在_doPostBack JavaScript对象预期的错误（''，''） [英] JavaScript Object Expected error in _doPostBack('','')

问题描述

我不断收到我的网页脚本中的预期的目标错误，当我点击按钮。
我用火错误调试，并传递到JavaScript方法的id是正确的ID和的document.getElementById（一）查找按钮。误差保持在 _doPostBack 发生。这能造成的，因为该按钮是在GridView单元格的模式弹出里面，在GridView是一个更新面板内。

I keep getting the 'Object Expected' error within my page script when I click the button. I've debugged using fire-bug and the id passed to the JavaScript method is the correct id and document.getElementById(a) finds the button. The error keeps occurring in the _doPostBack. Can this be caused because the button is inside a modal popup in a gridview cell, and the gridview is inside a update panel.

有关完整code请参阅本previous问题<一href=\"http://stackoverflow.com/questions/10969690/button-click-event-on-modal-popup-inside-a-grid-view-not-firing\">event没有发射我张贴和解决。

For complete code please see this previous question event not firing I posted and resolved.

我现在还在使用JavaScript的原因是没有这并没有发生在GridView.RowCommand后返回的事件。

The reason I'm still using the JavaScript is the Post-Back event in the GridView.RowCommand did not occur without this.

有没有来替代？

在code：

function addAcc(a) {
        var btn = document.getElementById(a); //get the button, not necessary but safer
        alert(a); //To see the button id
        _doPostBack(btn.id, ''); //do the postback so RowCommand Fires in code behind
    };

＆LT; ASP：按钮的ID =btnAddAcc=服务器文本=添加帐户
                                                        的OnClientClick =JavaScript的：addAcc（this.id）/＆GT;

谢谢你的任何解决方案和想法。
问候

Thank you for any solutions and ideas. Regards

推荐答案

在dopostback方法是用两个下划线而不是一个，像

the dopostback method is with two underscores not one, like

__doPostBack

所以你的电话是这样的：

so your call is like:

__doPostBack(btn.id, '');

而不是

_doPostBack(btn.id, '');
