Question

我似乎无法在我的代码中找到问题。我想在php文件中验证触发jquery通知插件'toastr'，但是，php echo继续将php文件消息状态发布到新选项卡，而不是。我做错了什么，如何让消息显示在通知中呢？我的学校网站的实时版本位于：Wright State University BMES Site，在提交联系我们表单时可以复制问题。提前谢谢你：）

HTML：

<form action=send-contact.php method=post data-show-errors="true" class=contact-form id=contact-form-id data-parsley-validate>

        $.post("send-contact.php", $(this).serialize());

        $( '#contact-form-id' ).parsley( 'destroy' );

PHP：

<?php

header('Content-type: application/json');

?>

使用Javascript：

$("form.contact-form").each(function(){
var form = $(this);
var button = form.find("button[type=submit]");
var buttonText = button.html();

button.click(function(e){
    e.preventDefault();

    var formTop = form.offset().top;
    var url = form.attr("action");
    var data = form.serialize();
    form.find("input, select, textarea, span").removeClass("error");
    form.find(".msg").remove();

    button.html("Sending...");

    $.post(url, data, function(response){
        var status = response.msgStatus;
        var msg = response.message;

        if(status == "ok") {
            form.prepend('<p class="msg success"><a class="hide" href="#">hide this</a>' + msg + '</p>');
            form.find("input, select, textarea").val("");
            var valField = form.find(".select .value");
            var selectField = valField.siblings("select");
            var selectedText = selectField.find("option").eq(0).html();
            valField.html(selectedText);

        } else if(status == "error") {
            if(response.errorFields.length) {
                var fields = response.errorFields;
                for (i = 0; i < fields.length; i++) {
                    form.find("#" + fields[i]).addClass("error");
                    form.find("select#" + fields[i]).parents(".select").addClass("error");
                }
                var errors = response.errors;
                var errorList = "<ul>";
                for (i = 0; i < errors.length; i++) {
                    errorList += "<li>" + errors[i] + "</li>";
                }
                errorList += "</ul>";
                form.prepend('<div class="msg error"><a class="hide" href="#">hide this</a><p>There were errors in your form:</p>' + errorList + '<p>Please make the necessary changes and re-submit your form</p></div>');

            } else form.prepend('<p class="msg error"><a class="hide" href="#">hide this</a>' + msg + '</p>');
        }
        $(".msg a.hide").click(function(e){
            e.preventDefault();
            $(this).parent().slideUp();
        });
        button.html(buttonText);
        window.scrollTo(0, formTop);
    }, 'json');
})
});

您是否尝试过使用jquery？例如，ajax而不是post。

这样的事情？

    button.click(function () {
        $.ajax({
            url: url,
            type: 'POST',
            data: form.serialize(),
            contentType: "application/json;charset=utf-8",
            success: function (data) {
                if (data.msgSTatus == "ok"){
                    alert(data.message);
                    // play with html here once you know the page stays.
                 }
            },
            error: function (data) {
                alert('Fail.');
            }
        });
    });

就html追加而言，我个人在页面上已经有一个空的id，只是将div的内容设置为你收到的数据，会使js看起来更干净.. < / p>

尝试在其他脚本之前包含jquery。此外，使用Firebug或内置浏览器JS调试工具来解决Javascript错误。

我设法解决了这个问题。下面列出的变更用于比较目的，不仅可以帮助他人，还可以解决这个问题。特别感谢@WhiteRuski指出我正确的方向。 PHP 和 HTML 保持不变。这是新的 Javascript：

$("form.contact-form").each(function(){
var form = $(this);
var button = form.find("button[type=submit]");
var buttonText = button.html();

button.click(function(e){
    e.preventDefault();

    var url = form.attr("action");
    var data = form.serialize();

    // button.html("Sending...");
    button.html('<i class="fa fa-cog fa-lg fa-spin"></i>' + ' Sending ... ');

    $.post(url, data, function(response){
        var status = response.msgStatus;
        var msg = response.message;

        if(status == "ok") {
            toastr.success('<p>' + msg + '</p>');
            var valField = form.find(".select .value");
            var selectField = valField.siblings("select");
            var selectedText = selectField.find("option").eq(0).html();
            valField.html(selectedText);
        } else if(status == "error") {
            if(response.errorFields.length) {
                var fields = response.errorFields;
                for (i = 0; i < fields.length; i++) {
                    form.find("#" + fields[i]).addClass("error");
                    form.find("select#" + fields[i]).parents(".select").addClass("error");
                }
                var errors = response.errors;
                var errorList = "<ul>";
                for (i = 0; i < errors.length; i++) {
                    errorList += "<li>" + errors[i] + "</li>";
                }
                errorList += "</ul>";
                // toastr.error('<p>There were errors in your form:</p>' + errorList + '<p>Please make the necessary changes and re-submit your form</p>');  This lists the specific errpr in the field
                toastr.error('<p>There were a few errors in your form. Please resubmit with corrections.</p>');

            } else toastr.error('<p>' + msg + '</p>');
        }
        button.html(buttonText);
    }, 'json');
})
});

php echo在新标签中保持打开，而不是在jquery通知toastr.js中打开
