The trigger function returns true before the form is submitted.

Look directly at the code

The code copy is as follows:

<form id="payForm" action="yeepay.html" target="_blank" method="post" onsubmit="return checkform();">

The onsubmit function in the example is a function triggered before form submission

The code copy is as follows:

function checkform() {

var value = $("input[name='payWay']:checked").val();

if (value == 1) {

$("#alipayment").submit();

return false;

}

return true;

}

If the form is returned, it will be submitted, otherwise it will not be submitted
