web前端

​header div固定，content div填充父容器​
​json接口资源​
jQuery iframe高度自适应内容
  $("#content-frame").load(function(){
      var content_height = $(this).contents().find("body").height();
      $(this).height(content_height);
  });
ajax跨域cookie问题
"Access-Control-Allow-Origin":"*"
解决浏览器对前端的拦截
xhrFields: {withCredentials: true},
允许使用cookie
example
```javascript
function loadValidCode(id) {
$.ajax({
    url: "http://110.64.69.66:8081/team/valid_code",
    processData: false,
    xhrFields: {withCredentials: true}
}).always(function (data) {
        console.log('test');
        $(id).attr('src', "data:image/gif;base64," + data);
    }
);
} $('#reg_btn').click(function () { $.ajax({ type: "post", url: "http://110.64.69.66:8081/team/register/", dataType: "json", data: { "mail": $('#r_mail').val(), "pwd": $('#r_pwd').val(), "inv": $('#r_inv').val(), "code": $('#r_code').val() }, xhrFields: {withCredentials: true}, headers: { "Access-Control-Allow-Origin":"*" }
    }).always(function (data) {
        console.log(data);
    });
```
另一方面还需要后端配合，具体查看各种后端的相关配置
