 = $( "" ) .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" ), "$1" ), 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 $( "
" ) .append( "" + item.label + "" ) .appendTo( ul ); }; $( "" ) .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(); }); 

和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; } 

和我的选择（用JSP构建）

  Select one... <%for(int i=0;i<ut.size();i++){ out.print(""+ut.get(i).getNome()+" "+ut.get(i).getCognome()+" ("+ut.get(i).getIdUtente()+")"+""); } %>  

现在，我的问题在哪里？ 提前致谢！

Answer 1

它也发生在我身上。 似乎是jQuery UI js文件被调用了两次。 删除一个，它会工作

Answer 2

这将在相关场景中发生，您可以同时引用主jQuery UI（jquery-ui.js）库和jquery ui自动完成的各个库。 jQuery-ui文件包含所有子节点，因此不需要同时引用它们。
