In stead of running the xhr in the onclick event, run a regular asynchronous call instead and return false to stop the submit. Then when the xhr finishes you either submit the form using js or show some feedback about what was wrong.

In that case you don't even need a form, much less a submit button. Just use onclick. Hans-Georg

Not weird at all. its either onclick="return false;" or onclick="return checkForm();" where checkform = function(){return false;}

If I do document.myForm.submit() then I got php script in my URL and no anything on screen . This php script is form "myForm" action. If I try to document.getElementById("myInput").submit() where myInput is input with submit button then got document.getElementById("myImput").submit is not a function what is the solution? |
