问题描述
我正在使用带有标签和id值的ext js auto complete组合框，它完美地显示了前面的标签，并将id作为值。
I am using ext js auto complete combo box with label and id values, It is perfectly showing the label in front and getting id as a value.
但是，我的问题是在组合框中选择标签后立即显示id值而不是标签值。
But my problem is after selecting the label in combo box it immediately showing the id value instead of label value.
我已经创建了示例网格代码。请查看代码和图片。
I have created example grid code. Please view the code and image.

推荐答案
发生问题是因为您在网格中显示值。您需要为该列创建一个使用记录中正确字段的渲染器。
Your problem occurs because you are displaying the value within a grid. You need to create a renderer for that column which uses the correct field from the record.
查找网格中的组合框
如果在编辑器网格中使用ComboBox，编辑器不活动时，需要渲染器显示displayField。手动设置渲染器，或实现可重用的渲染，例如：
Ext.util.Format.comboRenderer = function(combo){
return function(value){
var record = combo.findRecord(combo.valueField, value);
return record ? record.get(combo.displayField) : combo.valueNotFoundText;
}
}
您的代码还遭受了大量额外的逗号财产清单的结尾。这甚至不会在IE中解析，我将其从您发布的代码中删除。
Your code was also suffering from lots of extra commas at the end of property lists. That will not even parse in IE, I removed them from the code you posted.
