从views.py获取Django Python数据到template.html中的javascript对象

Question

I'm using Django's render_to_response to write data out to an html page, but I'd also like that render_ to _response call to load a python dictionary into a javascript associative array. What's the best way to do this?

Answer 1

Convert it to JSON and include, in your template.html, inside a <script> tag, something like

var my_associative_array = {{ json_data }}

after having JSON-encoded your Python dict into a string and put it in the context using key json_data .

Vinay Sajip已经关闭，但是您添加了安全过滤器，以避免django自动转义json数据，因此这可以工作（还有其他方法可以停止自动转义，但这是最简单的方法）：

 var my_associative_array = {{ json_data|safe }}

Answer 3

What does that mean exactly? If you mean you think data in the template is in JavaScript terms, it isn't: You can use python objects in the template directly. If you mean, how do I embed a JSON literal from a Python dictionary or list into my template: Encode it with simplejson, which is included with Django.

But, you often don't want to do this for a couple reasons. If you include this dynamic data in the template, you can't cache it as easily. Shouldn't this be another view that is generating a JS file you're including? Or maybe an AJAX call to grab the data once the page is live? Take the pick for what best fits you situation.
