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。

v-if="dataValue.orderStatus === 'WAIT' || 'CANCEL' || 'CLOSED'"这种写法错误，请帮我修改

这种写法在 Vue.js 中使用 v-if 指令检查条件时存在语法错误。它试图同时比较三个字符串 'WAIT'、'CANCEL' 和 'CLOSED'，应该将它们分开，每个作为独立的条件。正确的写法应该是：
<v-if="dataValue.orderStatus === 'WAIT' || dataValue.orderStatus === 'CANCEL' || dataValue.orderStatus === 'CLOSED'">
<!-- 这里是当 orderStatus 为 WAIT/CANCEL/CLOSED 时显示的内容 -->
</v-if>

这样，v-if 会分别检查每个字符串是否等于 dataValue.orderStatus，只要有一个匹配，表达式就会为真。

else if ((Order_leg2_close.OrderStatus == MAN_TAOJIN_OST_Canceled) || (strcmp(Order_leg2_close.OrderRef, "") == 0) || (Order_leg2_close.OrderSubmitStatus == MAN_TAOJIN_OSS_CancelRejected))

这是一个条件判断语句，其中包含三个条件：

Order_leg2_close.OrderStatus == MAN_TAOJIN_OST_Canceled：判断变量Order_leg2_close中的OrderStatus是否等于MAN_TAOJIN_OST_Canceled，如果是，则条件成立。

strcmp(Order_leg2_close.OrderRef, "") == 0：判断变量Order_leg2_close中的OrderRef是否为空字符串，如果是，则条件成立。

Order_leg2_close.OrderSubmitStatus == MAN_TAOJIN_OSS_CancelRejected：判断变量Order_leg2_close中的OrderSubmitStatus是否等于MAN_TAOJIN_OSS_CancelRejected，如果是，则条件成立。

只要三个条件中有一个成立，整个条件判断语句就成立。当整个条件判断语句成立时，会执行其后面的代码块。
