我有一个带有表单的页面。我正在尝试将该表单发送到另一个页面以便使用AJAX进行处理。但是无论何时调用AJAX，我都会得到一个Uncaugh RangeError。
我通过Jquery CDN使用最新版本的jQuery，所有其他jQuery都在我的页面上工作，所以我知道我的代码必须存在问题。
这是错误

答案 0 :(得分：0)
您已经提交表单提交很久!!!您无法将e.preventDefault();置于Ajax success:回调中并期望它能够正常运行。那太晚了。
此外，您不应该使用按钮单击来捕获表单提交，因为按键也可以触发表单提交。始终使用form事件。
例如：下面我删除了大部分代码，以澄清一个使用sentinel变量控制表单是否允许正常提交的简单模式。
$(document).ready(function(){
var allowSubmit = false;
$('#ipcrStep1').on('submit', function(e){
if (!allowSubmit){
// FIND FORM DATA FIELDS
// AJAX SENDS THE FORM CODE TO THE PHP PROCESSING PAGE ACCORDING TO
$.ajax({
type : 'POST',
url : '/processipcr/step1.php',
dataType : 'json',
data: {...},
// ONCE THE FORM HAS BEEN PROCESSING AT THE PROCESSING PAGE THIS CODE ENABLES THE NEXT STEP
success: function(e){
// ALLOW NEXT SUBMIT TO WORK NORMALLY
allowSubmit = true;
// ALERT MESSAGE UPON SUCCESSFUL UPDATE TO DATABASE
// THIS CODE ENABLES THE NEXT SECTION OF THE PAGE (FORM???)
$(document).find('#form2').trigger('submit');
}
});
}
return allowSubmit;
});
});
其他选项包括将处理程序与on和off相关联，以便您可以启用一个表单并禁用之前的表单。
