putting JSON into Google Charts

Question

I'm trying to build a Google chart.

Current, I'm building an array using PHP's json_encode($array) . So,, my array variable looks like this:

var array = [{"name":"John Doe","userId":"12","count":"31"},{"name":"Catherine Cookson","userId":"212","count":"12"},{"name":"Lady Gaga","userId":"61","count":"20"}];

I'm passing it into a function which builds the chart:

drawRetChart(array);

Which then uses the data array: data.addRows(array);

However, when I try to load the chart, I get an error: Error: Every row given must be either null or an array.

How do I resolve this?

Answer 1

您有大量的对象，您需要的是大量的数组。

var array = [[(key,val), (key,val), (key,val)],[array2], [array3]];
