jqGrid翻页获取选中的值

Posted 2020-06-18 断梳

 

1、实现效果: 点击确定所选按钮之后，获取翻页选中的题库表号

 

2、关键代码

 onSelectAll: function (aRowids, status) {

},

 onSelectRow: function (aRowids, status) {

} 

 jQuery("#questionindex_table").jqGrid({
            url: ‘2safety/exam/questionfile/ashx/list.ashx?act=list‘,
            datatype: "json",
            colNames: [‘ID‘, ‘题库表号‘, ‘文件名称‘, ‘发文号‘, ‘发文部门‘, ‘规章编号‘, ‘发文年月‘],
            autoWidth: true,
            rowNum: rowNum,
            rowList: rowList,
            rownumbers: true,
            pager: ‘#pager‘,
            altRows: true,
            shrinkToFit: false,
            viewrecords: true,
            multiselect: true,
            width: 1030,
            height: 350,
            jsonReader: {
                page: "page",
                total: "total",
                repeatitems: false,
                id: "ID"
            }, 
            onSelectAll: function (aRowids, status) {
                for (var index = 0; index < aRowids.length; index++) {
                    var str = $("#questionindex_table").jqGrid(‘getRowData‘, aRowids[index]).QUESTIONFLAG;
                    var str1 = $("#questionindex_table").jqGrid(‘getRowData‘, aRowids[index]);
                    if (status)
                    {
                        if (arr.toString().indexOf(str) <0) {   
                            arr.push(str);
                            arr1.push({ id: str1.ID, QUESTIONFLAG: str1.QUESTIONFLAG })
                        }    
                    }
                    else
                    {
                        for (var i = 0; i < arr.length; i++) {
                            if (arr[i] == str) {
                                arr.splice(i, 1);
                                arr1.splice(i, 1);
                            }
                        }
                    }                    
                }
            },
            onSelectRow: function (aRowids, status) {
                var str = $("#questionindex_table").jqGrid(‘getRowData‘, aRowids).QUESTIONFLAG;
                var str1 = $("#questionindex_table").jqGrid(‘getRowData‘, aRowids);
                if (status) {
                    arr.push(str);
                    arr1.push({ id: str1.ID, QUESTIONFLAG: str1.QUESTIONFLAG })
                }
                else
                {
                    for (var i = 0; i < arr.length; i++)
                    {
                        if(arr[i]==str)
                        {
                            arr.splice(i,1);
                            arr1.splice(i, 1);
                        }
                    }               
                }
             
            },
            colModel: [
                 { name: ‘ID‘, index: ‘ID‘, hidden: true, frozen: true },
                  { name: ‘QUESTIONFLAG‘, index: ‘QUESTIONFLAG‘, width: 80, frozen: true },
                 {
                     name: ‘NAME‘, index: ‘NAME‘, width: 250, frozen: true,
                     formatter: function (value, type, row) {
                         switch (row.ISACTIVE + ‘‘) {
                             case ‘0‘: str = "<span style=\"color:#999999;text-decoration:line-through;\">" + row.NAME + "</span>"; break;
                             case ‘1‘: str = row.NAME; break;
                             default: str = row.NAME; break;
                         }
                         return str;
                     }
                 },

                 { name: ‘REGULATIONS‘, index: ‘REGULATIONS‘, width: 110 },
                 {
                     name: ‘PUBLISHTIME‘, index: ‘PUBLISHTIME‘, width: 80, align: ‘center‘, formatter: function (cellvalue, options, rowObject) {
                         return parent.setAddTime(cellvalue, ‘yyyy-MM-dd‘);
                     }
                 }
            ]
        });

遗留问题：返回上一页之后，之前选中的标识消失

3、知识点

js数组操作：判断数组中是否存在某个字符串 

var arr=[46013,25210,16414];

var str="16414";

if (arr.toString().indexOf(str) <0)

{alert("不存在") }

else

{alert("存在")}

js数组操作：删除数组中某个字符串 

var arr=[46013,25210,16414];

arr.splice(0, 1);

alert(arr);//[25210,16414];
