</p><!-- /.modal -->
$(function() {
$('#modal-click-error').on('click', function() {
$('#myModal').modal('show');
$("#myModal .btn-primary").on('click', function() {
alert("提交");
});
});
});Problem repair
The above js code will be displayed every time the button is clicked. Add corresponding events for the submit button. Just modify it as follows:
$(function() {
$('#modal-click-error').on('click', function() {
$('#myModal').modal('show');
});
$("#myModal .btn-primary").on('click', function() {
alert("提交");
});
});The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
