each()函数的使用

//异步加载所属项目链接
$('#J_cr_list').find('.cr-href-project-link').each(function(index, ele){
  var $this = $(ele);
  if($this.data('project-id')){
    $.ajax({
      url: '/ec/ajax/project/cr/relate',
      type: 'GET',
      data: {
        projectId: $this.data('project-id')
      },
      success: function (data) {
        if (data && data.successful && data.object
          && data.object.ret && (data.object.ret).length >0 ) {
          var ret = data.object.ret;
          var project = ret[0];
          $this.text(project.name);
        }
      },
      error: function () {
      }
    });
  }
});
