HTML5特殊符号怎么显示

在HTML5中,特殊符号可以通过“字符实体”来显示。HTML中一些特殊符号是无法直接使用显示的,例如“<”和“>”,浏览器会误认为它们是标签;此时就可以使用字符实体“<”和“>”来显示它们。

HTML5特殊符号怎么显示

本教程操作环境:windows7系统、HTML5版、Dell G3电脑。

在 HTML 中,某些字符是预留的。

在 HTML 中不能使用小于号(<)和大于号(>),这是因为浏览器会误认为它们是标签。

如下面的html代码:

   <body>
        显示:<input id="myTest" type="text" value="5<=6" ></input>
    </body>

上面的value属性值中含有“<”,浏览器可能会正常显示,但是在解析的时候可能就会出错。

如果希望正确地显示预留字符,我们必须在 HTML 源代码中使用字符实体(character entities)。 字符实体类似这样:

&entity_name;
或
&#entity_number;

如需显示小于号,我们必须这样写:&lt; 或 &#60; 或 &#060;

提示: 使用实体名而不是数字的好处是,名称易于记忆。不过坏处是,浏览器也许并不支持所有实体名称(对实体数字的支持却很好)。
