我正在尝试使用validationEngine插件制作自定义错误消息
默认使用以下内容时：
<input value="" class="validate[required]" type="text" name="name" id="name"/>
你没有在里面输入任何东西，你会收到消息：“*字段必需”，这很好，但我想要一些类似：“*名称要求”......
我的.js文件只有这个：
$("#Form_Name").validationEngine();
任何帮助将不胜感激，我已经有几天试图完成这个......

你需要做的就是修改jquery.validationEngine-en.js中的消息（或者你想要的任何语言，如果不是英语的话）。请记住，您更改的验证类型的所有字段都将显示相同的消息。
这也是您可以添加自己的自定义验证和消息的地方。
\编辑 - 啊，我明白你的意思了。好吧，我不能相信这一点，但是一家名为iPragmaTech的公司使用该字段的title属性提出了针对同一问题的解决方案。
它们覆盖了来自validationengine的buildprompt函数，并添加了选择自定义错误消息的功能。
以下是他们的代码：
var buildPrompt = $.validationEngine.buildPrompt;
$.validationEngine.buildPrompt = function(caller, promptText, type, ajaxed) {
// Get the rules to map the message for a method
var rulesRegExp = /\[(.*)\]/;
var getRules = rulesRegExp.exec($(caller).attr('class'));
var str = getRules[1];
var pattern = /\[|,|\]/;
var rules = str.split(pattern);
//Check if title attribute present in the element
//otherwise we shall use default error message
if ($(caller).attr('title')) {
var getMessages = rulesRegExp.exec($(caller).attr('title'));
var str = getMessages[1];
var pattern = /\[|,|\]/;
var messages = str.split(pattern);
var j = 0;
newPrompt = "";
for ( var i = 0; i < rules.length; i++) {
rules = $.validationEngine.settings.allrules[rules[i]]
if (rules) {
if (promptText.indexOf(rules.alertText) != -1) {
newPrompt += "
<p class="errorMsg">" + messages[j] + "
";
}
j++;
}
}
promptText = newPrompt;
}
buildPrompt(caller, promptText, type, ajaxed);
}
</p>
他们在'title'属性中添加了错误消息，这样可以灵活地为不同的字段自定义错误消息。以下是可以添加自定义错误消息的示例：
<input value="" class="validate[required,custom[noSpecialCaracters],length[0,20]]" name="user" id="user" title="[* Desired username is required,* No special caracters allowed for Desired username,* Desired username should have characters between 0 and 20]" type="text">
我希望这能解决你的问题。

jQuery('#fieldId').validationEngine('showPrompt', 'This a custom msg', 'error', true)
- 错误：提示样式，红色

您可以设置自己的自定义错误消息。在此脚本中，“required”已经在运行，现在我们将创建一个新规则“required_2”。 步骤1：在jquery.validationEngine.js文件中创建一个新案例 喜欢
case "required_2":
required = true;
errorMsg = methods._required(field, rules, i, options);
break;
为required_2添加添加功能
_required_2: function(field, rules, i, options) {
switch (field.prop("type")) {
case "text":
case "password":
case "textarea":
case "file":
default:
if (!($.trim(field.val())))
return options.allrules[rules[i]].alertText;
break;
case "radio":
case "checkbox":
var form = field.closest("form");
var name = field.attr("name");
if (form.find("input[name='" + name + "']:checked").size() == 0) {
if (form.find("input[name='" + name + "']").size() == 1)
return options.allrules[rules[i]].alertTextCheckboxe;
else
return options.allrules[rules[i]].alertTextCheckboxMultiple;
}
break;
// required for <select>
case "select-one":
// added by paul@kinetek.net for select boxes, Thank you
if (!field.val())
return options.allrules[rules[i]].alertText;
break;
case "select-multiple":
// added by paul@kinetek.net for select boxes, Thank you
if (!field.find("option:selected").val())
return options.allrules[rules[i]].alertText;
}
}
步骤：2 现在，您可以更改语言文件“jquery.validationEngine-en.js”以获取英语
"required_2": { // Add your regex rules here, you can take telephone as an example
"regex": "none",
"alertText": "* This field is required by mohan",
"alertTextCheckboxMultiple": "* Please select an option",
"alertTextCheckboxe": "* This checkbox is required",
"alertTextDateRange": "* Both date range fields are required"
},
步骤：3现在差不多完成了，你可以在你的html字段中使用它，例如
<input value="" class="validate[required_2] text-input" type="text" name="req1" id="req1" data-prompt-position="topRight:-70" />

**试试这个..对我有用:)如果使用jquery.validationEngine.js中的以下代码设置标题，修改了promtText
if（field.attr（“title”）！= null） promptText = field.attr（“title”）;
。**

这很有效
<input type="text" value="" class="input full-width validate[required,custom[integer]" data-errormessage-custom-error="your message when wrong syntax" data-errormessage-value-missing="your meesage when field empty" />
