jQuery Forum

I had the same problem a couple years ago and struggled with it.  Unfortunately, I don't remember much about it.

Are you using
tinyMCE.triggerSave(true, true); // moves iFrame content into input or textarea

If that doesn't fix it, post some relevant code.

I am using "tinyMCE.triggerSave(true, true);" before the form submit.

And I am using jQuery validation plugin for the form validation ( in http://jqueryvalidation.org/). And the my code is as follows (This works perfect in IE8+ and Google Chrome):

//form submit function and the form validation
jQuery('#frm').submit(function() {
            // update underlying textarea before submit validation
            tinyMCE.triggerSave(true,true);
        }).validate({
            errorClass: 'error',
            rules: {
                //validation rules
                'users':'required'
            },
            submitHandler: function(form) {
                //submit confirmatiom   
                if (confirm('Are you sure you want to submit the form?' ){
                    $('#frm').ajaxSubmit({
                        beforeSubmit:   beforeFormSubmit, // pre-submit callback
                        success:        afterSubmit  // post submit callback
                    });
                    return false;
                }
            }
});

//pre-submit callback
function beforeFormSubmit(){
    $('#btn_submit').val("Saving...");
    $.blockUI(); //block ui plugin
}

//post submit callback
function afterSubmit(response, status)  {
    if(status == 'success') {
            $('#message_box').html("Success.")
    }else{
            $('#message_box').html("Error : "+response)
    }
    $.unblockUI(); 
}

Your code looks OK to me. Its similar to my Validation plug-in code, as I'm sure everyone has it in similar form.  The major difference is I don't use Validation to submit. I use the jQuery Form plug-in to manage the submit. It handles all the special cases like submitting images versus text.

Sorry I can't see the problem. Since Validation is a plug-in, post the problem at the Plug-in Forum. Maybe someone there has run into this problem.
