私はこのコードを使用していますが、値が「未定義」であると誰かが私に問題を指摘できますか?
これは私のJavaクラスコードです
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(com.frux.web.R.layout.activity_main);
String value = "Isiah";
WebView web = (WebView) findViewById(R.id.web1);
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("file:///android_asset/www/index.html");
web.loadUrl("javascript:setValue(\""+ value +"\")");
}
これは私のウェブページコードです
<!DOCTYPE html>
<html>
<head>
</head>
<body>
Whats your Name?
<input id="name" value="" />
<button onclick = "setValue()">Submit</button>
<script type="text/javascript">
function setValue(value){
var myValue = value;
document.getElementById("name").value = myValue;
}
</script>
</body>
</html>
これもやってみます
web.loadUrl("javascript:setValue('"+ value +"')");
どんな考えでも高く評価されます
私はこのHTMLコードのコードを使用しましたが、上記の他のコードとは異なり、何も表示されません。
