how to replace " char to '?

Question

我想用'代替" char。

Answer 1

Use the replace method on the string str you want to replace it in:

str = str.replace(/"/g, "'");

Important is to use a regular expression with the g flag set to replace globally. If you omit that g flag or use a string for the search, you will only replace the first occurrence.

Answer 2

str.replace("\"", "\'")

Answer 3

使用替换方法：

str = str.replace(/"/g, "'"));
