【问题描述】:

抱歉,PHP 新手,我正在尝试进行 curl 表单提交,但希望在第一次提交后保留结果。然后这些显示按钮,并根据单击哪个按钮,另一个提交在弹出窗口中显示第二个值。它正确地将值传递给弹出窗口,但我不希望在单击第二次提交时刷新屏幕。

欢迎指点

【问题讨论】:

  • 如果您不想在提交时出现“屏幕刷新”,您需要考虑制作Asynchronous Request
  • 感谢我正在尝试执行异步 http 请求,但无法使其正常工作

标签: javascript php forms curl xmlhttprequest


【解决方案1】:

如果您不想刷新页面,您应该拨打AJAX 电话。

为了让生活更轻松,您可以使用jQuery's POST

    【解决方案2】:

    我正在尝试使用 httpRequest 异步执行,但没有返回任何内容? API 说返回可以是文本、HTML 或 XML。我都试过了。

    <SCRIPT TYPE="text/javascript">
    
    function httpGetAsync()
      {
       var xmlHttp = new XMLHttpRequest();
            xmlHttp.open("GET", "URL....", true);
            xmlHttp.send( null );
    alert(xmlHttp);
     alert(xmlHttp.responseText);
        return xmlHttp.responseText;
    }
      </SCRIPT>
