Often, IE7 is regarded less standards compliant than its open source alternatives. Accidentally I ran into a – at least for me – unknown feature in IE7 which proves that in some cases IE7 can be rather strict. Take this, a FORM without a submit-button, but with a BUTTON-button:
<form> <!-- a lot of code --> <button>fire!</button> </form>
Firefox just submits the form when you click the button. IE7 however does nothing! It appeared that IE7 only submits the form when the attribute type is specified as type=”submit”.
Cool! Seems logically in the end. Where are the times that Microsoft interpreted all your sloppy code?
Tested with a XHTML 1.0 Strict page with a FORM-element which included three BUTTON-buttons. I encountered no form submitting problems without the type attribute specified in FF 22.214.171.124 or in Opera 8.54 on Windows XP SP2. I didn’t test in IE6 or other exotic browsers.
