,或许与您遇到的问题类似。
回答者palaѕн给出了该问题的处理方式:
You can try this:
var img = document.getElementById('your_div_id'), style = img.currentStyle || window.getComputedStyle(img, false), bi = style.backgroundImage.slice(4, -1).replace(/"/g, "");
// Get the image id, style and the url from it var img = document.getElementById('testdiv'), style = img.currentStyle || window.getComputedStyle(img, false), bi = style.backgroundImage.slice(4, -1).replace(/"/g, ""); // Display the url to the user console.log('Image URL: ' + bi);<div id="testdiv" style="background-image:url('http://placehold.it/200x200');"></div>
Edit:
Based on @Miguel and other comments below, you can try this to remove additional quotation marks if your browser (IE/FF/Chrome...) adds it to the url:
bi = style.backgroundImage.slice(4, -1).replace(/"/g, "");
and if it may includes single quotation, use: replace(/['"]/g, "")
