在 Flutter Webview 中运行一些 Javascript [英] Run some Javascript in Flutter Webview

问题描述

如何在 flutter_webview_plugin 中运行 Javascript?我试过这个:

How can I run Javascript in flutter_webview_plugin? I tried with this:

onPressed: () {
   flutterWebviewPlugin.evalJavascript('<script language="JavaScript" type="text/javascript">alert("Hello World")</script>');
},

但什么也没发生.

我认为使用 flutterWebviewPlugin.evalJavascript 可以在 Web 视图中运行 Javascript.我做错了什么吗?

I thought with flutterWebviewPlugin.evalJavascript it's possible to run Javascript in a Webview. Did I do something wrong?

推荐答案

flutterWebviewPlugin.evalJavascript('<script language="JavaScript" type="text/javascript">alert("Hello World")</script>')

需要 JavaScript，而不是 HTML

expects JavaScript, not HTML

<script language="JavaScript" type="text/javascript">alert("Hello World")</script>

是 HTML.

试试

flutterWebviewPlugin.evalJavascript('alert("Hello World")')
