下面是PHP页面的链接。在页面加载之前如何运行进度条?当前,它在页面完全加载后加载。我希望在用户在浏览器中输入URL后立即运行此操作。默认情况下,PHP只会在完成后将HTML/输出发送到浏览器。这就是为什么在页面完成加载之前,您不会看到进度条。有两种方法可以解决这个问题:
您最好选择选项2,因为这是目前更为普遍接受的web应用程序标准。尝试在window.load函数中运行进度条?您必须在不显示报告的情况下使用进度条显示页面,然后使用Ajax从另一个使用javascript的php页面获取报告。@freginold我认为您错误地删除了一些代码。您是否尝试过直接运行进度条(没有将其包装在
$(document.ready()
)?@Jarzon啊,您是对的。我不知道这是怎么发生的。现在修好它。谢谢
