对于tabpanel中的每个标签,我有一个浮动面板位于固定位置。当我切换标签时,我需要将相应的浮动面板放在前面。但是,tabchange事件仅在第一次触发时触发。单击选项卡时如何捕获此tabchange或其他类似事件?
Alexey,这是我的示例代码,其中包含更具体的问题:
Ext.onReady(function() {
panel1 = Ext.create('Ext.panel.Panel', {
title: 'title1', width: 800, height: 50,
listeners: { 'beforeshow': { fn: function() {
console.log("beforeshow on title1");
}, scope: this, single: true } }
});
panel2 = Ext.create('Ext.panel.Panel', {
title: 'title2', width: 800, height: 50,
listeners: { 'beforeshow': { fn: function() {
console.log("beforeshow on title2");
}, scope: this, single: true } }
});
panel3 = Ext.create('Ext.panel.Panel', {
title: 'title3', width: 800, height: 50,
listeners: { 'beforeshow': { fn: function() {
console.log("beforeshow on title3");
}, scope: this, single: true } }
});
var tabpanel = Ext.createWidget('tabpanel', {
renderTo: document.body,
activeTab: 0,
width: 800, height: 50, plain: true,
items: [panel1, panel2, panel3],
listeners: {
'tabchange': { fn: function() {
console.log("tabchange");
}, scope: this, single: true }
}
});
});
“tabchange”消息只打印一次。我真正想要的是每次点击标签时都会显示“在......之前”的消息。
Leoh,你是男人!事实证明我的代码中的问题是“fn”。通过删除“fn”,“scope”和“single”,以下代码可以完美地运行。我不知道为什么。有人可以解释一下吗?
Ext.onReady(function() {
panel1 = Ext.create('Ext.panel.Panel', {
title: 'title1', width: 800, height: 50,
listeners: { 'beforeshow': function() { console.log("beforeshow on title1"); } }
});
panel2 = Ext.create('Ext.panel.Panel', {
title: 'title2', width: 800, height: 50,
listeners: { 'beforeshow': function() { console.log("beforeshow on title2"); } }
});
panel3 = Ext.create('Ext.panel.Panel', {
title: 'title3', width: 800, height: 50,
listeners: { 'beforeshow': function() { console.log("beforeshow on title3"); } }
});
var tabpanel = Ext.createWidget('tabpanel', {
renderTo: document.body,
activeTab: 0,
width: 800,
height: 50,
plain: true,
items: [panel1, panel2, panel3],
listeners: {
'tabchange': function() {
console.log("tabchange");
}
}
});
});

请将功能附加到事件标签页
Ext.onReady(function () {
panel1 = Ext.create('Ext.panel.Panel', {
title: 'title1'
});
panel2 = Ext.create('Ext.panel.Panel', {
title: 'title2'
});
panel3 = Ext.create('Ext.panel.Panel', {
title: 'title3'
});
var tabpanel = Ext.createWidget('tabpanel', {
renderTo: document.body,
activeTab: 0,
width: 800,
height: 50,
plain: true,
items: [panel1, panel2, panel3],
listeners: {
'tabchange': function (tabPanel, tab) {
console.log(tabPanel.id + ' ' + tab.id);
}
}
});
});

您可以尝试在更改标签后显示的面板上使用beforeshow事件
