jquery validate：自定义验证规则

发布于 2024-09-18 19:50:23 字数 2799 浏览 2 评论 0原文

我希望此表单仅在用户选择“Sí”作为选择问题的答案时才需要字段“Nombre”。此外，如果用户选择“Sí”，则应提供电子邮件或电话（teléfono）。

我正在使用验证插件，但尚未找到编写了类似规则的文档。我该如何编码？

查看文档，我想我需要编写 required( dependency-expression) 或 required(dependency-callback) 方法，但我不知道哪个或如何，因为当单击这些方法时，它们的文档似乎丢失=/

I want this form to make the field 'Nombre' required only if the user picks "Sí" as the answer to the select's question. Additionally, if the user selects "Sí", either an email or a phone (in teléfono) should be provided.

I'm using the validate plugin and haven't found a doc in which a similar rule has been coded. How can I code this?

Looking at the documentation, I think I need to code either a required(dependency-expression) or required(dependency-callback) method, but I don't which or how, since when clicking the methods their documentation appears missing =/

您需要创建自己的自定义规则，并将此类添加到您的两个字段中。

在 js 文件中：

jQuery.validator.addMethod("newRuleOr", function(value, element) {
        if($('#recomiendaONo').val() == 'Si'){
            return $('#emailRecomendado').val() != '' && $('#telefonoRecomendado').val();
        }
        return true;
   }, "Telefono o mail deben informarse."
);

在 html 代码中，您必须将新类添加到字段中。

<input class="texto newRuleOr" id="nombreRecomendado" name="nombreRecomendado" type="text" size="30"/>
...
<input  class="texto newRuleOr" id="emailRecomendado" name="emailRecomendado" type="text" size="30"/>

另一个提示，切勿使用表格来设计页面样式，而应使用 div、浮动和百分比。

you need to create your own custom rule, and add this class to your both fields.

In your js file:

jQuery.validator.addMethod("newRuleOr", function(value, element) {
        if($('#recomiendaONo').val() == 'Si'){
            return $('#emailRecomendado').val() != '' && $('#telefonoRecomendado').val();
        }
        return true;
   }, "Telefono o mail deben informarse."
);

And in your html code you have to add the new classes to the fields.

<input class="texto newRuleOr" id="nombreRecomendado" name="nombreRecomendado" type="text" size="30"/>
...
<input  class="texto newRuleOr" id="emailRecomendado" name="emailRecomendado" type="text" size="30"/>

Another tip, never use table to styling your page, use divs, floats, and percentage.

您可以查看他们的演示页面并查看硬编码示例如何使其工作。如果未选择选择，则仅使用 javascript 禁用字段，并且当选择选择时，禁用的属性将被删除。

从演示站点复制粘贴：

//code to hide topic selection, disable for demo
var newsletter = $("#newsletter");
// newsletter topics are optional, hide at first
var inital = newsletter.is(":checked");
var topics = $("#newsletter_topics")[inital ? "removeClass" : "addClass"]("gray");
var topicInputs = topics.find("input").attr("disabled", !inital);
// show when newsletter is checked
newsletter.click(function() {
    topics[this.checked ? "removeClass" : "addClass"]("gray");
    topicInputs.attr("disabled", !this.checked);
});

You can look at their demo page and see hardcoded example how to make this work. Fields are just disabled with javascript, if selection is not selected, and when selection is selected disabled attributes are removed.

Copy paste from demo site:

//code to hide topic selection, disable for demo
var newsletter = $("#newsletter");
// newsletter topics are optional, hide at first
var inital = newsletter.is(":checked");
var topics = $("#newsletter_topics")[inital ? "removeClass" : "addClass"]("gray");
var topicInputs = topics.find("input").attr("disabled", !inital);
// show when newsletter is checked
newsletter.click(function() {
    topics[this.checked ? "removeClass" : "addClass"]("gray");
    topicInputs.attr("disabled", !this.checked);
});
