禁用提交按钮，直到对表单元素进行任何更改?

问题描述

这里是我正在尝试做的事情.提交表单后，我要禁用提交"按钮，直到更改任何表单元素.我已经在stackoverflow上使用了一个不同的问题，几乎可以正常工作了:

Heres what im trying to do. After the form is submitted, i want to disable the submit button until any form element is changed. I already got it almost working using a different question on stackoverflow:

$('#myform').find (':submit').attr ('disabled', 'disabled');

// Re-enable submit
var form = $('#myform');
$(':input', form.get(0)).live ('change', function (e) {
    form.find (':submit').removeAttr ('disabled');
});

一个问题是，如果禁用了按钮，并且用户单击了该按钮，则表示更改并现已启用.因此，只需双击该按钮即可重新提交！有什么建议吗?

One problem is that the if the button is disabled, and the user clicks the button, that counds as a change and its now enabled. So a simple double click of the button re-submits! Any suggestions?

推荐答案

[type!="submit"]

$(':input[type!="submit"]', form.get(0)).live ('change', function (e) {
    form.find (':submit').removeAttr ('disabled');
});
