HTML中显示特殊字符,如尖括号 “<”,">"_html/css_WEB-ITnose
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。
在网上搜了一下，如果要在标签中显示"<"或者">"等特殊字符，可以使用“&”开头，“;”结尾，中间加上字符对应的编码就可以啦。
如：
< < <= ≤
> > >= ≥
<body> 小于等于：<input id="myTest1" type="text" value="5≤6" ></input><br> 大于：<input id="myTest2" type="text" value="5>6" ></input><br></body>
