一句话概括:for in是遍历(object)键名,for of是遍历(array)键值——for of 循环用来获取一对键值对中的值,而 for in 获取的是 键名。 for in 循环出的是key(并且key的类型是string),for of 循环出的是value。 for of 是es6引新引入的特性,修复了es5引入的for in 的不足。 for of 不能循环普通的对象...
JS(或Vue中的methods)遍历map console.log(map); for(var key in map){ console.log("属性:" + key + ",值:" + map[key]); }
All sublayers are referenced in the order in which they are drawn in the view (bottom to top). They may be added, removed, or reordered using the Collection methods. Because Sublayer extends Accessor, its properties may be watched. Examples // Only includes the first sublayer from the ma...
visualMap:{show:false,seriesIndex:[0],inRange:{color:["#cdcaf8","#026aa9"],},}, 需要注意的是: 当区域有数据的时候会使用visualMap的颜色覆盖,如果没有数据则会使用series的itemStyle的样式。 默认最小值和最大值会根据数据自动计算,当然我们也可以指定具体的值。

继承的属性也会被迭代:for…in 循环将遍历对象自身及其原型链上可枚举的属性。如果只希望遍历对象自身的属性,可以使用object.hasOwnProperty(key)来过滤继承的属性。 不适用于数组遍历:虽然 for…in 循环可以遍历数组,但它并不是处理数组的最佳选择。由于数组的索引被视为对象的属性,遍历数组时可能会迭代到其他非数值...
