How do I remove the 'required' rules from all form inputs in jQuery Validate?
提问by bcmcfc
As above, how can I remove all of the required rules from a form using jQuery Validate?
如上所述，如何使用 jQuery Validate 从表单中删除所有必需的规则？
This is what I have at present:
这是我目前所拥有的：
var settings = $('form').validate().settings;
//alert(settings.rules.toSource());
for (var i in settings.rules){
alert(i);
delete settings.rules.i;
// ^ not sure about how to do this properly,
// and how to just delete the 'required' rule and keep the rest intact
}
The function native to jQuery Validate returns an undefined error:
jQuery Validate 的原生函数返回一个未定义的错误：
$("input, select, textarea").rules('remove','required');

As can sometimes be the case, I appear to have stumbled on the answer just after resorting to posting on here.
有时可能是这种情况，我似乎在诉诸于此处发帖后偶然发现了答案。
for (var i in settings.rules){
delete settings.rules[i].required;
}
Works.
作品。

And if you don't want to mess with validate's internal settings, you can use the public function in this way:
如果你不想弄乱validate的内部设置，你可以这样使用public函数：
$('input, select, textarea').each(function() {
$(this).rules('remove', 'required');
});
Note that leaving out the second parameter (required) would remove all the rules, not just the "required".
请注意，省略第二个参数（必需）将删除所有规则，而不仅仅是“必需”。

When you need to remove a required input, you need also delete the attr of your input, test this.
当您需要删除必需的输入时，还需要删除输入的属性，测试一下。
$('element').rules('remove', 'required');
$('element').removeAttr('required');
$('element').rules('remove', 'required');
$('element').removeAttr('required');

You can disable jquery validate rules globally for client side validation using the ignore property (see validator options https://jqueryvalidation.org/validate/). This is useful for testing server side validation.
您可以使用 ignore 属性全局禁用客户端验证的 jquery 验证规则（请参阅验证器选项https://jqueryvalidation.org/validate/）。这对于测试服务器端验证很有用。
You can disable all rules
您可以禁用所有规则
$.validator.setDefaults({
ignore: ":hidden, input, select, textarea"
})
This is a jquery selector so you also do,
这是一个 jquery 选择器，所以你也这样做，
$.validator.setDefaults({
ignore: ":hidden, input[required], select[required], textarea[required]"
})
For additional inputs just add as needed.
对于其他输入，只需根据需要添加。
You can also remove html validation with something like this for dev environment (since its a slow selector):
您还可以使用类似这样的东西为开发环境删除 html 验证（因为它是一个缓慢的选择器）：
$("*[required]").removeAttr("required");
$("*[maxlength]").removeAttr("maxlength");
$("*[minlength]").removeAttr("minlength");
$("*[pattern]").removeAttr("pattern");
