KEEPING BEN SHOW
As mentioned in the title, the project has been written and is based on local_storage
The project stored locally
The project runtime is based on brython
, You may want to ask, why not use native python
to write web pages. There is a misunderstanding that web pages are written by html
code, and nativepython
It is very difficult to operate DOM
, so brython
is designed for this purpose.
When you initially open the page, there is only one Add button because there is no data display.
When we click the [Draw a circle and write it down] button, it will refresh to a new page, for example:
At this point, we only need to enter information, such as recording a grudge against our wife. If we reveal the reason for buying a switch game to our mother-in-law, we will be scolded.
At this point, click Hold a Grudge and it will be stored on the page.
If you click Forgiven at this time, you can delete the record.
brython's local_storage
You may have noticed carefully, hey, if you close the browser and open it next time, why is there still a record on it? This is because of the use of local_storage
, so, what is local_storage
?
Hey, we are using local_storage
in brython
, but it is not defined by python
, but HTML 5
is one of the APIs for storing data, which can maintain key-value pair data blocks in the browser.
Now let’s show the storage and deletion operations using brython
.
Import library:
from browser.local_storage import storage
Storage data, such as key value information juejinName
is stored as pdudo
storage[juejinName] = "pdudo"
If you query, directly Just use storage[variable]
, if it is empty, it will return None
v = storage[juejinName]
to loop through all key
, you need to introduce window
library, and then use for...in
to complete
from browser import window for key in window.localStorage: print(key)
, or you can directly use for...in
to traverse storage
What about deleting data? Just delete the dictionary
del storage[juejinName]
storage
Is the operation very similar to the dictionary? Reduces developers’ learning costs.
Production project
After we have the above prerequisites, we can look at the project again and it can be summarized as an addition and deletion check for localStorage
. First, when the page is loaded time, we need to first traverse the localstorage
data to map it to a table
, for example:
for key in window.localStorage: tr = html.TR() datas = json.loads(storage[key]) delBtn = html.BUTTON("已原谅") delBtn.dataset["id"] = datas["id"] delBtn.className = "confirm-btn" delBtn.bind("click",delGrudges) td = html.TD(delBtn+" "+time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(int(datas["id"])))) tr <= td for tdVal in datas["whos"],datas["Text"]: td = html.TD(tdVal) tr <= td tb <= tr userWindows <= tb
The above code traverses localStorage
, and then After defining the delete button, after combining other values, load them all into table
, and then display them on the page.
What about adding data?
def saveGrudges(ev): getWhoVal = document["whos"].value getTextVal = document["textArea"].value if getWhoVal == "" or getTextVal == "": return document["saveBtn"].unbind("click") ids = int(time.time()) datas = { "id": ids, "whos": getWhoVal, "Text": getTextVal } storage[str(ids)] = json.dumps(datas)
The above code displays the values in the input
and textarea
boxes, and then determines whether the user has not input. We assemble the data into a dictionary and then convert it to String, and then store it in localstage
.
There are other operations. You can directly read the code description for this. brython
It's very simple.
