Jquery Impromptu回调问题 – $ .prompt失败
我有一个jQuery Impromptu的问题，特别是带有内联表单回调函数的$ .prompt。
现在，实际的具体问题如下。 如果email_address字段在提交时为空，我无法获得$.prompt('Please supply an email address for the customer') ，但是如果我将其更改为alert('Please supply an email address for the customer')它将工作。
我猜这是一个范围问题，因为其他$.prompt调用按预期工作，我假设是因为它们在$.post回调函数内。
我一直在努力寻找大量的回调表单function文档，尽管我觉得我理解e ， v和f变量，但m （Message）并不是我以前用过的东西。 当我将m登录到控制台日志时，它看起来像jQuery Impromptu对象，但是我不确定如何访问它的属性。 我尝试过m.prompt()和$.m.prompt()但这些只是猜测我将如何访问prompt函数。
使用Javascript
var txt = ''; function mycallbackform(e,v,m,f) { if(v != undefined) { if (v == true) { console.log(f); if (f.email_address.length == 0) { console.log(m); $.prompt('Please supply an email address for the customer'); } else { $.post('". $this->view->url(array(), 'admin-create-user-from-checkout') ."', f, function(data) { if(data.status) { $.prompt('Customer Record Created Successfully'); } else { $.prompt('Customer Record could not be created'); $('#email_address').val($('#old_email_address').val()); } }, 'json'); } } else { $('#email_address').val($('#old_email_address').val()); } } $.prompt(txt,{callback: mycallbackform, buttons: { Ok: true, Cancel: false }});
控制台日志为m

问题解决了！

使用新的事件系统，回调绑定到提示符。 因此必须在销毁提示之前调用回调。 即兴不一次用于多个提示。
如果你想解决这个问题，一个简单的解决方案就是setTimeout（10，function（）{$ .prompt（…）;}）; 回调内部。 这将为之前提示关闭提供机会。
修正了Javascript
var txt = ''; function mycallbackform(e,v,m,f) { if(v != undefined) { if (v == true) { if (f.email_address.length == 0) { setTimeout(function(){ $.prompt('Please supply an email address for the customer'); }, 10); } else { $.post('". $this->view->url(array(), 'admin-create-user-from-checkout') ."', f, function(data) { if(data.status) { $.prompt('Customer Record Created Successfully'); } else { $.prompt('Customer Record could not be created'); $('#email_address').val($('#old_email_address').val()); } }, 'json'); } } else { $('#email_address').val($('#old_email_address').val()); } } $.prompt(txt,{callback: mycallbackform, buttons: { Ok: true, Cancel: false }});
