Make Jquery validation plugin work on inputs with

2020-07-08 07:33发布

Well it took me long enough to find out that the JQuery form validation plugin only works on fields with a "name" attribute.

Anyway, I use it to make all the fields required.

My problem is that at some point, I have one text input

<div id='choices'>
  <input type='text' />
</div>
<a href='#' id='add-choice' >Add input </a>

the user can add as many text inputs as he wants :

$("#add-choice").live("click",function(){
                    $("#choices").append("<input type='text' /><br>");
});

And I want these new fields to be also required. Even if I give a name to the first input. What should I do for the new inputs added dynamically ?

Is there a way to use the plugin without using the name attr, or is there another solution ?

Give them a name, any name

Is there a way to use the plugin without using the name attr?

No

Is there another solution?

It depends on what you are doing with the fields - you clearly don't need a name on them for any other reason than to make jquery validate work, so why don't you just make up a name and call them all that?

correction - need unique names see comments

var i = 0;
$("#add-choice").live("click",function(){
 $("#choices").append("<input type='text' name='bob" + i + "' class='required'/><br>");
 i = i + 1;
});

Quote OP:

No, you cannot use the jQuery Validate plugin if you do not have name attributes on all of your fields.

As per documentation:

Markup recommendations

The name attribute is '''required''' for input elements, the validation plugin doesn't work without it.

The "workaround" is to have jQuery create a unique name when it creates the new input.

Yes you can do it, but with limitations

Limitation: You will not have flexibility to change messages while using different rules.

<form ="validationForm">
<input type="text" class="required" title="required message" />
</form>

jQuery("#validationForm").validate();
