Question

Here is the page referred to in this question.

我有一个放大器列表，它根据第一个选择从几个JSON文件中提取库存数据。＆＃39;选择您的机器类型＆＃39;拉动all.json，＆＃39;挖掘机＆＃39;拉动EX.json，＆＃39;轮式装载机＆＃39;拉WL.json。

在我的放大器列表中，我使用PHP动态设置我的高度 - 我使用的方法从我每晚使用cronjob创建的文件中提取循环计数变量的最后一个实例。有点不正统，但我在截止日期前，所有长度/数量/大小的方法都没有为我做。

<amp-list width="auto" height="<?php echo file_get_contents('json/count.txt')*70; ?>" [height]="inventory.listSrc.length*70" layout="fixed-height" src="json/all.json" [src]="inventory.listSrc">

当我选择挖掘机时，高度计算正确。当我选择一个make时，高度计算正确。但是，当我选择轮式装载机时，高度无法正确计算。虽然，当我为Wheel Loader选择一个make时，高度按预期计算。

以下是我的两个驱动挖掘机和轮式装载机的JSON文件。

EX.json
