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。
但我的问题是在组合框中选择标签后立即显示id值而不是label值。
我创建了示例网格代码。请查看代码和图片。

出现问题的原因是您在网格中显示值。您需要为该列创建一个渲染器,该渲染器使用记录中的正确字段。
http://dev.sencha.com/deploy/ext-3.3.1/docs/?class=Ext.form.ComboBox
查找显示ComboBox in Grid
If using a ComboBox in an Editor Grid a renderer will be needed to show the displayField when the editor is not active. Set up the renderer manually, or implement a reusable render, for example:
Ext.util.Format.comboRenderer = function(combo){
return function(value){
var record = combo.findRecord(combo.valueField, value);
return record ? record.get(combo.displayField) : combo.valueNotFoundText;
}
}
您的代码在属性列表末尾也有很多额外的逗号。这甚至都不会在IE中解析,我从你发布的代码中删除它们。
