我有一个 jqGrid,其中有几个字段可以动态填充 filterToolbar 中的下拉框。我希望在“添加记录”对话框中显示相同的结果,为产品和环境字段提供下拉选择器而不是文本输入字段。如您所见,我正在尝试在 beforeShowForm 事件中执行此操作。那是合适的地方吗?将值设置为先前定义的 prodValues 和 envValues 变量会很好,但如有必要,我可以再次发出 ajax 请求(我已经尝试过但也失败了)。
照原样,代码仍然会为 Product 和 Environment 字段生成带有文本输入的表单。如何将它们更改为选择器?
$(function () {
var grid = $("#PSGrid");
var prodValues = $.ajax({
url: "jqGridHandler.ashx?oper=pVals",
async: false,
success: function (data) {
}
}).responseText;
var envValues = $.ajax({
url: "jqGridHandler.ashx?oper=eVals",
async: false,
success: function (data) {
}
}).responseText;
var lastsel = -1;
// build the grid
grid.jqGrid({
