web前端

  • 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);
});

```
