Question

在我的php页面上我想点击页面加载时的按钮。我用jQuery和JS测试过它。虽然jQuery不起作用，但JS工作正常。

知道为什么会这样吗？

jQuery的：

public function run() {
    $path = base_path().'/database/seeds/sql/data.sql';
    $sql = file_get_contents($path);
    DB::unprepared($sql);
}

JS：

<script>
$(document).ready(function() {
    $('#button_id').click();
    $('#button_id').trigger('click');
});
</script>

我要点击的按钮里面有一个<script> window.onload = function() { document.getElementById('button_id').click(); }; </script>。这可能是问题吗？

data-filter

编辑：

控制台中没有错误，顶部添加了libary。

如果我记录两个按钮，这是我的控制台输出：

Answer 2

$（ '＃button_id'）点击（）;

您没有定义任何点击处理程序 - 因此不会发生任何事情。您需要在其中删除一个函数以用作回调。像这样：

 $( "#button_id" ).click(function() {
    $(this).trigger('click');
 });

听起来你还没有把jquery脚本包含在脑中

<head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>

jquery .click（）不起作用
