Title: Validatebox validation on dynamically created from elements
Post by: sm_79 on July 06, 2014, 01:14:33 PM
Hi,
I am using jquery easyui validatebox for validating data in my form. However, in one of the forms, there is scope to create a group of form elements dynamically by clicking 'add elements' button.

Code:
                 <fieldset id="teacher_2">
                        <legend style="display: none">Teacher Details</legend>
                        <div id="tchentry1" class="clonedInputTch">
                            <h2 id="reference_tch" name="reference_tch" class="heading-reference">Detail #1</h2>
                            <div class="form-group">
                                <input type="text" name="tch_fname[]" class="form-control easyui-validatebox" placeholder="First name" data-options="required:true"/>
                            </div>
                            <div class="form-group">
                                <input type="text" name="tch_lname[]" class="form-control easyui-validatebox" placeholder="Last name" data-options="required:true"/>
                            </div>
                            <div class="form-group">
                                <input type="text" name="tch_email[]" class="form-control easyui-validatebox" placeholder="Email" data-options="required:true,validType:'email'"/>
                            </div>
                            <div class="form-group">
                                <input type="text" name="tch_userid[]" class="form-control easyui-validatebox" placeholder="User ID" data-options="required:true,validType:'minLength[5]'" />
                            </div>
                        </div>
                        <p class="text-center">
                            <button type="button" id="btnAddTch" name="btnAddTch" class="btn bg-olive">add teacher</button>
                            <button type="button" id="btnDelTch" name="btnDelTch" class="btn btn-danger">remove teacher above</button>
                        </p>
                    </fieldset>

On clicking the 'add teacher' button, basically I am using jquery .clone() method to create a copy of the div with class 'clonedInputTch'. As you can see, I have used "easyui-validatebox" class for validation of the form elements.

When there is only set of form elements, the validation is working fine. However, once a new set of fields have been generated dynamically, the validation is not working. And at this point getting following error in console:
Code:
Uncaught TypeError: Cannot read property 'options' of undefined jquery.easyui.min.js:5943
_43b jquery.easyui.min.js:5943
(anonymous function) jquery.easyui.min.js:5984
x.extend.each jquery.js:590
x.fn.x.each jquery.js:237
$.fn.validatebox.methods.enableValidation jquery.easyui.min.js:5983
$.fn.validatebox jquery.easyui.min.js:5955
(anonymous function) registerParent.php:200
x.event.dispatch jquery.js:4692
y.handle
Please let me know if this functionality is possible. If so, kindly guide on how to implement the same.
Thanks in advance.

Please call $.parser.parse function to parse the validatebox components after generating elements.
Code:
var ff = $('#tchentry1').clone().attr('id','').appendTo('#teacher_2');
$.parser.parse(ff);

Hmmm... and how can I do if have 2 forms and once the first is validated (ajax submit to check availability), all the fields in the first form are injected (prepend) into the second ?
Actually, only the first form is correctly validated but the second returns
Code:
Cannot read property 'options' of undefined
when running
Code:
	$('#formCreate2').form({
		onSubmit: function(){
			if( $('input#phone').val().length < 10 && $('input#phone_mobile').val().length < 10	){
				$.messager.alert( 'Attention', 'Vous devez entrer au moins un numéro de téléphone !');
				return false;
			}
			return $(this).form('validate');
		},
		success: function(data){
			return false;
		}
	});
in the second form !

Thanks a lot. This solves the issue I mentioned. However, it creates one side effect...if my form has a combo box as below:
Code:
<input type="text" id="locCode" name="loc" class="form-control easyui-combobox" placeholder="Location Code"
                               data-options="
                                    required:true,
                                    width:320,
                                    height:34,
                                    url:'register.php?action=load',
                                    method:'get',
                                    valueField:'id',
                                    textField:'locationName',
                                    panelHeight:'auto',
                                    formatter: formatItem" />

On executing $.parser.parse(ff); it is un-setting the user selected value from combobox. Can you suggest any fixes for this? Thanks again in advance.

Please set the 'value' property for combobox to set the initialized value.
Code:
<input type="text" id="locCode" name="loc" class="form-control easyui-combobox" value="..." ...>
Also, you can set the data item with 'selected' property set to true for the returned json array from 'register.php?action=load'. The data may looks like this:
Code:
[{
	"id":1,
	"text":"Java"
},{
	"id":2,
	"text":"C#"
},{
	"id":3,
	"text":"Ruby",
	"selected":true
}]

Hi,
Sorry about reviving this old topic. But I am stuck again at a similar problem.

You have suggested to set the value or set selected property to 'true' in json array. But if this is not an edit form, I simply need to load the data in the combobox with no pre-defined initialized value. Now if user selects a value from the combobox for inserting in DB for first time, on submit I am executing $.parser.parse(ff); but it is un-setting the user selected value from combobox. Please advise on how this can be resolved. Thanks in advance.
