This example describes how to implement the sprintf function of PHP Based on JS. We will share this with you for your reference. The details are as follows:

The function is as follows:

<Script type = "text/javascript"> function sprintf () {var arg = arguments, str = arg [0] | '', I, n; for (I = 1, n = arg. length; I <n; I ++) {str = str. replace (/% s/, arg [I]);} return str ;}</script>

<Script type = "text/javascript"> var str = "% s bright light in front of the bed, suspected to be % s frost; Raise your head % s bright moon, bow your head % s hometown. ", Var1 =" Ming ", var2 =" ", var3 =" Wang ", var4 =" Si "; str = sprintf (str, var1, var2, var3, var4); </script>
