This article will explain in detail the cases of using JavaScript regular expressions to remove double quotation marks. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The specific code is as follows:

/ / var pattern = / [^ "] * /; / / verify whether the string is full of non-double quotation marks var pattern = / ["] + /; / / verify whether there are double quotation marks in the string / / var pattern = / ["] [^"] * ["] / matches 0 or more characters var value1 =" The best things in life are free "within single or double quotation marks / / string without double quotes var value2 = "/" / "The /" best things / "in life are free/" / ""; / / string alert with double quotes ("value1 string without double quotes" + pattern.exec (value1)); / / null alert ("string value1 without double quotes! pattern.exec_2===" +! pattern.exec (value1)) / / true alert ("value2 string pattern.exec_1=== with double quotes" + pattern.exec (value2)); / / "alert (" value2 string with double quotes! pattern.exec_2=== "+! pattern.exec (value2)); / / false if (pattern.exec (value1)) {/ / verify whether the character alert in the string is not double quotation marks (" value1 does not add non-quotation marks + double quotation marks are matched ") } if (! pattern.exec (value1)) {/ / verify whether there are double quotation marks in the string alert ("value1 with plus non-marks + double quotation marks matched"); / / page window pop up} if (pattern.exec (value2)) {/ / verify whether the string is full of non-double quotation marks characters alert ("value2 does not add non-marks + double quotation marks are matched") / / Page window pops up} if (! pattern.exec (value2)) {/ / verify whether there is a character alert in double quotation marks in the string ("value2 with plus and non marks + double quotes matched") } this is the end of the article on "using JavaScript regular expressions to remove double quotes". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
