<html lang="en" class="no-js"><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <title> 文本框测试 </title> <body> <p><label><input type="checkbox" id="checkbox"> Checked</label> <p><button id="button">Click me</button> <script> function simulateClick() { var evt = new MouseEvent("click", { bubbles: true, cancelable: true, view: window, }); var cb = document.getElementById("checkbox"); //element to click on var canceled = !cb.dispatchEvent(evt); if(canceled) { // A handler called preventDefault //alert("canceled"); } else { // None of the handlers called preventDefault //alert("not canceled"); } } document.getElementById("button").addEventListener('click', simulateClick); setTimeout(function () { var pass=document.getElementById("button"); var event=new MouseEvent("click",{ view:pass.ownerDocument.defaultView, bubbles: true, cancelable:true }); pass.dispatchEvent(event); },1000); </script>
