jQWidgets jqxValidator validationError事件
jQWidgets 用于在JavaScript的帮助下验证HTML表单。它有一些内置的规则,根据用户输入的验证要求,电子邮件、SSN、ZIP、最大值、最小值、间隔等。这里的自定义规则也可以根据具体要求来编写。
当表单验证时出现一些错误,就会触发validationError事件。
语法:
$('#jqxValidator').on('validationError', function (event) {
// Code section
});
Linked Files: 从给定的链接中下载jQWidgets。在HTML文件中,找到下载文件夹中的脚本文件。
