我在Sencha touch 2.1中创建了一个选择器。我的数据显示正常。我想要禁用特定值而不是所有值,以便如果我选择该值并单击“ doneButton ”,则不应该这样做。
示例:
function loadPicker(paramName, valueSet) {
Ext.Viewport.remove(Ext.getCmp(paramName + 'Pickerfield'), true);
if (!paramName.picker) {
paramName.picker = Ext.Viewport.add({
xtype: 'picker',
id: paramName + 'Pickerfield',
useTitles: true,
slots: [{
name: paramName,
title: paramName,
data: valueSet
}],
doneButton: {
listeners: {
tap: function(button, event, eOpts) {
var selectedPacingModeValue =
Ext.getCmp(paramName + 'Pickerfield').getValue()[paramName];
sendSetPendingRequest(paramName, selectedPacingModeValue);
}
}
}
});
}
}
让我们选择这些是我的选择器字段中的值。我在选择一个值并单击“ doneButton ”时正在做什么,我在文本字段中显示该值。我想要的是,如果我选择“选项2 ”并单击“ doneButton ”,则选项2 不应显示在文本字段中,而是在文本字段操作中选择和显示的所有其他值应该有效。

您可以获取所选记录并在点击完成按钮后检查该标记,然后移至文本框(或不)。
