Jquery validator vs. bidimensional arrays
I'll just start with the example of my problem:
<form>
<input name="course[0][name]" />
<input name="course[0][type]" />
<input name="course[1][name]" />
<input name="course[1][type]" /&g开发者_如何学运维t;
...
...
</form>
obs: this is, of course, simplified.
So...how can i validate those since i can't predict the name? Is there a way to use regular expressions or something? utopic example:
rules: {
/course\[([0-9]+)\]\[name\]/: {
required: true
}
}
I couldn't find the solution in the documentation since its a bit confusing. thank you (:
As an alternative you can do something like this
$.validator.addClassRules({
inputName: {
required: true,
minLength: 5
},
inputType: {
required: true,
remote: "remoteurl"
}
});
<input name="course[0][name]" class="inputName"/>
<input name="course[0][type]" class="inputType"/>
So, I did a little bit of searching, and it looks like the keys in the rules object are simple jQuery selectors. According to this question, there is a regex filter which can be used. Between the two, your regex above should work.
Original idea:
... you don't need to predict them, your server already knows them. Just output that number into a script tag and then loop. Heck, you can even have the server loop for you.
If that is not an option, then you can use jQuery:
var rules = {
// simple rule, converted to {required:true}
name: "required",
// compound rule
email: {
required: true,
email: true
}
// whatever
}
// obviously, for just required, there are easier ways
var checkRules = {required:true};
$('#form-id input').each(function(i, elem)
{
/check\[\d\]\[(name|type)\]/.test(elem.name)
rules[elem.name] = checkRules
});
More a workaround: By default, you can specify a class named required on the fields that are required.
Another option would be to fill up the rules options programmatically (complete code in this gist):
Assuming a simple example HTML with the following body:
<body>
<form id="example">
<input name="course[0][name]" />
<input name="course[0][type]" />
<input name="course[1][name]" />
<input name="course[1][type]" />
<input type="submit" name="some_name" value="Go" id="some_name">
</form>
</body>
The corresponding javascript to determine matching elements via filter:
$(document).ready(function(){
var options = { rules : {} }
// put your regex in here ...
var courses = $('input').filter(function(){
return this.name.match(/course\[([0-9]+)\]\[name\]/);
});
for (var i = courses.length - 1; i >= 0; i--){
options["rules"][courses[i].name] = { required : true };
};
$("#example").validate(options);
});
