html - How to insert a JavaScript variable into Flask url_for() function? -

-

i have following code in flask template:

<div id="cell1"></div> <script> var id="0014"; cell1.innerhtml = '<a href={{url_for('static',filename='+id+'".txt")}}">'+id+'</a>'; </script>

i want link render to:

http://my_address/static/0014.txt

but got this:

http://my_address/static/+id+.txt

how make js variable id in flask url_for() function work?

thanks help!

try this:

cell1.innerhtml = '<a href={{url_for('static', filename='')}}' + id + '.txt>' + id + '</a>';

url_for() generate link this: .../static/<filename>. if use url_for('static', filename=''), generate link like: .../static/, can add text after (i.e. + id + '.txt>') .

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
