Q : how to add a data value into the label of table’s row by ajax?

status : add a new row into table of form is working. at then, when the user choose the item, the price should be show at the label(price). return from controller is fine. but the price didn’t show at label(price).

This is my view

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'acc-recei-form',
    'enableAjaxValidation'=>false,
)); ?>

    <p class="note">Fields with <span class="required">*</span> are required.</p>

    <?php echo $form->errorSummary($model); ?>
   <?php
    Yii::app()->clientScript->registerScript('add-item', "
        $('#add-item').click(function(){
            //console.log(item_template);
            $('#template .template_item').clone().appendTo('#item_list');
            $('#item_list .template_item').fadeIn();
            return false;
        });

        $('#AccRecei_acc_category_id').live('change', function(){
                                                               var itemID = $(this).val(),
                    vNode  = $(this);
                    $.ajax({
                  url: 'getitem/'+itemID,
                  dataType: 'json',
                  success: function(data){
                    var target = $(vNode).parents('tr');
                    alert(target);
                    $(target).find('.price').val(data.item_price);
                  }
                });
                //alert(vNode);
            });
");


    ?>
<table id="item_list">
<tr>
    <td>name</td>
    <td>price</td>
    <td>qty</td>
    <td>row_total</td>
<tr>
</table>
<!--- other fields -->

<div class="row buttons">
    <?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?>
</div>

<?php $this->endWidget(); ?>

</div><!-- form -->

<table id="template" style="display:none;" >
<tr class="template_item">
    <td><?php
            echo $form->dropDownList($model,'acc_category_id', $accitemslist, array(
            'prompt'=>'Please select a category',
            'options'=>array("$model->acc_category_id"=>array('selected'=>'selected')),
            )
        ); 
        ?></td>
    <td><label id="price" class="price"></label></td>
    <td><input type="text" name="item_qty[]" class=".qty" /></td>
    <td><label id="row_total" class="row_total[]"></label></td>
<tr>
</table>

This is the controller (call from ajax)

public function actionGetitem()
    {
        echo CJSON::encode(array(
            'item_price'=>12, 
        ));
    }

Answer 1

a ‘label’ tag doesn’t have a ‘value’. Try using ‘text()‘ instead.
