Django：如何从views.py获取字典到javascript函数（html文件）

Question

Pretty new to html/ javascript but basically in my views.py, I have a dictionary object created from user form data:

return render(request, 'graph/result.html', {'single_wv': single_wv})

How do I get that context variable into a javascript function (function is inside my html file)?

**Basically I want: index.html form data --> obtained inside views.py with POST --> some manipulation --> dictionary --> dictionary set as context variable --> call inside same index.html javascript function

Sorry if this question is kind of vague, I'm currently in the process of trying to figure everything out!

Answer 1

A common pattern would be to render single_wv somewhere in your graph/result.html like so;

<script>
    window.single_wv = {{ single_wv }};
</script>

Which would make it available to all scripts on your page. More advanced methods of injection depend on what type of front end scripts you have running.

If your value is a complex JSON object, see questions such as Using JSON in django template for more details.
