我在JS中有点新手并且起草JS代码来解析和创建HighChart选项结构。 XML文件包含以下格式的内容
系列 - ＆GT; DrillDown-＆GT; Data-用＆GT;系列 - ＆GT; DrillDown-＆GT;数据...
最后一个'数据'分支将有'点'节点。下面是我通过Jquery进行的AJAX调用时收到的XML（filename：ex.xml）文件：

现在我正在编写JS代码来解析和设置HighChart选项。目标是将图表选项设置为如下所示：
struct Series{
float y:
struct DrillDown{
char name[SIZE];
char categories[SIZE][SIZE];
struct Data{
struct Series * series;
float points[SIZE];
};
};
};
struct Series seriesOptions;
与XML树结构格式一样。然后将此Series结构设置为HighChart选项：
options.series.push(seriesOptions);
其中options已在JS脚本中定义了数组。
因此，我遍历每个系列的XML树 - >每个数据的每个DrillDown-＆gt;＆gt;如果系列在那里，那么每个数据的每个DrillDown-＆gt;遍历重复的Series-＆gt;＆gt;设置数据点：
$.get('ex.xml', function(xml) {
var $xml = $(xml);
$xml.find('chart categories name').each(function(i, category) {
options.xAxis.categories.push($(category).text());
});
chart.setTitle.push($xml.find('chart name').text());
$xml.find("chart data series").each(function(i, series){
var seriesDownSearch = function(){
var series = $(this);
var seriesOptions = {
y: parseInt(series.find('y').text()),
drilldown : []
}
series.find("drilldown").each(function(i, drilldown){
//set drilldown name leaf,categories branch name leaf and data branch
$(drilldown).find("data").each(function(i, data) {
//set data point and loop if series branch is present
$(data).find("series").each(seriesDownSearch);
});
})
}();
});
});
我的问题是我如何设置和创建评论代码为 // 。请注意，'名称叶，类别分支名称叶和数据分支'必须是'drilldown'元素和'选项' 'data'元素定义在'钻取'。这样就可以在一种结构下访问它们。
