- Part of the screenshot shows the description, a div to place data, a placement effect. Simulation background, the structure is dynamically displayed according to jquery syntax.
- Some jquery syntax explanations
key is the corresponding dynamic display effect, which can extend attribute values. SKU? List is a combination of existing properties.
There are four specifications of attr1, attr2, attr3 and attr4 (equivalent to color, size, memory and model), among which there are 2x4x2x2 = 48 combinations. In fact, there are only nine combinations sold, which are listed in sku_upulist.
- Some function descriptions
These two functions display data and structure dynamically based on the two arrays in the above figure. keys and SKU list
