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);
    });

```
