不知道大家注意到了沒(méi)有，Google和Baidu網(wǎng)頁(yè)的HTML源代碼是混合在一起的。HTML代碼混合在一起，出發(fā)點(diǎn)是為了減小網(wǎng)頁(yè)體積，從而加快網(wǎng)頁(yè)加載速度。
寫個(gè)函數(shù)把網(wǎng)頁(yè)HTML源代碼的換行符和空格過(guò)濾掉其實(shí)并不難，我這里是寫了個(gè)基類，在asp.net編程時(shí)，頁(yè)面只要繼承這個(gè)基類，那么輸出的HTML代碼就會(huì)自動(dòng)去掉換行符，和多余的空格符號(hào)，例如“> <”之間的空格符號(hào)。
