javascript - How do I perform string splitting in a form before submission? -

i have form requires input data validated before submission. types of validation checks - can more 1 per input element - entered input element, , validation performed jquery.

my approach put types of validation required , separated commas - such "blank,email" - "checks" attribute of input element. jquery extract part, split array, , loop through each validation type.

the problem is, not want submit form until validation checks completed. when use "split" function, returns array, program takes boolean true returned , form submitted after first input element.

here's sample of form, taking note looks similar other fields:

<tr>    <td>full name</td>    <td><input type="text" name="accountname" check="blank"></td>  </tr>  <tr>    <td>nric</td>    <td><input type="text" name="accountnric" check="blank,nric" maxlength="9"></td>  </tr>

and here's jquery validation code:

// perform validation checks  $("form").submit(function()                   {    // loop through input fields    $("form input, form textarea, form select").each(function()                                                     {      // if none of input's parents hidden      if($(this).parents(":hidden").length == 0)      {        var thisvalue = $(this).val();        var checkwhat = $(this).attr("check");        var checkarray = checkwhat.split(",");        for(var i=0; i<checkarray.length; i++)        {          switch(checkarray[i])          {            case "blank": alert(checkblank(thisvalue)); break;            case "nric": alert(validatenric(thisvalue)); break;            case "email": alert(validateemail(thisvalue)); break;          }        }      }    });  });

i should clarify error checking variable hasn't been added in yet codes still being tested in parts.

any appreciated!
