我有一个使用updatepanel的用户控件。当页面首次加载按钮时，单击工作正常并且显示在DIV中......当我再次搜索并点击按钮时，单击事件不会触发，即使页面加载事件也未触发。当您输入邮政编码时，我使用谷歌地理编码找到最近的商店。我怀疑它是使用javascript或页面验证，不让按钮触发click事件。这是我的代码。

“我正在做的是，一旦用户输入邮政编码和文本框丢失焦点，我正在调用地理编码以在隐藏字段中准备好LAT和LNG值。一旦用户点击，点击事件就会在服务器上触发并显示结果使用RadiobuttonList。一旦用户选择一个收音机，一个div显示他们选择的商店的详细信息。现在让我们说如果他们不选择一个收音机并尝试输入差异邮政编码，然后按钮点击不工作。但是如果他们选择一个收音机，然后尝试差异邮政编码，按钮点击工作正常..
任何人都知道为什么会这样......

你是以错误的方式附加事件。
更新面板会进行部分页面回发，并且在手动刷新页面之前永远不会处于文档准备状态。
删除AttachEventAfterPostback并在pageLoad函数中编写代码，这样在每次部分回发后都会自动重新绑定每个东西
function pageLoad(sender,args){
address = $('.ClickAndCollectTextBox').val();
if (address.length != 0) {
checkAddress(address);
getLatLong(address, region);
}
$('.ClickAndCollectTextBox').on('blur', function () {
address = $('.ClickAndCollectTextBox').val();
if (address.length != 0) {
checkAddress(address);
getLatLong(address, region);
}
});
}
