如何验证复选框，以便他们需要为每个问题选择至少一个？

这是我的表格... http：//test9.favstay.com/form.php

Answer 1

使用最小和最大长度

<input type="checkbox" value="palin" name="upd" id="upd"/>
</p>
<p>
<label for="fox">Fox</label>
<input type="checkbox" value="fox" name="upd" id="upd" />
</p>
<p>
<label for="left">Left</label>
<input type="checkbox" value="left" name="upd" id="upd" />
</p>

验证

$("#upd").rules("add", {
        required: true,
        minlength: 1,
        maxlength: 1,
    messages: {
        required: "Please pick a category",
        minlength: jQuery.format("Please, Check at least one box"),
        maxlength: jQuery.format("Please, You checked too many boxes"),
    }
});

为每个复选框添加ID（q4，q5等），将q3，q4等替换为#upd。只需根据您的需求进行调整。

您可以使用jquery验证插件来验证HTML表单，并验证复选框，您可以在验证选项中添加“自定义选择器”。查看示例here
