通过单击按钮在字段有效时显示容器

Question

我是 jQuery 的新手。

我正在使用一个名为 jQuery Validate 的 jQuery 插件。我尝试查看他们网站上的示例，但找不到与我的相似的内容。

我尝试了各种方法，但我无法让它工作。

想法是在用户成功填写邮政编码并单击按钮时显示数据容器。当他们按下输入键盘按钮时，它不应该出现。

$("#searchForm").validate({
    rules: {
        text: {
            required: true,
            minlength: 7
        }
    }
});

$(".trigger").click(function(e) {
    $(".even").removeClass("hide");
});

html {
    overflow-x: hidden;
}

body {
    background-image: radial-gradient(51.26% 104.44%, #313B4B 0%, #222831 100%);
    padding: 35px 30px;
}

li {
    color: #92B572;
    list-style-type: none;
    font-size: 18px;
    margin: 10px 0;
}

h1,
h2,
h4,
span {
    color: #B9E4FA;
}

h3 {
    padding-top: 130px;
    color: #FFF;
}

h1 {
    font-size: 45px;
    font-weight: light;
    line-height: 55px;
    text-align: center;
}

h2 {
    font-size: 25px;
    line-height: 55px;
    margin: 0 0 50px 0;
    text-align: center;
}

Answer 1

每当用户键入或更改它的值时，您需要检查该字段是否 valid()（使用此插件的表单中的每个字段都有该方法）：

$("#searchForm input").on("keyup", function() {
  if ($(this).valid()) {
    $("#data-container").show();
  }
  else {
    $("#data-container").hide();
  }
});

您更新的代码段：

$("#searchForm").validate({
    rules: {
        text: {
            required: true,
            minlength: 7
        }
    }
});

$(".trigger").click(function(e) {
    $(".even").removeClass("hide");
});

$("#searchForm input").on("keyup", function() {
  if ($(this).valid()) {
    $("#data-container").show();
  }
  else {
    $("#data-container").hide();
  }
});
