用jQuery驗證幾個輸入的最小集合值

Question

我有多個具有相同名稱的文本輸入，並且如果所有輸入的總值小於1，我試圖阻止表單提交。例如，用戶不能將所有輸入都設為0，但至少在其中之一上放1，這樣所有投入的總價值至少為1。

我在jquery validate中創建了一個方法來檢查值是否大於所選輸入的0

<td><input class='{nbTeams: true} nbTeamsVal' type="text" class="form-control" id="nbTeamsMiniSoccer_20" name="nbTeams[]"></td>
<td><input class='{nbTeams: true} nbTeamsVal' type="text" class="form-control" id="nbTeamsYouthMale_20" name="nbTeams[]"></td>

這是方法：

$.validator.addMethod("nbTeams", function(value, elem, param) {
  return $(".nbTeamsVal").value > 0;
  },"Collective value must be more than 1!"
);

這是我的規則和自定義消息

$(document).ready(function () {

  $('#myForm').validate({
      rules: {
          "nbTeams[]":{
            required: true
          }
      },
      messages: {
        "nbTeams[]":"This group of fields can only contain numbers and one must contain a value of at least 1."
      },
      errorElement : 'div',
      errorLabelContainer: '.errorTxt',
      submitHandler: function (form) { 
        form.submit();
      }
  });

});

我編輯您的代碼試試這個：

 $.validator.addMethod("nbTeams", function(value, elem) { var sumOfVals = 0; $(".nbTeamsVal").each(function () { sumOfVals = sumOfVals + parseInt($(this).val()); }); return sumOfVals>0; },"Collective value must be more than 1!" ); $('#myForm').validate({ rules: { "nbTeams[]":"nbTeams" }, errorElement : 'div', errorLabelContainer: '.errorTxt', submitHandler: function (form) { alert('valid form submitted'); // for demo return false; // for demo } });
