从目前找到的资料来看,这个模拟不能起到所有的作用,主要体现在键盘的有一些事件不能完整的体现 出来
先做个记录吧。
//这个就是用来输入字科符的 var inpEle=document.getElementById("stockCode"); var st ='000001' var evt = new InputEvent('input', { inputType: 'insertText', data: st, dataTransfer: null, isComposing: false }); inpEle.value = st; inpEle.dispatchEvent(evt);
//敲回车 let keyCoke = 13 let keyboardEvent = document.createEvent('KeyboardEvent') let initMethod = typeof keyboardEvent.initKeyboardEvent !== 'undefined' ? 'initKeyboardEvent' : 'initKeyEvent' keyboardEvent[initMethod]('keyup', true, true, window, false, false, false, false, keyCoke, 0) document.getElementById('stockCode').dispatchEvent(keyboardEvent)
//不知道为什么弄的那个网站还得这样处理一下 function fireKeyEvent(el, evtType, keyCode) { var evtObj; if (document.createEvent) { evtObj = document.createEvent('UIEvents'); evtObj.initUIEvent(evtType, true, true, window, 1); delete evtObj.keyCode; if (typeof evtObj.keyCode === "undefined") {//为了模拟keycode Object.defineProperty(evtObj, "keyCode", { value: keyCode }); } else { evtObj.key = String.fromCharCode(keyCode); } if (typeof evtObj.ctrlKey === 'undefined') {//为了模拟ctrl键 Object.defineProperty(evtObj, "ctrlKey", { value: true }); } else { evtObj.ctrlKey = true; } el.dispatchEvent(evtObj); } } fireKeyEvent(document.getElementById('stockCode'),'keyup',13)
