在每个回发页面上打开一个新选项卡 [英] on every postback page opens in a new tab
问题描述
全部，
我的页面中有一个奇怪的问题。我有一个名为Print的按钮。我希望报告应该出现在新标签中，所以我在按钮的onClientClick上写了一些javascript。哪个效果很好，没有任何问题。
但是当用户再次回到原始页面时，问题就开始了，现在我在这里有几个导致回发的控件。比如说它是一个下拉列表。因此，每当用户更改下拉项时，它会导致回发，这很好，但每次在每次回发时都会打开一个新选项卡。
希望我有问题...
任何帮助??
这是一个代码：
HI all,
I have a weird problem in my page. I have a button called Print. I wanted report should come in a new tab, so i wrote some javascript on button's onClientClick. Which works great with no problem at all.
But problem starts now when user comes back on original page again, now here i have several controls which cause postback. Say for example its a dropdownlist. so whenever user changes dropdown item it causes postback which is fine but everytime it opens a new tab on every postback.
hope I am clear in question...
Any help??
Here is a code:
<asp:button ID="btnPrint" runat="server" Text = "Print" OnClick="btnPrint_Click" onClientClick="aspnetForm.target='_blank'" />
推荐答案
在页面加载事件检查IsPostBack并根据它加载你的设置。
Hi,
On page load event checkIsPostBackand load you settings according to that.
我只是清除onLoad上的目标
i just clear the target on onLoad like this
opener.document.getElementById('aspnetForm').target = '';
和这很有效....： - ）
and this works great....:-)
首先感谢Hiren，我和li有同样的问题ke你但是使用你的解决方案我把它整理出来
in aspx;
in body section
写下来以下
first of all thanks Hiren, i had a same problem as like you but using your solution i sort it out
in aspx;
inside body section
write the following
<body onload="fixform()">
然后写一个javascript
then write a javascript
<script type="text/javascript">
function fixform()
{
document.getElementById("Form1").target = '';
}
记住你已经设置了target ='_ blank'onClientClick
for viz。：
remember you have set target ='_blank' onClientClick
for viz.:
<asp:button id="btnPrint" runat="server" text="Print" onclick="btnPrint_Click" onclientclick="Form1.target='_blank'" xmlns:asp="#unknown" />
