I have some radio buttons and I want one of them to be set as selected by default when the page is loaded. How can I do that?
<input type="radio" name="imgsel" value="" />

Give people control and align with their expectations (Good): It is better to have a selected radio button by default, given that people cannot deselect and set the button back to its original state once one has been selected. A default selection sets the correct user expectation.
You can use the jQuery prop() method to check or uncheck radio button dynamically such as on click of button or an hyperlink etc. The prop() method require jQuery 1.6 and above.
XHTML solution:
<input type="radio" name="imgsel" value="" checked="checked" /> Please note, that the actual value of checked attribute does not actually matter; it's just a convention to assign "checked". Most importantly, strings like "true" or "false" don't have any special meaning.
If you don't aim for XHTML conformance, you can simplify the code to:
<input type="radio" name="imgsel" value="" checked> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
