pagination.records = list[0].TotalRows;

这是一个赋值语句,将list[0]中的TotalRows属性值赋给pagination.records。具体来说,pagination是一个分页对象,records属性表示总记录数,而list是一个数据列表,其中list[0]表示第一页的数据。因此,这个语句的作用是将第一页的总记录数赋给分页对象的records属性。至于list和pagination的具体实现,需要根据上下文来确定。

优化这段代码 if (this.form.productType != 1) { this.form.orderStatus = ""; this.form.productName = ""; this.form.orderCode = ""; this.form.saleStartDate = ""; this.form.saleEndDate = ""; this.form.playStartDate = ""; this.form.playEndDate = ""; this.form.sessionCode = ""; this.form.showManagementName = ""; } else { this.form.orderStatus = ""; this.form.productName = ""; this.form.orderCode = ""; this.form.saleStartDate = ""; this.form.saleEndDate = ""; this.form.playStartDate = ""; this.form.playEndDate = ""; // this.sessionList =[]; } console.log(this.form, "form", this.sessionList); this.form.salesTime = "sales"; this.selectUsers = []; this.pagination.pageNum = 1; this.pagination.pageSize = 10
可以使用对象解构来简化代码,同时可以将重复的部分提取出来,避免代码的重复:
```
const clearFields = {
orderStatus: "",
productName: "",
orderCode: "",
saleStartDate: "",
saleEndDate: "",
playStartDate: "",
playEndDate: "",
};
if (this.form.productType != 1) {
this.form = { ...this.form, ...clearFields, sessionCode: "", showManagementName: "" };
} else {
this.form = { ...this.form, ...clearFields, sessionList: [] };
}
console.log(this.form, "form", this.sessionList);
this.form.salesTime = "sales";
this.selectUsers = [];
this.pagination.pageNum = 1;
this.pagination.pageSize = 10;
```
这样可以使代码更简洁,易于维护。同时,使用对象解构还可以避免手动把每个字段赋值为空字符串,这样代码的可读性也会更好。
优化这段代码 switch (this.form.productType) { case 1: data = this.ticketData(); BatchEndorseAPI.ticketList({ ...data, pageSize: this.pagination.pageSize, pageNum: this.pagination.pageNum, }).then((res: any) => { this.loading = false; if (res.code == 200) { this.tbData = res.data.list; this.pagination.totalCount = res.data.total; } else { this.$message.error(res.msg); } }); break; case 3: data = this.theatreData(); BatchEndorseAPI.theatreList({ ...data, pageSize: this.pagination.pageSize, pageNum: this.pagination.pageNum, }).then((res: any) => { this.loading = false; if (res.code == 200) { this.tbData = res.data.list; this.pagination.totalCount = res.data.total; } else { this.$message.error(res.msg); } }); break; default: break; }
可以将两个case合并,提取出共同的部分,减少重复代码。代码如下:
```
let apiFunc, data;
switch (this.form.productType) {
case 1:
apiFunc = BatchEndorseAPI.ticketList;
data = this.ticketData();
break;
case 3:
apiFunc = BatchEndorseAPI.theatreList;
data = this.theatreData();
break;
default:
return;
}
apiFunc({...data, pageSize: this.pagination.pageSize, pageNum: this.pagination.pageNum}).then((res: any) => {
this.loading = false;
if (res.code == 200) {
this.tbData = res.data.list;
this.pagination.totalCount = res.data.total;
} else {
this.$message.error(res.msg);
}
});
```
这样可以使代码更加简洁易读,并且减少了冗余的重复代码。
