将jQuery自动完成应用于克隆元素

我正在使用jQuery自动完成function ，它可以与现有元素一起使用，但不能使用动态添加的元素。

这是我的自动完成代码（我稍微改了一下）

$(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 $( "
" ) .data( "item.autocomplete", item ) .append( "" + item.label + "" ) .appendTo( ul ); }; this.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); 

在阅读了许多类似的问题后，我认为.live可能有所帮助，但不确定在哪里使用它。

编辑：

我试过删除live 。

自动填充的新代码

 $(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 $( "
" ) .data( "item.autocomplete", item ) .append( "" + item.label + "" ) .appendTo( ul ); }; this.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(); }); }); 

在克隆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", "" );

据我所知，你不能在自动完成时使用’live’。

将自动完成选项放在期望将字段作为参数的函数中，您要在其上应用自动完成方法。

 function enable_autocomplete(InputField) { $(InputField).autocomplete({ source: availableTags }); } 

然后，在克隆字段后，使用克隆字段调用此函数。

 enable_autocomplete(ClonedField); 

我给你写了一个简单的例子，是什么让我更容易理解我想说的话;-)

编辑 ： 我已经根据jQueryUIs网站上的combobox示例编写了另一个示例。

你可以使用’live’，虽然这些天你应该使用’on’方法。

请参阅此主题以获取工作示例（包括使用’on’，如果您深入了解一些隐藏的答案）： 使用.live（）绑定jQuery UI自动完成
