Yii2新闻未显示在更新中

Question

我目前正在尝试在yii2中创建的新闻模块有问题。

我有多个与动物产品或植物产品有关的领域。与动物无关的项目将不会显示，反之亦然。

现在，它在创建时效果很好，但在更新中却没有显示。

newsscript.js

    public function getDepartment0()

我知道只学习javascript和jquery的代码很乱。关于如何进行的任何建议？或有更好的方法我们非常感谢您的帮助。

Answer 1

我会在每个函数的关键位置添加很多console.log（“我在函数x中，正在执行y”）键入注释。接下来，在Chrome中按F12键，以查看控制台调试器，并查看是否要撤消多次隐藏操作。

示例：JavaScript控制台

function makeIconFromHex() {
    console.log('makeIconFromHex..............');
    console.log(matrix);

    var width = matrix[0].length;
    var height = matrix.length;
}

另外，也许像这样更好：

<?= $form->field($model, 'somefield')
    ->textInput(['hidden'=> $model->isNewRecord ? false : true])
    ->label(false) ?>
