我正在尝试提交一个我已经工作过的表单,但现在已经对其进行了修改以包含一个模态 jQuery UI 框,以便在用户按下“继续”之前它不会提交。我遇到了各种各样的问题,包括让表单保持直到按下该按钮,但我想我已经找到了解决方案,但是实施它,我得到了一个 SyntaxError ,我找不到它的来源.
在 kevin B 的帮助下,设法找到了表单正在提交的答案,但返回的 JSON 响应的格式并不完全正确。响应是表单没有被提交,所以这个问题仍然存在。
所以用提供的反馈更新了代码,现在需要找出为什么表单没有提交。我知道它与第二个功能有关,即没有识别已按下提交按钮,因此需要知道如何提交该表单数据而无需再次提交表单。
以下是新代码:
function submitData() {
$("#submitProvData").submit(function(event) { 
    event.preventDefault();
    var gTotal, sTotal, dfd;
    var dfd = new $.Deferred();
    $('html,body').animate({ scrollTop: 0 }, 'fast');
    $("#submitProvData input").css("border", "1px solid #aaaaaa");
    $("#submitProvData input[readonly='readonly']").css("border", "none");
    sTotal = $('#summaryTotal').val();
    gTotal = $('#gptotal').val();
    if(gTotal !== 'sTotal'){
        $("#newsupinvbox").append('<div id="newsupinvdiagbox" title="Warning - Totals do not match" class="hidden"><p>Press "Continue", to submit the invoice flagged for attention.</p> <br /><p class="italic">or</p><br /> <p>Press "Correct" to correct the discrepancy.</p></div>') //CREATE DIV
        //SET
        $("#newsupinvdiagbox").dialog({
            resizable: false,
            autoOpen:false,
            modal: true,
            draggable: false,
            width:380,
            height:240,
            closeOnEscape: false,
            position: ['center',20],
            buttons: {
                'Continue': function() {
                    $(this).dialog('close');
                    reData();
                }, // end continue button
                'Correct': function() {
                    $(this).dialog('close');
                        return false;
                    } //end cancel button
                }//end buttons
            });//end dialog
            $('#newsupinvdiagbox').dialog('open');
        }
        return false;
    });
}
function reData() {
    console.log('submitted');
    $("#submitProvData").submit(function(resubmit){
        console.log('form submit');
        var formData;
        formData = new FormData($(this)[0]);
        $.ajax({
            type: "POST",
            url: "functions/invoicing_upload_provider.php",
            data: formData,
            async: false,
            success: function(result) {
                $.each($.parseJSON(result), function(item, value){
                    if(item == 'Success'){    
                        $('#newsupinv_window_message_success_mes').html('The provider invoice was uploaded successfully.');
                        $('#newsupinv_window_message_success').fadeIn(300, function (){
                            reset();
                        }).delay(2500).fadeOut(700);
                    } else if(item == 'Error'){      
                        $('#newsupinv_window_message_error_mes').html(value);
                        $('#newsupinv_window_message_error').fadeIn(300).delay(3000).fadeOut(700);
                    } else if(item == 'Warning'){      
                        $('#newsupinv_window_message_warning_mes').html(value);
                        $('#newsupinv_window_message_warning').fadeIn(300, function (){
                            reset();
                        }).delay(2500).fadeOut(700);
                    } 
                });
            },
            error: function() {
                $('#newsupinv_window_message_error_mes').html("An error occured, the form was not submitted");
                $('#newsupinv_window_message_error').fadeIn(300);
                $('#newsupinv_window_message_error').delay(3000).fadeOut(700);
            },
            cache: false,
            contentType: false,
            processData: false
        });
    });
