asp.net mvc中的ExtJs网格错误

Question

我仍然需要您的帮助，更具体地说，是ExtJS网格的实现。我不能让它工作。我有一个视图，它用更多的参数进行搜索，然后控制器将进行动作研究，当加载页面时，我设置后者的控件，然后我发布我通过其搜索的动作。代码如下：

我已经测试了javascript调试器，并在进入debug extjs网格时加载页面，即使我单击搜索按钮以记事本格式向后搜索查询的内容，并且我甚至没有进入debugger JavaScript。

我可以帮助你理解为什么，我尝试了几个extjs的例子，但不起作用。

谢谢

Answer 1

首先，您应该使用浏览器来确保您的asp.net应用程序返回正确的格式。

当您百分之百确定它确实如此时，请检查您的ExtJs代码。

一种通用的答案，但就像Thevs指出的那样，你不应该发布如此庞大的代码。

此外，您是否能够发布您的asp.net应用程序返回的xml或json，这将有所帮助。

Answer 2

大家好，感谢你的回复，我解决了问题，我给了他来自json extjs的正确数据。
