一、ExtJs4.2中Tab选项卡的右击关闭其它和关闭当前功能不准确的解决方法
二、找到ux目录下的TabCloseMenu.js文件,将内容替换成下面代码。
三、代码:
/** * Plugin for adding a close context menu to tabs. Note that the menu respects * the closable configuration on the tab. As such, commands like remove others * and remove all will not remove items that are not closable. */ Ext.define('Ext.ux.TabCloseMenu', { alias: 'plugin.tabclosemenu', mixins: { observable: 'Ext.util.Observable' }, /** * @cfg {String} closeTabText * The text for closing the current tab. */ closeTabText: 'Close Tab', showCloseOthers: true, closeOthersTabsText: 'Close Other Tabs', /** * @cfg {Boolean} showCloseAll * Indicates whether to show the 'Close All' option. */ showCloseAll: true, closeAllTabsText: 'Close All Tabs', /** * @cfg {Array} extraItemsHead * An array of additional context menu items to add to the front of the context menu. */ extraItemsHead: null, /** * @cfg {Array} extraItemsTail * An array of additional context menu items to add to the end of the context menu. */ extraItemsTail: null, //public constructor: function (config) { this.addEvents( 'aftermenu', 'beforemenu'); this.mixins.observable.constructor.call(this, config); }, init: function (tabpanel) { this.tabPanel = tabpanel; this.tabBar = tabpanel.down("tabbar"); this.mon(this.tabPanel, { scope: this, afterlayout: this.onAfterLayout, single: true }); }, onAfterLayout: function () { this.mon(this.tabBar.el, { scope: this, contextmenu: this.onContextMenu, delegate: '.x-tab' }); }, onBeforeDestroy: function () { Ext.destroy(this.menu); this.callParent(arguments); }, // private onContextMenu: function (event, target) { var me = this, menu = me.createMenu(), disableAll = true, disableOthers = true, tab = me.tabBar.getChildByElement(target), index = me.tabBar.items.indexOf(tab); this.item = me.tabPanel.getComponent(index); me.selectedTab = me.tabPanel.getComponent(index); menu.child('*[text="' + me.closeTabText + '"]').setDisabled(!me.item.closable); if (me.showCloseAll || me.showCloseOthers) { me.tabPanel.items.each(function (item) { if (item.closable) { disableAll = false; if (item != me.item) { disableOthers = false; return false; } } return true; }); if (me.showCloseAll) { menu.child('*[text="' + me.closeAllTabsText + '"]').setDisabled(disableAll); } if (me.showCloseOthers) { menu.child('*[text="' + me.closeOthersTabsText + '"]').setDisabled(disableOthers); } } event.preventDefault(); me.fireEvent('beforemenu', menu, me.item, me); menu.showAt(event.getXY()); }, createMenu: function () { var me = this; if (!me.menu) { var items = [{ text: me.closeTabText, scope: me, handler: me.onClose }]; if (me.showCloseAll || me.showCloseOthers) { items.push('-'); } if (me.showCloseOthers) { items.push({ text: me.closeOthersTabsText, scope: me, handler: me.onCloseOthers }); } if (me.showCloseAll) { items.push({ text: me.closeAllTabsText, scope: me, handler: me.onCloseAll }); } if (me.extraItemsHead) { items = me.extraItemsHead.concat(items); } if (me.extraItemsTail) { items = items.concat(me.extraItemsTail); } me.menu = Ext.create('Ext.menu.Menu', { items: items, listeners: { hide: me.onHideMenu, scope: me } }); } return me.menu; }, onHideMenu: function () { var me = this; me.item = null; me.fireEvent('aftermenu', me.menu, me); }, onClose: function () { this.tabPanel.remove(this.selectedTab); }, onCloseOthers: function () { this.doClose(true); }, onCloseAll: function () { this.doClose(false); }, doClose: function (excludeActive) { var items = []; this.tabPanel.items.each(function (item) { if (item.closable) { if (!excludeActive || item != this.selectedTab) { items.push(item); } } }, this); Ext.each(items, function (item) { this.tabPanel.remove(item); }, this); } });
