在Angular 2的ng2 -smart-table排序功能是区分大小写的。是否有任何选项可以使排序表数据不区分大小写?

如果你实现这个以确保你在 compareFunction 之后添加一个:只是想扔掉。如下所示...
columns: {
group_name: {
title: 'Groupname',
compareFunction:(direction: any, a: any, b: any) => {
// Converting strings to lowercase
let first = typeof a === 'string' ? a.toLowerCase() : a;
let second = typeof b === 'string' ? b.toLowerCase() : b;
if (first < second) {
return -1 * direction;
}
if (first > second) {
return direction;
}
return 0;
}
}
}

您可以提供自定义排序函数作为 sort() 方法中的第四个参数。
例子:
let COMPARE_INSENSITIVE = (direction: any, a: any, b: any) => {
// Converting strings to lowercase
let first = typeof a === 'string' ? a.toLowerCase() : a;
let second = typeof b === 'string' ? b.toLowerCase() : b;
if (first < second) {
return -1 * direction;
}
if (first > second) {
return direction;
}
return 0;
}
ng2-smart-table使用以下默认 COMPARE 函数:
export class LocalSorter {
protected static COMPARE = (direction: any, a: any, b: any) => {
if (a < b) {
return -1 * direction;
}
if (a > b) {
return direction;
}
return 0;
}
static sort(data: Array<any>, field: string, direction: string, customCompare?: Function): Array<any> {
const dir: number = (direction === 'asc') ? 1 : -1;
const compare: Function = customCompare ? customCompare : this.COMPARE;
return data.sort((a, b) => {
return compare.call(null, dir, a[field], b[field]);
});
}
}
