Google Charts: How to pass a parameter into a callback (JavaScript)?

问题

I have a following code:

google.charts.setOnLoadCallback( drawChart );
function drawChart() { ... }

I need to pass a parameter called chartID into a drawChart() function. How can I do it? Seems google chart doesn't want to get any params :) Any ideas?

回答1:

one way is to add another function...

google.charts.setOnLoadCallback(function () {
  drawChart(chartID);
});

function drawChart(chartID) { ... }
