Question

我需要在类名为termPanel的div组中找到最大div的高度。如何访问每个＆＃39; termPanel＆＃39;数组中的div？

 function resizePanelsToBiggest(){

        var maxheight = 0;

        var terms = $('.termPanel');

        for(var i = 0;i<terms.length;++i){

            if(maxheight < terms[i].height){
                maxheight = terms[i].height;
            }


        }

    }

Answer 1

使用Math.max.apply

function resizePanelsToBiggest() {
  var maxheight = 0;
  var terms = $('.termPanel');
  var allH = terms.map(function() {
    return $(this).height();
  }).get();
  var maxH = Math.max.apply(null, allH);
  console.log(maxH);
}

查看此演示：

 resizePanelsToBiggest();
 
 function resizePanelsToBiggest() {
     var maxheight = 0;
     var terms = $('.termPanel');
     terms.each(function(ndx){
     	if ($(this).height() > maxheight) {
        	maxheight = $(this).height();
        }
     });
     console.log(maxheight);
 }

.termPanel {
    width: 90px;
    display: inline-block;
    vertical-align: top;
    color: white;
}

.termPanel:nth-of-type(even) {
    background: black;
}

.termPanel:nth-of-type(odd) {
    background: red;
}

.termPanel:nth-of-type(1) {
    height: 100px;
}

.termPanel:nth-of-type(2) {
    height: 250px;
}


.termPanel:nth-of-type(4) {
    height: 400px;
}

<div class="termPanel"></div>

Answer 3

这种方式对我来说似乎更简单易懂：

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="termPanel" style="float:left;width:50px;border:2px solid red"></div>
<div class="termPanel" style="float:left;width:50px;border:2px solid green"></div>
<div class="termPanel" style="float:left;width:50px;border:2px solid blue"></div>
<div class="termPanel" style="float:left;width:300px;border:2px solid red">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ut temporibus reiciendis officia veniam quos id velit quibusdam, asperiores ipsum. Obcaecati illum, hic facere repellat dolor modi commodi eum tenetur voluptas veritatis expedita consequuntur repellendus provident error, nisi quos! Aliquid error consectetur voluptates ea dicta, vero, dolores numquam, rerum quasi molestias nemo....</div>

＆＃13;

public void deleteMessage(int position){
    MessageViewHolder messageViewHolder= (MessageViewHolder) recyclerView.findViewHolderForAdapterPosition(position);
    messageViewHolder.linearLayout.setVisibility(View.GONE);
    messageViewHolder.tvDateSending.setVisibility(View.GONE);

}

＆＃13;
