这些可见性设置适用于除Safari之外的所有浏览器。我正在试图找出原因而失去理智。 JS脚本位于html部分。我知道代码通过“if（pass == true）{”部分，因为当我添加它时会弹出一个javascript警告通知。它似乎完全忽略了可见性设置。
请帮忙！哈哈
更新：它开始看起来像是php信息处理我的表单的方式有问题。如果我在上传文件时点击“提交”后点击“停止”，则可见性设置生效。在进行文件上传之前，每个其他浏览器似乎都会更新可见性设置。为什么safari会等待文件先完成上传？
编辑：添加了完整的JavaScript，以便您可以看到我的文件上传检查
编辑：添加了我的表单和php检查信息，以查看表单是如何接收此脚本的

我刚刚在Safari中试过它，它似乎有效。也许在他们开始工作之前简化一些事情？
function formcheck() {
var pass = true;
if (pass == true) {
document.getElementById('i_submit').style.visibility = 'hidden';
document.getElementById('patience').style.visibility = 'visible';
}
}<div>
<input style="visibility:visible;" type="submit" value="Send" id="i_submit" onclick="formcheck();">
</div>
<div id="patience" style="visibility:hidden;">
<h4 style="font-style:italic; font-size:20px;">
... UPLOADING ...
</h4><br>
<h4 style="font-style:italic; font-size:14px;">
Please be patient
</h4>
</div>

您可能想尝试
document.getElementById('i_submit').setAttribute('style','display: none');
