如何在android系统调用多个Java脚本函数更以时间来加载web视图？ [英] How to call more than one java script function at a time in android to load the webview?

问题描述

我有一个简单的Java脚本file.below是我的样本的js code

i have a simple java script file.below is my sample js code

自动播放功能（VIDEOID，ST，EN）{
            player.loadVideoById（{'VIDEOID'：VIDEOID，'startSeconds'：ST，'endSeconds'：恩，'suggestedQuality'：'小'}）;
            player.playVideo（）;
        }

function autoplay(videoId, st, en) { player.loadVideoById({ 'videoId': videoId, 'startSeconds': st, 'endSeconds': en, 'suggestedQuality': 'small' }); player.playVideo(); }

    function getState(){
      alert(player.getPlayerState());
        return player.getPlayerState();
    }

    function CallTweak()
    {
      alert(player.getPlayerState());
      document.getElementById("mytext").innerHTML = player.getPlayerState();
      var data=player.getPlayerState();
       AndroidFunction.showToast(data);
      alert('second alert');
    }

我调用一个函数，它工作正常，但我试图调用，例如自动播放（）和CallTweak（）不叫这些方法两种功能。
下面是样本code调用函数

i calling one function it works fine but i am trying to call two functions for example autoplay() and CallTweak() those methods are not called. below is sample code for calling the functions

web_view.loadUrl（JavaScript的：CallTweak（））;
web_view.loadUrl（JavaScript的：自动播放（））;

web_view.loadUrl("javascript:CallTweak()"); web_view.loadUrl("javascript:autoplay()");

如何在同一时间在一个单一的按一下按钮在Android中调用多个函数？先谢谢了。

推荐答案

取两种方法之一

无论哪种，在你的JavaScript code，确定了第三函数，它们调用其他两个

Either, in your javascript code, define a third function which calls the other two

function callBothFunctions(){
    CallTweak();
    autoplay();
}

然后再调用第三个功能

and then call that third function

web_view.loadUrl("javascript:callBothFunctions()");

或，另一种方法是使用像

Or, the other approach is to use an anonymous self-executing function like

 string javascriptFunctionCall = 
                      "javascript:"
                      + "(function(){"
                          + "CallTweak();"
                          + "autoplay();"
                      +"})()";

 web_view.loadUrl(javascriptFunctionCall);
