按下回车键时调用onClick事件上的特定按钮C＃

Question

I'm trying to get a specific asp:button onclick event to fire when I press the enter key in a specific asp:textbox control.

The other factor to be taken into account is that the button is within a asp:Login control template.

I've no idea how to do this, suggestions on a postcard please.

Answer 1

您可以查看面板控件的DefaultButton属性。

Answer 2

You could set the DefaultButton property on the form. Either as an attribute of the form tag in your markup DefaultButton = "btnSubmit" or using something like this in your code-behind:

Page.Form.DefaultButton = "btnSubmit"

Answer 3

它的HtmlForm.DefaultButton

Answer 4

You need to do it with javascript. It's really easy with jQuery.

You can do something like (off the top of my head, not tested):

$('#myTextBox').keypress(function(e){
    if(e.which == 13)
        $('#myBtn').click();
});

Edit: Be aware that although jQuery works exceptionally cross browser, there are some quirks with keypress described here .

Whoops i didnt see you said the "enter key" i thought you said "any key", yeah in that case use DefaultButton on asp:panel
