关于onpropertychange与oninput的用法，网上一大堆，但还是有不兼容的时候，比如说，我想计下，一个input的值改变了多少次，如果写成兼容写法就为
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>onpropertychange与oninput事件</title>
<script type="text/javascript">
window.onload = function(){
oTxt1 = document.getElementById('input1');
oTxt2 = document.getElementById('input2');
oBtn = document.getElementById('btn');
var i=0;
oTxt1.oninput = oTxt1.onpropertychange = function(){
console.log(arguments.length)
for(var j = 0; j< arguments.length; j++){
console.log(arguments[j])
}
i+=1
oTxt2.value = i
}
oBtn.onclick = function(event){
var oEvent = window.event || event;
oTxt1.setAttribute('good','hello')
}
}
</script>
</head>
<body>
<input type="text" placeholder='请输入……'/>
<input type="text" placeholder='请输入……'/>
<button value="changeProperty" >改变属性</button>
</body>
</html>
