How to call html button onclick javascript function with aspx parameter?

Question

I need to pass parameters from repeater to javascript function. But I can't do it like this:

     onclick="myFunction(<%# ((myObject)Container.DataItem).myValue) %>)" 

It says syntax error.

I need to call myFunction(myValue) javascript function. And the myValue have to come from

     <%# ((myObject)Container.DataItem).myValue) %>

What is the correct way to do this ?

Answer 1

如果您想将所有内容都写在标记中（而不是在rowdatabound或后面的代码中的某处），则可以使用以下语法：

onclick = '<%# "myFunction(" + Container.DataItemIndex + ")" %>'

Answer 2

What you need to do is add a couple of quotes:

onclick="myFunction("<%# ((myObject)Container.DataItem).myValue %>")"

This should work with what you are trying to achieve.

Answer 3

Try this if you pass string

onclick='<%# string.Format("myFunction(\"{0}\")",((myObject)Container.DataItem).myValue)%>'

otherwise use following...

onclick='<%# string.Format("myFunction({0})",((myObject)Container.DataItem).myValue)%>'

Answer 4

尝试从服务器端添加onclick，

Control.Attributes.Add("onclick",((myObject)Container.DataItem).myValue)

Answer 5

Use something like this.Modify this according to your requirement.

protected void Gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
 {

var jsFunction = String.Format("Javascriptfunctionname('{0}','{1}');", parameter1, parameter2);
Gridcontrol.Attributes.Add("onclick", jsFunction);

}

Hope this will help you.
