我正在创建一个带有同意和不同意按钮的 HTML 启动页面。当用户单击同意按钮时，我无法重定向到 URL。

例子

<head>
<meta http-equiv="Pragma" content="no-cache">
<meta HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1">
<title> TITLE </title>
<script>

function submitAction(){
  var link = document.location.href;
  var searchString = "redirect=";
  var equalIndex = link.indexOf(searchString);
  var redirectUrl = "";

  if (document.forms[0].action == "") {
  var url = window.location.href;
  var args = new Object();
  var query = location.search.substring(1);
  var pairs = query.split("&");
      for(var i=0;i<pairs.length;i++){
          var pos = pairs[i].indexOf('=');
          if(pos == -1) continue;
          var argname = pairs[i].substring(0,pos);
          var value = pairs[i].substring(pos+1);
          args[argname] = unescape(value);
      }
      document.forms[0].action = args.switch_url;       
  }       
  if(equalIndex >= 0) {
        equalIndex += searchString.length;
        redirectUrl = "";
        redirectUrl += link.substring(equalIndex);
  }
  if(redirectUrl.length > 255)
  redirectUrl = redirectUrl.substring(0,255);
  document.forms[0].redirect_url.value = redirectUrl;
  document.forms[0].buttonClicked.value = 4;
  document.forms[0].submit();
}

function reject()
{
alert("You will not be able to access the system!");
}


function loadAction(){
  var url = window.location.href;
  var args = new Object();
  var query = location.search.substring(1);
  var pairs = query.split("&");
  for(var i=0;i<pairs.length;i++){
      var pos = pairs[i].indexOf('=');
      if(pos == -1) continue;
      var argname = pairs[i].substring(0,pos);
      var value = pairs[i].substring(pos+1);
      args[argname] = unescape(value);
  }
  document.forms[0].action = args.switch_url;

}

我将使用Window.location，请参阅此页面以查看示例：

http ://www.w3schools.com/js/js_window_location.asp

在 HTML 中，您可以使用：

onclick="返回submitAction();"

并在函数 submitAction() 的末尾写入return true；取消提交或返回false；允许提交。

在 JavaScript 中，使用window.location.assign(URL)方法，例如

function redirect(url)
{
window.location.assign(url);
}
