我有什么,我需要什么。这简单。
默认选项(有嵌套属性):
{
sDom: 'frt<"tfoot"lp>',
bInfo: false,
sPaginationType: "full_numbers",
oLanguage: {
sSearch: "",
sLengthMenu: "Show _MENU_",
oPaginate: {
sFirst: "|<<",
sLast: ">>|",
sNext: ">>",
sPrevious: "<<"
}
}
}
实际选项:
{
oLanguage: {
oPaginate: {
sNext: "MODIFIED"
}
}
}
$.extend 的结果:
{
sDom: 'frt<"tfoot"lp>',
bInfo: false,
sPaginationType: "full_numbers",
oLanguage: {
oPaginate: {
sNext: "MODIFIED"
}
}
}
我需要的是使用实际选项正确扩展默认选项并获得以下结果(一个属性已被修改):
{
sDom: 'frt<"tfoot"lp>',
bInfo: false,
sPaginationType: "full_numbers",
oLanguage: {
sSearch: "",
sLengthMenu: "Show _MENU_",
oPaginate: {
sFirst: "|<<",
sLast: ">>|",
sNext: "MODIFIED"
sPrevious: "<<"
}
}
}
问题是 $.extend 函数忽略了嵌套属性并且只操作第一级属性。现在我已经手动 $.extend 每个嵌套属性,但我想这不是一个解决方案。
