如何使用输入的表单数据的值更新 ASP.NET 文本框？ 下面的代码基本上是 modal dialog form sample from jQuery UI , 但带有 ASP.NET 文本框。 回发已触发，但文本框未更新。
回发后，我的测试框中没有值。我很确定这很容易，但我的大脑现在被阻塞了，想不通为什么。

最佳答案
dialog.close 函数在页面发布之前清除所有字段:
close: function () {
allFields.val('').removeClass('ui-state-error');
}
您可能应该将对 val('') 的调用移动到 dialog.open 中(如果它仍然提供预期的用户体验)。
