In wordpress, why I should register and enqueue js scripts with wp_register_script() and wp_enqueue_script()?

Question

为什么不在HTML内容中添加我需要的脚本？

Answer 1

Here are few reasons for WHY!

• First of all, it makes you AWESOME among your friends
• It helps define the dependencies of the script you are using, like won't need to enqueue other scripts like jquery, jquery-ui, thickbox or any other scripts if you have already registered one.
• It makes your code more semantic, and your code will make more sense.
• Your theme or plugin will have less chance of conflicting with other's (like double loading jquery files, fancybox files and so on)
• You will have more control where you want the js to embed on pages with simple conditional tags like

if(is_page() || is_single()){ wp_enqueue_script(......); }

Answer 2

因为插件也需要一种添加脚本的方法。
