jQuery custom validation for a selected radio selection
- by Kaushik Gopal
Hey peeps,
This is my requirement: I have a bunch of radio box selections (types of workflows). If one of the radios are selected(i.e one particular type of workflow selected), I want to run a custom validation on that. This is what i tried, but it's not behaving well. Any help?
jQuery part:
$(document).ready(function() {
// this part is to expand the child radio selection if particular parent workflow selected
$("#concernedDirectorChoice").hide();
$("input[name^=workflowChoice]").change( function (){
if($(this).attr("class")=='chooseDir'){
$("#concernedDirectorChoice").show();
}else{
$("#concernedDirectorChoice").hide(); }
});
// FORM VALIDATION
$.validator.addMethod("dirRequired", function(value, element) {
return this.optional(element) || ($("input[name^=rdDir:checked]").length);
}, "That particular workflow requires a Director to be chosen. Please select Director");
$("#contExpInitiateForm").validate({
debug:true
,rules:{
RenewalNo: {required: true, number: true},
chooseDir: {dirRequired: true},
workflowChoice: {required: true} }
,errorPlacement: function(error, element) {
$('.errorMessageBox').text(error.html()); }
});
});
HTML form part:
<!-- Pick type of workflow -->
<table class="hr-table" >
<tr> <td class="hr-table-label " colspan=2 >Pick Workflow Type</td> </tr>
<tr>
<td> <input type="radio" name="workflowChoice" value="1"> </input> </td>
<td> Workflow 1 </td>
</tr>
<tr>
<td> <input type="radio" name="workflowChoice" value="2" class="chooseDir"> </input> </td>
<td> Workflow 2 (Dir selection required) </td>
</tr>
<tr>
<td> <input type="radio" name="workflowChoice" value="3"> </input> </td>
<td> Workflow 3 </td>
</tr>
</table>
<!-- Pick Director for Workflow type 2 -->
<table id="concernedDirectorChoice" name="concernedDirectorChoice" >
<tr><td class="hr-table-label" colspan=2 > Choose Concerned Director</td></tr>
<tr>
<td><input type="radio" value='Dir1' name="rdDir" /></td>
<td>Director 1</td>
</tr>
<tr>
<td><input type="radio" value='Dir2' name="rdDir" /></td>
<td>Director 2</td>
</tr>
<tr>
<td><input type="radio" value='Dir3' name="rdDir" /></td>
<td>Director 3</td>
</tr>
</table>
