问题
I have one page that contains search page iframe . If you try to search for a text it will rarely fit the page.
I don't know what code to use to auto resize iframe based on content changes.
Right now I use this code in iframe :
<body onload="parent.alertsize(document.body.scrollHeight);">
And this javascript in parent page :
<script>
function alertsize(pixels){
pixels+=32;
document.getElementById('my-iframe').style.height=pixels+"px";
}
</script>
回答1:
<script type="text/javascript">
var myHeight = 0;
setInterval(function(){
if(myHeight != document.body.scrollHeight){
myHeight = document.body.scrollHeight;
parent.alertsize(myHeight);
}
},500);
</script>
