阻止默认值后重新启用提交 [英] Re-enabling Submit after prevent default

问题描述

我正试图解除绑定或重新启用默认的阻止默认设置，以便我的表单能够根据良好的数据进行提交.

I am trying to unbind or reenable the prevent default so my form will submit on good data.

我尝试了多个示例.这是我的代码和我尝试过的一些示例.

I have tried multiple examples. Here is my code and some of the examples i tried.

此代码非常适合我想要的.只是最后一件事，并重置获得此权限后可以实现的div.

This code works great for what i want to. Just the last thing and resetting the div which i can implement after i get this.

function lengthRestriction(elem, min, max) {
    var uInput = elem.value;
    if (uInput.length >= min && uInput.length <= max) {
        return true;
    } else {
        var cnt = document.getElementById('field');
        cnt.innerHTML = "Please enter between " + min + " and " + max + " characters";
        elem.focus();
        $('#ShoutTweet').submit(function(e) {
            e.preventDefault();

            //bind('#ShoutTweet').submit();
            //$('#ShoutTweet').trigger('submit'); 
        });
    }
}​

我也设置了jsbin http://jsbin.com/ebedab/93

i have a jsbin set up too http://jsbin.com/ebedab/93

推荐答案

我不确定您要问什么，但是如果您的目标是销毁自定义的submit处理程序，请使用此方法:

I'm not completely sure what you are asking, but if your goal is to destroy your custom submit handler, then use this:

$("#ShoutTweet").unbind("submit");

这假设您具有普通(非Ajax)格式.

This assumes that you have a normal (not Ajax) form.
