问题：
想使用datagird里嵌入select下拉框，并在提交form表单时获取datagrid选中的每行数据里的每个下拉框选中的值。
解决方案：
其中economicIssuesSelect使用下拉框，重点关注
initEconomicIssues(row)方法。这里的方法需要传递row
javascript
$('#queryPcpTable').datagrid({
title: 'pcp领用查询信息',
width: wd,
url: send_url,
queryParams:params,
striped: true,
pagination: true,
pageNumber: 1,
// 默认初始每页的行数
pageSize: 5,
// 每页行数可选列表
pageList: [5],
nowrap: true,
checkOnSelect: true,
selectOnCheck: true,
columns: [[
{field: 'checkbox', checkbox: true},
{
field: 'consumingNo',
title: '领用单号',
align: 'center',
width: 180,
formatter:function(value,row,index) {
return '<a name="detail_data" href="#" οnclick="javascript:detailRow(this)">'+ value + '</a>';
}
},
{field: 'consumingNumber', title: '领用数量', align: 'center',
width: 120
},
{field: 'consumingAmount', title: '领用金额', align: 'center', width: wd * (1.3 / (col_size + 1))},
{field: 'economicIssuesSelect', title: '领用事项', align: 'center', width: wd * (1.3 / (col_size + 1)),
formatter:function(value,row,index) {
var selectHtml = initEconomicIssues(row);
return selectHtml;
}
},
// { field: 'economicIssuesNo',
// title: '领用事项', align: 'center',
// width: wd * (1.3 / (col_size + 1)),
// editor: {
// type: 'combobox',//下拉框
// options: {
// valueField: 'economicIssuesNo',//对应为表格中的field
// textField: 'economicIssuesDesc',//显示值
// editable: false,
// panelHeight:102,//控制下拉框高度
// data: economicIssuesNoArryData, //json数据
// required: false
// }
// }
// },
{field: 'url', hidden:true }
]],
onClickRow: function (rowIndex, rowData) {
},
onCheck: function (rowIndex, rowData) {
},
onUncheck: function (rowIndex, rowData) {
},
onLoadSuccess:function (data){
// var rows = $(this).datagrid("getRows");
// //使等级显示为下拉框
// for(var index=0;index<rows.length;index++){
// $(this).datagrid("beginEdit", index);
// if($(this).datagrid("getEditor",{index:index,field:"economicIssuesNo"}).target.combobox('getValue') == ''){
// $(this).datagrid("getEditor",{index:index,field:"economicIssuesNo"}).target.combobox('setValue', "空");
// }
// }
}
});其中economicIssuesNoArry是下拉框里list值，可以是写死也可以是动态ajax获取，这里的方法重点是select的id，这个id是拼凑出来的，由上个datagrid里的consumingNo（唯一主键）构成
javascript
//初始化领用单号经济事项
function initEconomicIssues(obj){
if (economicIssuesNoArry.length > 0) {
var html = '<select id="economicIssuesSelect' + obj.consumingNo + '"' + 'class="easyui-combobox" style="width:250px; required="true">';
for (var i = 0; i < economicIssuesNoArry.length; i++) {
html += '<option value="' + economicIssuesNoArry[i].economicIssuesNo + '">' + economicIssuesNoArry[i].description + '</option>'
}
html += "</select>";
return html;
} else {
//支出类别
var issuesCategory = $("#issuesCategory").val();
//支出项目
var issuesClass = $("#issuesClass").val();
//预算中心
var budgetCenter = $('#budgetCenter').val();
//机构代码
var finBranchCode = $('#responsibleFinBranchCode').val();
var html = "";
//查询经济事项
$.ajax({
type: 'post',
// url: '${ctx}economicIssuesTbl/getEconomicIssuesNo.do?businessBook=${businessBook}&billType=${billType}' + '&issuesCategory=' + issuesCategory + '&issuesClass=' + issuesClass,
url: '${ctx}economicIssuesSet/getExpenseEconomicIssues.do?isExpensesApply=Y&businessBook=${businessBook}&billType=13&budgetCenter='
+ budgetCenter + '&issuesCategory=' + issuesCategory
+ '&finBranchCode=' + finBranchCode
+ '&issuesClass=' + issuesClass,
dataType: 'json',
async: false,
success: function (result) {
var resData = result.rows;
for (var i = 0; i < resData.length; i++) {
if (resData[i].description.search("餐饮、茶歇") != -1) {
economicIssuesNoArry.push(resData[i]);
}
if (resData[i].description.search("杂费") != -1) {
economicIssuesNoArry.push(resData[i]);
}
}
html = '<select id="economicIssuesSelect' + obj.consumingNo + '"' + 'class="easyui-combobox" style="width:250px; required="true">';
for (var i = 0; i < economicIssuesNoArry.length; i++) {
html += '<option value="' + economicIssuesNoArry[i].economicIssuesNo + '">' + economicIssuesNoArry[i].description + '</option>'
}
html += "</select>";
}
});
return html;
}
}获取datagird里的下拉框选中的value和text
这里只需获取选中的rows数组然后通过下标获取对应的行数据，最后通过拼凑id值再使用
$("#id option:selected").val();
方法获取select选中的值和value
javascript
var rows = $('#queryPcpTable').datagrid('getSelections');
var num = rows.length;
......
//已选中的领用单增加行
var rowObj = rows[i];
//获取领用事项的Id
var elementText = "#" + "economicIssuesSelect" + rowObj.consumingNo + " option:selected";
//获取领用事项描述
var economicIssuesDesc = $(elementText).text();
//获取领用事项no
var economicIssuesNo = $(elementText).val();
