OnClientClick does not works on asp.net LinkButton
提问by Abbas
I have an asp.net linkbutton, which contains the OnClientClickproperty, however the function within the OnClientClicknever gets called, it directly jumps to OnClickfunction.
Below are the 2 ways I am using LinkButton as:
我有一个linkbutton包含OnClientClick属性的 asp.net ，但是OnClientClick从未调用过其中的函数，它直接跳转到OnClick函数。
以下是我使用 LinkButton 的两种方式：
<asp:LinkButton ID="btn" CssClass="button" Text="Browse Thumbnail" runat="server"
OnClientClick="return confirm('Are you sure you want to delete?');">
</asp:LinkButton>
and:
和：
<asp:LinkButton ID="lnkDelete" runat="server"
OnClientClick="return confirm('Are you sure you want to delete this slide?');"
CommandName="DeleteThumbnail" CommandArgument='<%# Container.DataItemIndex %>'>
<asp:Image ImageUrl="~/images/delete.gif" ID="imgDelete" runat="server"></asp:Image>
</asp:LinkButton>
Both of the approaches does not works.
这两种方法都行不通。
Can anyone please provide some solution for the same.
任何人都可以为此提供一些解决方案。

There is most probably some other page element that is preventing this event from being fired.
很可能有一些其他页面元素阻止了这个事件被触发。
Do you have any other page elements that might interfere? Have you tried removing all other page elements but this one? Do you have some AJAX calls that might interfere? Have you tried this with a simple html element (not asp.net)?
您还有其他可能会干扰的页面元素吗？您是否尝试删除除此之外的所有其他页面元素？您是否有一些可能会干扰的 AJAX 调用？你有没有用一个简单的 html 元素（不是 asp.net）试过这个？
You are most probably doing everything fine in your link button but it seems like problem is elsewhere.
您很可能在链接按钮中一切正常，但似乎问题出在其他地方。

OnClientClick="javascript:return confirmAction();"
function confirmAction() {
if(confirm('Are you sure you want to delete?')) {
// you clicked the OK button.
// you can allow the form to post the data.
return true;
}
else {
return false;
}
}
implement the Onclick on the server side
在服务器端实现 Onclick
protected void lnkdelete_Click(object sender, EventArgs e)
{
}
and if you dnt want to call server method use this
如果您不想调用服务器方法，请使用它
OnClientClick="javascript:confirmAction(); return false;"

Place it in single quotes like below,
将它放在单引号中，如下所示，
<asp:LinkButton ID="btn" CssClass="button" Text="Browse Thumbnail" runat="server" OnClientClick="return confirm('Are you sure you want to delete?');"></asp:LinkButton>

Use like this
像这样使用
function Navigate()
{
javascript: window.open("microsoft.com");
return false;
}
and on clientclick as follows
并在客户端单击如下
OnClientClick="return javascript:Navigate()"
or even
甚至
function Navigate()
{
window.open("microsoft.com");
return false;
}
OnClientClick="return Navigate()"

There is no problem with your OnClientClickmethod it should prompt confirm window. but you haven't specify the onclick event of the link button. So you will not able to get the event from code behind.
你的OnClientClick方法没有问题，它应该提示确认窗口。但是您还没有指定链接按钮的 onclick 事件。因此，您将无法从后面的代码中获取事件。
