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("&","&amp;");
        s = s.replace("<","&lt;");
        s = s.replace(">","&gt;");
        s = s.replace("\t","    ");
        s = s.replace("\r\n","\n");
        s = s.replace("\n","<br>");
        s = s.replace("  "," &nbsp;");
        s = s.replace("'","&#39;");
        s = s.replace("\"","&#34;");
        s = s.replace("\\","&#92;");
        return s;
    }
    //
    public static String unHtml(String s){   
        s = s.replace("<br>","\n");
        s = s.replace("&nbsp;"," ");
        s = s.replace("&lt","<");
        s = s.replace("&gt",">");
        s = s.replace("&amp","&");
        return s;
    }

3.js转义用 /
