Highcharts column Point Click

问题:

Hello I have already asked a question on Highcharts Point Click not working. Further to that what I have found is my click function works in google chrome but not in IE 8. Can you please help me with this? I am not getting any responses on my earlier question hence I am posting this again -

Below is my code -

var columnoptions = {
                chart: {
                    renderTo: 'container',
                    type: 'column'
                },
                title: {
                    text: 'Exposure Details - Column Chart'
                },
                xAxis: {
                    categories: []
                },
                yAxis: {
                    title: {
                        text: 'Exposure'
                    }
                },              
                plotOptions: {  
            series: {
                cursor: 'pointer',
                point: {
                    events: {
                        click: function() {
                            alert ('here');
                        }
                    }
                }
            } 
        },
                series: []
            };   

and below is the function which draws column chart -

function displayColumnChart(){

     columnoptions.series = [];
     columnoptions.xAxis.categories = [];            
      var seriesOptions = {
                    name: 'chart',
                    data: [],                       

                };
     for(index = 0; index < categoryArray.length; index++){

         columnoptions.xAxis.categories.push(categoryArray[index]);

         seriesOptions.data.push(valueArray[index]);        

     }      

     columnoptions.series.push(seriesOptions); 
     chart = new Highcharts.Chart(columnoptions);
   }

Is it because the way I am dynamically creating this chart? Please guide me regarding this. I am getting error - Object doesnt support this property or method. Highcharts.js line 25. Code 0. Char 55. I wish to implement chart drill down. Hence need to get this working. And IE is standard browser in the company. Please help me.

Object doesnt support this property or method

This is the Javascript error generated mostly in IE.

Always check for extra comma,single quote in your code when you encounter such JS error.

I can see such one in your code snippet.

var seriesOptions = {
                    name: 'chart',
                    data: [],                       

                };

This should be

var seriesOptions = {
                        name: 'chart',
                        data: []                       

                    };

Firefox ignores such error but IE does not let you go. :)

I just used latest highcharts files 2.2.5 and that solved it. Works in IE8. And I feel overall performance is also improved..smooth. Thanks. :)
