然而,我有很长的形式,被分割成izar。 为了防止用户打碎浏览器后 but子并丢失数据,我有以下内容:

window.onbeforeunload = function() { return "Hitting back will cause you to lose all form data."; };

How would I insert a flag and apply to the last step so the form can be submitted properly? Thanks,

最佳回答

你们可以在最后一步上设定一个变数,以纠正和制止:

var okToSubmit = false;
window.onbeforeunload = function() { 
  if(!okToSubmit) return "Hitting back will cause you to lose all form data."; 
};
//set okToSubmit = true; on the last step

如果没有你目前的代码,我可以确切地说,在什么地方插入这个字,但是,在你的文字上移到最后一步时,就添加一个<代码>ok ToSubmit=真实;。
