我正在使用jqGrid 3.8.1。我想根据另一个组合框的选定值更改组合框的下拉值。这就是为什么我要搜索如何更改editoptions:value的{{1}}。
以下是jqGrid代码示例：
edittype:"select"情景：
<%@ page pageEncoding="UTF-8" contentType="text/html;charset=UTF-8"%>
<script type="text/javascript" src="<c:url value="/js/jquery/grid.locale-ja.js" />" charset="UTF-8"></script>
<link type="text/css" rel="stylesheet" href="<c:url value="/css/jquery/ui.jqgrid.css" />"/>
<script src="<c:url value="/js/jquery/jquery.jqGrid.min.js" />" type="text/javascript"></script>
<table id="rowed5"></table>
<script type="text/javascript" charset="utf-8">
var lastsel2;
$("#rowed5").jqGrid({
datatype: "local",
height: 250,
colNames:['ID Number','Name', 'Stock', 'Ship via','Notes'],
colModel:[
{name:'id',index:'id', width:90, sorttype:"int", editable: true},
{name:'name',index:'name', width:150,editable: true,editoptions:{size:"20",maxlength:"30"}},
{name:'stock',index:'stock', width:60, editable: true,edittype:"checkbox",editoptions: {value:"Yes:No"}},
{name:'ship',index:'ship', width:90, editable: true,edittype:"select",editoptions:{value:"FE:FedEx;IN:InTime;TN:TNT;AR:ARAMEX;AR1:ARAMEX123456789"}},
{name:'note',index:'note', width:200, sortable:false,editable: true,edittype:"textarea", editoptions:{rows:"2",cols:"10"}}
],
caption: "Input Types",
resizeStop: function (newwidth, index) {
var selectedRowId = $("#rowed5").getGridParam('selrow');
if(selectedRowId) {
//resize combobox proportionate to column size
var selectElement = $('[id="' + selectedRowId + '_ship"][role="select"]');
if(selectElement.length > 0){
$(selectElement).width(newwidth);
}
}
}
,
onSelectRow: function(id){
if(id && id!==lastsel2){
//$(this).saveRow(lastsel2, true);
$(this).restoreRow(lastsel2);
$(this).editRow(id,true);
lastsel2=id;
$(this).scroll();
//resize combobox proportionate to column size
var rowSelectElements = $('[id^="' + id + '_"][role="select"]');
if(rowSelectElements.length > 0) {
$(rowSelectElements).each(function(index, element){
var name = $(element).attr('name');
var columnElement = $('#rowed5_' + name);
if(columnElement.length > 0) {
var columnWidth = $(columnElement).width();
$(element).width(columnWidth);
}
});
}
}
}
});
var mydata2 = [
{id:"12345",name:"Desktop Computer",note:"note",stock:"Yes",ship:"FedEx"},
{id:"23456",name:"Laptop",note:"Long text ",stock:"Yes",ship:"InTime"},
{id:"34567",name:"LCD Monitor",note:"note3",stock:"Yes",ship:"TNT"},
{id:"45678",name:"Speakers",note:"note",stock:"No",ship:"ARAMEX123456789"},
{id:"56789",name:"Laser Printer",note:"note2",stock:"Yes",ship:"FedEx"},
{id:"67890",name:"Play Station",note:"note3",stock:"No", ship:"FedEx"},
{id:"76543",name:"Mobile Telephone",note:"note",stock:"Yes",ship:"ARAMEX"},
{id:"87654",name:"Server",note:"note2",stock:"Yes",ship:"TNT"},
{id:"98765",name:"Matrix Printer",note:"note3",stock:"No", ship:"FedEx"}
];
for(var i=0;i < mydata2.length;i++) {
$("#rowed5").jqGrid('addRowData',mydata2[i].id,mydata2[i]);
}
</script>
都将显示为初始加载。ship，则Yes将仅显示ship，FedEx。TNT，则No将仅显示ship，InTime，ARAMEX。如何更改选项？
答案 0 :(得分：5)
我通过反复试验解决了这个问题。想要分享，请参阅以下代码段。 更改在onSelectRow函数。
onSelectRow: function(id){
if(id && id!==lastsel2){
//$(this).saveRow(lastsel2, true);
$(this).restoreRow(lastsel2);
// get the selected stock column value before the editRow
var stockValue = $("#rowed5").jqGrid('getCell', id, 'stock');
if( stockValue == 'Yes') {
$("#rowed5").jqGrid('setColProp', 'ship', { editoptions: { value: 'FE:FedEx;TN:TNT'} });
} else if( stockValue == 'No') {
$("#rowed5").jqGrid('setColProp', 'ship', { editoptions: { value: 'IN:InTime;AR:ARAMEX;AR1:ARAMEX123456789'} });
}
$(this).editRow(id,true);
lastsel2=id;
$(this).scroll();
//resize combobox proportionate to column size
var rowSelectElements = $('[id^="' + id + '_"][role="select"]');
if(rowSelectElements.length > 0) {
$(rowSelectElements).each(function(index, element){
var name = $(element).attr('name');
var columnElement = $('#rowed5_' + name);
if(columnElement.length > 0) {
var columnWidth = $(columnElement).width();
$(element).width(columnWidth);
}
});
}
}
}
