极客教程jQWidgets jqxValidator规则属性
jQWidgets 用于在JavaScript的帮助下验证HTML表单。它有一些内置的规则，根据用户输入、电子邮件、SSN、ZIP、最大值、最小值、区间等验证的要求。也可以根据具体要求编写自定义规则。
rules属性用于为指定的jqxValidator设置规则。
语法:
{
input: 'selector-of-the-input',
message: 'Custom message on error',
action: 'Custom action (keyup, change...etc)',
rule: 'Build rule(ssn, phone, email...)
or custom function',
position: 'Position of the hint (format pos:x,y)',
hintRender: 'Function for hint rendering'
}
