我尝试将data-src设置为动态的，因此在某些情况下，它将从服务dataOneOne获取数据，而其他时间，它将从dataOneTwo获取数据。这里是HTML代码

<div class="dataOne" data-src="dataOneOne"></div>

dataOneOne是一个返回数据的GET服务，但是，我想设置data-src动态。因此在某些情况下，它将调用dataOneTwo。
下面是我在jquery中尝试的代码

$(document).ready(function() {
 if(some circumstance){
   $("div.dataOne").attr("data-src", "dataOneTwo");
   var data = document.getElementByClass("dataOne");
   console.log(data); // the console log shows <div class="dataOne" data-src="dataOneTwo"></div>, but in network, it's still calling the dataOneOne GET service 
   // also tried below option too, 
   $("div.dataOne").data("src", "dataOneTwo"); // both console log and network are showing or using dataOneOne
 }
})
