I need to create a button that is invisible and will be triggered by a JavaScript function.
<asp:Button ID ="btnDummy1" runat="server" Visible ="true" OnClick="btnSubmit1_Click" width="0px" height="0px"/
Setting 'visible = false' doesn't work because the JavaScript won't recognize invisible content on the page. I've tried setting width=0 and height=0, but it still appears in Chrome. Any suggestions on what I should do?
Thank you in advance :)
An effective technique in ASP.Net is to apply a "hidden" class:
<asp:Button ID ="btnDummy1" runat="server" CssClass="hidden" />
This can be styled in your CSS file as follows:
.hidden { display: none; }
If you set the visibility to Hidden="True", the code will not run.
Instead, consider enclosing it in a <div> tag and using CSS to hide it:
<div style="display: none;">
<asp:Button ID ="btnDummy1" runat="server" OnClick="btnSubmit1_Click" />
</div>
By including the attribute style="display:none", you can effectively conceal the button until you decide to reveal it once more.
<asp:Button ID ="btnDummy1" runat="server" OnClick="btnSubmit1_Click" style="display:none"/>
What do you think of using
style="display:none"
in place of setting Visible = "true" for the button?
Is it possible to simply utilize a concealed form field in this scenario? This is typically the recommended approach for transmitting information.
For more information, check out
<asp:Button ID="btnMyOrders" runat="server" Text="my orders" CssClass="dropdown-item" OnClick="btnMyOrders_Click" Visible="False" />
For instance, within the Form() function:
By using btn.Visible = true; you can make it visible again.
When considering adding elements to your HTML document, it's important to question why you would include something like an invisible button.
HTML should be used solely for defining the semantics of your content. It should only consist of the actual content you want to display and additional information to explain that content's meaning - nothing related to appearance or behavior.
All styling and functionality concerns should be addressed using CSS and Javascript, never directly within the HTML itself.
If an element is required purely for JavaScript purposes, it should be dynamically added to the document through JavaScript code.
For instance, instead of including prev/next buttons for a JavaScript gallery directly in the HTML, you should just list the images and have the JS script handle the gallery's presentation and navigation buttons.
In your case, mentioning an invisible button with JavaScript actions in the HTML suggests that this element may not belong in the document at all.
