jquery-easyui分页组件的用法

项目进行到迭代二的开发和测试阶段,发现一个比较隐藏的bug,那就是分页组件的使用不当问题。

问题现象:

多页面新增数据后,点击下一页数据显示没有问题,但是当前页,总页数的计算出了问题。

原因分析:

show data后,没有重新加载分页控件导致,因为totalRecords是重新计算出来的。

解决方案及代码:

show data后重新加载分页控件。代码如下:

1,页面初始化

1 $(document).ready(function(){ 
2 //初始化分页组件
3     var total=${total};
4     if(total == "0"){
5         var loadingMeg = "<tr class='support_white'><td colspan='12' height='20' align='center'><bean:message key='supportrecover.webduty.nodata'/></td></tr>";
6         $("#dataTbody").html(loadingMeg);
7     }
8     ajaxPagination(total); 
9 });

2,加载分页组件核心函数

 1 function ajaxPagination(totalRecords){
 2     $("#ajaxPagination").pagination({
 3         total: totalRecords,    // totalRecord(总记录数) 需要在进入页面时,在action中赋值
 4         onSelectPage: function(pageNumber, pageSize){
 5             //分页组件显示加载数据状态
 6             $(this).pagination('loading');
 7             //url为请求路径,注意需要带 pageNumber、ajaxPageSize参数。如果有查询参数,拼接上。
 8             var form = document.queryForm;
 9             form.current_page.value = pageNumber;
10             form.page_size.value = pageSize;
11             var regionSelects = $("#q_region2").val();
12             var regSelects = $("#q_reg2").val();
13             var roles = $("#q_role2").val();
14             var gtacs = $("#q_gtac2").val();
15             var dutyDateStarts = $("#q_dutyDateStart2").val();
16             var dutyDateEnds = $("#q_dutyDateEnd2").val();
17             var productLines = $("#q_productLine2").val();
18             var productFamilys = $("#q_productFamily2").val();
19             var products = $("#q_productID2").val();
20             //地区部为空的时候,把代表处也至空
21             if(regSelects == "null" || regSelects == null)
22             {
23                  regSelects = "";
24             }
25             //产品线为空的时候,把产品族也至空
26             if(productFamilys == "null" || productFamilys == null)
27             {
28                  productFamilys = "";
29             }
30             //地区部为空的时候,把代表处也至空
31             if(productFamilys == "")
32             {
33                   products = "";
34                   $("#q_cheakProducts").html("");
35             }
36               //判断日期控件
37             var q_isSuss = q_vilidate();
38             if(!q_isSuss)
39             {
40                 return;
41             }
42             var loadingMeg = "<tr class='support_white'><td colspan='12'><img width='12' height='12' src='<%=request.getContextPath() %>/images/loading.gif'>loading...</td></tr>";
43             //清空表格tbody内容
44             $("#dataTbody").empty();
45             //表格显示加载数据状态
46             $("#dataTbody").html(loadingMeg);
47             $.ajax({
48                 url : "/SupportRecover/pages/webduty/webDuty.do?actionFlag=ajaxGetWebDuty_all",
49                 data:
50                 {    
51                     "regionSelect":regionSelects,
52                     "regSelect":regSelects,
53                     "role":roles,
54                     "dutyDateStart":dutyDateStarts,
55                     "dutyDateEnd":dutyDateEnds,
56                     "productLine":productLines,
57                     "productFamily":productFamilys,
58                     "product":products,
59                     "gtac":gtacs,
60                     "current_page":pageNumber,
61                     "page_size":pageSize
62             },
63             type : "POST",
64             dataType : 'json',
65                 success: function(data) {
66                      showJsonData(data);
67                 },
68                 error:function()
69                 {
70                      forwardToLogin();
71                 }
72             });
73             $("#ajaxPagination").pagination('loaded');
74         }
75     });    
76 }

