python - BeautifulSoup search for an element returns [ ] -

-

the page trying work https://www.google.ca/flights/#search;f=yyc;t=cmh;d=2016-05-07;r=2016-05-11;tt=o (or other flight search). "inspect element" option tells me price associated lowest fare has html <div class="mhnsji-d-zb">$260</div>

i trying find correct way identify element in beautifulsoup can put lowest fare variable lowfare. have read bs4 docs , expected either

lowfare = soup.find_all('.mhnsji-d-zb')

or

lowfare = soup.select('.mhnsji-d-zb')

to give me lowest available flight fare on given flight search, return lowfare = [].

i'm beginner, know case of me doing wrong, after reading documentation i'm still lost.

am on right track? found question on site said html might hidden behind javascript in page, i'm new know that, or if applies in situation.

thanks.

asp.net mvc - breakpoint on javascript in CSHTML? -

i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
