標籤：完全 大致 console utf-8 html var 情況 type script
jquery 的擷取與設定說完了，再來探究一下純 js 的設定，是否也會出現此類情況，就知道大致是什麼出現的問題了：
<!DOCTYPE html><html> <head> <meta charset=‘utf-8‘> <style> #d1 { position: absolute; } </style> </head> <body> <div id=‘d1‘></div> <script> var leftV = 961.5799713134766; console.log(‘set value : ‘, leftV); var div = document.getElementById(‘d1‘); console.log(‘target ele : ‘, div); div.setAttribute(‘left‘, leftV); console.log(‘get value : ‘, div.getAttribute(‘left‘)); </script> </body></html>
結果，純 js 設定擷取，值沒問題完全一樣。
結論：jquery 的問題。
