使用自动完成功能输入相互依赖的文本

Question

我创建了 2 个输入文本，一个是 ID，另一个是名称。如果我在第一个输入文本中键入一个 ID，然后按 Tab 或单击第二个输入文本（在 HTML 中使用 onfocusout），第二个输入文本将自动填充分配给该 ID 的名称。例如，输入 ID '001' 将显示 'Elnora'。同样，在第二个输入文本中键入“Soo”（然后按 Tab）将在第一个输入文本中显示“010”。基本上它是基于索引号的一对一映射。正如您在我的Jsfiddle 中看到的那样，这完美无缺。

    var scholaridlists = ["001","002","003","004","005","006","007","008","009","010"];
    var scholarlists = ["Elnora","Henry","Scotty","Bruna","Shirley","Modesto","Lissa","Davida","Margherita","Soo"];

 function idtoname() {
    var ids=document.getElementById("currentscholaridlist").value;
    var a = scholaridlists.indexOf(ids);
    document.getElementById("currentscholarlist").value =scholarlists[a];
}

 function nametoid() {
    var names=document.getElementById('currentscholarlist').value;
    var b = scholarlists.indexOf(names);
    document.getElementById('currentscholaridlist').value = scholaridlists[b];
}

但是，由于不是每个人都记得任何人的 ID 和/或姓名，我还想实现一个自动完成功能，这样每当有人输入 ID/姓名时，就会出现建议的 ID/姓名列表。我正在尝试像在我的其他 Jsfiddle 中一样使用 JQueryUI 自动完成功能。自动完成功能有效，但按 Tab/单击其他输入文本不会显示其他分配的配对。

 $( function() {
     "use strict";

var scholaridlists = ["001","002","003","004","005","006","007","008","009","010"];
$( "#currentscholaridlist" ).autocomplete({      source: scholaridlists, minLength:3, maxShowItems:5    });


   var scholarlists = ["Elnora","Henry","Scotty","Bruna","Shirley","Modesto","Lissa","Davida","Margherita","Soo"];
  $( "#currentscholarlist" ).autocomplete({      source: scholarlists, minLength:3, maxShowItems:5    });

} ); 

 function idtoname() {
    var ids1=document.getElementById("currentscholaridlist").value;
    var a = scholaridlists.indexOf(ids1);
    var ids2= a;
    document.getElementById("currentscholarlist").value =scholarlists[ids2];
}

 function nametoid() {
    var names1=document.getElementById('currentscholarlist').value;
    var b = scholarlists.indexOf(names1);
    var names2 = b;
    document.getElementById('currentscholaridlist').value = scholaridlists[names2];
} 

如果有人对此问题有解决方案，我希望 Ids/names 数组列表保留在 JS 中，而不是使用 select/option 的 HTML 中。此外，ID 不一定是数字和字母/编号顺序，如 Jsfiddle 所示（我可以使用 A123、SC001A 等 ID）。

提前致谢！

Answer 1

这里需要做一些更改。

使用onblur

HTML

<input type="text" id="currentscholaridlist" onblur="idtoname()">
<br/>
<input type="text" id="currentscholarlist" onblur="nametoid(this)">
<br/>

源数组需要在函数之外。这是因为idtoname & nametoid不在$(function(){..})的范围内。所以他们将无法访问数组

JS

   var scholaridlists = ["001", "002", "003", "004", "005", "006", "007", "008", "009", "010"];
   var scholarlists = ["Elnora", "Henry", "Scotty", "Bruna", "Shirley", "Modesto", "Lissa", "Davida", "Margherita", "Soo"];
   $(function() {
      // Rest of the code
   });

   function idtoname() {
     // rest of the code
   }

   function nametoid() {
     // rest of the code
   }
