基本上,我具有从文件夹中选择两个不同随机图像的功能。此刻,我每次使用onClick="window.location.reload()
来运行该函数。
我是否可以在不刷新页面的情况下调用函数onClick
?
谢谢。

理想情况下,也无需使用Ajax。
我只是使用了addEventListener('click'...)
和encapsulated
您的代码。
单击屏幕,图像将随机更改。
要注意:养成在需要的地方添加(
;
)的习惯,Java对冒号不是严格的(除非使用"use strict"
),但它可能导致冒号将来有很多错误。另外,请在'
中的属性中使用逗号("
或HTML
)。阅读W3 Schools撰写的
