如何在 javascript 的数组中放置特殊字符

Question

In php I can do this to place a back slash inside an array

$symbols = array(".","\\\\");

What is the best method of doing this in javascript with backslash, colon, and semicolon?

Answer 1

Use an array literal delimited by square brackets:

 var symbols = [".","\\", ":", ";"]; console.log(symbols);

See here for a more thorough explanation of arrays and their methods.

Answer 2

you need to scape backslash (backslash is the escape keyword). If you need to push an item to the array use the push() method.

 let arr = ['\\', ':']; arr.push(';'); console.log(arr); //Outputs ["\", ":", ";"]
