全高div不起作用

Question

我正在使用下面的代码来尝试设置我的 div 高度，以便它们都相等，取决于给定的最高 div。但是我的框仍然显示为下图 - 我已经发出警报并且正在触发，所以我知道我的 jQuery 正在工作：

问题：

jQuery:

$(document).ready(function() {
    var max = -1;
    $('.menuBoxesParagraph > div').each(function() {
    var h = $(this).height(); 
    max = h > max ? h : max;

    $(this).css({'min-height': max});
  });
 });

HTML：

<div class="menu1 menuBoxesParagraph">
    <p><span class="menu1Title"></span></p>
    <p>Content</p>
</div>

CSS：

.menuBoxesParagraph{
    width: 25%;
    border: 10px solid #000;
    margin: 2% 1% 0px 0px;
    padding: 5px;
    text-align: center;
}
.menuBoxesParagraph:before, .menuBoxesParagraph:after { content: ""; display: table; }
.menuBoxesParagraph:after { clear: both; }
.menuBoxesParagraph { zoom: 1; }

Answer 1

希望这能解决您的问题（JS）：

    var max = -1;
    $('.menuBoxesParagraph').each(function() {

    var h = $(this).height(); 
    max = h > max ? h : max;

  });


$(".menuBoxesParagraph").css("height",max+"px");

我猜有两件事，一是你在选择器menuBoxesParagraph > div 中使用了一个不存在的 div。 因为那个最大值总是-1。 高度也缺少“px”值。

只需添加以下JQUERY：-

$(document).ready(function(){  
    var max = -1;
    $('.menuBoxesParagraph > div').ready(function() {
        var h = $(this).height(); 
        max = h > max ? h : max;
        alert(h+"--"+max);    
        //$(this).css({'min-height': max});
        $(".menuBoxesParagraph").css("height",max+"px");
    });
});

DEMO

$(document).ready(function () {
  var highestBox = 0;
  $('.menuBoxesParagraph').each(function () {
    if ($(this).height() > highestBox) highestBox = $(this).height();
  });
  $('.menuBoxesParagraph').height(highestBox);
});
