jQuery Validate插件定制消息仅显示在输入数组的第一个输入上

上下文

我有一个多步骤表单，我正在尝试验证表单的每一步（所有输入字段均必填）

搜索并找到有效的解决方案以验证数组的多个输入后：

$("[name^=serialNbs]").each(function() {
  $(this).rules("add", {
    required: true,
    messages: {
     required: "Il faut remplir le numéro de série"
    }
  });
});

我仍然有与该消息有关的问题。

问题

我的个性化消息仅在第一个输入（第3步）上显示

Validate step 3

摘要

以下是代码段，只需在第一步上默认选择单选选项（ Computer＆Sonceboz ），在上给出1到10之间的数量第二步，然后尝试在不填写输入内容的情况下转到第三步 

$(document).ready(function() {
  var id, current_div;
  var valid = $("#add_to_stock").validate({
    rules: {
      pc_quantity: {
        required: true,
        range: [1, 10],
        digits: true
      },
      /*pc_model:{
          required: true
      },
      hard_type:{
          required: true
      },
      hard_model:{
          required: true
      },*/
      hard_quantity: {
        required: true,
        range: [1, 10],
        digits: true
      }
    },
    messages: {
      pc_quantity: "La quantité doit être entre 1 et 10",
      pc_model: "Il faut choisir un modèle",
      hard_type: "Il faut choisir un type",
      hard_model: "Il faut choisir un modèle",
      hard_quantity: "La quantité doit être entre 1 et 10"

    },

答案 0 :(得分：1)

您是否正在动态生成这些其他字段？它不能像您期望的那样工作，因为当您调用包含.each()方法的.rules()时，这些附加字段尚不存在。创建它们后，您必须在 后在这些新字段上调用.rules()。

它们仍然显示为required的原因是因为HTML元素中还具有required属性，这是多余的。如果您要使用jQuery Validate方法正确分配required规则，则不需要内联required属性。

似乎您也可以从if / else语句中提取一些多余的行，但这取决于您。

类似的东西：

if (quantity != 1) {

  for (i = 0; i < quantity - 1; i++) {

    if ($("#serialNb_" + y).length == 0) {
      console.log("1: i:" + i + " ; q:" + quantity + " ; y:" + y + " ; x:" + x);
      labelField = '<label for="serialNb_' + y + ' " class="col-sm-2 control-label padding-right">' + 'Numéro de série ' + y + ' :</label>';
      inputField = '<div class="col-sm-10"><input id="serialNb_' + y + '" name="serialNbs[' + y + ']" class="form-control " type="text" value="" /></div>'; 
    }

    // redundant lines on both sides of if/else??
    y++;
    $(wrapper).append(labelField, inputField);

    // assign the rules/messages right here, just after a new field is inserted
    $('#serialNb_' + y).rules("add", {
        required: true,
        messages: {
            required: "Il faut remplir le numéro de série"
        }
    });

  }  // end for loop

}  // end if

或者，如果一次创建所有其他字段，则可以在创建所有这些其他字段之后立即将原始.each()循环移动到一个点。

if (quantity != 1) {
    // create all fields
    ....
}

// all additional fields exist now
$("[name^=serialNbs]").each(function() {
    $(this).rules("add", {
        required: true,
        messages: {
            required: "Il faut remplir le numéro de série"
        }
    });
});
