在Javascript
中,如何才能循环遍历此数组(?)以检索其数据?
答案 0 :(得分:2)
就像你跟踪任何其他阵列一样。简单地说,构成此数组的对象不是将其属性存储在地图中的属性名称下,而是将其属性存储在数组中的给定索引下。
theJsonObject.rows.forEach( function(row) {
var url = row[0];
var n = row[1];
do stuff with url and n...
});
forEach
可以替换为适合特定情况的任何内容。例如,如果您想将其转换为具有命名属性的常规对象数组:
var withNamedProperties = theJsonObject.rows.map( function(row) {
return {
url:row[0],
n:row[1]
};
});
