使用jquery验证插件验证数组输入

Question

我有以下表格.我试图使用jquery验证插件验证输入.我尝试了一些代码,但它不起作用.当我点击提交按钮时,它就会转到表单的动作.

<form name="voucherform" action="something" method="post">
  <input type="text" name="reg_number[]" value="" />
  <input type="text" name="reg_number[]" value="" />
  <input type="text" name="reg_number[]" value="" />
  <input type="submit" name="submit" value="submit" />

你能告诉我如何使用jquery验证插件验证上面的表单吗？

谢谢 :)

我的Jquery代码:

 <script type="text/javascript" src="<?php echo base_url();?>support/datepicker/js/jquery-1.7.2.min.js"></script>
 <script type="text/javascript" src="<?php echo base_url();?>support/js/jquery.validate.js"></script>

 <script>
  $(document).ready(function() {

// validate signup form on keyup and submit
var validator = $("#voucherform").validate({
    showErrors: function(errorMap, errorList) {
        $(".errormsg").html($.map(errorList, function (el) {
            return el.message;
        }).join(", "));
    },
    wrapper: "span",
    rules: {

        reg_number[]: {
            required: true,
            minlength: 2,
            remote: {
                url: '<?php echo base_url();?>sales/invoice_check', async: false,
                type: 'post'
            },

        }
    },
    messages: {

        reg_number[]: {
            required: "Enter Reg Number",
            minlength: jQuery.format("Enter at least {0} characters"),
            remote: jQuery.format("{0} is already in use")
        },
    }
    });
    });
   </script>

你有两个问题:

1. 您没有form正确选择元素.

   您正在寻找form带有id"凭证"的标签,而您的标记不包含一个.您可能希望将选择器更改为:

   $("form[name='voucherform']").validate({ ... });
   

2. Brackets([])在JavaScript标识符中无效.这意味着您的脚本未正确解析.要解决此问题,只需将带括号的字段用引号括起来,即'reg_number[]'代替reg_number[].

调整验证码:

var validator = $("form[name='voucherform']").validate({
    showErrors: function(errorMap, errorList) {
        $(".errormsg").html($.map(errorList, function(el) {
            return el.message;
        }).join(", "));
    },
    wrapper: "span",
    rules: {
        'reg_number[]': {
            required: true,
            minlength: 2,
            remote: {
                url: '<?php echo base_url();?>sales/invoice_check',
                async: false,
                type: 'post'
            }

        }
    },
    messages: {
        'reg_number[]': {
            required: "Enter Reg Number",
            minlength: jQuery.format("Enter at least {0} characters"),
            remote: jQuery.format("{0} is already in use")
        }
    }
});

你可以在这里找到一个好的答案:jquery-validation-for-array-of-input-elements.在jquery.validate.js中,我们可以找到一个名为checkForm的函数,我们必须修改它如下:

checkForm: function() {
  this.prepareForm();
  for ( var i = 0, elements = (this.currentElements = this.elements()); elements[i]; i++ ) {
   if (this.findByName( elements[i].name ).length != undefined && this.findByName( elements[i].name ).length > 1) {
     for (var cnt = 0; cnt < this.findByName( elements[i].name ).length; cnt++) {
       this.check( this.findByName( elements[i].name )[cnt] );
     }
    } else {
     this.check( elements[i] );
    }
   }
  return this.valid();
}
