???特點(diǎn):
???1.實(shí)現(xiàn)表格的自助排序,適用范圍很大的,比如生成一張數(shù)據(jù)表,用這個(gè)可以讓用戶按自己的方式進(jìn)行排序,由于是本地JS,所以可以節(jié)省連接資源;
???2.網(wǎng)絡(luò)上此類例子也比較多,但是很多并沒有考慮到"排序規(guī)則"的問題,很多時(shí)候JS使用的是字符排序;
??????從例子中可以看出,在應(yīng)用中對(duì)于字符類型與數(shù)據(jù)類型的排序應(yīng)該使用不同的排序規(guī)則
???說明:
??????表單里面放了一個(gè)"參數(shù)顯示",配合HTML源碼,比較容易理解一些;
??????放在這里,是為了以后工作中好用,因此第2個(gè)表實(shí)現(xiàn)了滾動(dòng)表的效果,隨便把時(shí)間也放上去了,嘻
