问题描述
我想知道如何使用 js 在我的代码中选择 spcecific 'srcset'.这是我实际上不起作用的 js 代码:
I would like to know how to select spcecific 'srcset' in my code using js. This is my actually not working js code :
var imgPath = $('.wp-post-image').attr('srcset');
$('.tax-product_tag .breadcrumbs').css('background', 'url(' + imgPath + ')');
这里是 HTML :
<img width="300" height="300" src="//agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-300x300.jpg" class="attachment-woocommerce_thumbnail size-woocommerce_thumbnail wp-post-image" alt="" srcset="//agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-300x300.jpg 300w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-150x150.jpg 150w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-768x768.jpg 768w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-1024x1024.jpg 1024w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-575x575.jpg 575w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-190x190.jpg 190w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-370x370.jpg 370w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-600x600.jpg 600w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-100x100.jpg 100w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-400x400.jpg 400w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-900x900.jpg 900w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-675x675.jpg 675w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-286x286.jpg 286w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-450x450.jpg 450w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine-1080x1080.jpg 1080w, //agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine.jpg 1500w" sizes="(max-width: 300px) 100vw, 300px">
js 代码正在使用 'src' 属性，但这是选择 300x300 jpeg，我想获取原始 jpeg ( agothegoodlifestore.com/wp-content/uploads/2018/04/la-mericaine.jpg )

推荐答案
$('img').each(function(){ //for loop all images
var srcset=$(this).attr('srcset'); //attribut value
var srcset_arr=srcset.split(', '); //value to array
for(var key in srcset_arr){ //loop array
if(key==srcset_arr.length-1){ //find last element
var orig_image=(srcset_arr[key]).split(' ')[0]; //first element of sub array
console.log(orig_image);
}
}
