jquery砌体风格网格

Question

我想用jquery构建一个砌体风格的布局和位置元素。遍历元素时，我试图重置列位置，一旦该行已成为3列宽，但是这个代码不工作，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个顶部。

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

我觉得应该是

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

}else{ 
    rowPos += elementWidth; 
} 

Answer 2

请看看这种方法。能够同时管理箱的顶部位置：

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++; 
 
    } 
 
    }); 
 

 
});
