出于某种原因，组合框按钮不会在 IE 或 Chrome 上显示，所以我最终只有一个文本框。有人知道如何解决吗？
使用最新的 jquery/jqueryui/combobox 版本。
这是我编辑的 ui.combobox 版本(特别是因为原始版本没有为新元素提供 ID)，还有组合框大小的修复:
(function( $ ) {
$.widget( "ui.combobox", {
_create: function() {
var self = this,
id = this.element.attr("id"),
select = this.element,
theWidth = select.width(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "";
select.hide();
//fix, doesnt let the element beign too short.
if(theWidth < 110) {
theWidth = 110;
}
var input = $('<input id="' + id + '-combo" style="width: ' + theWidth + 'px;">')
//.insertAfter( select )
.val( value )
.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 {
id: this.value,
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;
self._trigger( "selected", event, {
item: ui.item.option
});
},
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.value.match( matcher ) ) {
this.selected = valid = true;
return false;
}
});
if ( !valid ) {
// remove invalid value, as it didn't match anything
$( this ).val( "" );
select.val( "" );
return false;
}
}
}
})
.addClass( "ui-widget ui-widget-content ui-corner-left" );
var span = $('<span style="white-space: nowrap;"></span>')
.append(input).insertAfter( select );
input.data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append( "<a>" + item.label + "</a>" )
.appendTo( ul );
};
$("<button id='" + id + '-combo-button' + "> </button>")
.attr( "tabIndex", -1 )
.attr( "title", "Mostrar Todos os itens" )
.insertAfter( input )
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass( "ui-corner-all" )
.addClass( "ui-corner-right ui-button-icon" )
.click(function() {
// close if already visible
if ( input.autocomplete( "widget" ).is( ":visible" ) ) {
input.autocomplete( "close" );
return;
}
// pass empty string as value to search for, displaying all results
input.autocomplete( "search", "" );
input.focus();
});
}
});
})( jQuery );
最佳答案
这是我 friend 指出的修复方法。这个版本的 ui.combobox 具有自动宽度，并且我在网络上发现了一些修复。也适用于 ie。
(function( $ ) {
$.widget( "ui.combobox", {
_create: function() {
var self = this,
id = this.element.attr("id"),
select = this.element,
theWidth = select.width(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "";
select.hide();
//fix, doesnt let the element beign too short.
if(theWidth < 110) {
theWidth = 110;
}
var input = $('<input id="' + id + '-combo" style="width: ' + theWidth + 'px;">')
//.insertAfter( select )
.val( value )
.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 {
id: this.value,
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;
self._trigger( "selected", event, {
item: ui.item.option
});
},
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.value.match( matcher ) ) {
this.selected = valid = true;
return false;
}
});
if ( !valid ) {
// remove invalid value, as it didn't match anything
$( this ).val( "" );
select.val( "" );
return false;
}
}
}
})
.addClass( "ui-widget ui-widget-content ui-corner-left" );
var span = $('<span style="white-space: nowrap;"></span>')
.append(input).insertAfter( select );
input.data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append( "<a>" + item.label + "</a>" )
.appendTo( ul );
};
$("<button id='" + id + "-combo-button'> </button>")
.attr( "tabIndex", -1 )
.attr( "title", "Mostrar Todos os itens" )
.insertAfter(input)
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass( "ui-corner-all" )
.addClass( "ui-corner-right ui-button-icon" )
.click(function() {
// close if already visible
if ( input.autocomplete( "widget" ).is( ":visible" ) ) {
input.autocomplete( "close" );
return;
}
// pass empty string as value to search for, displaying all results
input.autocomplete( "search", "" );
input.focus();
});
}
});
})( jQuery );
