模拟一个等待函数
var js = /** const sleep = (time) => { return new Promise(resolve => setTimeout(resolve, time)) } async function sleepAsync(time) { await sleep(time) } sleepAsync(%s) **/ var wait = function(ms){ return cdp.Runtime.evaluate( awaitPromise = true; // 执行是否应该等待结果值,并在等待的承诺被解决后返回。 expression = string.format(js, ms) ) }
测试等待5000毫秒
import win.ui; /*DSG{{*/ var winform = win.form(text="aardio form";right=385;bottom=140) winform.add( button={cls="button";text="运行";left=142;top=43;right=221;bottom=83;z=1} ) /*}}*/ io.open() import aaz.chrome.dp; var cdp, err = aaz.chrome.dp() if(!cdp){ winform.msgboxErr(err); return ; } var js = /** const sleep = (time) => { return new Promise(resolve => setTimeout(resolve, time)) } async function sleepAsync(time) { await sleep(time) } sleepAsync(%s) **/ var wait = function(ms){ return cdp.Runtime.evaluate( awaitPromise = true; // 执行是否应该等待结果值,并在等待的承诺被解决后返回。 expression = string.format(js, ms) ) } cdp.timeout = 20000; var task = function(){ // 打开浏览器 var ok, err = cdp.open() if(!ok){ io.print("打开浏览器失败", err); return ; } // 连接浏览器 var ok, err = cdp.connect(); if(!ok){ io.print("连接浏览器失败", err); return ; } // 订阅 Page 事件 cdp.Page.enable(); // 打开网址 cdp.Page.navigate( url = "https://www.baidu.com"; ) // 等待页面加载完成 cdp.waitEvent( "Page.loadEventFired" ); io.print("等待开始") var tick = time.tick() wait(5000) io.print("等待结束,用时:", time.tick()-tick ) // 关闭浏览器 cdp.Browser.close(); } winform.button.oncommand = function(id,event){ cdp.run( task, function(){ winform.button.disabled = true }, function(){ winform.button.disabled = false } ) } winform.show(); win.loopMessage();
