我的表单中有两个字段，我希望其中一个字段被填充。我找到了JQuery validate插件，但require_from_group似乎无效。
检查中的控制台返回：
Uncaught TypeError: validator.elementValue is not a function
我做的第一件事就是将类附加到所需的字段grouprequired。
现在我有JS文件;在我添加了short_description和language_from验证后，text_to_translate和file验证工作正常。
你知道问题出在哪里吗？
$(function () {
jQuery.validator.setDefaults({
debug: true,
success: "valid"
});
$("#job_creation_form").validate({
rules: {
short_description: {
required: true
},
language_from: {
required: true
},
text_to_translate: {
require_from_group: [1, '.grouprequired']
},
file: {
require_from_group: [1, '.grouprequired']
}
},
messages: {
short_description: {
required: "Short description can't be empty. Please fill this field."
},
language_from: {
required: "Please choose current language."
},
text_to_translate: {
require_from_group: "Either fill this form with a text or attach a file (below)."
},
file: {
require_from_group: "Either attach a file or fill text to translate (above)."
}
}
});
$.validator.addMethod("require_from_group", function (value, element, options) {
alert('kosd')
var $fields = $(options[1], element.form),
$fieldsFirst = $fields.eq(0),
validator = $fieldsFirst.data("valid_req_grp") ? $fieldsFirst.data("valid_req_grp") : $.extend({}, this),
isValid = $fields.filter(function () {
return validator.elementValue(this);
}).length >= options[0];
// Store the cloned validator for future validation
$fieldsFirst.data("valid_req_grp", validator);
// If element isn't being validated, run each require_from_group field's validation rules
if (!$(element).data("being_validated")) {
$fields.data("being_validated", true);
$fields.each(function () {
validator.element(this);
});
$fields.data("being_validated", false);
}
return isValid;
}, $.validator.format("Please fill at least {0} of these fields."));
});
在控制台的红线之前，有这样的：
jquery.validate.min.js:29 exception occured when checking element id_text_to_translate, check the 'require_from_group' method TypeError: validator.elementValue is not a function(…)
编辑：这是表单的实际HTML：

答案 0 :(得分：1)
根据OP's comment：
<script src="ajax.aspnetcdn.com/ajax/jquery.validate/1.9/…
因此，您正在使用jQuery Validate插件的1.9版，以及从插件的require_from_group文件的1.15版本中复制的additional-methods.js方法。自版本1.9起，require_from_group中的许多错误已得到修复，additional-methods.js中的方法版本需要与jQuery Validate版本匹配。
将jQuery Validate插件升级到版本1.15
src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.15.0/jquery.validate.js"
否则，它在这里工作：http://jsfiddle.net/s40kwon6/
