删除属性以使用 JavaScript 进行验证

【中文标题】删除属性以使用 JavaScript 进行验证【英文标题】:Delete attributes for validation with javaScript 【发布时间】:2019-05-12 05:03:58 【问题描述】:我正在创建一个函数来在输入的邮政编码上添加regex
。
我只为某些国家添加他的正则表达式,例如法国。
当我通过选择选择国家时,我已经完成的功能将其回调, 这在我将属性添加到输入时有效, 相反,它不起作用, 如果以后我想更改国家,请选择一个我不能检查邮政编码的国家。
浏览器继续进行验证以向我返回错误 验证“Le champ doit contenir 5 chiffres”。
如何修改 javascript 以取消添加的属性?
谢谢
function CodePostalRegEx(input, action)
if (action == "add")
$(input).attr('data-val', 'true'); // turn on validation
$(input).attr('data-val-regex', 'Le champ doit contenir 5 chiffres'); // message to show when validation fails
$(input).attr('data-val-regex-pattern', "^(([0-8][0-9])|(9[0-5]))[0-9]3$"); //regex
else
$(input).attr('data-val', 'false');
$(input).removeAttr('data-val-regex'); // message to show when validation fails
$(input).removeAttr('data-val-regex-pattern'); //regex
$(input).removeData('unobtrusiveValidation');
$(input).removeData('validator');

【问题讨论】:
发布你的html @ewwink 我已经添加了我的表单 html 的一部分 函数CodePostalRegEx()
是怎么调用的?请在您的问题中也添加它
【参考方案1】:
你有一些带有类的选择器,然后是 id。您只需要 id 因为它必须是唯一的并且它是最快的选择器。我还修改为使用所选元素的缓存,从而使代码更简单,并且不会使用选择器(不遍历)来访问 DOM 我通过添加的空缺失函数避免了错误。 setupAC
我还添加了这一行:jqinput.data('valRegexPattern', reg);
请注意按照标准删除了破折号和驼峰式大小写。
这段代码看起来很奇怪,你的意思是处理表单还是表单中的输入?无论哪种方式,这似乎都是错误的:
$("#MonProfilForm").each(function()
$.data($(this)[0], 'validator', false);
);
因此,鉴于您需要以下其中一项:
形式:
$("#MonProfilForm").data('validator', false);
输入
$("#MonProfilForm").find('input').each(function()
$.data($(this)[0], 'validator', false);
);
function CodePostalRegEx(jqinput, action)
var reg = "^(([0-8][0-9])|(9[0-5]))[0-9]3$";
if (action == "add")
jqinput.attr('data-val', 'true'); // turn on validation
jqinput.attr('data-val-regex', 'Le champ doit contenir 5 chiffres'); // message to show when validation fails
jqinput.attr('data-val-regex-pattern', reg); //regex
jqinput.data('valRegexPattern', reg);
else
jqinput.attr('data-val', 'false');
jqinput.removeAttr('data-val-regex'); // message to show when validation fails
jqinput.removeAttr('data-val-regex-pattern'); //regex
jqinput.removeData('unobtrusiveValidation');
jqinput.removeData('validator');
$("#MonProfilForm").each(function()
$.data($(this)[0], 'validator', false);
);
$.validator.unobtrusive.parse("#MonProfilForm");
function setupAC()
$("#PaysNaissance").change(function()
var cpn = $("#CodePostalNaissance");
var cn = $("#CommuneNaissance");
if ($(this).val().toLowerCase() != "france")
CodePostalRegEx(cpn, "remove");
cpn.unmask("data-mask");
if (cn.hasClass('ui-autocomplete-input'))
cn.autocomplete("destroy");
cn.removeData('autocomplete');
if (cpn.hasClass('ui-autocomplete-input'))
cpn.autocomplete("destroy");
cpn.removeData('autocomplete');
else
cpn.mask("00000");
CodePostalRegEx(cpn, "add");
setupAC();
);
