我有以下表格。在所有字段完成之前,“继续”按钮将被禁用。我已经在jfiddle上尝试了这个并且表单按预期工作,但在实际的.html文件在线它不起作用。例如,即使字段已经完成,按钮仍然被禁用,任何想法?

将您的代码包装在document.ready中可能会有所帮助。
$(document).ready(function(){
$('#username, #password, #password1, #email, #email1, #title, #firstname, #surname').bind('keyup', function() {
if(allFilled()) $('#continue').removeAttr('disabled');
});
function allFilled() {
var filled = true;
$('body input').each(function() {
if($(this).val() == '') filled = false;
});
return filled;
}
});
如果是WordPress,请注意您不能将$用于jQuery。您必须使用jQuery(&#39;正文输入&#39;),或者将代码包装在以下内容中:
$(function(){
$(document).ready(function(){
$('#username, #password, #password1, #email, #email1, #title, #firstname, #surname').bind('keyup', function() {
if(allFilled()) $('#continue').removeAttr('disabled');
});
function allFilled() {
var filled = true;
$('body input').each(function() {
if($(this).val() == '') filled = false;
});
return filled;
}
});
})(jQuery);
您是否在控制台中看到任何错误?

将您的代码放在$(document).ready(function(){// here})函数中,如下所示
$(document).ready(function(){
$('#username, #password, #password1, #email, #email1, #title, #firstname, #surname').bind('keyup', function() {
if(allFilled())
$('#continue').removeAttr('disabled');
});
function allFilled() {
var filled = true;
$('body input').each(function() {
if($(this).val() == '') filled = false;
});
return filled;
}
});

我会尝试:
$('#continue').prop('disabled',!allFilled());
而不是
if(allFilled()) $('#continue').removeAttr('disabled');
用户可以填写所有字段,然后删除一个。
