问题描述:

通过EL表达式,后台数据传到前台,引号及后面的数据被截断的问题:

如:

前端页面:

html:

问题解决:

1.一个简单的办法,把 input 写成这样:

<input type="text" name="data"  value=' '>

value 值用单引号试试
2.更好的办法应该是做 HTML 转义,在数据传到前端前就要处理,用 java 里的相关函数:

 mav.addObject("data", toHtml(form.getData()));

 public static String toHtml(String s) {        s = s.replace("&","&");        s = s.replace("<","<");        s = s.replace(">",">");        s = s.replace("\t","    ");        s = s.replace("\r\n","\n");        s = s.replace("\n","<br>");        s = s.replace("  ","  ");        s = s.replace("'","&#39;");        s = s.replace("\"",""");        s = s.replace("\\","&#92;");        return s;    }    //逆    public static String unHtml(String s){           s = s.replace("<br>","\n");        s = s.replace(" "," ");        s = s.replace("&lt","<");        s = s.replace("&gt",">");        s = s.replace("&amp","&");        return s;    }

3.js转义用 /
