jQuery Replace Single or Double Quotes

Replace single or double quotes with jQuery

The following are some simple jQuery code snippets that demonstrate how to replace single and double quotes with jQuery's replace() function. The replace() function has two parameters: the first parameter is to search for all quotes (single or double quotes) globally, and the second parameter is to replace their characters (if you want to replace them with other characters, you can modify the second parameter - this code just removes it).

// 替换所有单引号
var myStr = myStr.replace(/'/g, '');

// 替换所有双引号
var myStr = myStr.replace(/"/g, '');

// 或者更有趣一点，用双引号替换单引号
var myStr = myStr.replace(/'/g, '"');

// 反之亦然，用单引号替换双引号
var myStr = myStr.replace(/"/g, "'");
