我对编程的经验很少，但已被要求仅使用Javascript在客户站点上隐藏一行表。我知道如何使用HTML或CSS执行此操作，但已被告知我无法访问我们正在使用的第三方平台中的这些元素，并且必须为其创建脚本。
我在http://jsfiddle.net/zcho5zs5/输入了html，可以使用任何帮助来隐藏整个第二行。所有应该显示的是＆＃34;选择付款方式＆＃34;和＃34;通过已存卡支付＆＃34;随着下拉菜单。下面的所有内容都需要隐藏。

的Javascript？
我已尝试过在本网站上发现的类似功能的一些建议，但似乎没有任何效果。

下面是javascript代码，用于隐藏包含“通过信用卡付款”的特定行。
它在display:none上设置CSS样式<tr>，ID为“t1_t2_c_p_rowCreditCard”。
document.getElementById('t1_t2_c_p_rowCreditCard').style.display='none';
document.getElementById('t1_t2_c_p_rowCreditCard').style.display = 'none';<div id="t1_t2_c_p_pnlPaymentMethod">

window.onload函数中的Javascript将在页面加载后执行，导致元素被隐藏之前出现延迟。另一方面，CSS不需要DOM就绪。
我看到您使用<script>标记添加了javascript。您提到您不能使用CSS，但是，如果您可以使用<script>标记，那么您也可以使用<style>标记：
<style type="text/css">
tr#t1_t2_c_p_rowCreditCard {display:none;}
</style>
<style type="text/css">
tr#t1_t2_c_p_rowCreditCard {
display:none;
}
</style>
