import win.ui; /*DSG{{*/ var winform = win.form(text="aardio form";right=199;bottom=239) winform.add( button={cls="button";text="Button";left=32;top=144;right=128;bottom=184;z=1} ) /*}}*/ import web.sciter import web.sciter.debug; var wb = web.sciter( winform ) wb.attachEventHandler( web.sciter.debug ); wb.html = /** <!doctype html> <html> <head> <META http-equiv="Content-Type" content="text/html; charset=utf-8"> <script> class Hello extends Element{ render(){ return <div class="test">hello</div> } ["on eventName"](evt){ console.log("事件被触发了") this.innerText = evt.data; } } document.body.content(<Hello />) </script> <style type="text/css"> html,body{ height:100%; margin:0; } </style> </head> <body> </body> </html> **/ winform.button.oncommand = function(id,event){ wb.querySelector(".test").fireEvent("eventName", "来自 aardio 的数据") } winform.show(); win.loopMessage();
使用场景, 一个自定义事件相当于订阅器, aardio 触发订阅器让 sciter 更新界面
注意:后端通知前端更新界面,不建议这种针对某个前端节点去通知,应该用全局事件, 查看 https://chengxu.xyz/t/21339
