javascript - 如果我以像素为单位设置表格的内容宽度，表格的 <td> 会变宽

标签 javascript jquery html css

我有一张大 table ，里面有很多小 table 。我需要在这些小表格中放置一些内容，但是当我这样做时，一些 td's 改变了它的大小，使其他的太窄了。这是 fiddle :

https://jsfiddle.net/vaxobasilidze/jwvzpt62/14/

我需要放在表格中的内容是一个div .placeHolder，它有一个红色边框。如您所见，当我以像素为单位设置 .placeHolder 的宽度时会出现问题。如果宽度为 100%，它会正常工作。我该如何解决？设置 min-width 没有帮助。在第一个表格宽度为 100% 时，一切正常，但在第二个表格宽度中设置为像素。尽管有足够的像素空间，.placeHolder 仍然使其父 td 变宽并弄乱了音频 block 。

for(var i=1; i<=3; i++){
	var blockId = "channel"+i;
	var aspect = "16:9";
  var aspX = parseInt(aspect.split(':')[0]);
  var aspY = parseInt(aspect.split(':')[1]);
  var width = $('#'+blockId).closest('.channels').find('.vid').width();
  var height = $('#'+blockId).closest('.channels').find('.vid').height();
  var test = (width/aspX)*aspY;
  var test2 = (height/aspY)*aspX;
  if(test <= height){
    $('#'+blockId).closest('.channels').find('.placeHolder').css({'height': test+'px'});
  }
  else {
    $('#'+blockId).closest('.channels').find('.placeHolder').css({'width': test2+'px'});
  }
}

最佳答案

在您的代码中，您将 px 与 % 混合使用。不要那样做!它扰乱了浏览器中的布局计算。我建议仅使用 % 来指定列宽，并确保所有列的总宽度始终为 100%。
