出门在外也不愁HTML字符实体(Character Entities),转义字符串(Escape Sequence)
为什么要用转义字符串?
HTML中&,&,&等有特殊含义(&,&,用于链接签,&用于转义),不能直接使用。这些符号是不显示在我们最终看到的网页里的,那如果我们希望在网页中显示这些符号,该怎么办呢?
这就要说到HTML转义字符串(Escape Sequence)了。
(Escape Sequence)也称字符实体(Character Entity)。在HTML中,定义转义字符串的原因有两个:第一个原因是像“&”和“&gt”这类符号已经用来表示HTML标签,因此就不能直接当作文本中的符号来使用。为了在HTML文档中使用这些符号,就需要定义它的转义字符串。当解释程序遇到这类字符串时就把它解释为真实的字符。在输入转义字符串时,要严格遵守字母大小写的规则。第二个原因是,有些字符在ASCII字符集中没有定义,因此需要使用转义字符串来表示。
转义字符串的组成
转义字符串(Escape Sequence),即字符实体(Character Entity)分成三部分:第一部分是一个&符号,英文叫ampersand;第二部分是实体(Entity)名字或者是#加上实体(Entity)编号;第三部分是一个分号。
比如,要显示小于号(&),就可以写 & 或者 < 。
用实体(Entity)名字的好处是比较好理解,一看lt,大概就猜出是less than的意思,但是其劣势在于并不是所有的浏览器都支持最新的Entity名字。而实体(Entity)编号,各种浏览器都能处理。
提示:实体名称(Entity)是区分大小写的。
备注:同一个符号,可以用“实体名称”和“实体编号”两种方式引用,“实体名称”的优势在于便于记忆,但不能保证所有的浏览器都能顺利识别它,而“实体编号”则没有这种担忧,但它实在不方便记忆。
如何显示空格?
通常情况下,HTML会自动截去多余的空格。不管你加多少空格,都被看做一个空格。比如你在两个字之间加了10个空格,HTML会截去9个空格,只保留一个。为了在网页中增加空格,你可以使用&表示空格。
HTML特殊转义字符列表
最常用的字符实体Character Entities
半方大的空白
全方大的空白
不断行的空白格
已注册商标
商标(美国)
ISO 8859-1 (Latin-1)字符集
HTML 4.01 支持 ISO 8859-1 (Latin-1) 字符集。
备注:为了方便起见,以下表格中,“实体名称”简称为“名称”,“实体编号”简称为“编号”
数学和希腊字母标志symbols, mathematical symbols, and Greek letters
重要的国际标记markup-significant and internationalization characters
JavaScript转义符
横向跳格 (Ctrl-I)
编程的时候要注意特殊字符的问题,很多运行时出现的问题都是因为特殊字符的出现而引起的。
注意,由于反斜杠本身用作转义符,因此不能直接在脚本中键入一个反斜杠。如果要产生一个反斜杠,必须一起键入两个反斜杠 (\\)。
编码转换(to Unicode)
(程序代码来源于网络)
&&&& test = "你好abc"
&&&& str = ""
&&&& for( i=0;&&& i&test. i++ )
temp = test.charCodeAt(i).toString(16);
str&&& += "\\u"+ new Array(5-String(temp).length).join("0") +
&&&& document.write (str)
Function Unicode(str1)
&&&& Dim str,temp
&&&& str = ""
&&&& For i=1&&& to len(str1)
temp = Hex(AscW(Mid(str1,i,1)))
If len(temp) & 5 Then&&& temp = right("0000" & temp, 4)
str = str & "\u" & temp
&&&& Unicode = str
End Function
Function htmlentities(str)
&&&& For i = 1 to Len(str)
&&&&&&&& char = mid(str, i, 1)
&&&&&&&& If Ascw(char) & 128 then
&&&&&&&&&&&& htmlentities = htmlentities & "&#" & Ascw(char) & ";"
&&&&&&&& Else
&&&&&&&&&&&& htmlentities = htmlentities & char
&&&&&&&& End if
End Function
coldfusion版
function nochaoscode(str)
&&&& var new_str = “”;
&&&& for(i=1; i lte len(str);i=i+1){
&&&&&&&& if(asc(mid(str,i,1)) lt 128){
&&&&&&&&&&&& new_str = new_str & mid(str,i,1);
&&&&&&&& }else{
&&&&&&&&&&&& new_str = new_str & “&##” & asc(mid(str,i,1));
&&&&&&&& }
&&&& return new_
在php中我们可以用mbstring的mb_convert_encoding函数实现这个正向及反向的转化。 如:
mb_convert_encoding ("你好", "HTML-ENTITIES", "gb2312"); //输出:你好
mb_convert_encoding ("你好", "gb2312", "HTML-ENTITIES"); //输出:你好
如果需要对整个页面转化,则只需要在php文件的头部加上这三行代码:
mb_internal_encoding("gb2312"); // 这里的gb2312是你网站原来的编码
mb_http_output("HTML-ENTITIES");
ob_start('mb_output_handler');
