我正在使用JQuery验证插件。我想为其中一个字段指定maxlength
。它可以指定如下。
rules: {
Message: {
required: false,
maxLength: 200
}
}
但是我没有在外部定义规则,而是想在html输入代码中指定规则
类似于:
<input type="text" name="AssistanPhone" value="" class="required" />
在上面的例子中,“required”是通过类指定的。类似地,我如何指定jquery插件可以识别的maxlength,并在长度超过时给出错误消息?
谢谢!

不是资本L
其l
例如:
$( "#myform" ).validate({
rules: {
field: {
required: true,
maxlength: 200
}
}
});

据我所知,您无法通过属性指定消息,但可以将maxlength
指定为属性
<input type="text" name="AssistanPhone" value="" required maxlength="3" />

我自己更新了验证器的javascript代码(所以我现在只使用我的1.8.1版而不是升级版),但这是我做的(第767行):
classRules: function(element) {
var rules = {};
var classes = $(element).attr('class');
classes && $.each(classes.split(' '), function() {
if (this in $.validator.classRuleSettings) {
$.extend(rules, $.validator.classRuleSettings[this]);
}
if (this.toLowerCase().lastIndexOf('maxlength-', 0) === 0) { // starts with
var x = parseInt(this.substring(10)); // take number after 'maxlength-'
$.extend(rules, {maxlength: x});
}
});
return rules;
},
我为&#34; maxlength - &#34;添加了额外的if-test,所以现在我可以添加类似&#34; maxlength-10&#34;限制为10.当然我也可以添加minlength等。
