是否可以在标签的标题中显示组合框(更好的是,如果它将是extjs组合)?
我创建了an example on jsfiddle但是存在这样的问题:
1.无法显示组合选项列表(鼠标单击不起作用)
2.标签的高度不正确(我想这可以通过将高度应用于组合来修复)。
示例代码:
new Ext.TabPanel({
renderTo: 'tab-with-combo',
activeTab: 0,
items:[
{
title: 'First tab ' +
'<select>' +
'<option>Option 1</option>' +
'<option>Option 2</option>' +
'</select>'},
{title: 'Second tab'}
]
});

回答你的问题:
Tabpanel
组件preventDefault
点击标签处的事件,因此我们需要修改onStripMouseDown
方法。
如果我们在title
属性中定义一些内容,那么extjs会将它放在具有特殊样式的span.x-tab-strip-text
html元素中。所以我们需要在选项卡中将此元素后面的组合框附加。
代码:
new Ext.TabPanel({
renderTo : 'tab-with-combo',
activeTab : 0,
items : [{
title : 'First tab ',
listeners : {
afterrender : function (panel) {
//the needed tabEl
var tabEl = panel.findParentByType('tabpanel').getTabEl(panel);
var tabStripInner = Ext.fly(tabEl).child('span.x-tab-strip-inner', true);
//we need that for have the combobox in the same line as the text
Ext.fly(tabStripInner).child('span.x-tab-strip-text', true).style.float = 'left';
//create the combobox html element
var combo = document.createElement("select");
var opt1 = document.createElement("option");
opt1.innerHTML = 'Option 1';
var opt2 = document.createElement("option");
opt2.innerHTML = 'Option 2';
combo.appendChild(opt1);
combo.appendChild(opt2);
combo.style.float = 'left';
//add the combobox to the tab
tabStripInner.appendChild(combo);
}
}
}, {
title : 'Second tab'
}
],
//this is the tab's click handler
onStripMouseDown : function (e) {
if (e.button !== 0) {
return;
}
var t = this.findTargets(e);
if (t.close) {
//preventDefault needed to move here
e.preventDefault();
if (t.item.fireEvent('beforeclose', t.item) !== false) {
t.item.fireEvent('close', t.item);
this.remove(t.item);
}
return;
}
if (t.item && t.item != this.activeTab) {
this.setActiveTab(t.item);
}
},
});

感谢@ Alexander.Berg的回答,这个工作正常(例如here):
var comboId = Ext.id();
new Ext.TabPanel({
cls: 'tab-panel-with-combo',
renderTo: 'tab-with-combo',
activeTab: 0,
items:[
{
title: '<div class="tab-title" style="float: left; padding-right: 5px;">First tab with a long name</div> ' +
'<div style="float: right;" id="' + comboId + '" ></div>',
closable: true,
html: 'Content of the first tab'
},
{
title: '<div class="tab-title">Second tab</div>',
closable: true,
html: 'Content of the second tab'
}
],
listeners: {
afterrender: function() {
var store = new Ext.data.ArrayStore({
fields: ['abbr', 'case_name'],
data : [
['one', 'Case #1'],
['two', 'Case #2'],
['three', 'Case #3']
]
});
new Ext.form.ComboBox({
store: store,
displayField:'case_name',
editable: false,
typeAhead: false,
selectOnFocus:false,
mode: 'local',
forceSelection: true,
triggerAction: 'all',
emptyText:'Select a case...',
renderTo: comboId
});
}
}
});
