我的Yii2表单中有两个文本框-mrp,rate。我想要的是,当用户以mrp为单位键入金额时,将在费率中填充10%的折现值。假设用户在mrp中输入100,则rate中填充的值将为90。这将显示小数点后2位,即90.00。
我的代码如下-
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
/* @var $this yii\web\View */
/* @var $model frontend\modules\batchno\models\Productbatch */
/* @var $form yii\widgets\ActiveForm */
?>
<div class="productbatch-form">
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'productname')->textInput(['maxlength' => true]) ?>
<?= $form->field($model, 'batchno')->textInput(['maxlength' => true]) ?>
<?= $form->field($model, 'mfgdate')->textInput() ?>
<?= $form->field($model, 'expdate')->textInput() ?>
<?= $form->field($model, 'mrp')->textInput() ?>
<?= $form->field($model, 'rate')->textInput() ?>
<div class="form-group">
<?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
<?php
$ this->RegisterJs ( "
$('#Productbatch-mrp').keyup(function(){
var total = this.value;
var percent = 10;
var discount_value = (total / 100) * percent;
$('#Productbatch-rate').val(discount_value);
});
});
" , View :: POS_END);
?>
最佳答案
您应该在jQuery代码选择器中尝试使用Html::getInputId($model, 'mrp')
代替Productbatch-mrp
。希望它能对您有所帮助。
<?php
$this->RegisterJs ( "
$('document').ready(function(){
$('#".Html::getInputId($model, 'mrp')."').keyup(function(){
var total = this.value;
var percent = 10;
var discount_value = (total * percent) / 100 ;
var rate = total - discount_value;
$('#".Html::getInputId($model, 'rate')."').val(rate);
});
});
", View::POS_END);
?>
