RubyMine 3.1 中的 Highcharts 实现
我想在 ruby on Rails 中实现 highcharts。但是rails.js存在一些运行时问题
错误：Event.Handler.Prototype为null或不是rails.js中的对象
这是控制器：
class LineChartController < ApplicationController
def index
chart_data = [{
:name => 'Expense',
:data => [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
:name => 'Savings',
:data => [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]
tooltip_formatter = '
function() {return "<b>"+ this.series.name +"</b><br/>"+this.x +":"+ this.y +"\u00B0C";}'
@chart = Highchart.new({
:chart => {
:renderTo => "container",
:marginRight => 130,
:marginBottom => 25,
#:defaultSeriesType=> "line"
},
:title => {
:text => "Monthly Average Expenses",
:x => -20
},
:subtitle => {
:text => 'Source: Sample Application',
:x => -20
},
:x_axis => {
:categories => ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
:y_axis => {
:title => {
:text => "Rs. (in 1000's)"
},
:plotLines => [{
:value => 0,
:width => 1,
:color => '#808080'
}]
},
:tooltip => {
:formatter => tooltip_formatter
},
:legend => {
:layout=> 'vertical',
:align=> 'right',
:verticalAlign=> 'top',
:x=> -10,
:y=> 100,
:borderWidth=> 0
},
:series => chart_data
})
end
end
application.html
<head>
<title>Graphs</title>
<%= stylesheet_link_tag :all %>
<%= javascript_include_tag "http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js", "highcharts" %>
<%= csrf_meta_tag %>
</head>
<body>
<%= yield %>
<script type="text/javascript">
$(document).ready(function() {
<%= @chart %>
<%= yield :javascript %>
});
</script>
</body>
问：我哪里出错了？有什么建议吗？
I want to implement highcharts in ruby on rails. But there's some runtime problem with rails.js
Error : Event.Handler.Prototype is null or not an object in rails.js
Here is the Controller :
class LineChartController < ApplicationController
def index
chart_data = [{
:name => 'Expense',
:data => [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
:name => 'Savings',
:data => [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]
tooltip_formatter = '
function() {return "<b>"+ this.series.name +"</b><br/>"+this.x +":"+ this.y +"\u00B0C";}'
@chart = Highchart.new({
:chart => {
:renderTo => "container",
:marginRight => 130,
:marginBottom => 25,
#:defaultSeriesType=> "line"
},
:title => {
:text => "Monthly Average Expenses",
:x => -20
},
:subtitle => {
:text => 'Source: Sample Application',
:x => -20
},
:x_axis => {
:categories => ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
:y_axis => {
:title => {
:text => "Rs. (in 1000's)"
},
:plotLines => [{
:value => 0,
:width => 1,
:color => '#808080'
}]
},
:tooltip => {
:formatter => tooltip_formatter
},
:legend => {
:layout=> 'vertical',
:align=> 'right',
:verticalAlign=> 'top',
:x=> -10,
:y=> 100,
:borderWidth=> 0
},
:series => chart_data
})
end
end
application.html
<head>
<title>Graphs</title>
<%= stylesheet_link_tag :all %>
<%= javascript_include_tag "http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js", "highcharts" %>

<body>
<%= yield %>
<script type="text/javascript">

你必须使用 rails.js for jQuery (rails.js。你使用的默认兼容与原型。
