此 JSON 数据中有 22 条记录。如何使用 jQuery 将此 JSON 数据分页为每页 5 个？

编辑：

上图是我使用 jQuery 迭代的员工列表的摘要视图。

var jsonObj = JSON.parse(HfJsonValue);
    for (var i = jsonObj.Table.length - 1; i >= 0; i--) {
        var employee = jsonObj.Table[i];
        $('<div class="resultsdiv"><br /><span class="resultName">' + employee.Emp_Name + '</span><span class="resultfields" style="padding-left:100px;">Category&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Desig_Name + '</span><br /><br /><span id="SalaryBasis" class="resultfields">Salary Basis&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.SalaryBasis + '</span><span class="resultfields" style="padding-left:25px;">Salary&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.FixedSalary + '</span><span style="font-size:110%;font-weight:bolder;padding-left:25px;">Address&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Address + '</span></div>').insertAfter('#ResultsDiv');
    }

我有 22 条记录。现在它可能会增长。如何使用 jQuery 分页对 JSON 数据进行分页？

Answer 1

JQuery JSON 分页演示的简单方法https://jsfiddle.net/rijo/0kjow220/

HTML代码

<div style="width:400px">
<table class="paginated">
    <thead>
        <tr>
            <th class="col">Play Id</th>
            <th class="col">Question1</th>  
       </tr>
  </thead>
  <tbody id="myTable">
 </tbody>

</table>
<span id="nextValue">next</span><br><span id="PreeValue">Pre</span>
</div>

脚本代码

 $(document).ready(function(){
      var table =  $('#myTable');
var b = [{"play_id":"1","question1":"135","q1r":"1","question2":"138","q2r":"1","question3":"","q3r":"0","question4":"","q4r":"0","total_point":"6","amount":"1.7","bet_amount":"10","winning_amount":"20","no_of_players":"10"},....]
    var max_size=b.length;
     var sta = 0;
     var elements_per_page = 4;
     var limit = elements_per_page;
     goFun(sta,limit);
     function goFun(sta,limit) {
      for (var i =sta ; i < limit; i++) {

        var $nr = $('<tr><td>A-' + b[i]['play_id'] + '</td><td>B-' + b[i]['question1']  + '</td></tr>');
        table.append($nr);
      }
      }
      $('#nextValue').click(function(){

        var next = limit;
        if(max_size>=next) {
        limit = limit+elements_per_page;
        table.empty();
        console.log(next +' -next- '+limit);
        goFun(next,limit);
        }
      });
      $('#PreeValue').click(function(){
        var pre = limit-(2*elements_per_page);
        if(pre>=0) {
        limit = limit-elements_per_page;
        console.log(pre +' -pre- '+limit);
        table.empty();
        goFun(pre,limit); 
        }
      });

    });

您必须更具体地说明“每页 5 个”的含义。您是否要将这些数据呈现为 HTML“页面”？

如果是这样，您需要将数据分成 5 组并进行渲染..

Answer 3

您可以使用 Array.splice 方法从数组中创建所需大小的组：

// Parse json etc.
var json = [...];
// Fetch the data for a page from the json-result object
var page = 1,
    recPerPage = 5,
    // Use Math.max to ensure that we at least start from record 0
    startRec = Math.max(page - 1, 0) * 5,
    // The end index of Array.splice doesn't have to be within boundaries,
    // But if you want to ensure that it does, then use 
    // Math.min(startRec + recPerPage, json.table.length)
    endRec = startRec + recPerPage
    recordsToShow = json.table.splice(startRec, endRec);

recordsToShow 现在包含要为页面显示的记录数组。重构page = 1 并将其作为参数，对recPerPage = 5 执行相同的操作，您应该可以开始了。您可以使用 jQuery.each 遍历 recordsToShow，并使用某种模板系统从每条记录中创建 HTML 元素。

您还应该向startRec 添加某种检查，以确保起始记录在边界内。如果不是，则显示第 1 页，或向用户显示错误消息。

jQgrid 是一个很棒的 jQuery 插件，用于处理表格和分页，但是它需要非常特定格式的 json

Answer 5

如果jsonObject是JSON对象，那么

jsonObject.Table[0], jsonObject.Table[1], ... jsonObject.Table[4]

将是第一页的对象。您将如何处理这些页面取决于您的应用程序。
