Jquery 获取元素值，然后将其设置到图表js中

Question

here is my input field that can add with users (it is repetitive fields), and my chart that created with chart.js

I want to show user input value in chart. user fill the input element.

I want to replace dynamically user input value with chart column after click on a simple button.

here is my code:

 anychart.onDocumentLoad(function() { var chart = anychart.column([ ["Winter", 2], ["Spring", 7], ["Summer", 6], ["Fall", 10] ]); // set chart title chart.title("chart title"); // set chart container and draw chart.container("container").draw(); });

Answer 1

you have to

• use anychart.data.set()
• convert array to object key value using dataSet.mapAs()
• add input event to the input element
• and to update .set(index, [object key name], newValue)

 anychart.onDocumentLoad(function() { var dataSet = anychart.data.set([ ["Winter", 2], ["Spring", 7], ["Summer", 6], ["Fall", 10] ]); var chart = anychart.column(); // set chart title chart.title("chart title"); // set data var column = chart.column(dataSet); var view = dataSet.mapAs({ key: 0, value: 1 }); // set chart container and draw chart.container("container").draw(); // update on input $('.example input').each(function(index, item) { $(item).on('input', function() { console.log(view.get(index, 'key'), item.value) view.set(index, 'value', item.value) }) }) });
