我在用jQuery 自动完成它适用于现有元素，但不适用于动态添加的元素。
这是我的自动完成代码（我做了一些更改）
$(function() {
(function( $ ) {
$.widget( "ui.combobox", {
_create: function() {
var self = this,
select = this.element.hide(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "";
var input = this.input = $( ".editableCombobox" ) // your input box
//.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 {
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;
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 ( $( this ).text().match( matcher ) ) {
this.selected = valid = true;
return false;
}
});
//if ( !valid ) {
// remove invalid value, as it didn't match anything
//$( 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 );
};
this.button = $( "<button type='button'> </button>" )
.attr( "tabIndex", -1 )
.attr( "title", "Show All Items" )
.insertAfter( input )
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass( "ui-corner-all" )
//.addClass( "ui-corner-right ui-button-icon" )
.live('click',function() {
// close if already visible
if ( $(this).prev().autocomplete( "widget" ).is( ":visible" ) ) {
$(this).prev().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
$(this).prev().autocomplete( "search", "" );
$(this).prev().focus();
});
},
destroy: function() {
this.input.remove();
this.button.remove();
this.element.show();
$.Widget.prototype.destroy.call( this );
}
});
})( jQuery );
$( "#combobox" ).combobox();
$( "#toggle" ).live('click',function() {
$( "#combobox" ).toggle();
});
});
这是我添加新元素的代码
var selectedRow = $('#contactGroup'+rowId);
var clonedRow = selectedRow.clone();
selectedRow.after(clonedRow);
读了很多类似的问题后我认为.live可能有帮助，但不确定在哪里使用它。
EDIT:
我尝试删除live.
自动完成的新代码
$(function() {
(function( $ ) {
$.widget( "ui.combobox", {
_create: function() {
var self = this,
select = this.element.hide(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "";
var input = this.input = $( ".editableCombobox" ) // your input box
//.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 {
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;
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 ( $( this ).text().match( matcher ) ) {
this.selected = valid = true;
return false;
}
});
//if ( !valid ) {
// remove invalid value, as it didn't match anything
//$( 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 );
};
this.button = $( "<button type='button'> </button>" )
.attr( "tabIndex", -1 )
.attr( "title", "Show All Items" )
.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 ( $(this).prev().autocomplete( "widget" ).is( ":visible" ) ) {
$(this).prev().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
$(this).prev().autocomplete( "search", "" );
$(this).prev().focus();
});
},
destroy: function() {
this.input.remove();
this.button.remove();
this.element.show();
$.Widget.prototype.destroy.call( this );
}
});
})( jQuery );
$( "#combobox" ).combobox();
$( "#toggle" ).click(function() {
$( "#combobox" ).toggle();
});
});
在clone方法中绑定新添加的元素
var selectedRow = $('#contactGroup'+rowId);
var clonedRow = selectedRow.clone();
selectedRow.after(clonedRow);
$(('#contactGroup'+rowId) .editableCombobox).autocomplete( "search", "" );