3,数据展现后重新加载分页控件

 1 function showJsonData(data){
 2     var totalRecords = 0;
 3     var dataStr = "";
 4     if(data != null && data != ""){
 5         var list = data.pageWebDuty.webDutyList;
 6            var jsonLst = eval('(' + list + ')');
 7            totalRecords=eval(data.pageWebDuty.totalRecords);
 8         //alert(jsonLst.length);
 9         if(jsonLst != "" && jsonLst != "undefined"){
10             for(var i=0;i<jsonLst.length;i++){
11                 var commonName=jsonLst[i].commonName;
12                 var dutyRoleName=jsonLst[i].dutyRoleName;
13                 var gtacName=jsonLst[i].gtacName;
14                 
15                 var regionName ="";
16                 var repName ="";
17                 if(nls == "zh")
18                 {
19                     regionName = jsonLst[i].regionNameCn;
20                     repName = jsonLst[i].repNameCn;
21                 }else{
22                     regionName = jsonLst[i].regionNameEn;
23                     repName = jsonLst[i].repNameEn;
24                 }
25                 
26                 var zonedescription=jsonLst[i].zonedescription;
27                 var dutyDateStart=jsonLst[i].dutyDateStart;
28                 var dutyDateEnd=jsonLst[i].dutyDateEnd;
29                 var dutyTimeStart=jsonLst[i].dutyTimeStart;
30                 var dutyTimeEnd=jsonLst[i].dutyTimeEnd;
31                 
32                 var productLineName = "";
33                 var productFamilyName = "";
34                 var productName = "";
35                 if(nls == "zh")
36                 {
37                     productLineName = jsonLst[i].productLineNameCn;
38                     productFamilyName = jsonLst[i].productFamilyNameCn;
39                     productName = jsonLst[i].productNameCn;
40                 }else{
41                     productLineName = jsonLst[i].productLineNameEn;
42                     productFamilyName = jsonLst[i].productFamilyNameEn;
43                     productName = jsonLst[i].productNameEn;
44                 }
45                 
46                 var webDutyId = jsonLst[i].webDutyId;
47                 dataStr = dataStr 
48                 +"<tr id='"+webDutyId+"'>"
49                 +                "<td class='spt_td_ellipsis' title='"+commonName+"'>"+commonName+" </td>"
50                 +                "<td class='spt_td_ellipsis' title='"+dutyRoleName+"'>"+dutyRoleName+"</td>"
51                 //+                "<td class='spt_td_ellipsis' title='"+gtacName+"'>"+gtacName+"</td>"
52                 +                "<td class='spt_td_ellipsis' title='"+regionName+"'>"+regionName+"</td>"
53                 +                "<td class='spt_td_ellipsis' title='"+repName+"'>"+repName+"</td>"
54                 +                "<td class='spt_td_ellipsis' align='right' title='"+dutyDateStart+"'>"+dutyDateStart+"</td>"
55                 +                "<td class='spt_td_ellipsis' align='right' title='"+dutyTimeStart+"'>"+dutyTimeStart+"</td>"
56                 +                "<td class='spt_td_ellipsis' align='right' title='"+dutyDateEnd+"'> "+dutyDateEnd+"</td>"
57                 +                "<td class='spt_td_ellipsis' align='right' title='"+dutyTimeEnd+"'>"+dutyTimeEnd+"</td>"
58                 +                "<td class='spt_td_ellipsis' title='"+productLineName+"'>"+productLineName+"</td>"
59                 +                "<td class='spt_td_ellipsis' title='"+productFamilyName+"'>"+productFamilyName+"</td>"
60                 +                "<td class='spt_td_ellipsis' title='"+productName+"'>"+productName+"</td>"
61                 +                "<td align='center'>"
62                 +                "<span style='cursor:pointer;' onClick='showWebDuty01("+'"'+webDutyId +'"'+");'><img src='<%=request.getContextPath() %>/images/View_file_icon.png' class='spt_webSchedule_img' title='<bean:message key='supportrecover.webduty.queryimg'/>'/></span>&nbsp;&nbsp;"
63                 +                "</td>"
64                 +"</tr>";            
65             }
66         }
67     }
68     
69     if(totalRecords == 0){
70         dataStr = "<tr class='support_white'><td colspan='12' height='20' align='center'><bean:message key='supportrecover.webduty.nodata'/></td></tr>";
71     }
72        $("#dataTbody").html(dataStr);
73        //解决firefox对字符过长...的兼容性问题
74       ffTextOverflow($("#spt_webSchedule_div_result .spt_td_ellipsis"));
75       ajaxPagination(totalRecords);
76 }

 

总结:pageNumber,pageSize是分页组件根据totalRecords自动计算出来的,不需自己计算。
