jQuery validation - Change min max number checking at runtime
提问by Dzung Nguyen
Can I change the min, max of a number's validation at runtime ?
我可以在运行时更改数字验证的最小值、最大值吗？
I use jQuery validation plugin.
我使用jQuery 验证插件。
My simplified layout and structure to demonstrate how it should work. when I change the value of max range the max range's validation of the field number has to be changed too.
我的简化布局和结构来演示它应该如何工作。当我更改最大范围的值时，字段编号的最大范围验证也必须更改。

You can do this by specifying minand maxoptions in your validation rules:
您可以通过在验证规则中指定min和max选项来做到这一点：
For ex:
例如：
$("#myform").validate({
rules: {
field: {
required: true,
min: 13
}
}
});

Using this answerfrom another SO post as a guide I was able to change your code and get this to work.
使用另一个 SO 帖子中的这个答案作为指导，我能够更改您的代码并使其正常工作。
// Bind initial rule;
bindRangeRule(1, 2);
$("input[name='change-range']").on("keyup", function() {
var value = $(this).val();
// add some validation here off course to ensure only numbers are accepted.
// You can do that by checking the event.keyCode values I believe.
// If an invalid value was specified you can throw an alert
// or simply clear the input field and return false. Or similar.
// re-bind range rule
bindRangeRule(1, parseInt(value));
});
function bindRangeRule(from, to) {
var settings = $('form').validate().settings;
delete settings.rules.number;
settings.rules.number = {
required: true,
range: [from, to]
}
};
