Question

我不想提交表单但我想获取输入字段的值并通过ajax将其发送到控制器以保存在数据库中。我有以下JS代码，以帮助我获取输入字段的内容，并在用户输入3秒后发送到服务器端

<?php
$script = <<< JS
$(document).ready(function(){
    //setup before functions
    var typingTimer;
    var doneTypingInterval = 3000;
    var \$TitleInput = $('#product-product_title');

    //on keyup, start the countdown

    \$TitleInput.on('keyup input change paste',function(){
        clearTimeout(typingTimer);
        if (\$TitleInput.val()) {
            typingTimer = setTimeout(doneTyping, doneTypingInterval);
        }
    });
    //user is "finished typing," do something
    function doneTyping () {

        data = \$TitleInput.val();

        $.ajax({
            url: '/trobay/draft/create',
            type: 'POST',
            data: data,
            success: function (data) {
                alert(data)
            },
            error: function(jqXHR, errMsg) { 
                // handle error
                alert(errMsg);
            }
        });
    }
});
JS;
$this->registerJs($script);
?>

在我的控制器中我有这个

public function actionCreate()
{
    $model = new Draft();

    if ($model->load(Yii::$app->request->post())) {
        $model->created_at = \time();
        if($model->save()){
            echo draftId;
        }else{
            echo '0';
        }

    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

如果标题草稿成功保存，我想回复draftid 如何使这项工作得到任何帮助

以下是我的观点

<?php $form = ActiveForm::begin([
    'id' => $model->formName(),
    'enableClientValidation' => true,
    'fieldConfig' => ['template' => '{label}{input}{hint}']
]); ?>
    <div class="row">
        <div class="col-md-12">
            <?= $form->field($model, 'product_title')->textInput([
                'class' => 'title-input',
                'placeholder' => 'Give us a title for your items(include size,brand,color,material. e.t.c)',
            ])->label(false) ?>
        </div>
        <div class="col-md-12 text-muted">E.g Men's blue addidas glide running shoes size 11 </div>
    </div>
    <?= $form->field($model, 'user_id')->textInput() ?>

    <?= $form->field($model, 'product_name')->textInput(['maxlength' => true]) ?>

    <?= $form->field($model, 'product_description')->textarea(['rows' => 6]) ?>

    <?= $form->field($model, 'category_id')->textInput() ?>

我在我的视图中有这个但我想只保存用户输入值3秒后第一个输入字段的值

尝试使用此JS，但在ID表单上更改$('#form')

$(document).ready(function(){
    //setup before functions
    var typingTimer;
    var doneTypingInterval = 3000;
    var $form = $('#form');

    //on keyup, start the countdown

    $form.find('input[type="text"]').on('keyup input change paste',function(){
        clearTimeout(typingTimer);
        if ($(this).val()) {
            typingTimer = setTimeout(doneTyping, doneTypingInterval);
        }
    });
    //user is "finished typing," do something
    function doneTyping () {
        $.ajax({
            url: '/trobay/draft/create',
            type: 'POST',
            data: $form.serialize(),
            success: function (data) {
                alert(data)
            },
            error: function(jqXHR, errMsg) { 
                // handle error
                alert(errMsg);
            }
        });
    }
});
