2023, Week 33, Article 1. Give yourself a goal, and then insist that there will always be a receipt, if you don’t believe me, try it!
WeUI DatePicker, this component is rarely used in pure html static file js, and I forgot how to set the default binding value, so I used chatGPT to find the answer.
It turns out that when chatGPT does not find the correct answer, it will write it by itself according to programming thinking. Corrected several times but it was wrong.

Fourth, bind the default value
4.1, correct binding method
The correct way to bind the default value is to separate the year, month and day.
In fact, WeUI DatePicker can defaultValueset the default value through the property.
- The following is the correct way to write:
weui.datePicker({
defaultValue: [2023, 8, 2], // 设置默认值为 [年, 月, 日]
onChange: function(result) {
console.log(result);
}
});
In this example, we use defaultValuethe attribute to set the default value to [2023, 8, 2], which represents August 2, 2023.
When the user opens the date picker, this date will be displayed by default, and the user can also select other dates.
Note that the range of months is 0-11, so 8 represents September. The value range of date is 1-31.
