How to use JS to solve the problem that ie6 does not support max-width and max-height

This article mainly introduces how to use JS to solve the problem that ie6 does not support max-width and max-height. Friends in need can come here for reference. I hope it will be helpful to everyone.

Today I encountered a problem about using js to solve the problem of ie6 not supporting max-width and max-height. I just started using jQuery to implement it, but I couldn’t get the value in css, such as:

  if($.browser.msie && $.browser.version == 6.0)
  {
    var maxWidth = parseInt($('.viewBigPic img').css('max-width'));
    $('.viewBigPic img').each(function(){
      if ($(this).width() > maxWidth)
        $(this).width(maxWidth);
    });
  }

I don’t know why, but I can’t get the maximum value in css, so I can only use native js to achieve it

The js code is as follows:

The html code of the

<script type=&#39;text/javascript&#39;>
function setPhotoSize(elem, width, height) {
<!--[if IE 6]>
try{
var image=new Image();
image.src=elem.src;
if(image.width>0 && image.height>0){
var rate = (width/image.width < height/image.height)? width/image.width : height/image.height;
if(rate <= 1){
elem.width = image.width*rate;
elem.height = image.height*rate;
}
else {
elem.width = image.width;
elem.height = image.height;
}
}
}catch(e){}
<!--[endif]--> 
}
</script>

part is as follows:

<p class="viewBigBox">
  <p class="viewBigPic">
     <p><img id="imgid" onload="setPhotoSize(this,730,470)" src="images/viewShow.jpg" alt=""/></p>
  </p>
</p>

css style is as follows:

.viewBigBox{ border:1px solid #e3e3e3; background-color:#ffffff; padding:1px;  margin-top:18px;}
.viewBigPic{ background-color:#f7f7f7;padding:20px 14px;}
.viewBigPic p{display:table-cell;width:730px; line-height:470px; overflow:hidden; vertical-align:middle; text-align:center; height:470px;*font-size:390px;}
//实现图片垂直居中，主要运用了font-size与height的比例
.viewBigPic p img{ vertical-align:middle; max-height:470px; max-width:730px;}
