Hi,
I have been trying to return the ‘href’ value from click event. Below is my code snippet:
import dash
import dash_html_components as html
from dash.dependencies import Input, Output, State
app = dash.Dash(
__name__,
meta_tags=[{"name": "viewport", "content": "width=device-width, initial-scale=1"}],
)
def make_table(df, val):
table = []
for index, row in df.iterrows():
rows = []
html.Td([
html.Div([row["col1"]]),
html.A(id = 'link',href=row["file-link"], children=row["link-name"], target="_blank"),
])
table.append(html.Tr(rows))
return table
app.layout = html.Div([
html.Table(
id="table-element",
className="table__container",
)
],
className="six columns",
),
@app.callback(
Output("link", 'pathname'),
[Input('link', 'n_clicks')],
[State('link', 'href')]
)
def open_link(n_clicks, href):
enable_open_link(href) #enable_open_link function takes in the href string value and opens it up in a new window.
@app.callback(
Output("table-element", 'children'),
[Input("input-1-submit", 'n_submit')],
[State('input-1-submit', 'value')]
)
def update_output(ns1,val):
table = make_table(df,val)
return table
The code works upto some extent i.e. it does returns a href value, but not the one I click. Always seem to be returning the last href value stored inside the html table.
Is there a way to fetch the href value when I click on the link?
I know I can use Jquery to fetch the correct href value… but I didn’t find a way to integrate javascript within the call-back function.
