[网页设计]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:


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("&","&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;  }  //逆  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 /
