推荐答案

_dopostback 用于执行来自javascript的PostBack类似于 document.getElementById（'buttonID'）。click（）; 通常我们使用这些技术强制执行回发。

例如，您已从页面打开弹出窗口，并在弹出控件上执行一些数据保存操作。现在您要更新您的父页面Listview / Gridview / repeater以重新绑定。然后你可以使用 _dopostback 或 document.getElementById（'buttonID'）。click（）; 执行回发并在按钮点击事件上重新加载所需数据。

Hi,
_dopostback is used to perform a PostBack from javascript and is similar to document.getElementById('buttonID').click(); Normally we use these techniques to forcefully perform a post back.
An example is you have open a popup from your page and on the popup control you perform some data save operations. Now you want to update your parent page Listview/Gridview/repeater to rebind. Then you may use _dopostback or document.getElementById('buttonID').click(); perform a postback and on the button click event reload the desired data.
