您可以尝试这样的事情：

$scope.search = function(typeContrat, ville, competence){
      $state.go('app.jobsList',{typeContrat:typeContrat,ville:ville,competence:competence});
    };

我不明白你的问题，

你可以在css中创建一个名为中心的类：

.centered {
position: absolute;
left: 50%;
margin-left: -100px;
}
在CSS文件中你必须放一个。在班级名称之前

然后在你想要居中的标签下的html文件中添加该类，例如在想要居中的图像内部或文本

你想要居中，你可以通过参考你做的那个课

< p class = centered>

或者您可以使用想要居中的段落周围的中心标记

<center> <p> paragraph <p> <center>
