Jquery Radio Button uncheck radio button, but should not clear value part

问题

I am trying to clear my form fields on reset button using following code

$(':input',formId).not(':button, :submit, :reset, :hidden').val('').prop('checked', false).removeAttr('selected');

Now my Radio button is getting unchecked, but value set in radio button is also getting cleared.

I want only to uncheck it, But value of the radio button should be available.

回答1:

You can use reset() function here:

formId.reset();

reset resets the form to its initial state.

回答2:

don't clear the value, i.e. remove .val(''). This is setting your value to blank. so you want to do this

$(':input[type!=checkbox]',formId).not(':button, :submit, :reset, :hidden').val('')
        .removeAttr('selected');

then this

$(':input[type=checkbox]',formId).not(':button, :submit, :reset, :hidden')
        .removeAttr('checked');

you don't need .removeAttr('selected'). Chekboxes only have a checked attribute, see w3c here
