jquery - jqGrid colmodel 在 loadComplete 中的更改

经过 3 个小时的谷歌搜索后,我请求你的帮助。

我的页面上有一个 jqGrid。

网格的重要选项:

$("#listU05").jqGrid({
url:'u05json.json',
datatype: 'json',
mtype: 'POST',

colModel :[
{name:'Thema', index:'Thema', width:55},
....
loadComplete: function(data) {
jQuery("#listU05").jqGrid.setColProp('Thema',
{
stype: 'select',
searchoptions: {
value:"a:a;b:b"
}
}
);

加载数据后,我的网格上有[正在加载...]矩形,并且对代码没有任何反应。我在调试器中看到代码处于事件状态,但在 colModel 中没有任何可见结果,并且有矩形。

问题是什么?

非常感谢您的帮助。

更新:当前使用的代码仍然不起作用

最佳答案

“正在加载...”不消失通常意味着在填充网格或执行某些回调函数(例如loadComplete)期间发生异常。在您的情况下,错误是您使用 jQuery("#listU05").jqGrid.setColProp 而不是 jQuery("#listU05").setColPropjQuery ("#listU05").jqGrid('setColProp', ....

您可以使用loadComplete的代码来

loadComplete: function(data) {
$(this).jqGrid('setColProp', 'Thema', {
stype: 'select',
searchoptions: {
value:"a:a;b:b"
}
});
}

我建议您另外考虑使用 beforeProcessing 进行此类操作。如果设置 colModel 的搜索属性,这并不重要,但如果您想使用 formatter:'select'并从服务器加载 editoptions.value 然后使用 beforeProcessing 是完全正确的地方。从服务器返回的数据尚未处理。因此您可以更改 editoptionsvalue 属性以及在当前数据处理期间 editoptionsvalue 属性将由'select'格式化程序使用。
