创建许多相同类型的JavaScript对象?
创建单个对象比创建相同类型的多个对象要容易得多。为了克服这一障碍,javascript提供了对象构造函数。使用此函数,首先,我们必须创建对象的类型,然后,我们需要声明对象的属性 。
示例
在下面的示例中,最初,我们声明了包含“名称”,“属性”,“年龄”和“名称”的对象类型。后来,使用该类型,我们创建了两个对象,并根据需要在输出中显示了相应的属性。
<html> <body> <p id = "prop"></p> <script> function Business(name, property, age, designation) { this.Name = name; this.prop = property; this.age = age; this.designation = designation; } var person1 = new Business("Trump", "$28.8b", "73", "President"); var person2 = new Business("Jackma", "$35.6b", "54", "entrepeneur"); document.write( "My inpiration is " + person1.Name + " and i want to be an " + person2.designation + "."); </script> </body> </html>
输出结果
My inpiration is Trump and i want to be an entrepeneur.
