HTML标签属性（后端）

HTML标签属性（由后端控制）

我们需要在HTML标签控制一条属性，该属性的性质来自后端
例如 <input> 标签里的checked标签，通过它控制复选框是否选择
true为选上，false或空是没选。后面尝试用0和1也可以控制
但是前端返回给后端的是off和on

HTML

<div class="">
    <label>
        <input type="checkbox" class="js-switch" th:attr="checked=${authority.authority2}"/> 用电监测
    </label>
</div>

AuthorityController

@RequestMapping("/authorityManagement")
public String authority(HttpServletRequest req){

    AuthorityEntity authority = new AuthorityEntity();

    req.setAttribute("authority", authority);

    return "authorityManagement";
}

AuthorityEntity

//0和1，true和false都可以控制
private int id;
private String authority1 = "true";
private String authority2 = "false"  ;
private int authority3 = 1;
private int authority4 = 0;
private int authority5 = 0;
private int authority6 = 0;
private int authority7  = 0;
