所以我有一个淘汰赛原型,你动态添加输入,然后设置他们自己的设置。将其视为表单构建者就是这样。但是,我注意到残疾人和被要求的人并没有那么好。它将值设置为disabled或required但是当我将其设置为false时,它仍然保留在元素上而没有其状态,导致它仍然起作用。请任何人帮助或给予指导。

<div class="leftpanel">
<div class="input-row" data-bind="foreach: inputItems">

$(function(){

this.label = ko.observable(label);

var ViewModel = function ViewModel() {

this.addInput = function addInput() {

ko.applyBindings(new ViewModel());

你最好使用Knockout自己的内置disable
绑定处理程序:
<input data-bind="disable: disabled, attr: { name: name, placeholder: placeholder, value: value, type: type }" />
请参阅Fiddle
或者,您可以查看明确的&#39;真实性&#39;在您的情况下,如果条件不满足,Knockout将删除该属性。例如:
<input data-bind="attr: { disabled: disabled() === 'true', ...}" />
请参阅此Fiddle(在&#39;禁用&#39;输入中键入&#39; true&#39;以激活disabled
)。
