Question

我正在尝试使用jquery构建一个砌体样式布局和位置元素。迭代元素时，我试图重置列位置一旦行变为3列宽但这段代码不起作用我不明白为什么

var rowPos = 0;

$(document).ready(function(){

  $('.box').each(function(ind){

    var elementWidth = $(this).width();
    var elementHeight = $(this).height();

    $(this).css({

        left: rowPos +'px'
    });


    if(rowPos >= elementWidth * 2){
        rowPos === 0;

    }else{
        rowPos += elementWidth;
    }

    console.log(rowPos);
  });

});

这导致3列宽，其他元素堆叠在第三列之上。

CSS

body{
font-size: 20px;
}

.container{
position: relative;
}

.box{
width: 33.333%;
position: absolute;
color: #fff;
text-align: center;
box-sizing: border-box;

}
.box span{
margin-top: -1em;
position: relative;
top: 50%;
margin-top: -1em;
}

.box1, .box3, .box6, .box8{

height: 400px;

}

.box2, .box5{
height: 600px;
}
.box4, .box7{
height: 350px;
}

.container div:nth-child(odd){
background: #2a8d6f;

}
.container div:nth-child(even){
background: #5b3eac;

}

标记

<div class="container">
        <div class="box box1"><span>box 1</span></div>
        <div class="box box2"><span>box 2</span></div>
        <div class="box box3"><span>box 3</span></div>
        <div class="box box4"><span>box 4</span></div>
        <div class="box box5"><span>box 5</span></div>
        <div class="box box6"><span>box 6</span></div>
        <div class="box box7"><span>box 7</span></div>
        <div class="box box8"><span>box 8</span></div>

    </div>

Answer 1

我认为应该是

if(rowPos >= elementWidth * 2){
    rowPos = 0; //not rowPos === 0;

}else{
    rowPos += elementWidth;
}

Answer 2

请看一下这种方法。能够管理盒子的最高位置：

var rowPos = 0;
var counter = 0;
$(document).ready(function() {

  $('.box').each(function(ind) {

    var elementWidth = $(this).width();
    var elementHeight = $(this).height();
    var height = 0;
    var top = 0;
    if (ind >= 3) {
      var topBox = $('.box').eq(ind - 3);
      height = topBox.height();
      top = topBox.position().top;
    }
    $(this).css({
      left: rowPos + 'px',
      top: (height + top) + 'px'
    });


    if (counter >= 2) {
      rowPos = 0;
      counter = 0;
    } else {
      rowPos += elementWidth;
      counter++;
    }
  });

});
