jQuery Validate 多个文本域的问题

其实除了可以用js调整,也可以用php调整啊,根据$_GET['t']的值输出不同的rule.
特意去看了下jQuery Validate插件,发现可以这样这么做:

<form id="myform">
    <input name="someinput" id="someinput" type="text">
    <button>submit</button>
</form>
javascript:

$('#myform').validate({rules:{
    someinput:{
        <?php if ($_GET['t']==1) :?>
        required:true,
        minlength:3,
        maxlength:15,
        number:true
        <?php else :?>
        required:true,
        minlength:1,
        maxlength:5,
        number:true
        <?php endif;?>
    }
}});

或者这么做:

function getQueryVariable(variable) {
    var query = window.location.search.substring(1);
    var vars = query.split('&');
    for (var i = 0; i < vars.length; i++) {
        var pair = vars[i].split('=');
        if (decodeURIComponent(pair[0]) == variable) {
            return decodeURIComponent(pair[1]);
        }
    }
}
$(function(){
var t = getQueryVariable('t');
$.validator.addMethod("someinput", function(value) {
    if(t==1){
        return !(value===null || value.length < 2 || value.length > 20);
    }else if(t==2){
        return !(value===null || value.length < 5 || value.length > 12);
    }
    return false;
}, 'Please enter "someinput"!');

$('#myform').validate({rules:{
    someinput:'someinput'
}});
});
