(function() { var adpos = document.createElement('div');adpos.id = 'sp57r1vzmca9' ;adpos.style.width = '100%';adpos.style.padding = '0 0px';adpos.style.maxWidth = '640px'; adpos.style.textAlign = 'center';document.currentScript.parentNode.insertBefore(adpos, document.currentScript.nextSibling); 這里面的寬度和邊距需要不斷修改，如何在PHP內(nèi)提交表單把寬度值和對齊值輸入進去，直接生成類似的源碼呢？
