django template array element access

hi: day_records is a array , i want to access element of it.if i replace the point with 0,or 1 , it's right , but when i use point , it can't access the element ,and with no syntax error.

plant.bind("plothover",
       function(event,pos,item){
       if(item){
           removeTooltip();
           var point = item.dataIndex;           
           showTooltip(item.pageX,item.pageY,"{{day_records.point.date}}");
       }else{

       }
       });

so ,how can i access the array element with the point varable ?

Your template code runs completely independently of JavaScript.

The browser runs JavaScript when the page loads, based on whatever raw code your template produced.

Generate a JavaScript array via the template language that your script can use, or use AJAX to request the data from django for a given point.

day_records = new Array();
{% for point in day_records %}
    day_records[{{ forloop.counter0 }}] = '{{ point.date }}';
{% endfor %}

plant.bind("plothover",
       function(event,pos,item){
       if(item){
           removeTooltip();
           var point = item.dataIndex;           
           showTooltip(item.pageX,item.pageY, day_records[point]);
       }else{
           removeTooltip();
       }
       });

I tried various things whn I stumbled upon this issue. I tried the dot it didn't give me what I wanted. I knew it had to be a dot style since django documentation said so.

I had a list variable like this: food = [{'rice':90},{'beans':56},{'peas':144}]

Finally, what worked was: food.0.rice gives me the number I wanted (for rice), food.0.beans gave me what number was for beans.

I went further to experiment food = [ [{'rice':90},{'beans':56}], [{'banana':90},{'groundnuts':56}] ] I could access groundnuts value as food.1.groundnuts since it is the 2nd array element I hope somebody will value this
