我很难在编辑表单中设置选择框的值。例如,我有这样的 colModel 设置。
colModel:[
{name:'communication_id', key: true, index:'communication_id', width:30},
{name:'communication_type_id', index:'communication_type_id', width:30},
{name:'communication_type_select',index:'communication_type_select',hidden:true,width:150, editable:true,edittype:'select',formatter:'select',editrules: {edithidden:true},
formoptions:{label:'Communication Type'},
editoptions:{dataUrl:"working_data_url",
buildSelect: function(json){
var response = $.parseJSON(json);
var s = '<select>';
$.each(response.results,function(i,com){
s += ('<option value="' + com.communication_type_id + '">'+ com.communication_type_desc + '</option>');
});
return s + "</select>";
},dataInit: function(elem){
alert(temp);
//alert($('#com_table_communication_type_id').val());
//$(elem).val($('#com_table_communication_type_id').val());
}}},
{name:'communication_send_dt', index:'communication_send_dt', width:150, sortable:true, sorttype: 'date',
firstsortorder: 'desc', datefmt:'m/d/Y', editable:true},
editoptions: {recreateForm:true},
rowNum:10,
width:'100%',
rowList:[10,20,30],
pager: '#com_pager',
sortname: 'communication_send_dt',
viewrecords: true,
sortorder: "desc",
loadonce:true,
caption: "Communication",
jsonReader: {
repeatitems : false,
root: "results"
},
height: '100%',
onSelectRow: function(communication_id){
var comtype = $(this).getRowData(communication_id);
var temp = comtype['communication_type_id'];
}
});
grid.jqGrid('navGrid','#com_pager',{edit:true,add:false,del:false});
当我单击编辑按钮时,它会正确加载选择选项,但我在选择哪个选项时遇到问题。我希望将communication_type_id 中的值加载到communication_type_select 中,并且我尝试了不同的方法来实现这一点。基本上,如果communication_type_id 中的id 为2,那么我希望编辑表单中的选择框在加载编辑表单时也设置为2。对此有什么帮助吗?
更新 1:我现在主要通过使用 beforeShowForm 来工作,但现在我遇到了一件奇怪的事情。当我在 beforeShowForm 中有警报时,一切正常,但是当它被注释掉时,它就不起作用了!感谢您的帮助@Oleg!
grid.jqGrid('navGrid','#com_pager',{edit:true,add:false,del:false},
{closeOnEscape:true, recreateForm:true,beforeShowForm: function(formid){
//alert("com type id = "+comidvar + " response id = "+comrespvar + " com form type id = "+comfrmtypevar);
$("#communication_type_select", formid).attr("value",comidvar);
$("#form_response_select", formid).attr("value",comrespvar);
$("#form_type_select", formid).attr("value", comfrmtypevar);
}},
