javascript - jQuery UI AutoComplete Combobox Options require double click on iPhone -

-

i have created app cordova contains jquery custom autocomplete comboboxes. works on browser on physical android device. put app on iphone encounter small bug annoying end users.

the bug: once options displayed combobox user, must click once, hi-lights choice, , second click make selection. intended use on android devices click once on option make selection.

before clicks http://i.stack.imgur.com/cekbt.png

first click http://i.stack.imgur.com/jeafo.png

the first click should making selection instead hi-lights option , waits user click on highlighted option once again. same issue happens on iphone simulator on physical device, don't believe device specific.

here html

<div class="ui-widget"><select id="testcombo"></select></div>

js turn combobox

$("#testcombo").combobox()

and here custom widget being used combo box

(function( $ ) { $.widget( "custom.combobox", {     options: {         'userchanged': function() {     //@overridden if needed         } },  _create: function() {     this.wrapper = $( "<span>" )     .addclass( "custom-combobox" )     .insertafter( this.element );          this.element.hide();         this._createautocomplete();         this._createshowallbutton(); },  _createautocomplete: function() {         var selected = this.element.children( ":selected" ),     value = selected.val() ? selected.text() : "";          this.input = $( "<input>" )     .appendto( this.wrapper )     .val( value )     .attr( "title", "" )     .addclass( "custom-combobox-input ui-widget ui-widget-content ui-state-default ui-corner-left" )     .autocomplete({         delay: 0,         minlength: 0,         source: $.proxy( this, "_source" )     })     .tooltip({         tooltipclass: "ui-state-highlight"     });          this._on( this.input, {     autocompleteselect: function( event, ui ) {         ui.item.option.selected = true;         this._trigger( "select", event, {         item: ui.item.option         });     },      //* remove commented code below if user types     //a value not in options, gets removed      //autocompletechange: "_removeifinvalid"     autocompletechange: "userchanged"         }); },  _createshowallbutton: function() {         var input = this.input,     wasopen = false;          $( "<a>" )     .attr( "tabindex", -1 )     //      .attr( "title", "show items" )     .tooltip()     .appendto( this.wrapper )     .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() {         input.focus();          // close if visible         if ( wasopen ) {         return;         }          // pass empty string value search for, displaying results         input.autocomplete( "search", "" );     }); },  _source: function( request, response ) {         var matcher = new regexp( $.ui.autocomplete.escaperegex(request.term), "i" );         response( this.element.children( "option" ).map(function() {     var text = $( ).text();     if ( this.value && ( !request.term || matcher.test(text) ) )         return {         label: text,         value: text,         option:         };         }) ); },  _removeifinvalid: function( event, ui ) {          // selected item, nothing         if ( ui.item ) {     return;         }          // search match (case-insensitive)         var value = this.input.val(),     valuelowercase = value.tolowercase(),     valid = false;         this.element.children( "option" ).each(function() {     if ( $( ).text().tolowercase() === valuelowercase ) {         this.selected = valid = true;         return false;     }         });          // found match, nothing         if ( valid ) {     return;         }          // remove invalid value         this.input     .val( "" )     .attr( "title", value + " didn't match item" )     .tooltip( "open" );         this.element.val( "" );         this._delay(function() {     this.input.tooltip( "close" ).attr( "title", "" );         }, 2500 );         this.input.autocomplete( "instance" ).term = ""; },  _destroy: function() {         this.wrapper.remove();         this.element.show(); },  //set value combobox autocomplete : function(value) {     this.element.val(value);     this.input.val(value);       },  //set placeholder of combobox placeholder : function(value) {     this.element.attr("placeholder",value);     this.input.attr("placeholder",value); },  //used custom typed text autocombo getval: function(){     var value = this.input.val();     if (value === ""){     return null;     }else{     return value;     } },  userchanged: function() {     if($.isfunction(this.options.userchanged))             this.options.userchanged();     }  }); })( jquery );

the reason related tooltip. iphone firstly executing hover events next click real click event. had same problem , removed "hover" items solved problem.
