按下确定按钮后，表格重置

Question

我试图编写一个简单的页面，在其中按OK按钮，它将获取页面上查询参数的标题和文本。但是，加载后，似乎重置了查询参数并最终获得了相同的数据。

$(document).ready(function() {
	// left / right arrows
	$(document).keydown(function(e) {
	  if (e.keyCode == 39) {
		$(".move:focus")
		  .next()
		  .focus();
	  }
	  if (e.keyCode == 37) {
		$(".move:focus")
		  .prev()
		  .focus();
	  }
	});

	function okClick() {
	  var urlToUse = 'http://localhost:3000/test?qp=' + $("#myQueryParam").val();
	  return $.ajax({
		url: urlToUse,
		type: "GET",
	  });
	}

	okClick().done(function(result) {
	   console.log("Success", result);
		$("#title").text(result.title);
		$("#iText").text(result.text);
		$("#myQueryParam").val(result.myQueryParam);
		console.log('All done');
	}).fail(function(err) {
	   console.log(err);
	   alert("Something went wrong");
	});

	$("#b1").one(okClick);

	$("#b2").click(function(e) {
	  alert("bb");
	  // add to history
	});
	console.log("ready!");
    
}); // end document.ready

 #myProj{
        background-color: green;
        width: 100%;
        color: #333333;
        height: 300px;
        margin: 0 auto;
        overflow: hidden;
        padding: 10px 0;
        align-items: center;
        justify-content: space-around;
        display: flex;
        float: right;
    }
    
    :focus {
            outline: 20px solid red;
    }
        
    button:focus {
            background: pink;
    }

最初，myQueryParam为0，在首次调用后变为1。但是在第二次调用之前再次变为零并获得相同的数据。
