如何将 json 数组元素添加到另一个 json 数组的开头？
How do I add json array element to the beginning of another json array?
所以，我有 json 个数组：
var preferencecolModel={name:'all',index:'all', width:40, align:"left",resizable:false,sortable:false,editable:true};
我需要将其添加到另一个 json 数组的开头。
这就是我想要做的：
$.merge(preferencecolModel,(data[0].PREFERENCESMODEL));
preferenceColModel = $.parseJSON(preferencecolModel);
我很安静显然是错误的。
data[0].PREFERENCESMODEL 来自数据库，看起来像这样：

结果必须是 JSON 数组的形式，而不是字符串，因为它是 jqGrid 的 colModel。
如果你有一个数组，例如data[0].PREFERENCESMODEL，你想在数组的开头插入另一个项目preferencecolModel，那么你可以使用unshift方法：
data[0].PREFERENCESMODEL.unshift(preferencecolModel);
我在 colModel 项中没有看到任何 label 属性。因此，您可能有 另一个包含 colNames 项的数组 ，例如 data[0].PREFERENCESCOLUMNNAMES。 jqGrid 要求数组 colModel 和 colNames 具有相同的长度。因此，您也必须在 colNames 中插入一项。比如空字符串，插入的列
的第header列会显示
data[0].PREFERENCESCOLUMNNAMES.unshift("");
