将多个eval参数传递给ASPX中的javascript函数 [英] Passing multiple eval parameters to a javascript function from ASPX

问题描述

大家好，

我已经知道它如何使用单个参数。可以使用两个参数。



我尝试过：

Hi All,
I already know how it works with a single parameter.Is it possible with two parameters.

What I have tried:

OnClientClick='<%# Eval("psid", "window.open(\"add.aspx?cid={0}\", null,\"scrollbars=yes,top=10,left=10\", \"true\");") %>'

一个参数是文本框值。提前谢谢

One parameter is a textbox value.Thanks in advance

推荐答案

从你的代码看，你看起来并没有将值传递给任何函数，所以我担心这是不可能的，虽然我不是Javascript中的PRO。

但是，你可以随时传递所需数量的参数使用 Eval 的函数。



在这种情况下，你的代码应该类似于以下内容 -

From your code it looks you are not exactly passing values to any function, so I afraid that's not possible, although I am not a PRO in Javascript.
However, you can always pass as many parameters required to a function using Eval.

In that case, your code should look something like following-

OnClientClick='<%# "MyFunctionName(" +Eval("FirstParameter") + ","+Eval("SecondParameter")+" );" %>'

看起来你想要打开一个新窗口，你可以在里面写功能也很好。



如果不清楚或需要进一步的帮助，请告诉我。



谢谢：）

It looks like you want to open a new window as well, which you can write inside the function as well.

Please let me know if something is not clear or if you need further help.

Thanks :)

通过两个参数如

Pass two params like

add.aspx?param1=123&param2=456

但是如果第二个参数需要是文本框的值，你可能最好不要使用OnClientClick而是纯javascript在页面上。你需要像

However if the second parameter needs to be the value of a textbox you're probably better not using OnClientClick but pure javascript on the page. You'll need something like

<asp:TextBox ID="TextBox1" runat="server" />
<asp:Button runat="server" ID="btn" OnClientClick='<%# string.Format("window.open(\"add.aspx?cid={0}&param2=\" + document.getElementById(\"{1}\").value, null,\"scrollbars=yes,top=10,left=10\", \"true\");", Eval("psid"), Container.FindControl("TextBox1").ClientID) %>' Text="click"/>

如何找到文本框以获取其ID取决于文本框的位置和文本框的类型，这两者都不是你所说的。

How you find the textbox to get its id depends where the textbox is though and what kind of textbox it is, neither of which you've said.
