ExtJS4.0中的多选与复选框的组合可以通过添加几行代码来实现。
基本上,您需要利用现有的 css 类,该类在选择和取消选择项目期间应用,并相应地推送图像(复选框图像)。
"x 绑定列表项" and "x-boundlist-选定" 是从 ext-all.css 中获取的类。
<style>
.x-boundlist-item img.chkCombo {
background: transparent url(/lib/extjs-4.1.0/resources/themes/images/default/menu/unchecked.gif);
}
.x-boundlist-selected img.chkCombo{
background: transparent url(/lib/extjs-4.1.0/resources/themes/images/default/menu/checked.gif);
}
</style>
<head>
Ext.create('Ext.form.ComboBox', {
id: 'BCCAddress',
name: 'BCCAddress',
maxHeight: 150,
width: 210,
multiSelect: true,
emptyText : "Select Bcc email addresses",
renderTo: 'extBCCAddress',
store: myArrayStore,
displayField: 'fieldName',
valueField: 'fieldName',
forceSelection: true,
editable: false,
mode: 'local',
triggerAction: 'all',
listConfig : {
getInnerTpl : function() {
return '<div class="x-combo-list-item"><img src="' + Ext.BLANK_IMAGE_URL + '" class="chkCombo-default-icon chkCombo" /> {fieldName} </div>';
}
}
});
