我无法找到解决问题的方法。我有 JqueryUI 给出的组合框示例。
我的来源是 Json Ajax,所有这些都运行良好。但我想手动将一个项目添加到我的组合框(我想将其附加到 Ajax 项目),上面写着“添加一个新项目”,当我点击它时,我的模态表单变得可见。
我在我的代码中添加了一些注释,我需要帮助来更多地解释我的问题。
$('#combobox_scenario').combobox({
source: function( request, response ) {
$.ajax({
url: "?module=gestionApplication&action=getListeScenarios&option="+encodeURI($(".ui-combobox:first input").val()),
dataType: "json",
success: function( data ) {
response( $.map( data, function( item ) {
return {
label: item.test,
value: item.test,
option: this
}
}));
//I want to add an item Here !
//response.add({label: 'Ajouter un Scénario',value: 'Ajouter un Scénario',option : this});
console.log(response);
}
});
},
selected: function(event, ui) {
var scenario = ui.item2;
//if (scenario = "This Item added manually")
//MyForm.show()
//else
$.ajax({
url: "?module=gestionApplication&action=getScenario&option="+encodeURI(scenario),
dataType: "json",
success: function( data ) {
data = data[0];
$("#scenario").show();
$("#scenario").html('<hr><h2>Informations sur le scénario '+data.TEST+'</h2><p>Description : '+data.DESCRIPTION+'</p>'+'<p>Application : '+data.APPLICATION+'</p>');
}
});
//EndIf
}
});

这是我的自动完成组合框代码:
(function( $ ) {
$.widget( "ui.combobox", {
_create: function() {
var input,
self = this,
source = this.options,
select = this.element.hide(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "",
wrapper = this.wrapper = $( "<span>" )
.addClass( "ui-combobox" )
.insertAfter( select );
input = $( "<input>" )
.appendTo( wrapper )
.val( value )
.addClass( "ui-state-default ui-combobox-input" )
.autocomplete({
delay: 0,
minLength: 0,
// Need define source in my main js
source: this.options.source,
select: function( event, ui ) {
ui.item.option.selected = true;
self._trigger( "selected", event, {
item: ui.item.option,
item2 : ui.item.label
});
},
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 ).text().match( matcher ) ) {
this.selected = valid = true;
return false;
}
});
if ( !valid ) {
// remove invalid value, as it didn't match anything
$( this ).val( "" );
select.val( "" );
input.data( "autocomplete" ).term = "";
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 );
};
$( "<a>" )
.attr( "tabIndex", -1 )
.attr( "title", "Show All Items" )
.appendTo( wrapper )
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass( "ui-corner-all" )
.addClass( "ui-corner-right ui-combobox-toggle" )
.click(function() {
// close if already visible
if ( input.autocomplete( "widget" ).is( ":visible" ) ) {
input.autocomplete( "close" );
return;
}
// work around a bug (likely same cause as #5265)
$( this ).blur();
// pass empty string as value to search for, displaying all results
input.autocomplete( "search", "" );
input.focus();
});
},
destroy: function() {
this.wrapper.remove();
this.element.show();
$.Widget.prototype.destroy.call( this );
}
});
})( jQuery );
