自定义表单验证-Magento

我正在尝试使用jQuery在Magento中实现一些自定义表单验证，但是我不确定我是否具有正确的方法。

基本上，我需要验证以下内容：

1. 仅数字字段需要具有.00才能验证1到1.00

2. 字母必须大写

3. 号码不能大于9.99

4. 字段中没有空格

我正在考虑使用jQuery，并着手编写一些东西来验证表单：

<script>
    jQuery(document).ready(function() {
        jQuery.validator.addMethod("integer", function(value, element) {
            return this.optional(element) || /^-?\d+$/.test(value);
        }, "A positive or negative non-decimal number please");

        function(field, length) {
            if (!numericRegex.test(length)) {
                return false;
            }
            return (field.value.length <= parseInt(length, 4));
        },
    }
</script>

问题是我找不到其他验证字段的功能，请提供一些帮助。

很好的问题！

您不需要jQuery。您可以使用内置的Magento表单验证器执行此操作。首先，必须将用于设置表单以进行验证的javascript放在表单模板中：

<script type="text/javascript">
  var myForm= new VarienForm('[your form id]', true);
</script>

现在，通过添加适当的CSS类来准备表单字段。

号码不能大于9.99

<input type="text" class="required-entry validate-digits-range digits-range-0-9.99"/>

字段中没有空格

<input type="text" class="required-entry validate-alphanum"/>

而已！对于更具体的用例，您必须添加自定义验证规则：

仅数字字段需要具有.00才能验证1到1.00

Validation.add('validate-float','Input must be in the form of 0.00',function(v){
    return Validation.get('IsEmpty').test(v) || (!/\./.test(v));
});

然后通过以下验证：

<input type="text" class="required-entry validate-float"/>

字母必须大写

这是相似的，正则表达式必须测试一定范围的大写：

Validation.add('validate-uppercase','Input must be in uppercase',function(v){
    return Validation.get('IsEmpty').test(v) || (!/^[A-Z]+$/.test(v));
});

和使用像：

<input type="text" class="required-entry validate-uppercase"/>
