A series will never have values leaf node
A series is represented as a {..<property : values>..}
A series will always one drilldown and a drilldown will have one series in itself which goes in repetition
A series will always have a proerty y or a drilldown
A drilldown will have name leaf node,categories branch and either a another series or a data branch
A category branch will always have a name leaf node
A data branch will always have values leaf node
序列永远不会有叶节点值
级数表示为{….}
一个系列总是一个向下钻取，向下钻取本身有一个重复的系列
一个系列总是有一个proerty或一个drilldown
向下展开将具有名称叶节点、类别分支和另一个系列或数据分支
类别分支将始终具有名称叶节点
数据分支将始终具有叶节点的值
提前感谢我想你想要的答案的关键是在jQuery中使用$（this）。这是each（）函数中的自引用元素，因此对于每个元素，$（this）引用该元素 考虑到这一点，您可以执行以下操作：
var thisElement = $(this);
thisElement.find("some other selector").each(function(){
var theOtherSelector = $(this);
theOtherSelector.find("yet another selector").each(function(){
// and so forth...
};
})
但是，如何在循环中将具有“chart data series”元素的变量重新分配给“chart data drilldown series”，以便遍历XML树中的所有“series”。注：我不知道“图表数据深入系列”的深度，但我会从“图表数据系列”开始遍历。深度可以类似于“图表数据深入系列深入系列”，因此首先，您选择的选择器应该更具体，以便您只能选择直接子级。请参阅。然后，您可能需要定义一个函数来执行迭代的递归任务。我将编辑我的帖子作为一个例子谢谢，但是从递归函数返回的stopper case是什么呢？jquery的每一个都会自动为您计数。如果在选择器条件下找不到任何此类子级，则不会执行回调。
var thisElement = $(this);
thisElement.find("some other selector").each(function(){
var theOtherSelector = $(this);
theOtherSelector.find("yet another selector").each(function(){
// and so forth...
};
})
$xml.find("chart data series").each(function(){
var chartDataSeries = $(this);
var seriesDrillDownSearch = function(){
var seriesDrillDownElement = $(this);
// do your processing here ..
seriesDrillDownElement.find("series drilldown").each(seriesDrillDownSearch);
}();
}
