如果从webviewview调用else语句不能在javascript onclick()中工作?

[英]If else statement not working in javascript onclick() when called from android webview?

During onClick() function which has a if else statement inside it is not working properly from android webview. onClick()函数中,其中有一个if else语句,它在android webview中无法正常工作。 I have added the code below. 我在下面添加了代码。 Kindly provide your suggestion were I am missing it. 如果我错过了,请提供您的建议。 Thanks a lot. 非常感谢。

function exampleCall(message) { 

   if(navigator.userAgent.match(/Android/i)) {
      androidexampleCall(message);
   }

   if(navigator.userAgent.match(/iPhone|iPad|iPod/i)){
       iOSexampleCall(message);
   }                            
}

JS call: JS电话:

<div onclick="javascript:exampleCall('GameOn');">.... </div>

I guess the call that is not working is androidexampleCall(message) . 我想无效的通话是androidexampleCall(message)

Define a interface and add it to the webview on your activity, like: 定义一个界面并将其添加到您的活动的webview中,例如:

 Webview wv;
 //... 
 wv.addJavascriptInterface(new myJavaScriptInterface(), "CallToAnAndroidFunction");
 //...
 public class myJavaScriptInterface {
     @JavascriptInterface
     public void androidexampleCall(String message);{
        //code
     }
 }

On your Js code you should do the call as follows: 在您的Js代码上,您应该按如下方式进行调用:

 function exampleCall(message) { 

   if(navigator.userAgent.match(/Android/i)) {
     window.CallToAnAndroidFunction.androidexampleCall(message);
   }

   if(navigator.userAgent.match(/iPhone|iPad|iPod/i)){
     iOSexampleCall(message);
   }                            
}

Seems like you didn't enabled Javascript for your Webview: 好像你没有为你的Webview启用Javascript:

webview.getSettings().setJavaScriptEnabled(true);

EDIT: 编辑:

Tested your code with this Webview: 使用此Webview测试您的代码:

webview = (WebView)findViewById(R.id.webView1);
webview.getSettings().setJavaScriptEnabled(true);

webview.loadUrl("http://jonathanalbrieux.com/others/testagent.html");

Button buttonReload = (Button)findViewById(R.id.button1);
buttonReload.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

        webview.loadUrl("http://jonathanalbrieux.com/others/testagent.html");

    }
});

And this page: 而这个页面:

<html>
<head>

</head>
<body>
    <div id="clickable" onclick="test('a')">clickaqd</div>
    <script>

        function test(string){
            if(navigator.userAgent.match(/Android/i)) {
                var divClickable = document.getElementById("clickable");
                divClickable.innerHTML = string;
            }

        }
    </script>
</body>

And everything works correctly, maybe you have some problem in androidexampleCall function. 一切正常,也许你在androidexampleCall函数中有一些问题。
