问题描述
我在进行一些 jquery 验证的表单中遇到问题.如果未填写特定输入字段，则应通过添加禁用属性来禁用前进"按钮:
I have a problem in a form where I do some jquery validations. If a specific input field is not filled out, it should disable a "step forward" button by adding a disabled attribute:
if errors
$('.btn-move-forward').attr("disabled", true)
这可行，但我在该按钮上也有一个点击事件:(咖啡稿)
that works but I also have a click event on that button: (coffeescript)
$('.btn-move-forward').click ->
$('#step2, #step3').toggle()
我希望 .btn-move-forward 在按钮被禁用时不会触发点击事件，但它确实会触发！！
I expect .btn-move-forward to not fire the click event when the button is disabled but it does!!
首先:我不明白为什么，因为每个浏览器规范都定义不应该发生这种情况.无论如何，我尝试通过执行以下操作来绕过它:
First: I don't understand why because every browser spec defines that this should not happen. Anyways, I tried to bypass it by doing the following stuff:
$('.btn-move-forward').click ->
if !$(this).is(:disabled)
$('#step2, #step3').toggle()
或者这个
$('.btn-move-forward').click ->
if $(this).prop("disabled", false)
$('#step2, #step3').toggle()
或者像这样组合事件监听器:
or combining the event listeners like this:
$('.btn-move-forward').on 'click', '.btn-move-forward:enabled', ->
$('#step2, #step3').toggle()
不，所有这些都无法正常工作.该按钮仍用作向前移动按钮.
No, all of this won't work properly. The button still behaves as a move-forward button.
我想要的只是按钮不监听 onclick 如果它被禁用.
All I want is the button not listening to onclick if it is disabled.
推荐答案
disabled 属性仅适用于表单元素.这意味着除非 .btn-move-forward 元素是 或 那么 disabled 属性将不起作用.
The disabled property only applies to form elements. This means that unless the .btn-move-forward element is a <button> or <input type="button"> then the disabled attribute will have no effect.
您可以在此处查看使用 按钮 的工作示例:
You can see a working example using a button here:
$('.btn-move-forward').prop("disabled", true).click(function() {
console.log('Moving forward...');
