isNaN(parseFloat(value))&&isFinite(value); 这其实是jquery中$.isNumeric的源码,多么简洁且优雅。 接下来我们看看它的原理,我们以字符串123abc为例,我们应该得到false。 parseFloat('123abc')得到123; !isNaN(123)得到true; isFinite('123abc')得到false; 最终结果为false。 单独使用!isNaN(parseFloat(value))...

函数是 JavaScript 中的基本组件之一。JavaScript 中的函数类似于过程——一组执行任务或计算值的语句。但要成为函数,这个过程应该接受输入并返回与输入存在某些明显关系的输出。要使用一个函数,你必须将其定义在你希望调用它的作用域内。
Visual variables define the parameters for data-driven visualizations of numeric data. They allow you to easily map continuous ramps of color, size, and opacity to minimum and maximum data values from one of the layer's numeric attribute fields. When used in a UniqueValueRenderer, the unique ...
