問題：
我是打算使用上面的語句把數(shù)據(jù)庫的連接字符串寫入上一級網(wǎng)頁的connstr文本框中，但是在執(zhí)行時ie總報告“缺少十六進(jìn)制數(shù)字”。
代碼如下：
a="Provider=Microsoft.Jet.OLEDB.4.0; Data Source=E:\網(wǎng)站設(shè)計\dianming\upload\student.mdb;"
Response.Write("<script>")
html="parent.document.getElementById(""connstr"").value="""+a+""""
Response.Write(html+";")
Response.Write("</script>")
問題分析：
到底是怎么回事呢？經(jīng)過試驗(yàn)發(fā)現(xiàn)，問題出在字符串a(chǎn)中的 “\” 上， 原來javascript中“\”是個特殊的字符，在很多場合需要轉(zhuǎn)換，為此我使用“/“臨時替代”\“一下，在使用到此字符串的時候再轉(zhuǎn)換回來就可以了。
代碼改寫如下：
a="Provider=Microsoft.Jet.OLEDB.4.0; Data Source=E:\網(wǎng)站設(shè)計\dianming\upload\student.mdb;"
html=html+replace(a,"\","/")+""""
Response.Write("<script>")
html="parent.document.getElementById(""connstr"").value="""+a+""""
Response.Write(html+";")
Response.Write("</script>")
