This article analyzes the difference between js functions and php functions with examples. Share it with everyone for your reference. The specific analysis is as follows:
In PHP syntax, a function is a grammatical structure, not a variable and cannot be assigned a value;
In JS, a function is also a type of variable, and the variable name is function name.
<html> <head> </head> <body> <script type="text/javascript"> function t(){ return 5; } var m = t;//函数名即是变量名。注意,不能写成t(),加括号是表示调用这个函数。 alert(m()); </script> </body> </html>
So, the function can also be declared like this:
t = function(参数){ 函数体; }
