webSocket Demo
- 使用工具:WebBrowser
- 传输参数:delphi 给js 赋值JSON字符串,js 接收到后通过JSON.parse()方法转换成JSON对象,然后根据需要参数进行读取, Delphi 通过SuperObject 处理JSON数据
- 调用JSON方法:WebBrowser1.oleObject.document.parentWindow.execScript('js方法名','JavaScript')
- 设置js变量 :WebBroser1.oleObject.document.Script.str:='newvalue'; str为js定义变量
- Delphi 触发html 中的Button 单击事件:WebBrowser1.OleObject.document.getElementById("按钮id").click;
