Question

我遇到了类似的问题。不应该“错误”是一个错误字符串？当我发出错误警告时，它是一个对象（[object Object]。当我取出“errorPlacement”块时，它工作正常。我尝试将errorPlacement块放在最后。当我像这样更改第6行时： element.closest（“div”）。append（“test message”）; 我在表单中获取“测试消息”字符串，没有错误。所以问题是“错误”是一个对象而不是一个字符串。这是插件的问题吗？我正在使用jQuery验证插件1.7和jquery 1.6ish

$("#student-set-form").validate({
        errorPlacement: function(error, element) {                
            console.log(error);
            alert(error);
            element.closest("div").append(error);
        },

引用OP：

“不应该”错误“是一个错误字符串？当我警告错误时它是一个错误字符串 object（[object Object]。“

不，它不应该是一个字符串。这确实是一个看起来像这样的对象......

<label for="myfield" class="error">This field is required</label>

如果要从error对象中提取字符串，请使用jQuery .text() method。

这将为您提供包含错误消息的字符串：

error.text()

否则，您不清楚您的代码遇到了什么问题。

当需要字符串时，JQuery验证插件errorPlacement会传入错误对象
